In California, a serious Respiratory Protection violation carries a maximum penalty of $25,000 per violation in 2026, rising to $162,851 for a willful or repeat violation. Respiratory Protection is enforced for private construction employers by Cal/OSHA (Division of Occupational Safety and Health), under 8 CCR §5144, with §5141.1 for wildfire smoke rather than 29 CFR 1910.134. California sets its own maximums, above the federal amount for serious violations and below it for willful and repeat violations.

What California's own rule says
“Where the current AQI for PM2.5 is equal to or greater than 151, but does not exceed 500, the employer shall provide a sufficient number of respirators to all employees for voluntary use in accordance with section 5144 and encourage employees to use respirators.”
Section 5144 restates the federal respiratory protection duties in California's numbering. What has no federal counterpart is the rule sitting next to it: §5141.1 makes respirators an outdoor-air-quality obligation. Once the current AQI for PM2.5 reaches 151 and wildfire smoke is reasonably anticipated, employers must supply NIOSH-approved respirators such as N95s for voluntary use and encourage their use; above an AQI of 500 respirator use becomes mandatory under §5144, with an assigned protection factor high enough to bring the air inside the facepiece below 151. Training for the voluntary tier uses Appendix B to §5141.1 rather than Appendix D to §5144. For outdoor construction in California this converts a respiratory program from a chemical-exposure question into a seasonal one.

How California Enforces Respiratory Protection
California runs an OSHA-approved State Plan administered by Cal/OSHA (Division of Occupational Safety and Health), which covers private-sector construction. Its compliance officers enforce California's own standards, which must be at least as effective as federal OSHA's and may go further. On this subject the rule is 8 CCR §5144, with §5141.1 for wildfire smoke, which differs from the federal text (see the state rule above). California also sets its own civil-penalty maximums, above the federal amount for serious violations and below it for willful and repeat violations (see the penalty table below).
A single inspection can produce several per-instance citations. Recurring self-audits against 8 CCR §5144, with §5141.1 for wildfire smoke, before an officer arrives, are the most reliable defense.

Free, confidential help: OSHA On-Site Consultation
In California, the program is CAL/OSHA Consultation Services Branch (Department of Industrial Relations). OSHA describes it as “Primarily for smaller businesses, no-cost, confidential consultations help employers identify and address hazards and establish or improve safety and health programs.” It is separate from OSHA enforcement; the employer commits to correcting serious hazards.

OSHA describes it this way: "Primarily for smaller businesses, no-cost, confidential consultations help employers identify and address hazards and establish or improve safety and health programs." Consultations are separate from OSHA enforcement, and the employer commits to correcting serious hazards.
