Section 9.3: OSHA Standards & Prep Room Operations

1. OSHA Regulatory Compliance in Mortuary Science

The Occupational Safety and Health Administration (OSHA) is a federal agency under the U.S. Department of Labor responsible for ensuring safe and healthful working conditions. In a funeral home, the preparation room is the most hazardous area due to biological hazards (pathogens) and chemical hazards (formaldehyde, glutaraldehyde, phenol). Employers must comply with three primary OSHA standards in this space: the Bloodborne Pathogen Standard, the Formaldehyde Standard, and the Hazard Communication Standard.

2. OSHA Bloodborne Pathogen Standard (29 CFR 1910.1030)

This standard is designed to protect workers from occupational exposure to blood or other potentially infectious materials (OPIM) that may contain bloodborne pathogens.

• Exposure Control Plan (ECP): Employers must maintain a written, site-specific plan designed to eliminate or minimize employee exposure. It must be updated at least annually.
• Universal Precautions: An approach to infection control where all human blood and body fluids are treated as if they are known to be infectious for HIV, HBV, HCV, and other bloodborne pathogens. There are no exceptions; every body is treated identically.
• Engineering Controls: Technology-based controls that isolate or remove the bloodborne pathogen hazard from the workplace. Examples include:
  • Eyewash stations and emergency drench showers.
  • Local exhaust ventilation systems.
  • Puncture-resistant sharps disposal containers.
  • High-rimmed embalming tables and sinks with backflow preventers (vacuum breakers).
  • Lavatory sinks with foot or knee pedals.
• Work Practice Controls: Behavioral controls that reduce the likelihood of exposure by altering the manner in which a task is performed. Examples include:
  • Washing hands immediately after removing gloves.
  • Prohibiting the recapping, bending, or breaking of needles using a two-handed method (a one-handed 'scoop' technique or mechanical device must be used if recapping is necessary).
  • Placing all sharps in designated containers immediately after use.
  • Prohibiting eating, drinking, smoking, applying cosmetics, or handling contact lenses in the prep room.
  • Minimizing splashing and aerosolization during aspiration.
• Personal Protective Equipment (PPE): The employer must provide appropriate PPE at no cost to the employee. In the prep room, standard PPE includes:
  • Fluid-resistant gowns or aprons.
  • Double-gloving (nitrile or latex gloves).
  • Face shields and safety goggles (to protect eyes and mucous membranes from splashes).
  • Surgical masks or respirators.
  • Shoe covers or rubber boots.
• Hepatitis B Vaccination: Employers must make the Hepatitis B vaccine series available to all employees who have occupational exposure within 10 working days of initial assignment. The vaccine must be offered at no cost to the employee. If an employee declines, they must sign a specific OSHA declination form, but they can still request and receive the vaccine at a later date.
• Post-Exposure Evaluation: Following an exposure incident (e.g., needlestick or splash), the employer must provide a confidential medical evaluation and follow-up, including documenting the route of exposure, identifying the source individual (if feasible), testing the source's blood (with consent), and offering post-exposure prophylaxis.

3. OSHA Formaldehyde Standard (29 CFR 1910.1048)

Formaldehyde is a colorless, strong-smelling gas widely used in embalming fluids. It is classified as a human carcinogen and sensitizer, posing respiratory and skin hazards. The Formaldehyde Standard sets strict limits on occupational exposure.

• Permissible Exposure Limits (PEL):
  • Time-Weighted Average (TWA): The maximum average exposure limit over an 8-hour workday. The TWA is 0.75 ppm (parts per million).
  • Short-Term Exposure Limit (STEL): The maximum exposure limit over a 15-minute period. The STEL is 2.0 ppm.
  • Action Level (AL): The threshold level that triggers compliance activities, measured over an 8-hour workday. The Action Level is 0.5 ppm.
• Exposure Monitoring:
  • Employers must conduct initial monitoring to determine exposure levels for all employees who may be exposed to formaldehyde.
  • If the monitoring results are below the Action Level (0.5 ppm TWA) and below the STEL (2.0 ppm), no further monitoring is required unless there is a change in production, equipment, process, or controls.
  • If the results meet or exceed the Action Level (0.5 ppm TWA): Monitoring must be repeated at least every 6 months. The employer must also initiate medical surveillance, including a medical questionnaire and physical examination.
  • If the results exceed the PEL (0.75 ppm TWA) or the STEL (2.0 ppm): Monitoring must be repeated at least every 3 months. The employer must immediately implement engineering and work practice controls to reduce exposure, post warning signs on the door ('DANGER - FORMALDEHYDE - IRRITANT AND POTENTIAL CANCER HAZARD - AUTHORIZED PERSONNEL ONLY'), and provide respirators to employees until exposure levels are reduced below the limits.
• Engineering and Work Practice Controls:
  • Ventilation: Effective ventilation is critical. A prep room should have a dedicated exhaust system that pulls air away from the embalmer and exhausts it outside. Because formaldehyde gas is heavier than air, exhaust vents should be located close to the floor, and fresh air intake vents should be located near the ceiling. The system should provide 12 to 15 air changes per hour (minimum of 10).
  • Covering Drains: Keeps formaldehyde vapors from evaporating from waste water.
  • Capping Bottles: Standard practice of keeping caps on chemical bottles.
  • Water wash: Running a continuous stream of water on the table to wash away chemical run-off.
  • Lid on Embalming Machine: Keeping the lid on the reservoir tank.

4. OSHA Hazard Communication Standard (29 CFR 1910.1200)

Commonly known as the 'Right to Know' law, this standard ensures that employees are aware of the chemical hazards they work with.

• Safety Data Sheets (SDS): Manufacturers must provide an SDS for every hazardous chemical. Employers must maintain a complete binder or electronic database of these SDSs that is readily accessible to employees at all times. The SDS contains 16 standardized sections detailing the chemical's hazards, handling, storage, and emergency measures.
• Labeling: Every container of hazardous chemicals in the prep room must be clearly labeled with:
  • Product identifier (name).
  • Signal word ('Danger' for severe hazards, 'Warning' for less severe).
  • Hazard statements (e.g., 'Causes skin irritation').
  • Pictograms (e.g., skull and crossbones, flame).
  • Precautionary statements.
  • Manufacturer information.
• Training: Employees must receive training on chemical hazards at the time of their initial assignment and whenever a new chemical hazard is introduced into their work area.
