When is unaccredited in-house training allowed?

• A. Maintenance or custodial working in areas where friable ACM is present (2 hour awareness course)
• B. Both A and B
• C. Never allowed
• D. Maintenance personnel disturbing small amounts of asbestos (2 hours awareness + 14 for sixteen hours operations and maintenance training)

Answer: (B)

Unaccredited in-house training is allowed in two specific, low-risk scenarios to ensure workers understand asbestos hazards and safe practices without requiring external accreditation.

First, maintenance or custodial workers who will operate in areas where friable asbestos-containing material is present can take a short 2-hour awareness course. This focuses on recognizing asbestos-containing materials and basic precautions, which is appropriate when the work does not involve disturbing asbestos.

Second, maintenance personnel who will disturb small amounts of asbestos must receive more training: a 2-hour awareness course plus an additional 14 hours of operations and maintenance training, totaling 16 hours. This provides the necessary depth on control measures, safe work practices, and procedures for working around asbestos.

Together, these two pathways cover both the low-risk awareness need and the more comprehensive training required for limited disturbance, which is why both scenarios are allowed. The other options miss one of these valid pathways or incorrectly state that training is never allowed.
