OSHA does not require anyone to complete the OSHA 10-hour or 30-hour Outreach Training courses. However, some states and municipalities have made the classes mandatory for certain workers in the construction industry. Also, some employers, unions, organizations or other jurisdictions may also require this training.

The 10-hour outreach courses provide basic awareness training on the recognition, avoidance, abatement, and prevention of workplace hazards within the construction industry.

The 30-hour outreach courses provide a greater depth and variety of training on an expanded list of topics associated with workplace hazards in the construction industry. This course is designed for supervisors and project managers.

OSHA recommends outreach courses as an orientation to occupational safety and health for workers. However, some states have enacted laws mandating the training. (see chart below)
