Rooftop about 15' from edge of 4 story roof. 480 3 oh. so I dropped the main gear...tested the voltage and good to go on a 2nd stage compressor change out. Went to pull the crankcase heat and got my vision back sitting on the edge of the roof facing the unit. Bleeding and hurting terribly.
Some dim-wit wired the heater on the T side of the main gear so it was hot all the time. 277 hurts.............a lot.
Tag out lock out my friend. Not that I have always followed the rules.
The rules have gotten more strict as the years have gone down. I used to climb oily steel stories above ground to replace something without safety gear. Now our guys have to prophylactic themselves for everything.
Of course I agree with this because no one should have to go home injured or worse never make it home to the wife and kids.
