CHRA Quiz

What is the main purpose of CHRA?

• Protect employee health from hazardous chemicals

• List all workplace chemicals

• Find cheaper chemicals

• Meet trade regulations

A worker is exposed to a chemical when it might be:

• Breathed in, on skin/eyes, or swallowed

• Stored in the same room

• Listed in the inventory

• Transported nearby

For route of exposure through inhalation, what scale is used to indicate the degree of hazard?

• A scale of A to E

• A scale of 1 to 3

• A scale of 1 to 5

• A scale of 1 to 10

A Hazard Rating (HR) of 5 means:

• Minimal health effects

• Moderate risk

• Most severe health effects

• No significant hazard

Dermal exposure is categorized by:

• Corrosion and irritation only

• Sensitization only

• Irritation, corrosion, sensitization, and absorption

• Acute toxicity only

If exposure route isn't specified, assume:

• Safe for all routes

• Inhalation only

• All routes apply (inhalation, skin, ingestion)

• More testing needed

What does HR stand for in CHRA?

• Human Resources

• Hazard Reaction

• Hazard Rating

• Health Response

First step in conducting CHRA is:

• Evaluate control measures

• Gather information

• Determine risk level

• Prepare report

Which is NOT a CHRA objective?

• Find cheapest chemicals

• Recommend control measures

Where can you find hazard information?

• Internet research only

• SDS, labels, waste cards

• Manufacturer website only

• Laboratory testing only
