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
Unmanned aircraft system (UAS) and photogrammetry software have matured together at just about the right time. This makes for possibilities that were unthinkable only a few years ago.
ERM used demo software downloaded from the Internet and images taken by a hobbyist with a Phantom 2 Vision+ UAS to create this photogrammetry video in only a few hours, learning curve included. Yeah, those are school buses. Imagine the possibilities.
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.
As part of the Section 333 exemption process, unmanned aircraft systems (UAS) used for commercial purposes must be registered with FAA before conducting operations or obtaining a COA. FAA’s information available on the Internet does not provide everything one needs to know when applying for a UAS registration.
BEC Dealer LLC, a sister company to Explosives Risk Managers LLC, has added the DJI Phantom 2 Series UAS to its product lines.
Visit BEC Dealer’s on-line store to purchase Phantom 2 series aircraft or accessories. Let us know if you can find a better retail price.
Explosives Risk Managers confirmed today that the the information posted by FAA on obtaining a civil certification of waiver authorization (COA) under Section 333 is incorrect. FAA replied to our inquiry via email…
We are in the process of updating our website. For civil COAs you need an exemption first before you can apply. Once you receive your exemption # you will then be able to submit a Civil COA.
FAA will probably fix the website soon. We just hope it takes less than 60 days to get a response from FAA on a request for a COA.
On July 14, 2014 the Office of Surface Mining and Reclamation Enforcement (OSM) announced that it had received a petition for rulemaking from the Wild Earth Guardians (WEG) to regulate NOx from blasting more rigorously and invited the public to comment.
OSM received 119 comments on the petition, many supportive. On February 20, 2015 OSM announced that it accepted the petition and would open rulemaking to “address this issue.” Continue reading
