You’ve just returned from a call. Your gear is wet and potentially contaminated, and it needs to be dried properly before the next alarm sounds. But proper drying isn’t as simple as hanging it over a chair. There’s a method that protects your gear’s protective qualities and, ultimately, protects you. Here’s what you need to know.
Why Drying Bunker Gear the Right Way Matters
Wet gear is more than uncomfortable, it’s a genuine health and safety risk. Moisture trapped within vapor barriers creates an ideal environment for bacteria, fungi, mold, and mildew to grow, increasing the risk of skin infections and persistent odors. Wearing damp gear during a call is distracting, and if the moisture hasn’t fully evaporated, you also face the very real danger of steam burns when exposed to intense heat.
Beyond the health angle, moisture compromises gear integrity over time. Damp thermal barriers lose insulating efficiency, water-repellent coatings degrade faster, and fabrics weaken from the inside out. Keeping your bunker gear thoroughly dry after every call isn’t optional, it’s part of maintaining the equipment that keeps you alive.
Proper drying starts with proper hanging. Flimsy wire or plastic hangers distort wet gear and stress seams under the weight of soaked turnout equipment. Shop Tough Hook Heavy-Duty Hangers → built to hold up to 200 lbs and designed specifically for tactical and protective gear.
How to Dry Bunker Gear: The Right Methods
1. Use Commercial Air Dryers That Meet NFPA 1851 Standards
The gold standard for drying station PPE is a commercial air dryer that complies with NFPA 1851, the standard governing the selection, care, and maintenance of structural firefighting ensembles. These systems use high-pressure ambient or low-heat air to push moisture out from seams, underarms, and vapor barrier areas that hang drying alone can never fully reach.
Key advantages of NFPA-compliant commercial dryers include the ability to dry multiple gear sets simultaneously, reach moisture-prone interior zones, maintain fabric integrity across repeated wash cycles, and support the frequent cleaning routines that help remove carcinogens from gear surfaces.
2. Turn Gear Inside Out Before Drying
Regardless of which drying method you use, always turn the gear inside out first. This exposes the interior layers where moisture accumulates most, directing airflow and dramatically speeding up drying time. It’s a simple step that makes a significant difference.
3. Separate the Shell and Liner
Disassemble your gear completely before drying. Pull the thermal liner out of the outer shell and hang each component individually. Separating the two layers roughly cuts drying time in half and ensures both components dry thoroughly, rather than trapping moisture between them.
4. Control the Temperature — Stay Below 105°F
This is non-negotiable. Heat above 105°F damages the thermal fabric, degrades moisture barriers, causes shrinkage, and can lock moisture into vapor barrier layers rather than releasing it. Whether you’re using a dryer or a cabinet system, keep the temperature at or below 105°F at all times. NFPA 1851 is explicit on this point.
5. Hang Gear on Heavy-Duty, Gear-Safe Hangers
How you hang your gear during drying matters. Standard wire or lightweight plastic hangers aren’t built for wet turnout gear — they bend, warp, and create pressure points that stress seams and distort shoulders. Use heavy-duty hangers designed for the weight of tactical and protective gear. Always check hangers and drying racks for sharp edges that could snag or puncture protective layers.

Don’t let the wrong hanger undo proper drying. Tough Hook’s RHINO Hanger is engineered for gear that works as hard as you do rated for 200 lbs, molded in the USA, and trusted by fire departments and military units nationwide.
6. Use Fans and Ventilation — Not Direct Heat
If you’re air-drying without a commercial dryer, position your gear in a shaded, well-ventilated area and use fans to circulate air over and through the components. Good airflow is the key variable. Fans provide ambient air movement without risk of heat damage, and rotating gear positions halfway through the cycle helps ensure even drying when rack space is limited.
7. Avoid Direct Sunlight
Even on a warm day, never dry bunker gear in direct sunlight. UV radiation breaks down the outer-shell fibers, compromises water-repellent treatments, and shortens the gear’s usable life. Shaded outdoor drying with good air movement is always preferable to sun exposure.
How Long Does It Take to Dry Bunker Gear?
Drying time varies significantly depending on the method:
Traditional hang drying (no airflow assist): 24–48 hours for complete gear sets.
Fan-assisted hanging: Approximately 8 hours for full gear under reasonable conditions.
PVC pipe / DIY blower systems: 8–10 hours for complete gear.
Professional ambient air dryer systems: Full gear sets in under 8 hours; heated options can bring this down to 2–4 hours.
The slower the drying method, the longer moisture sits inside vapor barriers and protective layers increasing the risk of bacterial growth and material degradation. Speed matters, especially for departments that run frequent calls.
Common Drying Mistakes to Avoid
Drying in direct sunlight. UV breaks down protective fibers and coatings faster than almost any other environmental factor.
Using excessive heat. Anything above 105°F risks thermal instability, fiber damage, shrinkage, and steam burn hazards on the next call.
Hanging gear without disassembly. Shell and liner trap moisture between them if dried together. Always separate first.
Improper machine drying. If using any mechanical dryer, follow NFPA 1851-compliant settings; overloading or using incorrect heat settings degrades materials quickly.
Skipping a complete dry. Partially dry gear that is returned to service is a health hazard. Mold, bacteria, and fungi can establish in as little as 24–48 hours in damp fabric. If you’re unsure whether gear is dry, check seams, vapor barrier edges, and wristlets these are the last areas to release moisture.
Benefits of Drying Gear Properly Every Time
Getting this right consistently pays dividends well beyond the next call. Proper drying preserves thermal insulation efficiency, maintains water repellency, prevents fabric breakdown, and significantly reduces the frequency of harsh cleaning required to remove contamination, all of which extend the service life of expensive turnout gear.
Departments that invest in proper drying infrastructure also see a measurable reduction in gear replacement costs over time. And from an operational standpoint, thoroughly dried gear is immediately ready for reuse no delays, no compromises, no gaps in readiness.

Your Gear Works Hard — Dry It as It Matters
Bunker gear is the last line of protection between a firefighter and the fire. Everything about how it’s cleaned, dried, stored, and maintained either preserves that protection or quietly erodes it. Following the steps above, proper disassembly, temperature control, airflow, and the right hanging equipment keep your gear performing at full capacity every time it’s needed.
Frequently Asked Questions
How can I tell if my gear is completely dry?
Completely dry gear feels dry to the touch in all areas, including seams, wristlets, and vapor barrier edges, carries no residual smoke smell, and weighs noticeably less than when wet. If any area still feels cool and dense, it’s retaining moisture.
Can I dry bunker gear in a small enclosed space?
No. Enclosed spaces trap moisture and prevent the airflow needed for thorough drying. This creates exactly the conditions that encourage mold growth and fabric degradation. Use a well-ventilated space or a drying cabinet designed for the purpose.
What temperature should I never exceed when drying bunker gear?
105°F is the hard ceiling set by NFPA 1851. Above this threshold, thermal fabrics, vapor barriers, and moisture barriers sustain permanent damage that isn’t visible to the naked eye but reduces protective performance.
How often should I inspect my drying equipment?
Every six months at a minimum, with documentation of each inspection. NFPA 1851 compliance requires that drying systems be maintained and functioning correctly. A malfunctioning dryer that runs too hot can silently damage the gear over multiple cycles.
What are the signs that the gear wasn’t dried properly?
Mold spots, discoloration, persistent odors, wrinkling, unusual stiffness, or any sign of moisture when the gear is handled. Hardware corrosion and seam stress can also indicate repeated under-drying over time.
