ABATEMENT NOTE: Among other methods, feasible and acceptable methods to correct the conditions are to comply with applicable requirements noted in NFPA 44 which requires test samples of actual process conditions on all thermite reaction and all metal powders. NFPA 4.2.8 which states "methods of explosion protection using containment, venting and suppression protect the specific process equipment on which they are installed. Flame fronts from a deflagration can propagate through connection ductwork to other unprotected equipment. Isolation techniques can be used to prevent the propagation of the deflagration by arresting the flame front.
