It sometimes makes me wonder how some of survived the laxity of safety protocols in some of the work environments some of us encountered through out our lives.
many times while working as a call out portable welding contractor on oil rigs I would notice there might not even be a blow out preventer under the substructure in a known area where high pressure gas and or oil deposits were prevalent, or even worse faulty or even no poisonous gas detectors let alone automatic emergency shut down and warning systems.
Once while adding a down hole system made by TOTCo to check the bore hole for vertical or angular directional drilling the drilling crew was tripping back in the hole once they completed their bit change and powered up the mud pump a pin hole leak had developed in the rotary swivel spraying out a 5000 PSI knife like spray of the drilling mud which struck the derrick hand still on the monkey board the spray very nearly severed his left arm. Only his quick thinking saved his arm and possibly his life but his action at the same time very nearly killed him. He grabbed the Geronimo bar with 1 hand without taking time to attach his tether line then jumped off the platform ridding the safety escape line to the ground a few hundred feet from the rig holding on by only 1 hand he could not control the decent brake and hit the end of the line quite hard. They wrapped and packed his arm in ice then rushed him to the hospital some 70 miles away in the tool pusher's pickup. His arm was saved but never completely useful
