A Physical Therapist’s Tips To Stay Healthy & Energetic At Work

A Physical Therapist’s Tips To Stay Healthy & Energetic At Work

In every industry, the work culture has changed a lot in the last few decades. Since the time we started using computers, prolonged sitting has become quite common. If you sit in one place continuously for more than a few hours, it leads to health problems.

Perhaps that’s the reason physical therapists always advise people to take short breaks. It not only helps in refreshing your mind but also has a lot of benefits for your physical health.

Whether you work in a high-end office or you spend your time working on manufacturing plants and construction sites, living a pain-free life is essential for one and all. If you are unwell, you can’t perform at your best; therefore, it’s vital to take care of your health. Those who have jobs that require intense physical activity remain at the high risk of workplace injuries.

However, those who have sitting jobs end facing a wide range of problems due to lack of physical movements. You feel pain in your neck, back, shoulders, and arms, etc., after sitting for long periods of time. Besides, some people also experience pain in the wrist, knees, hips, and lower back, etc.

The only way to enjoy a healthy while still performing your duties on time is to consult a physical therapist. Your therapist will not only treat your condition, but they will also educate you.

According to Priority Physical Therapy, “We assess the worker’s current functional abilities and gather information regarding his/ her job requirements. Treatment is both evaluative and restorative. Therapy will utilize a combination of manual therapy techniques, therapeutic exercises, body mechanics training, modalities, and patient education/ home programming.“

So, if you have a full time sitting job, here is how you can maintain your health.

Correct You Sitting Posture 

You can reduce the risk of a variety of health conditions that stem from prolonged sitting by correcting your posture. Always make sure that you sit up straight. If you slouch, then make sure you stop that in the first place. Slouching is a bad habit; therefore, you should always try to avoid it. Most people who slouch end up struggling with spinal problems. They struggle with conditions like neck pain and back pain frequently. Although you get tips to prevent back pain from your family and health professionals; however, sometimes it’s better to use your intelligence as well.

While sitting at your desk, make sure that you keep your back straight, feet flat on the floor, and knees at a 90-degree angle. Besides, you should keep your computer at an eye level, so that you do not have to stretch your neck.

Use An Ideal Chair 

Using the right chair is utterly crucial to keep your spine healthy. Maintaining the actual shape of your spine is highly vital to keep the musculoskeletal conditions at bay. If you are using an uncomfortable chair, ask your boss to replace it with a better one that can offer the right support to your back.

Also, if you are feeling uncomfortable, you can use a footrest. Nowadays, you will find a wide range of office chairs which offer the maximum comfort to employees. You can also use them!

Take Breaks Frequently 

Taking short breaks is an ideal way of keeping your body pain-free. When you get up from your seat frequently, it not only helps in improving your circulation but also makes it easier for you to concentrate on your task once you get back at your desk. Since it helps in refreshing your mind, you can focus on your work. Walking around your office is an excellent way of relieving the compression that results from long hours of sitting.

Stretch Your Body Regularly 

Stretching is very crucial for people with the sitting jobs. They should keep on performing basic stretches that do not take much time. Stretch your neck if you are feeling uncomfortable. Roll your neck in all the directions to relieve tightness. You can also roll your head to the right side and hold that position for at least 15 seconds. Do it again but this time around roll your head to the left side. Besides, you can also stretch your chin all the way to your chest and tuck it.

Similarly, you can carry out upper body stretch and hamstring stretch at work.

Drink Water Frequently

Keeping your body hydrated is utterly vital to stay healthy. Always keep a bottle of water at your desk, so that you can drink it frequently. If you are someone who does not like drinking plain water, you can mix lemon in it. Make sure that before taking the lunch you take enough of water.

It not only helps in reducing the amount of food you consume during the mealtime but also keeps you healthy. It helps in flushing out toxins from your body, strengthens the immune system, and promotes weight loss.

Drinking water frequently helps in preventing dry mouth and bad breath.

Get Your Arc Flash Game On

By Jack Rubinger, jarubinger@graphicproducts.com, www.DuraLabel.com

What happens when an arc flash occurs? And what is being done to lessen the risk? Few topics stir the emotions as much as arc flash dangers.  There is so much energy involved, and the nature of electricity is unlike anything else: invisible and unpredictable. Think burns and severe eye injuries.  

Working smart is critically important though experts agree it’s still hard to anticipate an arc flash occurrence. That’s why it’s so important to be prepared.  The most important question is: “Can we do this work de-energized?” said Mike Balinskas of PowerHawke, Inc. 

