Most Common Violations of CCR §5164: Hazardous Substance Storage in Maritime Operations

California's maritime docks hum with activity, but one slip in hazardous substance storage can turn the tide from smooth operations to Cal/OSHA citations. Section 5164 of Title 8 CCR sets strict rules for storing flammables, toxics, corrosives, and oxidizers at cargo handling facilities. We've audited enough terminals to spot patterns—here are the top violations sinking compliance.

Violation #1: Failing to Segregate Incompatible Materials

This tops the list, clocking in at over 30% of §5164 citations per Cal/OSHA data. Acids next to bases? Flammables cozying up to oxidizers? Recipe for disaster.

I've walked piers where drums of hydrochloric acid sat shoulder-to-shoulder with sodium hydroxide, ignoring §5164(d)'s segregation mandates. The result? Potential reactions releasing toxic fumes or fires. Pro tip: Use berms, secondary containment, and a compatibility chart from NFPA 704 or Appendix A of CCR §5164. Segregate by at least 20 feet or with barriers—non-negotiable for toxics and flammables.

Violation #2: Storage Near Ignition Sources or Exits

Short and stark: No hazmat within 20 feet of ignition sources, per §5164(c). Sparks from welding, open flames, or even hot work zones? Common culprits in shipping yards.

We once consulted a Long Beach terminal hit with fines after storing flammable solvents under electrical panels. The inspector flagged it instantly. Keep 50 feet from rail lines or vehicle routes, and 10 feet from exits. Reference OSHA 1917.24 for parallel maritime standards—alignment keeps you audit-ready.

Violation #3: Inadequate Spill Control and Containment

§5164(e) demands dikes, drains, or absorbent materials for spills. Yet, terminals overload docks without overflow protection, courting environmental violations alongside safety ones.

Picture this: A ruptured corrosive drum floods a loading area because no secondary containment was in place. We've seen it lead to NPDES permit issues under Clean Water Act crossovers. Install sumps capable of holding 110% of the largest container's volume. Stock spill kits with specifics for your inventory—universals for oils, neutrals for acids.

• Quick Audit Checklist:
• Measure distances to hazards.
• Verify container approvals (DOT-spec).
• Confirm ventilation per §5164(f)—MEK vapors don't dissipate on breezes alone.

Violation #4: Poor Labeling and Quantity Limits Exceeded

Labels faded? Quantities creeping over 660 gallons for Class IA liquids? §5164(g) and (h) don't forgive. Unmarked drums invite mishandling; we've traced incidents to 'ghost' containers.

Cal/OSHA logs show this violation spiking during high-volume seasons. Max out at table limits: 60 gallons IA indoors, more outdoors with cabinets. Use GHS-compliant labels with pictograms—beyond basic NFPA diamonds for maritime scrutiny.

Violation #5: Ventilation and Housekeeping Oversights

Airy storage sounds ideal, but §5164(f) requires mechanical ventilation at 1 cfm/sq ft for vapors. Dust accumulation on rafters? Housekeeping fail under §5164(i).

In foggy Bay Area ops, natural ventilation fools no one. We recommend continuous monitoring for toxics like benzene. Pair with daily sweeps—flammable residues ignite faster than you think.

These violations aren't abstract; they're drawn from Cal/OSHA's public citation database and our fieldwork across SoCal ports. Compliance slashes risks—fewer evacuations, lower premiums. Cross-check with USCG regs for vessel interfaces. Individual setups vary, so tailor to your JHA. For depth, dive into Cal/OSHA's enforcement summaries or ANSI Z87.1 for PPE tie-ins.
