Sample STSC item. Pick an answer to see the rationale.
Workers operating jackhammers and pneumatic tools report ringing in their ears at the end of shifts. Sound level monitoring shows sustained exposure at 92 dBA for an 8-hour period. According to OSHA's occupational noise exposure standard (29 CFR 1926.52), what is the required action?
You only get one shot at this sitting.
License renewal, contract requirement, or promotion — whatever brought you to the STSC, the exam fee, the time off work, and the conversation if it goes wrong all add up. CertPrep de-risks the attempt three ways: every question is mapped to BCSP’s published blueprint, four peer-reviewed learning-science methods sit under every session, and a readiness score tells you when you’re actually set to sit.
