CPA Health Assessment & First Aid 2

Question 1

A worker is exposed to hydrogen sulfide (H2S) and collapses. What is your FIRST action before providing aid?

Accepted Answer

Don appropriate respiratory protection before entering the area

Answer

Rescuers must never enter an H2S atmosphere without proper SCBA or supplied-air respirator, or they risk becoming victims themselves.

Question 2

Which symptom is the EARLIEST warning sign of H2S overexposure at low concentrations?

Accepted Answer

Olfactory fatigue (loss of smell)

Answer

H2S quickly deadens the sense of smell, so a worker may no longer detect the gas while still being exposed to dangerous levels.

Question 3

A petroleum worker receives a chemical splash of crude oil distillate to the eyes. The correct first aid is to:

Accepted Answer

Flush the eyes with large amounts of water for at least 15 minutes

Answer

Continuous flushing with water for a minimum of 15 minutes dilutes and removes chemical contaminants from the eyes.

Question 4

When treating a worker with a chemical burn from a petroleum solvent on the skin, you should:

Accepted Answer

Remove contaminated clothing and flush the area with water for 15–20 minutes

Answer

Removing clothing and flushing with water dilutes and washes away the chemical, limiting tissue damage.

Question 5

A coworker inhales hydrocarbon vapors and becomes dizzy and confused. After calling for help, you should:

Accepted Answer

Move the victim to fresh air and monitor breathing

Answer

Fresh air removes the victim from the exposure source and allows the body to begin clearing inhaled vapors while you monitor for deterioration.
