CSO Chemical Safety and GHS Hazard Communication 2 — Questions and Answers
Question 1: What is the correct first aid for a chemical splash to the eyes?
- Flush with clean water for 15–20 minutes (Correct answer)
- Apply a sterile eye patch
- Use neutralizing eye drops
- Rub the eyes gently to remove the chemical
Correct answer: Flush with clean water for 15–20 minutes
Immediately flushing the eye with clean water for 15–20 minutes dilutes and removes the chemical to minimize injury.
Question 2: Which GHS label element — 'Danger' or 'Warning' — indicates a more severe chemical hazard?
- Danger (Correct answer)
- Warning
- Caution
- Notice
Correct answer: Danger
'Danger' is the signal word used for chemicals with more severe hazards, while 'Warning' is used for less severe hazards.
Question 3: Where must Safety Data Sheets be stored to comply with OSHA requirements?
- Readily accessible to all employees in the work area (Correct answer)
- Only in the supervisor's locked office
- In a secured safety cabinet
- Posted on the main bulletin board only
Correct answer: Readily accessible to all employees in the work area
OSHA requires SDSs to be readily accessible to employees at all times during their work shifts in areas where hazardous chemicals are present.
Question 4: What PPE is typically required when handling corrosive chemicals?
- Chemical-resistant gloves and eye protection (Correct answer)
- Standard leather work gloves only
- Hard hat and steel-toed boots only
- Hearing protection and face shield only
Correct answer: Chemical-resistant gloves and eye protection
Corrosive chemicals require chemical-resistant gloves and splash-proof eye/face protection to prevent burns to skin and eyes.
Question 5: Which GHS pictogram represents an oxidizing chemical hazard?
- Flame over a circle (Correct answer)
- Exclamation mark
- Health hazard (silhouette)
- Skull and crossbones
Correct answer: Flame over a circle
The flame-over-circle pictogram identifies oxidizing chemicals that can intensify fires by releasing oxygen when heated or in contact with other materials.
Question 6: What does 'flash point' mean for a flammable liquid?
- The lowest temperature at which vapors can ignite (Correct answer)
- The boiling point of the chemical
- The maximum recommended storage temperature
- The temperature at which the chemical self-ignites
Correct answer: The lowest temperature at which vapors can ignite
Flash point is the minimum temperature at which a liquid produces enough vapor to briefly ignite when exposed to an ignition source.
