✍️ Sample CET Questions & Answers
1. When developing a written exam to evaluate trainee performance after a safety course, a CET should ensure the questions have content validity. What does this mean?
Content validity ensures that an exam accurately measures a trainee's performance on job-relevant knowledge and skills that were covered in the training. The evaluation instrument must align directly with the learning objectives and the actual requirements of the job to be considered valid.
2. Employers with 10 or fewer employees at all times during the previous calendar year are generally:
OSHA's recordkeeping rule partially exempts employers who had 10 or fewer employees during the entire previous calendar year from routine injury and illness recordkeeping, though they must still report severe injuries.
3. What is the purpose of the 'hot zone' designation at a HAZMAT incident?
The hot zone is the area of actual or potential contamination where entry is restricted to properly protected emergency responders.
4. Under OSHA's Permit-Required Confined Space standard (29 CFR 1910.146), the entry permit must be retained for at least:
OSHA requires that canceled confined-space entry permits be retained for at least one year after the permit's expiration so employers can review any problems that arose during entry.
5. A precautionary statement on a GHS label serves what primary purpose?
Precautionary statements describe recommended measures to minimize or prevent adverse effects from exposure to a hazardous product.
6. A CET is evaluating a fall protection training program. Which method would be most effective for assessing Level 3 (Behavior) of the Kirkpatrick Model?
Level 3 of the Kirkpatrick Model evaluates the extent to which participants apply what they learned back on the job (behavior change). Direct observation of work practices is the most effective way to assess this transfer of skills and knowledge to the workplace. Surveys assess reaction (Level 1), exams assess learning (Level 2), and injury rates assess results (Level 4).
