Firefighter Cancer Prevention: The Gear You're Forgetting to Decontaminate

Firefighter cancer prevention has changed the way departments think about contaminated gear.

Turnout gear is cleaned. Hoods are washed. SCBA components are addressed. Departments increasingly separate contaminated equipment from clean areas of the station.

But what about the radio strap?

A firefighter radio strap can accompany you into the same environments as the rest of your equipment, yet it may never make it into the department’s regular cleaning routine. For chiefs and safety officers developing comprehensive exposure-reduction programs, that raises a straightforward question: If equipment can become contaminated, how will it be cleaned?

That question matters. The International Agency for Research on Cancer (IARC), the cancer agency of the World Health Organization, classifies occupational exposure as a firefighter as carcinogenic to humans (Group 1).

Cancer prevention cannot eliminate every occupational hazard firefighters face. What departments can do is continue looking for practical opportunities to reduce unnecessary exposure, including the equipment that is easy to overlook.

Why Is Cancer Prevention Such an Important Issue in the Fire Service?

Firefighters can encounter complex mixtures of hazardous substances on the job, including polycyclic aromatic hydrocarbons (PAHs), particulates, diesel exhaust, asbestos, flame retardants, and other combustion products.

Research from NIOSH underscores why exposure reduction deserves department-wide attention.

A study of nearly 30,000 career firefighters from Chicago, Philadelphia, and San Francisco found 9% more cancer diagnoses and 14% more cancer-related deaths than expected based on U.S. population rates.

Those statistics don't mean every firefighter will develop cancer, nor can cancer risk be attributed to a single piece of equipment. Firefighting involves numerous exposures over the course of a career.

The takeaway for departments is simpler: reducing avoidable occupational exposure wherever practical should remain a priority.

How Can Contaminated Gear Contribute to Continued Exposure?

The hazard doesn't necessarily end when the fire is extinguished.

NIOSH explains that hazardous substances can transfer from contaminated gear onto firefighters' skin, other equipment, apparatus, and areas within the station. The agency identifies cleaning gear and skin, properly removing contaminated gear, and appropriate bagging and storage as measures that can help reduce exposure.

NIOSH has also noted that firefighters can encounter cancer-causing chemicals through inhalation, skin or eye contact, and ingestion, with exposure potentially continuing through turnout gear that has not been properly cleaned or stored.

This is why decontamination needs to be viewed as a system, rather than something reserved for a turnout coat and pants.

If equipment goes into a contaminated environment, it deserves consideration in the department's post-incident process.

Is Your Radio Strap Part of Your Decontamination Routine?

Think about where a radio strap goes during an average shift.

It may be worn during fireground operations, EMS calls, vehicle incidents, training exercises, and other responses. It is touched by gloved and bare hands, comes into contact with other equipment, and is worn close to the body.

Then ask another question: When was it last thoroughly washed?

For some departments, radio straps fall into a gap between communications equipment and PPE. Everyone knows they are used constantly, but responsibility for cleaning them may not be clearly addressed.

For a safety officer reviewing departmental procedures, that's an opportunity.

Consider auditing frequently worn equipment and asking:

• Does it enter contaminated environments?
• Is it handled before, during, or after incidents?
• Can it be properly laundered?
• Does the manufacturer provide cleaning instructions?
• Is cleaning included in department SOPs or SOGs?
• Are personnel actually cleaning it at an appropriate frequency?

The radio strap is one example of why firefighter cancer prevention should extend beyond the most obvious pieces of PPE.

Why Does Launderability Matter?

The point isn't that one radio strap material "causes cancer." It doesn't. The relevant distinction is launderability.

A department trying to reduce residual contamination needs equipment that can tolerate the cleaning method required for that equipment without being unnecessarily damaged.

NIOSH continues to study turnout-gear laundering because contaminants can remain trapped on or within gear and potentially contribute to continued exposure. Its research reinforces the broader importance of effective cleaning as one component of exposure reduction.

