OSHA HazCom / GHS Exam Questions & Answers 2026 (11–20)

Question 1

How many hazard pictograms are defined in the GHS system?

TheoryPractice · Accepted Answer

Nine. GHS defines nine pictograms: Health Hazard, Flame, Exclamation Mark, Gas Cylinder, Corrosion, Exploding Bomb, Flame Over Circle, Skull and Crossbones, and Environment.

Question 2

Which GHS pictogram is NOT mandatory on labels under OSHA's Hazard Communication Standard?

TheoryPractice · Accepted Answer

Environment (aquatic toxicity). OSHA does not regulate environmental hazards, so the Environment pictogram is not required on HazCom labels, although suppliers may include it.

Question 3

A chemical that can cause cancer should carry which pictogram?

TheoryPractice · Accepted Answer

Health Hazard (silhouette). Carcinogenicity is a serious health endpoint assigned the Health Hazard silhouette pictogram, not the Exclamation Mark.

Question 4

A spray paint can labeled flammable would most likely display which pictogram?

TheoryPractice · Accepted Answer

Flame. Flammable aerosols and liquids use the Flame pictogram.

Question 5

TheoryPractice · Accepted Answer

Corrosion. Substances causing serious eye damage or skin corrosion use the Corrosion pictogram.

Question 6

Which pictogram appears on a propane or compressed-air cylinder?

TheoryPractice · Accepted Answer

Gas Cylinder. Gases under pressure carry the Gas Cylinder pictogram (propane would also carry the Flame pictogram because it is flammable).

Question 7

What does a black symbol inside the red diamond always sit on?

TheoryPractice · Accepted Answer

A white background. GHS pictograms always use a black symbol on a white background framed by the red diamond border.

Question 8

If a chemical is both flammable and acutely toxic, how are pictograms shown?
