A copy of the ERG's nine classes and their dangers is made available to all staff.

• A. False
• B. True
• C. Only to supervisors
• D. Only in emergency

Answer: (B)

Having hazard information accessible to all staff is essential. The ERG groups hazardous materials into nine classes and explains the dangers, typical health and safety risks, and basic response actions for each class. If every staff member has a copy, they can quickly identify what they might be dealing with during any incident—spill, exposure, or a misused chemical—and know the appropriate precautions, PPE, and immediate steps to take. This preparedness helps staff act safely right away, reduces confusion, and supports consistent training across the team. Restricting access to supervisors or reserving it only for emergencies would leave others unprepared, potentially delaying a safe, effective response. So, making the ERG’s nine classes and their dangers available to all staff is the best approach.