That same principle is worth considering when evaluating other frequently exposed equipment. If a radio strap cannot tolerate routine washing, maintaining a consistent decontamination program becomes more difficult.

How Do Leather and Washable Nylon Radio Straps Differ?

Leather has a long history in the fire service, and this discussion should not be interpreted to mean that leather itself is carcinogenic.

The practical issue is cleaning. Leather typically requires specialized care and may not be appropriate for the same laundering processes used for washable synthetic equipment. Repeated soaking, detergents, and mechanical washing can affect the leather's condition.

Extractor-washable nylon provides another option. An H6 nylon radio strap is designed to be washed, allowing departments to incorporate the strap into a regular cleaning program rather than relying primarily on surface wiping.

The distinction is important: washable nylon doesn't eliminate firefighter cancer risk.

What it can do is remove one practical barrier to regularly cleaning a piece of equipment that may otherwise be overlooked.

What Should Chiefs and Safety Officers Review?

Cancer-prevention initiatives work best when they become part of department culture rather than an occasional reminder.

For chiefs, health and safety officers, and PPE committees, consider reviewing more than turnout gear alone.

Look at the routinely used equipment that travels between the hot zone, apparatus, and station.

Ask whether each item has:

1. A defined cleaning procedure.
2. A responsible person or role for ensuring it gets cleaned.
3. Manufacturer-approved laundering instructions.
4. A replacement policy when it can no longer be adequately maintained.
5. A place within the department's broader exposure-reduction strategy.

NIOSH specifically emphasizes preventing contaminants from traveling from the incident scene into apparatus, stations, personal vehicles, and homes. That makes overlooked equipment worthy of attention.

Can Changing a Radio Strap Prevent Firefighter Cancer?

No single piece of equipment can prevent firefighter cancer. Cancer risk is complex, and firefighter exposures can come from many sources throughout a career. IARC's classification itself evaluates occupational exposure as a firefighter, not one individual material or piece of gear.

Switching to a washable radio strap should therefore be understood as one component of a broader exposure-reduction strategy.

The objective is not to promise prevention. It is to make decontamination easier to perform consistently. And when departments are examining every reasonable way to reduce unnecessary exposure, that distinction matters.

Is It Time to De-con the Strap?

Firefighter cancer prevention is built from many individual decisions: what gets worn, where contaminated equipment goes, how it is handled, and whether it can be effectively cleaned before returning to service. The radio strap deserves a place in that conversation.

Homeland-Six developed its military-grade nylon radio straps to be extractor washable, giving firefighters and departments a cleanable alternative to traditional radio strap materials. For chiefs and safety officers, that means the strap can become part of a broader decontamination strategy instead of remaining a forgotten piece of gear.

Frequently Asked Questions

Why should firefighters decontaminate their radio straps?

Radio straps may be present in contaminated environments and are frequently handled throughout a shift. Cleaning them can help prevent residual contaminants from remaining on equipment or transferring to other surfaces.

Does a leather radio strap cause cancer?

No. Leather radio straps should not be described as causing cancer. The concern is whether exposed equipment can be appropriately cleaned. Leather requires material-specific care, while washable nylon provides departments with an option designed for routine laundering.

Can washing a radio strap prevent firefighter cancer?

No cleaning practice or radio strap can guarantee cancer prevention. Routine cleaning should instead be viewed as one part of a comprehensive strategy intended to reduce unnecessary occupational exposure.

Are H6 radio straps extractor washable?

Yes. H6 nylon radio straps are designed to be extractor washable, making them easier to incorporate into department equipment-cleaning procedures.

How often should firefighters clean their radio straps?

Cleaning frequency should follow manufacturer instructions and department policies, with particular attention after contamination or significant fireground exposure. Departments should consider including radio straps when developing routine equipment inspection and decontamination procedures.

What other gear should departments consider when reviewing decontamination procedures?

Departments should evaluate equipment that may become contaminated during operations, including turnout gear and other frequently handled or worn equipment. NIOSH recommends practices aimed at limiting the transfer of contaminants from incident scenes to firefighters, apparatus, stations, and other environments.
