Does "Subpart U - Blasting and the Use of Explosives" Apply to You?

Subpart U applies to blasting and using explosives. Are your employees engaged in blasting or the use of explosives? If yes, then this subpart applies to you. The definitions applicable to the subpart provide key definitions such as:

Blasting agent  -  Any material or mixture consisting of a fuel and oxidizer used for blasting, but not classified an explosive and in which none of the ingredients is classified as an explosive provided the furnished (mixed) product cannot be detonated with a No. 8 test blasting cap when confined.
