Becoming an Authorized Construction Trainer. To become an authorized trainer, a
person must meet the following two prerequisites which consist of a training and
experience component:
1. Five years of construction safety experience. A college degree in occupational
safety and health, a Certified Safety Professional (CSP), or Certified Industrial
Hygienist (CIH) designation, in the applicable training area may be substituted for
a total of two years of experience); and
2. Completion of OSHA course #510 Occupational Safety and Health Standards for
the Construction Industry. Please note that the 30-hour Construction outreach
class is not considered equivalent to course #510. The 30-hour Construction
outreach class is a hazards-based class, which is delivered by OSHA authorized
trainers. The OSHA #510 course covers OSHA standards and is only offered
through the OSHA Training Institute (OTI) or its OTI Education Centers.
Experience cannot be substituted for the training prerequisite component. OSHA does
not issue waivers for these prerequisites. After satisfying the prerequisites, a person must
complete course #500 Trainer Course in Occupational Safety and Health Standards for
the Construction Industry. This course includes knowledge and performance-based tests.
Trainers must pass both of these tests to become an authorized trainer.

Ask your OSHA 10 instructor if they followed these procedures to help determine if they
are legitimate instructors.  YOU MAY BE SURPRISED.
