Fuse, non-detonating, is a manufactured article consisting of pyrotechnic composition in textile or plastic tubing, designed to transmit fire to connected explosive charges. It poses a significant fire and deflagration hazard, and its improper use can lead to severe consequences.

Hazard overview: The substance poses a fire and deflagration hazard, and its burning rate can be unpredictable if damaged. It is essential to exercise extreme caution when handling this material, as it can be highly unstable and sensitive to heat and shock.

Response guidance: In the event of an emergency, it is crucial to maintain a safe distance from the substance and evacuate the area immediately. Firefighters should approach the scene with caution, wearing Level B minimum protective gear, including SCBA, and full protective clothing, and maintain maximum distance during fire.
