OSHA 10 vs. OSHA 30: Which Training Does Your Crew Need?

When a contractor says a worker needs an “OSHA card,” the next question is often: OSHA 10 or OSHA 30?

The difference isn't simply how many hours someone wants to spend in a classroom. The two courses are designed for workers with different levels of responsibility.

Understanding that distinction can help construction companies put the right employees in the right course, and avoid assuming an OSHA 10- or 30-hour card covers training that must be provided separately for specific workplace hazards.


What is OSHA 10-Hour training?

OSHA's 10-Hour Construction Outreach course is primarily intended for entry-level workers. It introduces common construction safety and health hazards and focuses on recognizing, avoiding, controlling and preventing those hazards.


For many companies, OSHA 10 makes sense for field employees who need a broad foundation in construction safety but do not have significant responsibility for supervising the work of others. Workers who successfully complete the course receive an OSHA 10-hour course completion card.


What is OSHA 30-Hour training?

OSHA 30 goes considerably deeper. OSHA describes the 30-hour course as appropriate for supervisors and workers who have some safety responsibility. It covers a greater variety of subjects and provides more in-depth training than OSHA 10. That can make OSHA 30 a better fit for:

  • Foremen and lead workers

  • Supervisors

  • Superintendents

  • Project managers with field safety responsibilities

  • Employees expected to identify hazards or help enforce safe work practices


The job title isn't really the point. The employee's responsibility is.


A lead worker who regularly directs crews and identifies hazards may benefit more from OSHA 30 than another employee with a management title who rarely works around construction operations.


Does OSHA require OSHA 10 or OSHA 30?

This is one of the most misunderstood parts of Outreach training. Federal OSHA does not generally require workers to complete OSHA 10 or OSHA 30. The OSHA Outreach Training Program is voluntary at the federal level.


However, states, municipalities, employers, unions, general contractors or project owners may require an OSHA Outreach card. Requirements therefore need to be checked for the particular employer, jurisdiction and project. That distinction matters when someone says, “OSHA requires everyone on this project to have an OSHA 10 card.”


The requirement may be very real, but its source may be a project, employer, state or local requirement rather than the federal OSHA Outreach program itself.


Does an OSHA card cover all required safety training?

No.


This may be the most important point for employers.


OSHA 10 and OSHA 30 are hazard-awareness courses. OSHA explicitly states that Outreach courses do not satisfy training requirements contained in specific OSHA standards. A worker may still need additional training based on the hazards and tasks involved in the job.


Depending on the work being performed, that could include subjects such as fall protection, confined spaces, excavation and trenching, hazard communication, lockout/tagout or other applicable requirements. So, an OSHA card should be viewed as part of a company's training program, not the entire program.


Can we just give everyone OSHA 30?

You can choose a higher level of Outreach training for employees when it makes sense, but more hours aren't automatically the best training strategy. For many crews, a better approach is to consider: What does this person actually do?


An entry-level field employee may be well served by OSHA 10 plus the task- and hazard-specific training required for that employee's work. Someone supervising employees, identifying hazards or carrying meaningful safety responsibility may be a stronger candidate for OSHA 30.


The objective isn't simply to accumulate training hours. It is to make sure workers understand the hazards they actually encounter and supervisors have enough depth to recognize and address unsafe conditions.


One more consideration: language

Training only works when workers understand it. OSHA Outreach training can be delivered in languages other than English, including Spanish. For companies with Spanish-speaking crews, bilingual delivery can make the discussion much more useful than treating Spanish as an afterthought. Workers need to be able to ask questions, discuss the conditions they actually see in the field and understand how the material applies to their work.


Not sure which course your team needs?

CDMC Safety provides OSHA Construction Outreach training and other safety training in English and Spanish, with instruction grounded in the work crews actually perform.

If you're trying to determine whether employees need OSHA 10, OSHA 30 or additional hazard-specific training, CDMC Safety can help you evaluate the roles, work and project requirements before scheduling the class.
