IT MAY BE TIME FOR A WELD FUME AUDIT (GUEST POST)

As many welders know, one of the most important aspects of the job is to protect themselves from weld fumes and the toxicity associated with these externalities. To avoid health risks, weld fume exposure levels should be checked periodically to be certain that the levels fall within Occupational Safety and Health Standards Association’s (OSHA) acceptable exposure limits and the American Conference of Government Industrial Hygienists’ (ACGIH) threshold limit values. 

While the amount of audits depends on the size of the company and the amount of welding, weld fume audits should be done regularly. Even though every welding environment is different, these must be evaluated by a Certified Industrial Hygienist (CIH) to determine the appropriate course of action for fume controls (if any). The CIH will monitor the air in your facility and offer consultation on necessary next steps. 

Welding different materials gives off large amounts of heat, light, and gas. This exchange can release hazardous gases and fumes, not visible to the eye. Over the years, studies have found that welding stainless steel can cause occupational asthma. This occupational asthma is not only linked to stainless steel, non-stainless steel welding can actually be more problematic as occupational asthma has been reported without any specific agents determined as the cause. 

While the list of health hazards linked to weld fumes is ongoing, many are associated with respiratory issues.  Lung and skin cancers are also linked to overexposure of metal fumes, over long periods of time. With eye and skin irritation rounding out the less invasive illnesses related to dangerous weld fumes. 

When an audit is performed, the CIH will check for acceptable levels of hexavalent chromium Cr(VI). If an audit shows levels of Cr(VI) higher than OSHA’s Permissible Exposure Limit (PEL), then further action must be taken. While this action varies upon the company size and exposure levels, there are items on the market today that offer preventive maintenance along with long-term improvements in air quality. One product sold by Lincoln Electric is a fume extractor that’s an in-house standalone system used to continuously filter the air, in order to extract welding fumes released during the fabrication process. These extractors can also be modified to force ventilation through the roof or wall fans. Another in-house option is the use of detection panels. These panels are often used with the extraction systems in order to prevent, detect, and suppress fires in the welding and fume extraction equipment. 

Outside of installation, individual responsibility is also paramount to keep people safe from weld fumes. It’s important that you know how to protect yourself. Facilities need to have good ventilation, perform air quality tests, and determine if a respirator is necessary for the task. Whether or not your facility is at risk for Cr(VI)exposure, it’s crucial to stay informed about exposure and the risks involved with welding. Proper preventive measures can be substantial in hindering the dangerous health risks associated with the incidental inhalation of weld fumes.

SAFETY TIPS FOR DECONTAMINATION FOLLOWING DISASTERS

1 Comment

Waters after hurricane/flood/tornadoes can be contaminated with sewage, industrial waste, microorganisms, chemicals, and other substances that can cause illness or death.  In these environments, it becomes necessary for professional rescue workers, along with volunteers, to begin the tasks of decontaminating the properties that are still standing.  An important step in preventing disease is to disinfect clothing, tools/equipment, and work area surfaces.  

Good old household bleach solutions can be used for decontamination purposes when working around these hazards.  It is important to workers and volunteers that good hand hygiene is established.  Hands should be washed with clean soap and water if at all possible.  If only contaminated water is available, use ¼ cup of bleach per 1 gallon of water.  When cleaning hand tools, immerse them in the solution.  Severe surface decontamination needs to be disinfected using a solution of 1½ cups of bleach to 1 gallon of water.  Allow this to stand 3 minutes. 

It is important to mix bleach solutions fresh daily, just before use.  The solution needs to stand for 30 minutes before using.  Wipe electric or battery-operated tools with bleach solution.  It is also imperative that you wear gloves, and eye protection when cleaning clothes, tools, and surfaces.  When mold is present, use respirators (N-95 recommended).  Never mix ammonia products with bleach. 

