Study Notes

Purpose and Authority

Establishes a safe method for removing toxic particles from equipment and PPE after fire exposure.
Aims to reduce firefighter exposure and improve long-term health outcomes.
Governed by Fire Rescue Administrator, NFPA standards (1851, 1971-1974), and OSHA regulations (29 CFR 1910.156(e)(3)(ii)).

Scope

Applicable to all personnel involved in Emergency Operations.

On Scene Post Fire Gross Decontamination

Focuses on systematic decontamination after exposure to combustion products.
Required after all fire incidents where PPE is worn (structure, wildland, vehicle, training, other emergencies).

Preparation

Recommended to create a personal "Go-Bag" for quick access to a clean uniform post-exposure.
Suggested items include Class D uniform, clean socks and footwear, hat, towel, and sun protection.

Gross Decon Setup

Gross Decon should be located in the warm zone, close to the products of combustion.
The Driver Operator establishes and oversees the decontamination area.
Must use clean municipal water source to avoid contamination.
Designate the decon area with a green traffic cone and deploy a Decon Hose Line.

Gross Decon Process

Personnel should rinse off debris systematically, starting from the collar-line down.
Avoid saturating the inner lining of the Bunker gear to maintain operational readiness.
Soft bristle scrub brushes and Fire Rescue approved soaps may be utilized.
Follow NFPA 1851 and manufacturer guidelines for PPE cleaning.

Drop Zone

Separate area for leaving contaminated PPE, excluding of Bunker pants and structural boots.
Drop Zone should be remote and downwind of Rehabilitation to manage off-gassing.

Rehabilitation

Gross decontamination is mandatory before entering Rehabilitation.

Reporting for Re-Assignment

Crews returning to operations must report ready for assignment and re-do Gross Decon if further exposure to combustion products is expected.

Release from the Scene

Thoroughly perform Gross Decon before leaving the incident to prevent corruption of vehicle interiors.
Contaminated PPE must be bagged in approved Decon Bags, sealed and secured to minimize off-gassing.
All equipment must be cleaned on site with approved products.

Personal Protective Equipment Exchange

Complete thorough decontamination of PPE and vehicle cabs after exposure.
Return the vehicle to a ready state and ensure all gear is clean.

Ability to Respond

Clean Bunker gear should be stored appropriately to facilitate drying and off-gassing.
Use fans to enhance the off-gassing process, ensuring readiness without hindering response times.

Maintaining Readiness

Ensure vehicle cabs are clean to minimize secondary exposure risks.
Regular cleaning and decontamination of cabs are necessary for operational safety.
