What is a risk assessment

HEAT DISORDERS QUIZ - ANSWERS

1. What signs and symptoms might you notice if your body is too hot?
• First, you may notice that you are tired and less mentally alert.

This increases the danger of accidents.

• You may sweat. The body produces sweat so the evaporation will cool you off.

Sweating isn’t as effective if the air is very humid, because not as much sweat
 evaporates.

• Heat rash is possible. You get it when your sweat glands swell and get plugged up.

• You can get sunburn if you’re in direct sunlight too long without using a sunscreen
product on your skin. Sunburn can be painful and may even lead to skin cancer.

2. If you don’t pay attention to these early symptoms and get out of the
heat,

you can get heat disorders.

What does heat stress do to your body?

• The first symptom is usually heat cramps. If you don’t replace the fluids and

salts (called electrolytes) that you lose by sweating, you may get muscle

pain or muscle spasms. These are most common in the arms, legs, back,
and

stomach.

• Heat exhaustion can follow. Your whole body (especially your circulatory

system) is extremely stressed. Some possible symptoms are:

— Pale, flushed face and neck — Shortness of breath

— Clammy skin — Headache, dizziness, or fainting

— Heavy sweating — Nausea and vomiting

— Fatigue — Rapid heartbeat and breathing

• Heat stroke is the most serious stage of heat disorders. Your body
temperature

shoots up. 50% of people with heat stroke die. Symptoms are:

— Dizziness and confusion — Rapid pulse

— Red, hot, dry skin — High body temperature (around 105° F)

— Nausea and vomiting — Convulsions

— Very little sweating — Fainting

Note: Anyone with heat stroke must be taken to a doctor or hospital
immediately.
3. What’s the best treatment for the different stages of heat disorders?
• Heat cramps — Stop work, drink fluids, and rest in a cool area. Drinking
electrolyte solutions may also help.

• Heat exhaustion — Give first aid by moving the person to a cool place to rest.

Remove as much clothing as possible. Give the person water. Drinking electrolyte

solutions may also help. Don’t allow the person to get chilled, and treat for shock
if necessary. Get medical help.

• Heat stroke — Call 911 to get an ambulance immediately. Immerse the

person in cool water or ice.

4. Some people are more likely to get heat disorders than others. Why?

• You have a higher risk of heat disorders if:

— You are not physically fit.

— You are overweight.

— You have a chronic illness like heart disease or diabetes.

— You drink alcohol or take drugs (either illegal drugs or prescription drugs).

— You are dehydrated—from diarrhea, a fever, or not drinking enough water.

— You wear heavy or tight clothing.

— You wear some kinds of personal protective equipment (PPE) on the job.
Some PPE (like a full body suit) is hot. Other PPE (like a respirator) increases the
stress on your body in other ways, making it harder for the body to fight the
heat.

— You are not used to working in heat. The more you work in heat, the more

your body gets used to it. This is called becoming acclimatized to heat.

5. How long does it take to become acclimatized?

• It usually takes 4 to 7 days of regular exposure to heat. But everyone is

different.

• You shouldn’t do strenuous work all day on a hot job until you’ve become

acclimatised.

• When you are acclimatized, your body temperature and heart rate will be lower.

You will sweat more, but your sweat will be less salty so you won’t lose as

much salt.
 • You lose acclimatization in a few weeks if you stop working in the heat.

6. What precautions do we need to take on the site to prevent heat

disorders?

• In addition to providing this training, the company will: (Mention all that
apply)

— Assign strenuous work during cooler parts of the day.

— Give new hires who are not acclimatized lighter work during their first
week.

Rotate workers in strenuous, hot jobs so no one is exposed too long.

— Shield or enclose sources of heat (like furnaces) to minimize radiant heat.

— Provide water-cooled garments or ice-packet vests where necessary.

— Keep first aid supplies and equipment available.
• Workers should:

— Drink a lot of cool water (or an electrolyte solution). You may need a quart
an hour or more, depending on conditions. Drink even if you don’t feel thirsty.

— Take frequent breaks in an air-conditioned or shaded area.

Point out where drinking water and break areas are located on this site:

— Wear appropriate clothing when you’re in the sun. The best clothing is a loose,
lightweight cotton shirt and pants in a light color. Wear a wide-brimmed hat
in the sun.

— Use a sunscreen product to protect your skin from ultraviolet rays in sunlight. It
should have a sun protection factor (SPF) of at least 15. (Check the label.)
— Take frequent cool showers if possible.

— Stay physically fit.

— Limit your use of alcohol. Ask your doctor about prescription drugs you’re
taking.

7. How can we be sure no one on the site is getting affected by the

heat too much?

• Use the buddy system. Watch your co-worker for signs of heat stress.

• Know what to do if you or your co-worker show any symptoms.
