OSHA 10/30

What It Means for Trade Workers

OSHA 10 and OSHA 30 are safety training courses developed by the Occupational Safety and Health Administration to educate workers and supervisors on recognizing and preventing workplace hazards. The OSHA 10-hour course is designed for entry-level workers and covers fundamental safety topics including fall protection, electrical safety, personal protective equipment, hazard communication, scaffolding safety, and workers rights under OSHA regulations. The OSHA 30-hour course is intended for supervisors, foremen, and safety personnel and provides deeper coverage of the same topics plus additional modules on excavation, crane safety, confined spaces, and safety management systems. Both courses are delivered by OSHA-authorized trainers and result in a Department of Labor completion card. While OSHA 10 and 30 are technically voluntary at the federal level, many states, cities, and project owners require one or both as a condition of working on construction sites. New York City, for example, requires OSHA 30 for all construction workers on sites requiring a Site Safety Plan. Many union apprenticeship programs include OSHA 10 or 30 as part of their curriculum. General contractors frequently require subcontractor employees to hold current OSHA cards before being allowed on site. Holding an OSHA 30 card demonstrates a commitment to safety that can enhance a tradesperson employability and is increasingly a baseline requirement across the industry.
