OregonLive reported that a man lost his life in an incident involving exploding targets on Mt. Hood.
Making exploding targets is an explosive manufacturing activity and should be done with utmost care. Once mixed, exploding targets are an explosive and should be transported, handled and used as any other explosive.
The Shillong Times reports that a person was “blown into pieces” following a blast of explosives at his kitchen on Friday evening in India. The authorities reported finding safety fuse in the home.
Blasters check for continuity during explosives safety training supported by ERM.
Recently, ERM assisted a client with a safety issue regarding the use of electric detonators. The client’s safety policy called for ensuring that electric detonator circuits showed “continuity” before attempting to fire the shot.
Although that is a good practice, we advised the client that a better practice would be to require measurement of the circuit resistance and comparison of that number to the expected resistance. Continue reading
The National Fire Protection Association (NFPA) and Explosives Risk Managers (ERM) reached an agreement today for ERM to update a chapter from the 20th edition of the Fire Protection Handbook; specifically Chapter 6.15 Explosives and Blasting Agents. The 20th edition was available in 2008.
The completion date for this project mid-April 2015. The publication will be available in hard copy or a new e-version from NFPA several months later.
An old discussion on radio frequency (RF) hazards on Linked In’s Blasting Professionals group resurfaced recently. Several participants have asked ERM for RF incident reports from our files, which we gladly provided.
We understand completely the desire for documentation, but it strikes us that some people may doubt whether or not an electric detonator can be initiated with RF. Uhh, let’s see here…every wireless device created by man converts radio wave energy into electricity and we’re wondering what again?
