Heat Stress Quiz: Heat Exhaustion and Heatstroke

Question 1

Which combination best describes workplace heat-stress risk?

Environmental heat, workload, clothing, and individual factors

Answer

Air temperature alone in every situation

Answer

Only whether work is outdoors

Answer

Only the number of hours since breakfast

Question 2

Can workers develop heat illness indoors?

Accepted Answer

Yes, particularly near hot processes or in poorly controlled hot environments

Answer

No, because sunlight is required

Answer

No, if there are walls around the job

Answer

Only if a window is open

Question 3

What does acclimatization mean in occupational heat guidance?

Accepted Answer

Gradual physiological adaptation to repeated heat exposure

Answer

Drinking all daily water before starting work

Answer

Wearing more layers to sweat faster

Answer

Working a full hot shift on the first day

Question 4

A new worker starts a physically demanding job in hot conditions. What is appropriate?

Accepted Answer

A gradual exposure schedule with close supervision and heat controls

Answer

A full workload immediately to test endurance

Answer

No rest until the worker asks twice

Answer

Using only the experienced workers' pace as a requirement

Question 5

Why should a returning worker's heat exposure be reviewed after time away?

Accepted Answer

Acclimatization can be reduced during absence from heat

Answer

A previous hot-weather job guarantees permanent adaptation

Answer

Time away always increases heat tolerance

Answer

Only newly recruited workers can become ill

Question 6

Which is an engineering control for radiant heat?

Accepted Answer

A suitably designed heat-reflective shield between source and worker

Answer

A reminder to finish faster

Answer

A longer timesheet

Answer

A rule forbidding symptom reports

Question 7

Which measure primarily changes work organization to reduce heat exposure?

Accepted Answer

Schedule heavy work for cooler periods with appropriate recovery breaks

Answer

Paint the tools a brighter colour

Answer

Move drinking water farther away

Answer

Ask workers to ignore discomfort

Question 8

Why should drinking water be readily accessible near hot work areas?

Accepted Answer

Workers need practical opportunities for frequent appropriate hydration

Answer

Water is useful only after an emergency

Answer

A distant water point always ensures adequate intake

Answer

Thirst always warns early enough to prevent dehydration

Question 9

A worker plans to drink an extreme volume of water at once to avoid breaks. What is the best advice?

Accepted Answer

Use regular appropriate intake and planned breaks rather than forced excessive drinking

Answer

Drink the maximum possible amount immediately

Answer

Avoid all fluids for the rest of the shift

Answer

Replace every drink with alcohol

Question 10

Does removing required protective clothing without assessment provide an acceptable heat-control plan?

Accepted Answer

No; manage heat while maintaining protection against the task's other hazards

Answer

Yes, because heat always cancels other risks

Answer

Yes, whenever clothing feels uncomfortable

Answer

Yes, if no supervisor is nearby

Question 11

A worker in heat becomes confused and has slurred speech. What should coworkers do?

Accepted Answer

Treat it as an emergency, call local emergency services, and begin rapid cooling

Answer

Wait until the worker's skin becomes dry

Answer

Tell the worker to finish the task first

Answer

Give instructions to walk alone to the car park

Question 12

Does continued sweating rule out heatstroke?

Accepted Answer

No; heatstroke can occur with profuse sweating

Answer

Yes, heatstroke always means completely dry skin

Answer

Yes, if the worker can hold a tool

Answer

Yes, if the worker has drunk water

Question 13

While emergency help is being called for suspected heatstroke, what should others do?

Accepted Answer

Move the person to a cool place if safe and start rapid effective cooling

Answer

Cover the person in heavy insulating blankets

Answer

Wait for a temperature reading before doing anything

Answer

Leave the person alone to rest

Question 14

A heat-affected worker is unconscious. Should you give them a drink?

Accepted Answer

No; activate emergency care and protect the airway while following first-aid instructions

Answer

Yes, pour water into the mouth

Answer

Yes, if the drink contains electrolytes

Answer

Yes, if the water is very cold

Question 15

Which symptoms can be consistent with heat exhaustion?

Accepted Answer

Headache, nausea, weakness, dizziness, and heavy sweating

Answer

Improved concentration and increased coordination

Answer

Absence of any fatigue after exertion

Answer

A guaranteed absence of thirst

Question 16

A worker with possible heat exhaustion is alert and can swallow. What is appropriate while arranging medical evaluation?

Accepted Answer

Stop work, move to a cool area, provide cooling, and offer frequent sips of water

Answer

Keep the worker on the task to maintain circulation

Answer

Give alcohol to relax the worker

Answer

Send the worker to rest alone in direct sun

Question 17

Why is a buddy system useful during hot work?

Accepted Answer

Coworkers may recognize concerning changes in one another and summon help

Answer

It makes water and breaks unnecessary

Answer

It prevents every heat illness automatically

Answer

It allows the supervisor to stop all monitoring

Question 18

A hot-weather worker has severe muscle pain and dark, cola-coloured urine after heavy exertion. What is needed?

Accepted Answer

Stop activity and seek urgent medical assessment

Answer

Assume ordinary muscle soreness and continue

Answer

Delay reporting until the next week

Answer

Treat the urine colour as proof of good hydration

Question 19

What should determine heat-related work and recovery arrangements?

Accepted Answer

Assessed heat exposure, workload, clothing, acclimatization, and worker needs

Answer

One fixed break schedule for every job and climate

Answer

Only the calendar month

Answer

Only whether work is classed as skilled

Question 20

Why can high humidity make hot conditions harder to tolerate?

Accepted Answer

It can reduce the effectiveness of sweat evaporation

Answer

It always lowers body temperature

Answer

It removes the need for cooling

Answer

It prevents sweating entirely in every person

Question 21

Can some health conditions or medicines affect heat tolerance?

Accepted Answer

Yes; workers may need confidential occupational-health or medical advice

Answer

No, individual factors never affect heat risk

Answer

Only a worker's height matters

Answer

Only nonprescription medicines can matter

Question 22

What should workers do when they notice early heat-illness symptoms?

Accepted Answer

Report promptly and act under the heat-response plan

Answer

Hide them until a productivity target is reached

Answer

Wait for a coworker to collapse first

Answer

Assume symptoms prove they are unfit for every job

Question 23

Where should recovery breaks occur where practicable?

Accepted Answer

In an accessible cool or shaded location suited to recovery

Answer

Beside the same radiant heat source

Answer

Inside an unventilated parked vehicle

Answer

Only in the noisiest part of the work area

Question 24

A heatwave is forecast for a physically demanding job. What should management do?

Accepted Answer

Review controls, staffing, timing, acclimatization, and emergency readiness before work

Answer

Wait for the first medical incident

Answer

Issue the same plan without checking changed conditions

Answer

Cancel water deliveries to reduce carrying

Question 25

Which feature makes a heat-emergency plan practical?

Accepted Answer

Answer

Only a generic warning poster

Answer

Only the temperature from last summer

Answer

Only an instruction to drink more water
