Cal/OSHA vs. Federal OSHA: Aerial Lift and MEWP Certification Requirements
Understanding the differences between Federal OSHA and Cal/OSHA is essential for employers and safety professionals working with mobile elevated work platforms (MEWPs) including boom lifts, scissor lifts, and cherry pickers. While both agencies aim to ensure workplace safety, Cal/OSHA often enforces stricter and more detailed regulations than the federal baseline. If your organization operates in California, failing to comply can lead to significant fines and enforcement actions.
What Is Federal OSHA and How Does Cal/OSHA Differ?
The Occupational Safety and Health Administration (OSHA) is the federal agency responsible for setting and enforcing safety standards in workplaces across the United States. OSHA provides training, outreach, education, and assistance to help employers ensure a safe working environment.
Cal/OSHA, or the California Division of Occupational Safety and Health, is one of 22 states that operate an OSHA-approved state plan. These plans must be at least as effective as federal standards—but California often goes further, requiring more stringent safety practices and documentation.
Tip: If your business operates in California, Cal/OSHA requirements apply and take precedence wherever they are more stringent than federal OSHA.
Regulatory Scope: Who Regulates What?
- Federal OSHA applies nationwide and sets the minimum legal safety standards.
- State Plans (like Cal/OSHA) can impose additional, stricter rules.
- California’s plan specifically regulates most private and public sector workplaces within the state.

- Applicable Equipment: Boom lifts, scissor lifts, aerial ladders, etc.
- Key Requirements:
- Fall protection (body belt + lanyard) on boom lifts
- Solid standing in basket
- Controls testing
- No formal "certification," but training is mandatory
Cal/OSHA (GISO §3648)
- Mandatory Fall Protection:
- Body harness with personal fall arrest system (boom-type lifts)
- Strong recommendation for scissor lifts
- Training Documentation: Must be kept on file
- Equipment Classification: More detailed than federal definitions (§3638)
Aerial Lift Safety Rules: Federal OSHA vs. Cal/OSHA
Fall Protection (Boom Lifts)
- Federal OSHA: Required
- Cal/OSHA: Required
Fall Protection (Scissor Lifts)
- Federal OSHA: Not explicitly required
- Cal/OSHA: Strongly recommended
Training Documentation
- Federal OSHA: General requirement
- Cal/OSHA: Specific and detailed documentation required
Lift Classification
- Federal OSHA: Broad definitions
Cal/OSHA: More specific and varied
Penalties and Enforcement Actions
Cal/OSHA is known for thorough inspections and stricter enforcement. Its penalties for noncompliance are often higher and more precise than Federal OSHA’s.
Cal/OSHA Penalties (as of Jan 2025):
- General violations: Up to $16,285
- Serious violations: Up to $25,000

What Employers Should Do
- Know the Differences: Familiarize yourself with both OSHA and Cal/OSHA requirements, especially if you operate in California.
- Keep Thorough Records: Document who was trained, when, and by whom—especially for aerial lift operators.
- Follow ANSI Guidance: Though voluntary, ANSI standards like ANSI/ASSP Z359.2 are widely recognized and often used as best practices for fall protection, even if not required by law.
Bottom Line: Proactive safety training, clear documentation, and routine evaluations are the best defense against injuries—and penalties.
Takeaways
- Cal/OSHA requirements exceed Federal OSHA in areas like evaluation frequency, record keeping, and fall protection.
- Employers must stay informed and adopt stronger safety practices where state rules apply.
- Fines can range from $300 to over $160,000 for noncompliance—prevention pays.
