“Blue WP” is an uncoated fuse which is exclusively used in India. In Blue WP fuse, gunpowder is wound in jute yarn and coated with a layer of bitumen. For added protection against moisture and dampness it is given an additional covering of Poly Ethylene tape and again coated with a layer of bitumen. For identification purposes and to cover the stickiness of the bitumen layer, the fuse is coated with a layer of blue colour. This product is less water resistant and is recommended for use only in dry areas.
Although every effort is made to insure uniform burn times, safety fuses are subject to variation depending on conditions and should be used with adequate safety margins.
