Class Code 4362
Motion Pictures – Negative And Print Processors
Class Code 4362 covers workers who process motion picture negatives and prints using chemical baths and mechanical processing equipment. The approved pure premium rate for California effective September 1, 2026 is $1.046 per $100 of payroll. Understanding this classification helps employers control exposure, maintain compliance, and budget workers' comp costs.
What Class Code 4362 Covers
This classification applies to operations that develop, fix, wash, dry, and otherwise chemically process motion picture film and photographic prints — typically in a lab or on-location processing truck. It includes handling developer, stop bath, fixer and stabilizer chemistries; operating continuous or batch film processors and drying units; splice and printing operations; and silver recovery and wastewater handling tied to film chemistry. Routine maintenance and cleaning of processors, conveyor and reel systems, filtration, and solvent or chemical cleaning of rollers are included when performed by processing personnel. Purely digital editing, dailies screening without chemical processing, or camera operation are not included unless the employee also performs the chemical processing tasks described above.
Who It Applies To
- Laboratory technicians in motion picture and film processing labs
- Independent film processing shops that develop negatives and make prints
- Post-production facilities that maintain on-site chemical processors
- Mobile/on-location processing vans that develop dailies
- Maintenance staff assigned to processing machines and silver recovery systems
Common Job Duties
- Loading and threading film through continuous or batch chemical processors
- Mixing, testing and adjusting developer, fixer, stop bath and stabilizer solutions
- Operating processors, dry cabinets, rollers, and refrigeration/temperature control systems
- Performing routine cleaning, filter changes, roller maintenance and minor machine repairs
- Monitoring chemical concentrations and bath life, recording process data, and disposing of spent solutions
- Recovering silver and managing waste streams or coordinating with certified waste haulers
- Splicing, trimming, drying, and packaging finished prints or negatives
Common Injury Risks
Understanding the $1.046 Rate
The pure premium rate of $1.046 per $100 of payroll represents the portion of workers' compensation pricing that estimates expected claims costs (paid losses) for this class before insurer expenses, profit, and assessments. Employers multiply that rate by payroll in hundreds of dollars to calculate the pure premium portion; their final premium is adjusted by their insurer's loss cost multipliers, experience modification, credits/penalties, and state assessments. Payroll classification accuracy, loss history, safety programs, and audits can materially affect the actual premium paid.
Cal/OSHA Compliance Requirements
Cal/OSHA requires employers to control chemical hazards through a written hazard communication program with SDS access and labeling, employee training, and exposure controls. Engineering controls such as local exhaust ventilation, properly hooded processing rooms, and temperature control reduce vapor exposure; where exposures exceed limits, respiratory protection programs, fit testing, and medical surveillance are required. Employers must also provide appropriate PPE (chemical-resistant gloves, splash goggles or face shields), eyewash and emergency shower access, and safe procedures for silver recovery and hazardous waste handling under state environmental rules.
How Key HR Helps Employers Under Class Code 4362
A PEO like Key HR can help employers in this class reduce workers' comp costs by centralizing claims reporting and management, delivering targeted loss-control programs (chemical handling training, ventilation assessments, PPE programs), and assisting with classification audits to ensure payroll is assigned correctly. Key HR also provides SDS management, return-to-work and transitional duty programs to shorten claim durations, and access to safety consultants who can design silver recovery and hazardous-waste handling protocols to limit exposures and regulatory risk.
Get a QuoteFrequently Asked Questions
Does Class Code 4362 apply to digital post-production or film editors?
No. Class Code 4362 specifically covers chemical processing of motion picture negatives and prints. Purely digital editing, color grading, or non-chemical dailies screening are typically classified differently unless the worker also performs chemical processing tasks.
What steps most reduce workers' comp claims and premiums for a film processing lab?
Key measures are strict chemical handling training, proper local exhaust ventilation, required PPE and eyewash stations, machine guarding and lockout/tagout for processors, regular housekeeping to prevent slips, documented silver recovery and waste disposal, and an active return-to-work program. These controls reduce both injury frequency and severity, improving your experience modification and premiums.
How can Key HR help with hazardous waste and silver recovery compliance?
Key HR can connect employers with environmental compliance partners, help implement documented silver-recovery programs, maintain SDS and training records, and coordinate with certified waste haulers. We also advise on permitting and reporting obligations so the employer reduces regulatory risk while limiting exposures that drive workers' comp claims.