An Added Problem 

Emergency responders don’t often consider technical animal decontamination, yet the possibility absolutely exists.  Common HAZMAT situations involving animals include septic tank falls, inadvertent chemical overspray, swamps, flooding, and gasoline from automobile and trailer wrecks.  Animal handling and decontamination is an integral part of any HAZMAT response where animals are potentially exposed to hazardous chemical releases. Contaminated animals pose a health and safety threat to any human they contact after removal from a hazardous environment if they are not properly decontaminated.  This requires proper training and equipment for first responders and well thought out plans for animal management before, during and after the decontamination process.  Sights of deserted animals are heartbreaking, and there are rescue agencies that take them in and rehabilitate them, finding new owners if the original owners are not found. 

Because there is such a threat of disease, all precautionary measures should be taken by workers, volunteers and homeowners.  Wearing proper PPE personal protective equipment for different situations is of the utmost importance.

WORKING WITH ASBESTOS? READ THIS! (GUEST POST)

By Joe McRobert
 
Asbestos is known as the ‘hidden killer’; it is generally not in plain sight, for example, you would find it in walls and ceilings, and it can be very dangerous. It can cause a number of diseases that could potentially be fatal, including Mesothelioma and Asbestosis. These diseases can be caused if the asbestos fibres are inhaled. This is why you need to be fully equipped when you are working with it. It is not always easy to identify either, so this makes it even more dangerous.
 
So if you are already working with asbestos or you are going to be, then you need to have all of the equipment to make sure you are safe. Here is a list of the equipment you need to ensure you are fully protected from the hidden killer.
 
Overalls
You will need overalls to cover the clothing you are wearing otherwise your clothing will be exposed to the asbestos fibres; not only would this be dangerous for you, it can also be dangerous for others near you as they may also inhale the fibres. You need to make sure you are fully covered, so you should avoid tucking your overalls into your boots because dust could get into your boots and you should avoid wearing long-sleeved t-shirts because they are more difficult to cover. You should be supplied with disposable overalls. One thing you should always remember is to not take home the used overalls!
 
Respiratory Protective Equipment
If you are going to be working with asbestos, then this is one of the most important items that should be provided. The respiratory protective equipment will allow you to breathe without the risk of inhaling the asbestos fibres, however you should make sure it is fitted correctly. If it is not fitted correctly, then you could still be at risk of inhaling the deadly fibres; once you have properly fitted your protective mask, you should then put the hood of the overalls up to cover the straps of your mask.
 
Gloves
Another very important item that should be worn every time you are going to be dealing with asbestos is gloves. Disposable gloves are the best for dealing with asbestos because you can dispose of them as soon as you have finished you job.
 
Footwear
Boots are the best type of footwear you can wear when working with asbestos; however, you should avoid wearing laced boots because they are more difficult to clean. The laces on your boots will be exposed to the fibres and you could potentially spread asbestos fibres outside of the workplace. Just make sure your overalls go over the top of the boots to avoid any dust entering your footwear.
 
Protect yourself from the hidden killer and make sure you have everything you need to safely complete the job. Remember that working with asbestos is a dangerous job and you need to be careful. Once you have prepared yourself for the job, you should then make sure anyone you are working with is also prepared. However, if you are ever exposed to asbestos, then be sure to seek medical advice and contact a solicitor, for example Flint Bishop Solicitors, to guide you through your next steps.

PROTECT YOURSELF WITH SAFETY EQUIPMENT FOR ASBESTOS REMOVAL (Guest Post)

2 Comments

Posing a serious health hazard, asbestos removal is a necessary process to ensure that the inhabitants of the home are safe from health complications. Asbestos is not just toxic; it is also a silent killer. Asbestos fibres are very light and often too small to be noticed by the naked eye. They can even float in the atmosphere for months and inhaled by unassuming victims. This makes it even more important to let professionals take care of asbestos removal in your home.  Before starting with the removal, there are many safety measures that should be attended to. Here are the essentials of safety equipment that are a must when removing asbestos.      

Respirators 

They are used to purify the air when working around asbestos. Covering mainly the nose and mouth, respirators filter out the asbestos and allow you to work safely around it. It is important that the respirators fit your head perfectly as even small air gaps can cause asbestos poisoning. Ensure that you are clean shaven to allow the mask to seal your head properly. 

