What Is The Difference Between OSHA 10 and 30?

Could a single safety mistake cost someone’s life? Sadly, yes. A scaffolding accident in Sabine Pass, Texas, is one recent instance. According to the Carabin Shaw news, the accident occurred on the 29th of April, 2025, and resulted in the death of three workers and two injuries. They fell from almost 85 feet.  The location was closed down right away, and OSHA initiated an investigation. 

In 2023, 5,283 workers were killed on the job, according to the Bureau of Labor Statistics. That's where OSHA training comes in. If you are in the construction, manufacturing, or any other high-risk sector, you're familiar with OSHA 10 and OSHA 30. But what exactly is the difference between OSHA 10 and OSHA 30? And how do you know you need to get either of them? Scroll down to learn all about OSHA 10 vs 30.

What Is OSHA 10?

OSHA 10 is a basic safety training program that familiarizes workers with key workplace safety concerns. It's designed for new employees or those new to a high-hazard industry like construction, manufacturing, or general industry work. The training itself typically takes 10 hours and involves the fundamentals of hazard recognition, safety protocol, and prevention of injury. The topics usually cover anything from fall protection, electrical safety, personal protective equipment (PPE), to emergency response.

The goal of OSHA 10 is to give you enough knowledge to recognize common hazards and avoid on-site accidents. As it is shorter and focuses more on general awareness of safety, OSHA 10 is generally required for employees who have no supervisory roles but need to acquire a general understanding of jobsite safety.

What Is OSHA 30?

OSHA 30 is a more comprehensive safety training course, designed for supervisors, managers, and the more responsible employees on site. It addresses workplace hazards and safety regulations more thoroughly, preparing participants to not only protect themselves but also oversee the safety of others. This training usually takes 30 hours to complete and covers all the topics of OSHA 10, plus others like advanced fall protection, hazard communication, electrical safety, and how to operate safety programs.

OSHA 30 provides extensive training on recognizing advanced risks, applying safety standards, and following OSHA compliance. It's ideal for individuals in management roles who must ensure that their employees work safely and comply with safety standards as per law. For example, supervisors, foremen, and safety officers for construction and general industry environments.
