Did you know that curtains can be a fire hazard if they are not flame retardant? Flame retardant curtains are specially treated or made with fabrics that resist or slow down the spread of fire. They can help prevent a small fire from becoming a big disaster and save lives and property.

Flame retardant curtains are especially important in places where there is a high risk of fire, such as schools, hospitals, theatres, hotels, and care homes. But how can you tell if your curtains are flame retardant or not? In this post, we’ll show you how to check if your curtains meet the fire safety standards and what to do if they don’t. Follow these easy steps and you’ll be able to enjoy your curtains without worrying about fire.

How to tell if curtains are flame retardant: a simple guide to fire safety

  • To tell if curtains are flame retardant, you need to ask the manufacturer, ask for a certificate, or ask your local fire department.
  • You can also perform a small burn test on a sample of the fabric, but this is not recommended as it can damage the fabric and cause inaccurate results.
  • You can also look for labels or tags that indicate the fire rating of the fabric, such as NFPA 701, BS 5867, M1, B1, or EN 13773.

Step 1: Ask the manufacturer

The easiest way to tell if your curtains are flame retardant is to ask the manufacturer or the seller. They should know all the details about the fabric and the treatment of the curtains, including their fire rating and certification. You can also tell them your specific requirements and preferences for fire safety and they can provide you with suitable options.

Step 2: Ask for a certificate

Another way to tell if your curtains are flame retardant is to ask for a certificate from the manufacturer or the seller. A certificate is an official document that proves that the fabric has been tested and meets the fire safety standards. It should include information such as the name of the fabric, the name of the testing laboratory, the date of testing, and the results of testing. A certificate is more reliable than a test report, which may not be valid or accurate.

Step 3: Ask your local fire department

If you can’t get in touch with the manufacturer or the seller, or if you don’t trust their information, you can also ask your local fire department for help. They should know about the fire safety regulations and standards in your area and they can advise you on how to check if your curtains are flame retardant. They may also be able to inspect your curtains and test them for fire resistance.

Step 4: Perform a small burn test (not recommended)

A burn test is a method of testing the flammability of a fabric by applying a small flame to it and observing how it reacts. However, this method is not recommended for several reasons:

  • It can damage or destroy the fabric
  • It can cause inaccurate results due to different factors such as humidity, air flow, or contamination
  • It can be dangerous and cause injury or fire

If you decide to perform a burn test anyway, make sure you do it in a safe and controlled environment with proper precautions. Here’s how:

  • Cut a small sample of the fabric (about 2 inches by 2 inches) from an inconspicuous area of the curtain
  • Use tweezers or pliers to hold the sample over a non-flammable surface such as a metal tray
  • Use a lighter or a match to light one corner of the sample
  • Observe how the sample burns, melts, smokes, smells, and chars
  • Compare your observations with this table:
Fabric Burning Melting Smoking Smelling Charring
Cotton Burns quickly with yellow flame Does not melt Produces black smoke Smells like burning paper Leaves soft gray ash
Linen Burns quickly with yellow flame Does not melt Produces black smoke Smells like burning paper Leaves soft gray ash
Silk Burns slowly with yellow flame Does not melt Produces black smoke Smells like burning hair Leaves brittle black ash
Wool Burns slowly with orange flame Does not melt Produces dark smoke Smells like burning hair Leaves brittle black ash
Polyester Burns slowly with orange flame Melts and drips Produces black smoke Smells like burning plastic Leaves hard black bead
Nylon Burns slowly with blue flame Melts and drips Produces white smoke Smells like burning plastic Leaves hard gray bead
Acrylic Burns quickly with yellow flame Melts and drips Produces black smoke Smells like burning plastic Leaves hard black bead

In general, natural fabrics such as cotton, linen, silk, and wool are more flammable than synthetic fabrics such as polyester, nylon, and acrylic. However, some natural fabrics may be treated with flame retardant chemicals to make them more resistant to fire. Some synthetic fabrics may also be blended with natural fibers to make them more comfortable and breathable. Therefore, a burn test may not be conclusive or reliable.

Step 5: Look for labels or tags

Another way to tell if your curtains are flame retardant is to look for labels or tags that indicate the fire rating of the fabric. There are different fire rating systems in different countries and regions, but some of the most common ones are:

  • NFPA 701: The National Fire Protection Association (NFPA) standard for flame propagation of textiles and films in the United States. It tests how a fabric burns when exposed to a large flame in a controlled chamber. It has two classes: Class 1 for fabrics that pass the test and Class 2 for fabrics that fail the test.
  • BS 5867: The British standard for fabrics for curtains and drapes in the United Kingdom. It tests how a fabric burns when exposed to a small flame in a vertical position. It has three parts: Part 2 Type A for non-durable flame retardant fabrics, Part 2 Type B for durable flame retardant fabrics, and Part 2 Type C for inherently flame retardant fabrics.
  • M1: The French standard for reaction to fire of building materials and furnishings. It tests how a fabric burns when exposed to a radiant heat source and a small flame in a horizontal position. It has five classes: M0 for non-combustible materials, M1 for non-flammable materials, M2 for hardly flammable materials, M3 for moderately flammable materials, and M4 for easily flammable materials.
  • B1: The German standard for reaction to fire of building materials and furnishings. It tests how a fabric burns when exposed to a radiant heat source and a small flame in a vertical position. It has five classes: A1 for non-combustible materials, A2 for hardly combustible materials, B1 for flame retardant materials, B2 for normally flammable materials, and B3 for easily flammable materials.
  • EN 13773: The European standard for classification of reaction to fire performance of curtains and drapes. It tests how a fabric burns when exposed to a small flame in a vertical position. It has three classes: Class 1 for fabrics that have limited contribution to fire, Class 2 for fabrics that have acceptable contribution to fire, and Class 3 for fabrics that have significant contribution to fire.

If you find any of these labels or tags on your curtains, you can tell if they are flame retardant or not by checking their class or type. The higher the class or type, the more flame retardant the fabric is.
