Question 1. What is OSHA’s position on computer-based training programs for cognitive training?

Answer: In OSHA’s view, self-paced, interactive computer-based training can serve as a valuable training tool in the context of an overall training program. However, use of computer-based training by itself would not be sufficient to meet the intent of most of OSHA’s training requirements, in particular those of HAZWOPER. Our position on this matter is essentially the same as our policy on the use of training videos, since the two approaches have similar shortcomings. OSHA urges employers to be wary of relying solely on generic, “packaged” training programs in meeting their training requirements. For example, training under HAZWOPER includes site-specific elements and should also, to some degree, be tailored to workers’ assigned duties.

Interpretation letters of OSHA, (from J. H. Ward, November 22, 1994), https://www.osha.gov/laws-regs/standardinterpretations/1994-11-22
