Overview of Cal-OSHA

The California Division of Occupational Safety and Health, or Cal/OSHA, is a California state department that protects workers from health and safety hazards on the job in most workplaces in California. As it relates to industrial fixed equipment mechanical integrity, Cal/OSHA oversees programs promoting the safe use of pressure vessels (e.g., boilers and tanks). Cal/OSHA is permitted to conduct inspections of California workplaces for any number of reasons, including:

  • If they receive a report of an industrial accident occurring in a workplace,
  • If they receive a complaint  about an occupational or workplace safety hazard in a workplace, or
  • As a part of a regular inspection program dealing with any industries that happen to have a high rate of occupational hazards, deaths, injuries, or illnesses.

Cal/OSHA also maintains a large number of standards and regulations to protect the health and safety. These cover a range of topics as diverse as access to work locations, boilers and pressure vessels, materials, and pipelines.
