Rationale: SCBA or equivalent required.
Q23: SCBA stands for:
A: Self-Contained Breathing Apparatus
Rationale: Independent air supply.
Q24: A respirator fit test must be:
A: Conducted before initial use
Rationale: Ensures proper seal and protection.
Q25: PPE must be:
A: Inspected before use
Rationale: Detects damage and maintains efficacy.
Q26: Chemical-resistant gloves are chosen based on:
A: Chemical breakthrough data
Rationale: Protects against specific toxins.
Q27: Eye protection is required when:
A: Splashes or particles are a hazard
Rationale: Prevents eye injury.
Q28: Hearing protection is required when noise exceeds:
A: 85 dBA
Rationale: OSHA hearing conservation threshold.
Q29: Respiratory cartridges must be changed when:
A: End of service life or breakthrough evidence
Rationale: Ensures contaminated air is not inhaled.
