Explosion-proof foldable dual-purpose shovel

Explosion-proof tools are a special type of safety tools, mainly divided into two categories: aluminum bronze and beryllium bronze. The explosion-proof performance of the tools produced by our company complies with the national standard GB10686-89. Aluminum bronze explosion-proof tools do not cause sparks when working in an ethylene gas environment with a concentration of 7.8%; beryllium bronze explosion-proof tools do not cause sparks when working in a hydrogen gas environment with a concentration of 21%. Since beryllium bronze has zero magnetic properties, beryllium bronze explosion-proof tools are also known as anti-magnetic tools and can be used in magnetic field environments.
