Cal/OSHA First Aid & CPR Requirements for Construction: California-Specific Guide

In California, federal OSHA is the floor — not the ceiling. Construction first aid in California is governed by Cal/OSHA Title 8 §1512, which requires a suitable number of appropriately trained persons, a weatherproof first aid kit stocked to the section's table or a licensed physician's list, posted emergency numbers and transport arrangements, and a written emergency medical services plan. It sits beside California's mandatory written IIPP (§3203) and Heat Illness Prevention Standard (§3395). The penalties are higher than federal too: a serious violation runs up to $25,000 and a willful/repeat up to $162,851, and a willful violation causing death can trigger criminal charges under Labor Code §6425.

Why California Is Different

If you manage construction safety in California, you operate under Cal/OSHA — the Division of Occupational Safety and Health (DOSH). California runs one of the 22 State Plans that cover both private-sector and public-sector workers (29 CFR 1952.7), a program federal rules require to be at least as effective as federal OSHA in its standards and its enforcement (29 CFR 1902.3(c)(1) and (d)(1)). On first aid, California goes further:

• A higher serious-penalty cap: $25,000 under Title 8 §336(c), against $16,550 federal (29 CFR 1903.15(d)(3)). The willful and repeat cap, $162,851, is slightly below the federal $165,514.
• Criminal prosecution: Labor Code §6425 creates jail and prison exposure for willful violations that cause death or permanent or prolonged impairment.
• Written plans: every California employer must have a written IIPP (Title 8 §3203(a)), and §1512(i) separately requires a written emergency medical services plan.
• Heat Illness Prevention: §3395 is a final outdoor heat standard, which federal OSHA does not have, and it adds emergency response procedures (§3395(f)).

If you just took over as safety coordinator anywhere in California: assume everything you learned about federal OSHA is the starting line, then add the California layers below.

Cal/OSHA First Aid Requirements: Title 8 §1512

§1512 ("Emergency Medical Services") is the construction first aid rule. Its language is performance-based ("suitable number," "appropriately trained"), not a list of fixed ratios.

Common myth, corrected: §1512 does not say "one certified person per shift." It says "a suitable number of appropriately trained persons." Document why your number is suitable.

How California Exceeds Federal Requirements

California's IIPP Requirement and First Aid

Every California employer must maintain a written Injury and Illness Prevention Program under Title 8 §3203(a): who is responsible, how compliance is ensured, how hazards are communicated, inspected, investigated and corrected, and how workers are trained. §3203 does not name first aid; §1512(i) requires the written emergency medical services plan, and many employers keep it with the IIPP. Either way, it should cover:

1. Designated first aid responders — names, certifications, and assigned areas.
2. First aid procedures — step-by-step for the injury types your trades actually face.
3. First aid kit locations — mapped, weatherproof, and accessible.
4. Emergency contact and transport plan — 911, nearest ER, and how an injured worker is moved (§1512(e)).
5. Training schedule — initial and refresher dates, with a tracking system.
6. Incident reporting and review — how first aid is logged and root-caused.

If the emergency medical services plan isn't in writing, §1512(i) is not met, however well stocked the kit is.

Heat Illness Prevention: California's Unique First Aid Layer

California's Heat Illness Prevention Standard, Title 8 §3395, adds emergency-response duties that have no federal counterpart: there is no final federal heat standard as of October 2026, only a proposed rule (89 FR 70698) that would add 29 CFR 1910.148 and, for construction, 29 CFR 1926.67. §3395 applies to all outdoor places of employment, with heightened "high-heat" duties for construction starting at 95°F.

When It Applies

§3395's core duties (water, shade, training, written plan) apply to outdoor work; shade must be provided when the temperature exceeds 80°F, and the high-heat procedures kick in at 95°F (§3395(e)).

