Standard Specification for Cooking Fire Suppression Blankets
ABSTRACT
This specification covers the physical and performance requirements for fire suppression blankets used to extinguish accidental fires that occur during cooking. This specification, however, does not apply to cooking fire suppression blankets that: are made from asbestos; have sides of differing appearance, finish or color; have a performance that differs according to which side is used; or are of metallic construction or component. The blankets shall adhere to physical requirements as to size and shape, mass, hand holding devices, appearance and bi-lateral use, and resistance to fraying or tearing. The blankets should also pass tests for flexibility, ease of removal, electrical resistance, and fire performance.
SCOPE
1.1 This specification covers requirements for cooking fire suppression blankets to extinguish accidental cooking fires.
1.2 This specification does not apply to cooking fire suppression blankets that: are made from asbestos; have sides of differing appearance, finish or color; have a performance that differs according to which side is used; or, are of metallic construction or component.
1.3 The values stated in SI units are to be regarded as the standard.
1.4 The following safety hazards caveat pertains only to the test methods portion of this specification, Section 4: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
