Flame-resistant (FR) clothing plays a crucial role in protecting workers from fire hazards in industries such as oil and gas, electrical utilities, and welding. Proper maintenance of FR garments is essential to preserve their protective properties and ensure their longevity. This guide provides a detailed explanation of how to wash, dry, and care for FR clothing to maintain its effectiveness and durability.
Understanding Flame-Resistant Clothing
Before diving into the washing process, it’s important to understand what makes FR clothing unique. FR garments are made from special fabrics designed to resist ignition and self-extinguish when exposed to flames. These protective properties are either inherent to the fabric or chemically treated. Proper care ensures that these features remain intact, safeguarding workers in hazardous environments.
General Guidelines for Washing FR Clothing
To maintain the protective qualities of FR clothing, follow these general guidelines:

Read the Manufacturer’s Label:

Always consult the care instructions ...
... provided by the manufacturer. These instructions are tailored to the specific fabric and treatment used in the garment.


Avoid Contaminants:

FR clothing can lose its effectiveness if contaminated with flammable substances such as oil, grease, or paint. Pre-treat stains and ensure garments are thoroughly cleaned to remove any residues.


Separate FR Clothing:

Wash FR garments separately from regular clothing to avoid cross-contamination and protect the FR properties.


Use Mild Detergents:

Select detergents that are free from bleach, fabric softeners, or strong alkalis, as these can degrade the FR properties.

Step-by-Step Washing Instructions
1. Pre-Washing Preparation:

Inspect the Garment: Check for visible stains, damages, or signs of wear. Treat stains promptly using appropriate stain removers that are compatible with FR fabrics.
Turn Inside Out: Turning garments inside out minimizes surface abrasion and extends the life of the fabric.

2. Choosing the Right Detergent:

Opt for detergents labeled as safe for FR clothing. Avoid using products with bleach, hydrogen peroxide, or fabric softeners.
Avoid homemade or untested detergents, as they may inadvertently degrade the fabric’s properties.

3. Setting the Washing Machine:

Temperature: Use warm water (around 105°F or 40°C). Hot water can damage certain FR fabrics, while cold water may not effectively remove contaminants.
Cycle: Choose a gentle or normal cycle to avoid excessive wear.
Load Size: Avoid overloading the washing machine, as this can lead to inadequate cleaning and increased fabric friction.

4. Pre-Treating Stains:

Use stain removers that are specifically recommended for FR garments. Apply the solution directly to the stain and let it sit for 5-10 minutes before washing.
Avoid harsh scrubbing, as this may damage the fabric.

5. Washing:

Load the machine with FR clothing and ensure there is enough room for water and detergent to circulate freely.
Start the washing cycle and monitor for proper agitation and rinsing.

Drying FR Clothing
Proper drying is as important as washing. Improper drying techniques can compromise the integrity of FR garments.
1. Avoid High Heat:

Use a low or medium heat setting in the dryer. High heat can damage the fabric and reduce its protective properties.

2. Air Drying:

Whenever possible, air-dry FR garments. Hang them in a shaded, well-ventilated area away from direct sunlight, which can degrade the fabric.

3. Tumble Drying:

If using a dryer, remove the garments promptly once dry to avoid wrinkles and static buildup.

Do’s and Don’ts for FR Clothing Care
Do’s:

Inspect Regularly: Regularly check for wear and tear, such as fraying or holes, which can compromise protection.
Repair Promptly: Repair or replace damaged garments immediately.
Store Properly: Store FR clothing in a clean, dry place away from flammable materials.

Don’ts:

Avoid Bleach and Softener: These chemicals can strip away FR treatments or weaken inherent FR properties.
No Ironing at High Heat: High temperatures can damage the fabric’s structure. If ironing is necessary, use a low-heat setting.
Don’t Mix Loads: Mixing FR clothing with regular laundry can introduce contaminants that reduce flame resistance.

Special Considerations for Industrial Laundering
In industrial settings, FR garments are often laundered in bulk. Ensure that the commercial laundering facility follows best practices for washing FR clothing:

Dedicated Machines: Use machines exclusively for FR garments to avoid contamination.
Specialized Detergents: Ensure the use of detergents approved for FR fabrics.
Controlled Temperatures: Maintain consistent washing and drying temperatures to prevent fabric degradation.

Removing Tough Stains from FR Clothing
Stains from grease, oil, or chemicals are common in industrial environments. Follow these steps to effectively remove tough stains without compromising FR properties:

Pre-Treat:

Apply a compatible stain remover to the affected area and let it sit for 10-15 minutes.


Soak:

Soak the garment in warm water with a mild detergent for 30 minutes before washing.


Repeat if Necessary:

For stubborn stains, repeat the process, but avoid using aggressive cleaning agents.

Frequently Asked Questions    
1. Can I use bleach on FR clothing?
No, bleach should never be used on FR clothing as it can weaken the fabric and strip away FR treatments.
2. Is it safe to dry-clean FR clothing?
Dry cleaning is generally not recommended for FR garments, as the chemicals used can reduce their flame-resistant properties. Always check the manufacturer’s guidelines.
3. How often should I wash FR clothing?
Wash FR clothing regularly to remove contaminants. The frequency depends on the work environment and exposure to dirt or flammable substances.
Extending the Life of FR Clothing
To maximize the lifespan of FR garments:

Follow care instructions meticulously.
Avoid unnecessary wear and tear by storing garments properly.
Use protective outerwear in highly abrasive environments to shield FR clothing.

When to Replace FR Clothing
Even with proper care, FR clothing will eventually wear out. Replace garments if:

The fabric is torn or frayed.
The garment no longer fits properly, affecting its coverage.
Stains or contaminants cannot be removed.
The manufacturer’s recommended lifespan has been reached.

Washing FR clothing correctly is critical to maintaining its protective features and ensuring worker safety. By following the guidelines outlined in this guide, you can extend the life of FR garments, keep them in top condition, and uphold the safety standards required in hazardous work environments. Proper care not only protects the wearer but also represents a commitment to workplace safety and compliance with industry regulations.
