< Back

December 2004

ASSE, as secretariat of the A10 ANSI Accredited Standards Committee (ASC) for Construction and Demolition Operations, has continued to receive a number of inquiries related to the ANSI/ASSE A10.7-1998 American National Standard Commercial Explosives and Blasting Agents – Safety Requirements for Transportation, Storage, Handling, and Use.

Due to these inquiries, we have put together “guide” for those with interest.

Title: Commercial Explosives and Blasting Agents – Safety Requirements for Transportation, Storage, Handling, and Use.

Past Versions of the Standard:

A10.7-1970

Current Status of the A10.7-1998 Standard: Committee work continues to move forward on a revision of the standard. There is not yet any estimated time for committee ballot and public review.
