These tools shonld not be nsed in an explosive or flammable atmosphere. 

Before nsing the tool, the worker shonld inspect it to determine that it is clean, that all moving parts operate freely, and that the barrel is free from obstrnctions. 

The tool shonld not be loaded nnless it is to be used immediately. A loaded tool should not be left nnattended, especially where it would be available to unauthorized persons. 

If a powder-actuated tool misfires, the employee should wait at least 30 seconds and then try firing it again. If it still will not fire, the user should wait another 30 seconds so that the faulty cartridge is less likely to explode, and then carefully remove the load. The bad cartridge should be put in water.
