Expert Advice on Contaminated Gear Hazards and Cleaning

Haley Jorgensen interviews experts who report on how contaminated gear exposes firefighters to potentially life-threatening chemicals, biological agents and particulates and can even pass on contaminants to the public.


Firefighters are already exposed to so much,” says chemical engineer Jeffrey Stull, “why would they want to increase exposure by wearing contaminated clothing?” The truth is sobering. Contaminated protective gear exposes firefighters to potentially life-threatening chemicals, biological agents...

Joel Jorgensen, an industrial laundry equipment expert, agrees. Director of marketing and sales at Continental Girbau Inc., Jorgensen holds 10 years of experience in the laundry industry. He warns that a careful approach to cleaning gear is critical to proper decontamination and to maintaining the integrity of the protective fabric.

“A highly programmable washer-extractor is key to washing gear correctly,” Jorgensen says, “in order to avoid damage to the gear itself.” Fire departments should use washer-extractors offering programmable water temperatures and levels, extract speeds, multiple baths, and automatic chemical (detergent) injection. They should also be able to program multiple wash actions, cylinder rotation options, and wash time.

Protective gear, Jorgensen adds, should be cleaned according to NFPA 1851 and manufacturers’ guidelines – at the right water temperature and using correct detergents. A washer-extractor programmed to automatically inject the right type and quantities of detergents at the appropriate water temperature and level, will prevent inconsistent and damaging results. “Automatic injection is especially critical at fire departments where more than one firefighter handles the laundry,” Jorgensen says. “You just touch a button and the machine handles the rest. It means no one is going to throw the wrong quantity or type of chemicals – like bleach – in the load, which could damage the gear.”

Air drying gear, according to Stull, is among the best ways to decontaminate gear. “The drying of gear is important,” he says. “It allows clothing materials to off gas.” In other words, gear will continue to decontaminate during the air-drying process – a necessary step. “The best way to dry the gear is to hang it in a well-ventilated room with a slightly higher than ambient temperature of up to 105 degrees,” says Stull, who warns that use of a standard tumbler-dryer is degrading and damaging to protective fabrics.

Decontaminating gear seems a complicated process. But, according to Jorgensen, it doesn’t have to be. “Once the washer-extractor is properly programmed, it’s a piece of cake,” he says. Fire departments should seek out a reputable chemical supply company with a representative accustomed to programming washers for cleaning protective apparel.

In the past, dirty gear was the norm – a badge of courage, according to Stull. But, that trend is changing. Firefighter safety is now a fire department’s number one concern. Eliminating exposure to hazards by decontaminating gear is today, a priority.

“Not washing gear is bad,” says Stull. “It’s not healthy to be continually exposed to contaminants. No one knows if it takes two or three years of exposure to cause harm. This is a form of exposure that doesn’t need to happen.”

5. Turn garment shells and liners inside out and place in a mesh laundry bag

6. Wash temperature not to exceed 105 degrees Fahrenheit

7. Add detergent

8. Run one complete cycle, rinsing at least twice

9. Dry the elements

10. Inspect and rewash if necessary

11. If the machine is to be used for other than protective ensemble elements rinse out machine by running while empty through a complete cycle with 120 to 125 degrees Fahrenheit
