Our California State Fire Marshal Approved Fire Safety Blanket is built specifically for fire flow arts using 100% densely woven wool selected for fire safety applications. The material is inherently flame resistant without relying on added flame-retardant chemicals and is approved for use by the California State Fire Marshal.
Each blanket measures approximately 2 x 3 ft (61 x 91 cm) and weighs approximately 15 oz (425 g). The dense wool construction creates a substantial safety blanket for extinguishing fire props while remaining compact enough to keep nearby during practice, performances, and fire jams.
Inherently Flame Resistant
Unlike fabrics that depend on an applied flame-retardant treatment, the flame resistance of this material is inherent to the material itself. There are no added flame-retardant chemicals that need to remain on the surface for the material to maintain its rated flame-resistant properties.
This also means the flame resistance does not simply wash out if the material gets wet or is cleaned. For fire performers who regularly use their safety equipment outdoors, around fuel, and in less-than-pristine environments, that’s a pretty useful distinction.
California State Fire Marshal Approved Material
The material used to construct these blankets is approved for use by the California State Fire Marshal. It is classified as an inherently flame-resistant material, meaning its flame resistance is a property of the material rather than the result of an applied chemical flame-retardant treatment.
For professional performers, venues, and event organizers that require documented fire-resistant safety equipment, the CSFM approval provides a verifiable reference for the material used to construct the blanket.
Dense 100% Wool Construction
These blankets are made from densely woven 100% wool and are substantially heavier and thicker than many lightweight fabrics commonly used as fire safety blankets in the flow arts community.
Many performers casually refer to any black fire safety cloth as a “duvetyne,” but this blanket is not made from duvetyne. We chose a dense wool material specifically because it provides inherent flame resistance without depending on an applied flame-retardant chemical treatment.
Made for Fire Flow Arts
A fire safety blanket is one of the basic pieces of safety equipment that should be present whenever practicing or performing with fire props. It can be used to smother and extinguish wicks after a burn without introducing water to the prop.
The 2 x 3 ft (61 x 91 cm) size provides enough material for extinguishing common flow props while remaining manageable for a trained fire safety to handle quickly.
For more information on setting up a responsible fire practice, read our Fire Safety for Flow Arts guide. Please also review our Safety Disclaimer before working with fire props.
Cleaning & Care
The inherent flame resistance of the wool does not wash out, but that does not mean the blanket is maintenance-free. Dust, oils, fuel residue, and other contaminants can accumulate in the material and may reduce its flame-resistant performance over time.
For routine cleaning, we generally recommend keeping things simple. If needed, the blanket can be rinsed outdoors and allowed to air dry completely. This can be particularly practical for a blanket that has accumulated soot or residue from extinguishing fueled props and keeps that mess out of your washing machine.
Repeated washing can also contribute to normal physical wear, so there is little reason to wash the blanket unnecessarily. Regularly inspect your safety blanket for contamination, excessive wear, holes, thinning, or other damage, and replace it if its condition makes you question whether it is still suitable for fire safety use.
As with all fire safety equipment, proper equipment is only one part of the equation. A fire safety blanket should be readily accessible during fire practice and used by someone familiar with safely extinguishing fire props.
