OSHA 10 offers a basic overview, while OSHA 30 provides more advanced and detailed training.
OSHA 10-Hour Training is designed for entry-level workers. This course covers the basics of workplace safety and is commonly taken by new employees or laborers in construction or general industry roles.
OSHA 30-Hour Training is for workers with safety responsibilities, such as supervisors, team leaders, and site managers. It includes more topics and provides detailed guidance on hazard control, safety planning, and OSHA standards.
