Training, Education and Communication
Design and delivery
Training is a control of last resort in the hierarchy - it does not substitute for engineering out a hazard, and cutting a training class does not reduce a noise or chemical exposure. Good programs follow an instructional design cycle (ADDIE: analyze, design, develop, implement, evaluate). Analysis identifies the audience, the tasks, and the gap between current and required competence. Objectives should be written as observable, measurable behaviors tied to Bloom's levels - knowledge, comprehension, application, analysis, evaluation, creation - because you can test application but not attitude.
Adult learning principles (Knowles) matter in exam scenarios: adults need relevance, bring experience, prefer problem-centered over subject-centered content, and require respect and self-direction. Practical hooks: short sessions, hands-on practice, and content in the learner's language and literacy level.
Regulatory anchors include hazard communication training under 29 CFR 1910.1200 (must be understandable, cover hazards, protective measures, and the written program), respirator training and fit testing before use, and lockout/tagout authorized-employee training. Retraining is triggered by a change in the workplace or procedures, evidence that the employee lacks the required knowledge, or an evaluation showing the training was ineffective.
Evaluating training
Kirkpatrick's four levels: 1 reaction, 2 learning, 3 behavior on the job, 4 results (incident rates, quality, cost). Only Level 3 and 4 evidence speaks to whether the training reduced risk.
Traps
- Citing Level 1 reaction scores as proof of effectiveness.
- Assuming a signed attendance sheet demonstrates competence.
- Using training to satisfy a hazard that requires a guard or ventilation.
- Ignoring literacy, language, or shift-access barriers.
Worked example
A crew still has hand injuries after a glove-training class. Level 1 evaluations were excellent and Level 2 scores were high - but observation (Level 3) shows workers removing gloves because they interfere with a pinch point. The correct response is a tool or fixture change, not another class.
Rule of thumb
If you cannot observe it, you cannot certify it.
