An independent federal agency investigating chemical accidents to protect workers, the public, and the environment.
Develop and enforce corporate-directed policies and procedures which will require all DuPont facilities to audit their hot work permitting systems prior to initiating hot work to ensure that:
Revise corporate policies and procedures to require that all process piping, or similar connections to tanks or vessels be positively isolated, (using closed valves, blind flanges or pancake blanks) and the equipment appropriately vented before authorizing any hot work.
Revise corporate policies and procedures to require that the atmosphere inside the container be monitored for flammable vapor prior to performing any welding, cutting, or grinding on the container surface.
Revise corporate policies and procedures to require air monitoring for flammable vapor inside the container for the duration of the hot work consistent with industry standards (NFPA 326, NFPA 51B). Create a policy for determining criteria for requiring continuous or periodic testing for the duration of hot work.
