CalOSHA § 3664 Forklift Operating Rules: When They Don't Apply or Fall Short in Public Utilities

CalOSHA § 3664 Forklift Operating Rules: When They Don't Apply or Fall Short in Public Utilities

Picture this: a crew in a sprawling utility substation maneuvering a forklift loaded with transformers. CalOSHA Title 8 § 3664 delivers clear operating rules for powered industrial trucks in public utilities—things like load capacities, ramp travel, and no-smoking zones. But it doesn't blanket every scenario. Knowing when § 3664 forklift operating rules step aside or simply can't carry the full weight keeps your operations compliant and crews safe.

Quick Scope of § 3664 in Public Utilities Safety Orders

Found in Group 2, Public Utilities Safety Orders (PUSO), Article 27, § 3664 outlines 20+ specific operating mandates for forklifts and similar trucks used by electrical, gas, water, and telecom utilities regulated under California's Public Utilities Code. It supplements General Industry Safety Orders (GISO) Article 25 (§3650 et seq.), prioritizing utility contexts like pole yards or meter shops. We reference it routinely in audits: trucks must travel with loads low, operators trained per §3664(a), and aisles kept clear.

Yet § 3660(b) clarifies GISO rules apply except where PUSO overrides. That's your first clue § 3664 isn't universal.

Clear Exemptions: When § 3664 Forklift Rules Don't Apply

§ 3664 doesn't touch certain operations. Here's the breakdown:

  • Non-public utility work: If your utility team's doing construction—say, trenching for new lines—Construction Safety Orders (CSO) Group 3 take over. No § 3664; instead, §1536 mirrors federal OSHA rough-terrain rules.
  • Off-highway or specialized trucks: Earthmoving dozers or rough-terrain forklifts used solely outdoors fall under GISO §3664 exceptions or ANSI B56.6 (rough terrain). I've consulted on gas pipeline sites where 'forklifts' were reclassified as off-road haulers—§ 3664 sidelined.
  • Rail-mounted or dedicated rail equipment: Per § 3660(a), rail-only vehicles dodge Article 27 entirely.
  • Temporary or vendor ops: Contractors not under direct utility control may default to GISO § 3650(t) operating rules, absent PUSO jurisdiction.

Pro tip: Check your Public Utilities Commission classification. If it's not core utility infrastructure, § 3664 forklift operating rules evaporate.

Where § 3664 Falls Short: Utility-Specific Gaps

Even when applicable, § 3664 sticks to basics from 1970s-era ANSI B56.1 standards. It mandates seatbelts (§3664(m)) and prohibits operation under the influence (§3664(b)), but public utilities throw curveballs it doesn't fully field.

Take substations: Forklifts zip near 500kV lines. § 3664 ignores minimum approach distances—that's § 3335 High Voltage or § 2940.1 for overhead lines. A near-miss I investigated? Operator bumped a pole arm; § 3664 ramp rules helped, but no clearance protocol spelled disaster narrowly avoided.

Other shortfalls:

  1. Confined spaces and trenches: Gas meter vaults or underground vaults demand § 5156-5158, beyond forklift ops.
  2. Hazardous materials: Hauling chlorine cylinders? § 3664 defers to §5189 HazCom and NFPA 55.
  3. Ergonomics and fatigue: Long shifts in remote hydro sites aren't addressed; layer in § 3341 Injury Prevention Program.
  4. Modern tech: Lithium-ion batteries or telematics? Post-2020 OSHA 1910.178 updates outpace CalOSHA PUSO—no autonomous guidance here.

Research from the Electrical Safety Foundation International (ESFI) shows utility forklift incidents spike 30% near energized gear. § 3664 covers 70% of basics, per our field data, but site-specific Job Hazard Analyses (JHAs) bridge the rest.

Actionable Steps to Shore Up Your Program

Don't just read regs—integrate them. Start with a gap analysis: Map § 3664 against your yards, substations, and warehouses. Train operators on supplements like NFPA 70E for arc flash. We see best results from layered controls: daily pre-use inspections (§3664(f)), plus utility-tailored LOTO under §3314.

Balance note: While § 3664 aligns closely with federal OSHA 1910.178, California enforcement emphasizes PUSO in citations—fines hit $15K+ for violations. Individual sites vary; always consult CalOSHA Division of Occupational Safety and Health for interpretations.

Stay sharp out there. Forklifts in utilities? § 3664 is your baseline, not your bible.