“Unfortunately, arc flash studies aren’t an exact science. They are snapshots, based on current utility information. As the grid fluctuates over time, so does the hazard exposure,” said Dave Hill, Intertek Testing. So it’s not enough to rely on PPE. Every precaution should be taken to prevent arc flash.

What’s missing from many electrical safety programs is a strategic game plan to address arc flash hazards.

“The distance between a lifetime of pain, disfiguration, and disability when compared to going home safely is no further than the fraction of an inch air gap that can be ionized to initiate an arc in the presence of significant voltage. Knowing the site and following the rules keep individuals safe and equipment intact,” said Michael Morse, Professor of Electrical Engineering, University of San Diego.

Electrical safety plans must address:

  •         Training/compliance
  •          PPE
  •          Tools/equipment

Training/compliance

Employees fear they’ve not been adequately trained. Training needs to increase to keep employees up to speed. How familiar are you with new NFPA requirements and how they apply to your equipment?

Mr. Hill reviews current arc flash NFPA, ANSI, IEEE and NEC information:

  • NFPA 70-2011/NEC is the driving document for all electrical installations. The other NFPA, ANSI/UL, IEEE, NEMA and harmonized IEC documents refer back to the NEC for installation practices.
  • NFPA 70-2011/NEC Section 110.16 and the Informational Note reference NFPA 70E for guidance of Arc Flash and PPE as well as ANSI Z535.4 for the safety warning signage.
  • Industrial electrical equipment and control panels, are required by NFPA 70-2011/NEC Section 670.3(A) to have a permanent label denoting short-circuit current rating of the control panel with references to UL 508A Supplement SB as an example of determining the SCCR. Section 409.22 and 409.110(4) are the references for industrial control panels specifically.
  • NFPA code calls for labeling electrical panels, disconnects and access points to inform those servicing equipment to communicate potential arc flash hazards present based on studies of the electrical system feeding each location.
  • NFPA 70E requires workers to document arc flash analysis calculations used for electrical equipment labeling. Even though NFPA 70E and IEEE 1584 provide standardized calculations for an arc flash analysis, other methods exist, opening the door for variation. Posting key elements of your analysis on electrical equipment will help you remember the methods used after a job is complete.

As of September 30, 2011 NFPA requires labels to display the nominal system voltage, arc flash boundary and one of the following: 

  • Available incident energy and the corresponding working distance
  • Minimum arc rating of clothing
  • Required level of PPE
  • Highest hazard/risk category (HRC) for the equipment 

NFPA’s new standards require that labels display additional information and must be posted on switchboards, panelboards, industrial control panels, meter socket enclosures and motor control centers.

A switchboard is a large single panel, frame, or assembly of panels. Switches, overcurrent, other protective devices, buses and usually instruments are mounted on the face, back or both. Switchboards are generally accessible from the rear and from the front and not intended to be installed in cabinets.

Panelboards are single panels or groups of panel units designed for assembly in the form of a single panel. These include buses, automatic overcurrent devices and those devices equipped with or without switches for the control of light, heat or power circuits. Panelboards are designed to be placed in a cabinet or cutout box or against a wall, partition, or other support; and accessible only from the front.

There are two main types of industrial control panels (ICP) — enclosed and open ICPs. Enclosed ICPs are installed within a complete enclosure at the panel manufacturer’s location. An open ICP includes factory wiring, field wiring terminals and components mounted on a sub-panel without a complete enclosure. ICPs often contain motor controllers, switches, relays, power supplies, computers, cathode ray tubes, transducers and auxiliary devices used in the manufacturing process to control industrial utilization equipment.

Meter socket enclosures are equipped with matching jaws to accommodate the bayonet-type (blade) terminals of a detachable watt-hour meter. It also has a means of connections for the termination of the circuit conductors. It may be a single-position socket for one meter or a multi-position trough socket for two or more meters.

Motor control centers are unlike other types of power distribution equipment, which are used with a variety of load types. Motor control centers primarily control the distribution of power to electric motors.

PPE 

Whether you are in an underground high-voltage transmission system or a substation, personal protective equipment (PPE) reduces exposure hazards. PPE means wearable protective gear: a shielded hood, bibs or coveralls. 

“A key technology ensuring safety is the infrared window. Installed on cabinet panels and doors, IR windows are view ports providing access into electrical cabinets and other enclosures. With an IR window, an electrical worker uses an infrared camera to inspect energized internal electrical components for temperature abnormalities without the direct exposure from removing covers and panels,” said Andre´ Rebelo, FLIR Systems, Inc. 

