In Blue WP safety fuse, gunpowder is wound in yarn and coated with multiple layers of bitumen. For added water-resistance, it is given an additional covering of plastic film. For identification purposes and to reduce the stickiness of the bitumen layer, this type of fuse is painted blue.
Safety fuse Blue WP is an economical option that is less water-resistant, and should only be used in dry conditions.

FAQs - Blue WP Safety Fuse Product
The length of the safety fuse is chosen and cut according to the required time delay. An end of the safety fuse is inserted and crimped into the plain detonator, while the other end is left open for ignition. A safety match or igniter is used to ignite the open end, and the fuse slowly burns towards the plain detonator. The slow burning gives the blaster time to retreat a safe distance from the blast site. Once the fire in the safety fuse reaches the plain detonator, the detonator explodes and initiates the explosives with which the plain detonator is used.
Safety fuse is generally used for Blasting purposes in mining, quarries and construction work with plain detonators although time fuse is somewhat similar to safety fuse and still used for fireworks.
Visco fuse / micro cord / cannon fuse is used to ignite fireworks and other pyrotechnics. They have different characteristics and usage should be evaluated thoroughly.
Outside India – An order quantity below 100 Kilometers (100,000 metres) is rarely economical due the fixed export and freight overheads. However, we can consider a lower quantity in case of specialized products and in case the buyer is agreeable to higher costs.
FAQs - Transport & Shipping
For international transport to Europe and Africa and Southeast Asia, we can send containerized shipment by sea to certain countries / ports which handle HAZ cargo and onwards transportation can take place by road as per local laws and norms. We can also air freight to many countries / airports subject to local approvals and acceptance by airlines.
Due to lengthy process of licensing, permissions and transit permits and infrequent availability of IMO vessels and congestions, even after production it may take around 15-25 days for the shipment to move from India.
