Safety Fuse
safety fuse[′sāf·tē ‚fyüz] (engineering) A train of black powder which is enclosed in cotton, jute yarn, and waterproofing compounds, and which burns at the rate of 2 feet (60 centimeters) per minute; it is used mainly for small-scale blasting. Safety Fuse (also Bickford fuse, blasting fuse), a fuse that transmits a heat pulse in the form of a cluster of sparks to a detonator, or blasting cap, within an exactly specified time interval. The safety fuse is covered by waterproof mastic and consists of a lightly compacted core of gunpowder grains—the powder train—that is surrounded by two layers of braided material. In the USSR, safety fuses are manufactured under the trademarks OSh-DA and OShP for underwater operations and OSh A for dry and damp operations. They range from 5 to 6 mm in diameter and burn at a rate of 10 mm per sec. safety fuseA flexible cord containing an internal burning medium by which fire is conveyed at a continuous and uniform rate for the purpose of firing blasting caps.safety fuse
