NATIONAL SAFETY MONTH WEEK 3: OVEREXERTION

What better time to focus on overexertion than at the beginning of warm (hot) weather?  Those who haven’t been exercising during the winter season may have decided to start working out to get back into shape.

Usually the first thing we think of is “no pain, no gain”.  But this is not the correct way to reach our goals.  Going beyond what our bodies can do usually brings about harmful results.  If you are working out at home or a fitness center, get some good advice from a trainer and pace yourself.  When exercising, if you are breathing heavily for a lengthy time, stop, and try something else.  Know your limits.  Swimming is an excellent aerobic activity.

Health problems can also be brought about because of overexertion.  Heat stroke can occur when a persons’ body cannot control its temperature.  If you are exerting yourself physically, there is a danger of heat stroke at a temperature as low as 75°, if the humidity is high.  Although not as serious as heat stroke, heat cramps and heat exhaustion also can pose threats when a person perspires heavily and becomes dehydrated.  One needs to get in the shade, drink non-caffeine or non-alcoholic drinks, and if possible, take a cool shower or sponge bath.  Because the body loses salt through perspiration, cramps happen.

Other forms of overexertion, such as back strain, are a leading cause of workplace injuries, resulting in almost 3.5 million injuries per year.  Overexertion is sometimes linked to overachievement.  Doing a physically exhausting job too long harms our bodies.  Employers should consider the temperature extremes their employees are exposed to.

The following ideas are usually included in safety training of employees, but let’s review them:

  • Proper lifting techniques.
  • Have carts, wheelbarrows, or other equipment available.
  • Use of gloves for better grip.
  • Push, don’t pull load.
  • Good footing.
  • Don’t reach too far for something.
  • Don’t try to jump.

There are many other suggestions to help avoid overexertion.  The main thing is to use common sense.  Your body has a great warning system, and will let you know when you are overdoing it.  Pay attention!

HOT TIPS ON HEAT STRESS

1 Comment

During the summer months, workers who are exposed to extreme heat should recognize symptoms of heat stress, and how it can be prevented.  Things that can lead to heat stress are: inadequate water intake, physical exertion, direct sun, high temperature or humidity, and some medicines.  Workers should stay hydrated and maintain a safe core body temperature, which should never exceed 100°F.  Ingesting fluids on a regular basis also puts less strain on the cardiovascular system.

Signs of heat disorders are:

  • Heat Stroke – This is the most serious heat related disorder.  Confusion, irrational behavior, loss of consciousness, lack of sweating (usually), an abnormally high temperature are primary signs of heat stroke, resulting in a medical emergency.  The worker should be doused with cool water and given fluids.  Drinks that contain alcohol, caffeine or large amounts of sugar can cause workers to lose body fluid, and very cold drinks can cause stomach cramps.  Cool fluids are easier to drink and more easily absorbed into the body.
  • Heat Exhaustion – This is the result of a combination of dehydration and excessive heat.  Headache, nausea, dizziness, weakness, giddiness, and thirst are symptoms.  Workers with heat exhaustion should be given fluids, and encouraged to rest.  Workers can stay hydrated by keeping containers of fluids handy at all times.
  • Heat Cramps – Caused by an electrolyte imbalance caused by sweating and lack of water replenishment.  Workers in hot environments should drink water every 15 to 20 minutes and drink carbohydrate-electrolyte replacement liquids (e.g., sports drinks).
  • Heat Rashes – Most common problem where skin is persistently wetted by sweat.  Creams or ointments should not be used as they keep the skin warm and moist, and may worsen the condition.  Powders may be applied.

A reminder to workers: be sure to drink fluids before becoming thirsty; if you wait, your body is already dehydrated.  Wear a wide brimmed hat if your work doesn’t require a hardhat, use sunscreen, and wear OSHA approved safety glasses that have the proper UV protection.  There are many other products on the market to help you “keep your cool”.