At all costs, avoid using paper dust masks as they cannot filter the small asbestos fibres, causing unnecessary harm to your health. Check with your doctor if you can wear respirators. 

PPE (personal protective equipment) 

Ensure that all persons working inside the containment area wear safety equipment. Apart from protecting your lungs, it is also important to cover your face and body from asbestos. Prolonged exposure to asbestos has known to cause innumerable complications in the health of workers. 

PPE includes safety goggles to protect your eyes, disposable coveralls and gloves to protect your body from debris, and rubber boots to shield your feet from sharp objects. For optimum comfort and protection, opt for laceless rubber boots and ensure that they are thoroughly cleaned after each project. 

Large plastic sheets 

It is a good idea to line the containment area with large plastic sheets. For best results, choose 2 or 3 mil sheeting for the walls and 6 mil sheeting for the floor. Purchase at least one and half times the required amount to ensure that you cover surfaces comfortably. Use good duct tape to seal the corners and joints of the sheeting. 

Tank sprayers 

When removing asbestos, it is essential to keep it wet. Dry asbestos can come loose and risk affecting the workers and neighbours. Tank sprayers help asbestos stick to the wall during the removal. 

Large disposal bags 

The disposal of asbestos is as important as proper removal. All materials exposed to asbestos during the removal process should be safely disposed to prevent contaminating the home and the neighbourhood. Choose 6 mil disposal bags specially designed for asbestos and ensure that the bags are about 33″x50″ in size. It is a good idea to purchase about 4-5 bags for each 100 sqft of ceiling material.

DOES YOUR WORKPLACE LEAVE YOU BREATHLESS?

Millions of people experience allergies caused by everyday exposures to agents such as dust mites, cat dander, and pollens.  Workers who encounter agents can also develop allergic reactions such as asthma, nasal and sinus allergies, hives, and even severe anaphylactic reactions.  Work-related asthma, which is caused by exposure to an agent in the workplace, is the most common occupational respiratory disorder in developed countries.  An estimated 15% of asthmatic cases reported in the United States are occupation-related.  In Canada, asthma affects over three million citizens.  Many are not aware that certain agents at their work place could lead to hyper-responsiveness of airway or aggravating pre-existing asthmatic symptoms.  Because of that, it is likely that the cases of occupational related asthma are under reported. 

Asthma is a common lung disease that creates narrowing of the air passages, making it difficult to breathe.  It can affect your ability to work, and your overall quality of life.  When asthma is not managed, it can even threaten your life.  If you are exposed to certain workplace chemicals or agents, you may be at risk for developing occupational asthma.  Many people with work-related asthma don’t realize that their symptoms are related to their work because they are the same as those for regular asthma: attacks of difficult breathing, tightness of the chest, coughing, and wheezing.  In work–related asthma, the symptoms are worse on workdays and improve when the person is away from the workplace, such as on the weekend, days off, and vacation.  Also, symptoms may be more severe at the end of the week, as compared to the beginning of the week. 

Risk factors for occupational asthma include frequent exposure to the agents involved, allergies, family history of allergies, or asthma, and smoking.  A good clinical history will help in identifying the possibility of work-related asthma.  An occupational physician could carry out a walk-through survey in the workplace to identify the possible agents that cause asthmatic attack.  Also, a look at the list of chemicals in Material Safety Data Sheets (MSDS) would give a clue to that. 

There are many agents that can cause occupational asthma.   Here are some examples:

  • Certain chemicals;
  • Metals and metal-working fluids;
  • Dyes, drugs, and enzymes;
  • Grains, flours, plants, and gums;
  • Natural rubber latex;
  • Animal and shellfish proteins;
  • Fungi;
  • Wood dusts, including red cedar.

Factors that can trigger work-aggravated asthma:

  • Vapors, gases, dusts, mists, sprays or fumes from industrial materials and cleaning products;
  • Dust mites or mold/fungal spores;
  • Indoor air pollution resulting from poor ventilation;
  • Outdoor air pollution and smog (for outdoor workers). 

