The safety clamp was attached to the rigid steel coupling at the end of the flexible hose. c) On and prior to 4/30/2009, the safety clamp on the high pressure assembly located in the "mud pump" house was improperly installed. The safety clamp was attached to the rigid steel coupling at the end of the flexible hose. Among other methods, one feasible and acceptable abatement method to correct these hazards would be a) stake or place weighted objects over appropriate sections of rigid gas lines and b,c) install safety clamps in accordance with the hose manufacturer markings found on the hose assembly. Typically these markings are placed 8-12 inches inboard of the rigid steel coupling.
