(1) You must keep employees who are not involved in opening drums or containers a safe distance from the opening area.

(2) You must use appropriate shielding between the employee and the drums or containers, when excess interior pressure cannot be relieved from a remote location.

(3) You must provide an explosion-resistant barrier that does not interfere with the work to protect employees working near or adjacent to drum or container opening operations from accidental explosions.

(4) You must position controls for drum or container opening equipment, monitoring equipment, and fire suppression equipment behind the explosion-resistant barrier. Prohibit employees from standing on or working from drums or containers.