Both employers and employees can help control or prevent work-related asthma.  Employers should:

  • Eliminate the asthma-causing agent from the workplace.
  • If elimination is not possible, substitute a less hazardous agent.
  • Apply administrative controls such as policies, procedures, safe work practices, and job rotation to minimize exposure time of workers.
  • Control the exposure.
  • Install ventilation systems to contain emissions, such as gases or vapors at the source.
  • Provide Personal Protect Equipment, such as breathing respirator masks.  PPE should not be used as the only method of exposure control when exposures are ongoing.
  • Train employees on the proper use, storage and maintenance of PPE, proper handling procedures, avoidance of spills, and safe working and good housekeeping procedures.
  • Monitor the exposure level of hazardous agents in the workplace. 

Employees should:

  • Learn about the hazards in your workplace by speaking to the employer, health and safety or union representative, or an occupational health professional.
  • Be aware of the symptoms of work-related asthma.
  • Use PPE that is provided.
  • Report any problems with equipment, PPE, or ventilation systems to the supervisor.
  • Attend training courses on work-related asthma and occupational health and safety, and participate in all health and safety programs in the workplace. 

If not recognized and treated early enough, work-related asthma is a serious illness that can result in disability and job loss. Fortunately, when potential hazards are recognized, work-related allergies and asthma can often be prevented, or their effects minimized. Employers and employees must work together to prevent work-related asthma, so all can breathe easy at work.

Respiratory Safety

PROTECT YOUR LUNGS THIS WINTER!

With cold weather, there are many more workers moving indoors, so this is a good time for employers to check the air quality of their employees’ work environment.  This is also the opportunity for employers to inventory their supply and usage of NIOSH-approved respirators.  It is very important to know the hazardous airborne particles that exist in every workplace. 

In the United States, there are an estimated 5 million workers who are required to wear respirators in 1.3 million workplaces.  More people still die from lung cancer than from any other type of cancer (over 159,000 deaths per year).  Smoking is usually found to be the leading cause of lung cancer; however, workers who wear respirators are better protected from harmful airborne hazards.  Some of these hazards have also been known to contribute to causing cancer, lung impairment, other diseases or even death. 

“Dust Masks” vs. N95 Respirators 

Many people often ask what is the difference between a respirator and a dust mask.  Even though their appearances are similar, NIOSH-approved N95 respirators are very different from dust masks.  Dust masks provide no proven protection against harmful airborne particles.  NIOSH recommends the use of N95 (or better) respirators for most environmental hazards. 

In testing, respirators that collect at least 95% of the challenge aerosol are given a 95 rating.  (99% receive a 99 rating; at least 99.97%, a 100 rating).  The filters for respirators are tested by NIOSH at the time of application and periodically afterward to ensure they continue to meet the certification.  The certification of N95 will be on the respirator, so you know you are getting the right thing. 

It is necessary to perform fit tests to verify there are no defects in the respirators.  Please note:  Caution:
Respirators must be properly selected and fitted to provide protection to the user. It is the responsibility of the user to make the appropriate choice of respirator based on the contaminant, workplace concentrations, and any other site specific conditions. It is also the responsibility of the user to ensure that the workplace is in compliance with all applicable Federal, State, and Local regulations on worker safety, including, but not limited to, OSHA regulations on respiratory protection (29 CFR 1910.134). Read all Warnings and Use Instructions that accompany the respirators. If you have any Technical questions regarding respiratory protection, call the manufacturer.

Dust Masks are loose-fitting filters that fit over the nose and mouth, capturing dust on the outside when the wearer breathes in air.  Respirators have the NIOSH marking on them; therefore, they have met strict criteria and passed independent certification tests established by NIOSH.  Their tests ensure the respirator has been designed to meet minimum filtration requirements as well as specific manufacturing quality levels.  NIOSH does not test or certify dust masks. 

Every worksite has its own level of protection that is required for its specific application.  You see respirators used in all types of settings, from the medical industry to industrial applications.  The NIOSH website (www.cdc.gov/niosh) maintains a database of all NIOSH-approved respirators for user reference.