First Aid Kit Additions for Heat Illness

In addition to standard §1512 contents, stock for heat emergencies:

• Instant cold packs (multiple per kit) and, during high heat, ice on site.
• Cooling towels for active cooling of an overheated worker.
• Electrolyte replacement drinks or powders.
• A thermometer to help assess a worker showing symptoms.
• An emergency blanket that can double as improvised shade.

For a full plan, see our companion guides on the heat illness prevention plan, the 7–14 day acclimatization protocol, and whether there's an OSHA heat standard in 2026.

Worked Example: A 40-Worker Sacramento Concrete Pour in August

A general contractor runs a 40-worker cast-in-place concrete job in Sacramento. Forecast high: 101°F. Here is the California-specific first aid stack:

1. §1512(b) responders: with 40 workers across a large pour, the GC designates 2 trained responders per shift and writes down why that number is suitable in the §1512(i) plan.
2. §1512(c) kit: one weatherproof kit per active work zone; no aspirin or burn ointment unless an employer-authorized licensed physician approves them in writing (§1512(c)(3)).
3. §1512(f) eyewash: wet concrete is caustic, so quick-drench/eyewash is staged at the pour for corrosive (alkaline burn) exposure.
4. §1512(e) transport — Posted ER number, the closest ER's address/route, and a designated vehicle + driver identified for prompt transport.
5. §3395 heat — At 101°F the site is in high-heat (≥95°F) mode: ≥1 qt water/worker/hour, shade structures, mandatory pre-shift heat meeting, buddy-system observation, and cool-down rest available on demand.
6. §1512(i) and §3203: all of the above is in the written emergency medical services plan, kept with the IIPP, with the responder list, training dates, and the day's heat plan attached.

Skip the heat plan and a §3395 citation, which can be classified serious (up to $25,000 under §336(c)), can sit on top of a §1512 first aid citation. If a worker dies after a willful violation, Labor Code §6425 criminal exposure is on the table.

What to Have Ready for a Cal/OSHA Inspection

Have these ready.

Phase 1: Document Review

1. IIPP (§3203) and the §1512(i) emergency medical services plan, written and current.
2. First aid / CPR certifications — current cards for every designated responder.
3. Heat Illness Prevention Plan (§3395) — written, site-specific.
4. Emergency / transport plan — posted numbers and the §1512(e) transport arrangement.
5. Kit inspection logs — regular checks and prompt restocking.
6. Training records — first aid, CPR, heat illness, and bloodborne pathogens.

Phase 2: Physical Inspection

1. First aid kits — weatherproof, located, accessible, stocked, in date.
2. Eyewash — present where corrosives (incl. wet concrete) are used (§1512(f); federal 29 CFR 1926.50(g)).
3. Posting — emergency numbers and ER route per §1512(e); the federal rule, 29 CFR 1926.50(f), also asks for the site's location where 911 does not receive it.
4. Water and shade — §3395 quantities and shade availability.
5. AED — if present, maintained and workers trained.

Phase 3: Worker Interviews

Expect questions to workers such as:

• "Who is the first aid person on this site?"
• "Where is the nearest first aid kit?"
• "What would you do if a coworker collapsed?"
• "Where is the nearest hospital, and how would we get someone there?"
• "Have you been trained on heat illness — and where's the water?"

Train the people, not just the binder: §1512(d) requires every employee to be told the procedure to follow in case of injury or illness.

Reporting a Serious Injury Is Faster in California

Title 8 §342(a) requires an employer to report a serious injury or illness, or a death, to Cal/OSHA immediately, meaning as soon as practically possible and no later than 8 hours after the employer knows or with diligent inquiry would have known of it. Federal OSHA's clock is 8 hours for a fatality but 24 hours for an in-patient hospitalization, amputation or loss of an eye (29 CFR 1904.39(a)(1) and (a)(2)).

California Regional Considerations

Site risk varies a lot across the state — plan first aid capability around your EMS response time, not just headcount.

