Certifications (Industrial): OSHA 30 Hour Safety

About OSHA

The Occupational Safety and Health Administration (OSHA) is an agency of the United States Department of Labor established in 1970. Its mission is to assure safe and healthful working conditions for working men and women by establishing and enforcing standards and by providing training, outreach, education and assistance. The Occupational Safety and Health Administration agency covers most private sector employers and their workers. Some public sector employers and workers in the 50 states and certain territories and jurisdictions also fall under the federal authority of OSHA. Military, state, and local governments, and tribes, must comply with their own programs meeting equivalent OSHA standards.

The Occupational Safety and Health Administration (OSHA) Outreach Training Program provides workers with basic and advanced training about common safety and health hazards on the job. Outreach training emphasizes hazard identification, avoidance, control and prevention, not OSHA standards.


The 30-hour training program is intended for workers with some safety responsibility who would benefit from a greater depth and variety of training than the 10-hour training. All outreach training is intended to cover an overview of the hazards a worker may encounter on a job site. Training emphasizes hazard identification, avoidance, control and prevention.

OSHA 30-Hour training is a voluntary safety program. Students who successfully complete the OSHA 30-Hour General Industry course receive an OSHA 30-Hour General Industry wallet card as proof of completion. 

  • Training must be delivered by Authorized Trainer of the OSHA Training Institute Education Center.
  • Training is limited to a maximum of 7.5 student contact hours conducted per calendar day. Therefore the 30-hour classes must take a minimum of four (4) calendar days.

The OSHA 30-Hours voluntary training is for persons with some safety responsibility.   Before engaging in any potentially hazardous activities, workers must receive appropriate safety training from their employer, as defined in OSHA standards.  

This training demonstrates you are developing a safety mindset and have learned valuable work skills.  At the completion of this training you will know your rights as a worker, employer responsibilities, and how to file a complaint.  The knowledge and skills obtained through this program make a worker more employable with a competitive advantage in the job market.

Between FY 2012 and FY 2016, more than 3.94 million workers were trained in job hazard recognition and avoidance through the program.