SCIENCE LESSON FOR THE DAY: KEEPING OUR LUNGS HEALTHY

2 Comments

One of the most important things we can do for good health is to protect our lungs.  Smokers probably don’t want to think about it, but we should do everything possible to be able to breathe easily!  I looked up a few words that pertain to helping those with work exposure to respiratory hazards, and want to share what I learned.  Those who are involved probably already know all about the subject, but for those who don’t, bear with us. 

According to McGraw-Hill Science & Technology Dictionary, spirometry is the measurement, by a form of gas meter, (spirometer) of volumes of air that can be moved in or out of the lungs.  Spirometers are instruments used to test lung capacity; spirometry is the gold standard for diagnosing and monitoring the progression of C.O.P.D.  Spirometers can be stand-alone, diagnostic PC-based, or pocket-sized.  Chronic Obstructive Pulmonary Disease is the 4th leading cause of death in the U.S., affecting more than five per cent of the adult U.S. population. 

Respiration, according to Briticannica Concise Encyclopedia, is the process of taking in air for oxygen and releasing it to dispose of carbon dioxide.  The amount of air inhaled and exhaled in an average human breath is about one-eighth the amount that can be inhaled after exhaling as much as possible.  Nerve centers in the brain regulate the movements of muscles of respiration (diaphragm and chest wall muscles).  Blood in the pulmonary circulation brings carbon dioxide from the tissues, to be exhaled and takes up oxygen from the air in the pulmonary alveoli to carry it to the heart and the rest of the body.  Because the body stores almost no oxygen, interruption of respiration – by asphyxiation, drowning, or chest muscle paralysis – for more than a minute can cause death. 

Spirometry Monitoring Technology

From the Centers for Disease Control, spirometry monitoring is recommended for persons with occupational exposure to respiratory hazards, and is best done as part of an overall health maintenance program in which results of spirometry evaluations are linked with exposure control, smoking cessation, and general health-promotion interventions. Spirometry monitoring should be done to prevent development of disabling chronic lung function impairment through early intervention on excessive lung function loss. Spirometry plays an important role in an occupational respiratory health surveillance program. It can assist the health professional by determining if a worker demonstrates a specific pattern of respiratory impairment and can help to assess the effectiveness of measures implemented to protect the individual worker. In addition, results from defined groups of workers can be evaluated in relation to potential workplace hazards.

Protecting the health of individual workers is a primary objective of various workplace surveillance programs. Results from an individual should be further assessed if abnormalities are detected or if pulmonary function values show an excessive decline in comparison to the individual’s previous tests. After ruling out technical causes for low or declining pulmonary function, efforts must be made to identify the cause. If the cause is related to a workplace exposure, then steps must be taken to better control or eliminate the exposure and prevent further damage to the worker’s lungs.

 NIOSH recommends the use of half-facepiece particulate respirators with N95 or better filters for airborne exposures to crystalline silica at concentrations less than or equal to 0.5 mg/m3. The Occu­pational Safety and Health Administration (OSHA) also specifies the use of at least a 95-rated filter efficiency [29 Code of Federal Regulations (CFR) 1910.134]. The recommendation for a 95-rated filter efficiency reflects the improved filter efficiency of N95 filters over the earlier dust and mist (DM) filters. A comprehensive respirator program must be instituted prior to the use of 42 CFR 84 respirators. The requirements for a comprehensive respirator program are included in the OSHA respiratory protection standard (29 CFR 1910.134).

Monday, September 26, 2011, National Mesothelioma Awareness Day 2011, carries special meaning, because mesothelioma is a relatively rare form of cancer that strikes as many as 3,000 Americans each year. A common cause of mesothelioma is asbestos exposure. Victims tend to be electricians, plumbers, contractors, or armed forces veterans – anyone who worked with or around asbestos. The condition develops decades after exposure, but the disease can prove fatal within a year of diagnosis. At present, there is no cure.  Sadly, family members also often fall prey to mesothelioma as a result of secondary exposure to asbestos fibers carried into the home by the primary victim.  That’s why it is very important for the worker to shower and change clothes before leaving the worksite. 