Infrared windows are a framed lens made of special transparent crystal or polymer material allowing infrared spectrum waves to pass through the window making it easy to perform infrared inspections. IR windows have a protective cover to shield the lens when not in use. 

Tools and Equipment


Industrial labeling systems such as the DuraLabel Toro are indispensable for electrical contractors. New systems are mobile, compatible with many types of software and empower end-users to quickly create custom safety, hazard and warning signs and labels on-site, in sequence. Displaying arc flash calculations on an industrial label offers valuable information to other electrical workers, inspectors and emergency responders who will likely work on or around the equipment you label in the future.  

No one can dispute the power and force of an arc flash. Following these three strategic steps, we can minimize many arc flash hazards.

MORE ABOUT GREEN JOBS

As countries strive to develop newer energy sources, “green” jobs have emerged.  We hope you have read our articles on wind energy, solar power, green roofs, and biofuels.  Two more fields that we will talk about are Hydrogen Fuel Cells and Geo-Thermal Energy.  Working in either of these jobs present the same risks that we see in many other occupations.  

Fuel Cells use hydrogen in producing electricity, and electricity is generated as long as this hydrogen fuel is supplied to it.  A fuel cell is an electrochemical device that produces electricity without combustion.  In 1839, Sir William Grove invented the first fuel cell.  Knowing that water could be split into hydrogen and oxygen by sending an electric current through it (electrolysis), he theorized that by reversing that procedure electricity and water could be produced.  His primitive fuel cell was called a gas voltaic battery.  Fifty years later, scientists coined the term fuel cell while attempting to build a more practical model to produce electricity. 

A fuel cell provides a DC (direct current) voltage that can be used to power motors, lights, and any number of electrical appliances.  Fuel cells compete with many other energy conversion devices, including the gas turbine in a city’s power plant, gasoline engines in cars and batteries in laptops.  Combustion engines like the turbine and gasoline engine burn fuels and use the pressure created by the expansion of the gases to do mechanical work.  Batteries convert chemical energy back into electrical energy when needed.  Fuel cells should do both of these tasks more efficiently.

Typical hazards that workers in the Hydrogen Fuel Cells industry are exposed to include:

  • Fire and explosion – hydrogen is flammable gas and must be handled properly.
  • Freeze burns – liquid hydrogen is very cold (-423°).
  • Electrical – arc flash hazard or electrocution. 

Geo-Thermal Energy is rapidly growing throughout the United States.  We recover the heat as steam or hot water  from within the earth’s core, and  use it to heat or cool buildings or generate electricity.  It is a renewable energy source because heat is continuously produced inside the Earth.  Certain geothermal energy systems pump water underground through piping, allowing it to be heated by the earth, and then use the hot water to create electricity.  Temperatures hotter than the surface of the sun are continuously produced inside the earth by the slow decay of radioactive particles, a process that happens in all rocks.  Other methods of recovering the earth’s heat is by drilling directly into the Earth’s natural geothermal reservoirs, using the resulting steam and hot water to create electricity.  Some systems use a brine or saltwater solution while others use glycol.  These solutions may pose hazards of their own to workers. 

Hazards associated with this growing industry include some very familiar safety issues that OSHA already has standards on:

  • Trenching and excavations – soil for heat transfer may not be best for stable trenches.
  • Silica – silica sand is a basic component of soil, sand and granite.  It becomes airborne as workers chip, cut or grind objects that contain crystalline silica.  Silica dust is a serious hazard.
  • Electrical –   Workers should use same safe practices as in other electrical fields.
  • Welding and cutting – the same hazards that welders face in any pipe-fitting or welding projects – burns from hot metals, and exposure to ultraviolet light from arc welding.
  • Fall protection – open trenches, excavations, and pits should have guardrails or barriers, safety nets, or personal fall arrest systems. 

We understand that workers must have all the proper personal protective equipment needed to match the perils of each particular job.  Personal protective equipment required for these jobs include gloves, safety glasses, hardhats, particulate respirators, and other products, (including the proper gear for welders), as determined by the contractors’ safety engineers.  

While green jobs help to improve the environment and we are grateful for technology to develop other energy sources, some commonly known workplace hazards exist, while others are yet to be identified.  As green jobs progress into excellent energy resources, safety still must be a priority for the workers performing their duties.
