Class Code 5185
Automatic Sprinkler Installation – Low Wage
Class Code 5185 covers low-wage automatic fire sprinkler installation work in California — typically installer helpers and entry-level installers who fit, hang, and test sprinkler pipe and heads. The September 1, 2026 approved pure premium is $5.190 per $100 of payroll, a baseline cost employers should understand when budgeting for workers' compensation.
What Class Code 5185 Covers
This classification applies to employees engaged primarily in installing automatic fire sprinkler systems on construction sites, in new buildings, or during major remodels where wages fall within the low-wage band used by carriers. Typical operations include laying out runs, cutting and threading light-gauge sprinkler pipe, installing hangers and brackets, mounting sprinkler heads, coupling pipe and fittings, and performing water-fill or hydrostatic testing. Work is usually performed inside framed structures, ceiling plenums, crawl spaces, on ladders or short scaffolds, and occasionally in shallow trenches. The code is intended for lower-paid installers/helpers rather than journeyman-level pipefitters doing heavy welding or full system design.
Who It Applies To
- Fire sprinkler contractor crews that employ entry-level installers or helpers
- Subcontractors on commercial and multi-family residential construction projects
- Companies performing new system installation (not primarily service/repair)
- Apprentices and laborers assigned to sprinkler layout, hanging, and testing
- General contractors hiring low-wage installer crews as a subcontracted trade
Common Job Duties
- Measuring, cutting, grooving, threading, and coupling light sprinkler pipe
- Installing hangers, clamps, brackets, and seismic restraints for pipe runs
- Mounting and orienting sprinkler heads and escutcheons per plans
- Running pipe through ceilings, walls, and cable trays; working in plenums
- Performing water-fill and hydrostatic tests and flushing systems
- Reading basic installation drawings and following fire protection layouts
- Carrying materials, handling ladders, and assisting journeymen with rigging

Understanding the $5.190 Rate
The pure premium rate of $5.190 per $100 of payroll represents the WCIRB's estimated loss cost for this classification and is the baseline used by insurers to price expected claim costs. Insurers apply this pure premium to your payroll, then add expense loads, state assessments, and your employer experience modification and policy-specific credits or debits to produce the final premium.
Cal/OSHA Compliance Requirements
Cal/OSHA construction standards apply: employers must comply with fall protection and ladder/scaffold rules, PPE and eye protection, hazard communication, and confined-space entry procedures when work requires it. Where cutting, grinding, or drilling occurs, respirable silica and welding/brazing rules may apply; hot work/fire prevention and training records are commonly required for sprinkler installation crews.
How Key HR Helps Employers Under Class Code 5185
A PEO like Key HR can help employers in Class 5185 reduce workers' comp costs by ensuring accurate payroll classification, implementing job-specific safety programs (ladder training, PPE, hot work permits), and managing claims and return-to-work plans to lower experience modification. Key HR also coordinates OSHA-required training, centralized claims advocacy, and periodic safety audits tailored to sprinkler installation crews.

How do I know if my crew belongs in the low-wage 5185 classification?
Classification depends on the primary duties and the wage band carriers treat as low-wage for sprinkler installation. If workers perform basic installation, hanging, and testing and are paid at entry-level rates, Class 5185 is typical. Payroll reporting and job descriptions determine the right code; your PEO or broker should review crew tasks and wages to confirm the correct assignment.
Can safety programs lower my premium for this class?
Yes. Consistent safety programs that reduce claim frequency and severity—ladder and scaffold training, PPE enforcement, hot work controls, pre-job hazard assessments, and return-to-work practices—can lower actual premiums by improving your experience modification and reducing insurer loss picks.
Is maintenance or repair work covered by 5185 or a different code?
Routine service, inspection, or repair work can be classified differently than new-system installation because exposures and pay rates often differ. Always document the scope of work and consult with your insurer or PEO to determine whether maintenance should be reported under Class 5185 or another applicable code.