This article wasn’t meant to be “long-winded,” however, we want employers and employees to realize the importance of well-planned and executed programs for respiratory protection.  (After all, science lessons are very important!)

Respiratory Safety

BREATHE EASIER WITH RESPIRATORY PROTECTION

Number 5 on our  “Hit Parade” countdown of OSHA’s Top Ten violations for 2010 is Standard 29 CFR 1910.134,  Respiratory Protection, General Industry.  According to the Centers for Disease Control, respirators protect the user in two basic ways. The first is by the removal of contaminants from the air. Respirators of this type include particulate respirators, which filter out airborne particles; and “gas masks” which filter out chemicals and gases. Other respirators protect by supplying clean respirable air from another source. Respirators that fall into this category include airline respirators, which use compressed air from a remote source; and self-contained breathing apparatus (SCBA), which include their own air supply.  Respirators should only be used when engineering control systems are not feasible. Engineering control systems, such as adequate ventilation or scrubbing of contaminants are the preferred control methods for reducing worker exposures. 

If you work where there is dust, heat, humidity, or mist around you, respirators are needed.  Respiratory protection is regulated by OSHA, which determines which type of respiratory protection is appropriate for each kind of hazard.  NIOSH regulates the manufacture and testing of face masks/respirators, labels them for the appropriate type of use, and OSHA is responsible for their use.  Employers are in charge of establishing and implementing a written respiratory protection program with worksite-specific procedures and elements for required respirator use.  The provisions of the program include selecting the correct protection, medical evaluation, fit testing, training, use and care of respirators.  Persons with mustaches or beards may not be able to get a secure fit.  OSHA requires fit-testing, to be sure there are no leaks.  Respirators Fit-testing kits must be used to ensure their compliance to safety requirements. 

N95 filtering respirators, “air purifying respirators” cover the nose and mouth.  A respirator classified as N95 means that 95% of most penetrating particulates will be filtered out. This type of respirator protects the wearer against breathing in small particles that contain viruses, such as in a healthcare setting.  For other occupational exposures, the respirators filter out dust, mist, heat and vapors that can be harmful to your health.  To be fully effective, N95 respirators must fit closely to form a light seal over the mouth and nose.   Manufacturers make several different sizes of respirators to accommodate smaller faces.  The use of powered air-purifying respirators may be chosen as a suitable type in some cases. 

Workers must have received comprehensive and understandable training at least annually, and more often if necessary.  This training should include, at a minimum:

  • Limitations and capabilities of the respirator;
  • Effective use in emergencies;
  • Why it is necessary and how improper fit, use and maintenance can compromise its protective effect;
  • Recognition of medical signs and symptoms that may limit or prevent effective use;
  • How to inspect, put on and remove, use and check the seals;
  • Maintenance and storage.

Listed among the top five violations by companies in the United States is an indicator that employees are being exposed to hazards that can be very harmful to their health.  We hope by this time next year,  most of the serious violations will be corrected, and that respiratory protection will be taken off the list.  We’ll all breathe easier when this happens, especially our workers!

OCTOBER IS “HEALTHY LUNG MONTH!”

The American Lung Association has declared October – “Healthy Lung Month.”  Because our lungs are a very important part of our respiratory system, we need to do all we can to keep them healthy.  Bacteria, viruses, tobacco smoke, air pollution, chemicals – any of those things that we breathe can damage the airways and threaten to cause the lungs to not work properly. 

The air we breathe affects us at home, school, work, or outdoors.  Because the environment is full of pollutants, the media even gives us warning of pollen counts and other breathing hazards on a daily basis.  The United States Environmental Protection Agency (E.P.A.), Occupational Safety and Health Administration, (dictates standards to protect workers’ lungs), and National Institute for Occupational Safety and Health, (researches and generates knowledge of work-related illness), all are working to educate and enforce the importance of safety issues such as air quality for America’s workforce. 