Hazards That Shape First Aid Planning

• Wildfire smoke: Cal/OSHA's Wildfire Smoke Standard, §5141.1, applies when the current AQI for PM2.5 is 151 or greater and smoke exposure is reasonably anticipated. From 151 to 500, respirators such as N95s must be provided for voluntary use; above 500, respirator use is required. First aid training should cover respiratory distress.
• Inland heat: on days at or above 95°F, the §3395(e) high-heat procedures apply.
• Remote sites: the farther the site from emergency care, the more §1512(b)'s "suitable number" and §1512(e)'s transport arrangements have to carry. Measure the drive to the nearest emergency room for each site and write it into the plan.

The Real 2026 Cal/OSHA Penalty Numbers

Cal/OSHA civil penalty maximums are set by Title 8 §336. The amounts below became operative January 1, 2025, the latest amendment in the section's history as of October 5, 2026.

Federal maximums are the amounts in 29 CFR 1903.15(d) as of September 25, 2026, which still apply to penalties proposed after January 15, 2025. Cal/OSHA serious violations are the headline difference: $25,000 vs. $16,550 federal.

Run your own numbers with the OSHA Fine Calculator. It models the federal gravity-based method; Cal/OSHA computes penalties under §335 and §336, so treat the calculator's output as federal only.

Criminal Penalties in California (Labor Code §6425)

California's criminal provision reaches further than the federal one, OSH Act §17(e). Under Labor Code §6425(a), a willful violation of a safety standard that causes death or permanent or prolonged impairment can bring:

• Individual: up to 1 year in county jail and a $100,000 fine, or 16 months, two or three years in state prison and a $250,000 fine.
• Corporation / LLC: a fine of up to $1,500,000; §6425(b) raises it for a conviction within seven years of certain earlier ones.
• Personal exposure: any employee having "direction, management, control, or custody" of the employment or of other employees can be charged individually.

Building Your California-Compliant First Aid Program

Step 1 — Assess your risk profile

Map every jobsite, measure EMS response times, and identify hazards (heights, corrosives/wet concrete, confined spaces, heat). Count workforce per site, per shift.

Step 2 — Determine staffing

§1512(b) sets no ratio: it requires a suitable number of appropriately trained persons and lets employers on one project pool them. Set your number from crew size per shift, the hazards of the work, and the time to emergency care, and write the reasoning into the §1512(i) plan.

Step 3 — Select a training provider that offers

• Hands-on skills practice, from the Red Cross or an equivalent provider (§1504).
• Construction-specific scenarios and CPR/AED.
• Heat illness response (the training §3395(h) requires).
• Stop the Bleed / hemorrhage control.
• Bloodborne Pathogens training (Title 8 §5193; the federal counterpart is 29 CFR 1910.1030).
• Spanish-language options for the California workforce.

Step 4 — Equip your sites

Weatherproof kits stocked to §1512(c)'s table or a licensed physician's list, eyewash where corrosives are present, heat-illness supplies, and an AED where EMS response is slow.

Step 5 — Document everything

Written IIPP and §1512(i) emergency medical services plan, Heat Illness Prevention Plan, designated-responder list, certification tracker, kit-inspection logs, training sign-ins, and first aid/incident logs. Build your plan fast with the Emergency Action Plan Builder and the Heat Illness Prevention Builder.

Key Takeaways

1. California requirements are stricter than federal — treat 29 CFR as the floor.
2. §1512 is performance-based ("suitable number," weatherproof kit, physician approval for medicines, posted numbers, a written plan); document why your program is suitable.
3. Two written documents: the IIPP (§3203) and the emergency medical services plan (§1512(i)).
4. §3395 heat adds an emergency-response layer with an 80°F shade trigger and 95°F high-heat duties.
5. The real 2026 caps: serious $25,000, willful/repeat $162,851 (willful min $11,632).
6. Criminal exposure: Labor Code §6425 reaches state prison and up to $250,000 for individuals, and $1.5M for corporations.
7. §1512(d): every worker must know the procedure to follow in case of injury or illness.
8. Add Bloodborne Pathogens (§5193) compliance to your first aid program.
