Safety Trained Supervisor in Construction (STSC) Practice Exam

Which scenario does NOT require employers to train employees on hazardous chemicals?

1. Initial introduction of a new chemical

2. Resupply of chemicals

3. Change in chemical handling procedures

4. Emergency response training for spills

The correct answer is: Resupply of chemicals

The scenario regarding the resupply of chemicals does not require specific training for employees on hazardous chemicals. When there is a resupply of chemicals that have already been introduced and for which employees have already received training, no additional training is required on those specific chemicals, as long as the safety data sheets and handling procedures remain unchanged. In contrast, the initial introduction of a new chemical necessitates training to ensure employees understand the hazards and safe handling practices associated with the new substance. Similarly, any change in chemical handling procedures would require retraining to inform employees of the new risks and safety measures. Emergency response training for spills is equally essential, as it prepares employees to effectively and safely manage any hazardous situations that may arise.
