All of the following risk factors can affect a worker’s heat tolerance, except:

Not drinking enough fluids

Physical condition

Hair color

Age

Health conditions that can increase a worker’s risk of heat illness include:

When workers sweat, their bodies lose some of the water and electrolytes they need to function properly. Workers can help replace water and electrolytes by doing the following except:

Consuming sports drinks

Drinking plenty of water

Eating regular meals and salty snacks

Exercising often

According to NIOSH, how much water should a worker drink when engaged in moderate activity in moderate weather conditions?

One cup every two hours

One cup per hour

One cup every 15 to 20 minutes

One to two cups per day

To stay properly hydrated, remind workers it is best to drink water frequently:

Whenever they feel light-headed

Before they feel thirsty

Before and after their shift

None of the above

Acclimatization:

Happens when a worker is exposed to extreme temperatures for 7-10 days

Will not protect workers right away when a heat wave strikes

Is usually maintained even when a worker is not exposed to the extreme temperatures for a few days

All of the above

All of the following statements about salt tablets are true, EXCEPT:

Salt tablets are a useful supplement for replacing electrolytes when working hard in hot temperatures

Salt tablets should only be used when recommended by a physician

If too many are taken, can result in increased dehydration

Are usually unnecessary, since drinking plenty of water and eating regular meals and snacks can help workers replace electrolytes

During heat waves, workers:

Will need to take the day off

Should wear a few extra layers of clothing to shield them from the heat

Will need to take breaks more frequently

Should wear dark colors

Reduce heat illness by doing all of the following EXCEPT:

Making workers aware of the risk factors that play a role in heat illness

Keeping workers out of air conditioning, which can ruin acclimatization

Encouraging workers to stay hydrated by keeping drink coolers, cups, and accessories nearby

Providing heat relief clothing and accessories like cooling vests

If a worker has heat stroke:

He or she might still sweat

He or she may experience high body temperatures, seizures, confusion, or loss of consciousness

You should immediately call 9-1-1 and attempt to cool the person down