In the workplace, respirators are an important tool of personal protective equipment to aide workers who must breathe in pollutants such as dust, chemicals, gases, fumes, oil-based aerosols, asbestos, and other air-borne particulates.  Respirators are also used in healthcare settings, such as hospitals, and by EMS/EMT, fire and rescue, school healthcare, industrial and manufacturing industries. 

Dust masks are loose-fitting filters that fit over the nose and mouth, capturing dust on the outside while the wearer breathes in air.  Respirators will have NIOSH marked on the outside, meaning they have been tested and certified.  There are many types of designs and uses of respirators.  The type of respirator to be selected depends on the hazards of each particular setting.  There are an estimated five million workers in the U.S. that are required to wear respirators in 1.3 million workplaces in the United States. 

 There are more than 159,000 deaths in the U.S. per year from lung cancer, the leading cause of cancer, according to the Centers for Disease Control.  Although smoking is thought to be the leading cause of lung cancer, those workers who wear respirators are better protected from airborne hazards – many of which have been known to cause cancer, lung impairment, asthma, and other diseases, or death.   Last year, because of the H1N1 virus, respirators were in high demand.  I know several persons who wear a respirator when they travel, to avoid catching a “bug.”

It is important that employers take the time to check the air quality of the environment their workers are in every day.  Respirators should be selected and tested on each worker for proper fit.  The choice must be based on the workplace contaminants, concentrations, and all other specific conditions.  All selections should be compliant with State, Federal, and Local regulations on workers safety including but not limited to OSHA regulations on respiratory protection (29CFR 1910.134.)  Some respirators are suited for environments free from oil-based contaminants.  Others are used for types of gases, fumes, oil-based aerosols, and asbestos. 

We need to start our children out with healthy lungs, by keeping our homes properly ventilated and smoke-free.  It’s harmful for children to have to ride in a car that is full of smoke.  Outdoor activities are important for kids and adults, too, so report any locations that may cause pollution in your neighborhood.  Next, we need to be sure that their schools have healthy atmospheres.  They should be built with adequate ventilation and be cleaned regularly.  School buses may contribute to air pollution. 

Focus on good health for you and your family.  Keeping your lungs nice and pink is a smart thing to do.  Too many times we need to stop and take a deep breath, and if your lungs aren’t in good shape, it’s hard to do.

Respiratory Safety

RESPIRATORS HELP YOU BREATHE EASIER

If you work in a healthcare setting, or where there is dust, heat, humidity, or mist around you, respirators are necessary.  Respiratory protection is regulated by OSHA, which determines which type of respiratory protection is appropriate for each kind of hazard.  NIOSH regulates the manufacture and testing of face masks/respirators, and OSHA is responsible for their use.

Masks used by healthcare workers may be surgical, procedure, isolation, dental, or laser masks.  These masks trap germs and resist fluids.  Surgical masks protect the employee from microorganisms, body fluids, and large particles in the air.  They cover the mouth and nose loosely and are not sized for individual fit. Good hand hygiene must be practiced, such as washing hands before putting the mask on and taking it off.

N95 filtering respirators, “air purifying respirators” cover the nose and mouth.  A respirator classified as N95 means that 95% of most penetrating particulates will be filtered out. This type of respirator protects the wearer against breathing in small particles that contain viruses, such as in a healthcare setting.  For other occupational exposures, the respirators filter out dust, mist, heat and vapors that can be harmful to your health.  To be fully effective, N95 respirators must fit closely to form a light seal over the mouth and nose.  Persons with mustaches or beards may not be able to get a secure fit.  Respirators require fit-testing, to be sure there are no leaks.  There are fit-testing kits that are used to ensure their compliance to safety requirements.

Due to the fact that respirators are made of more dense material than facemasks, persons who have heart disease, lung disease, or other respiratory illnesses should consult a healthcare provider before using a respirator.

In cases of widespread illness, such as pandemic influenza, it is wise for persons who act as family caregivers or have to be in public transportation, etc., to stock up on these protective masks.
