The All American Five

With respect to comtempt of safety, if what we read about the Glenfell tower fire then if it was caused by an exploding fridge then the use of isobutane as a refrigeration gas is contempt of safety!!!!!!
There are around 5 deaths every year due to people having their heads planted on a mobile phone screen and not aware of their surroundings, more die through stupidity than got a fatal belt off a live chassis telly.

Interesting! Years ago I worked with a chemical engineer who designed a car air conditioner system that used ammonia as the refrigerate. Using the heat from the exhaust system to perculate the ammonia would not require power like a compressor does. He couldn't get approval for the design because of safety issues. What if the car crashed, pinned the passengers and the ammonia leaked into the passenger compartment? At the time I wondered if the same could not happen with the freon system. Would breathing freon be ok? The advantage of ammonia over isobutane is it will not burn.

A man leaving work was talking to his wife on his cell phone as he put the key in the door to unlock it lightening struck the phone or the car (the CB radio whip on the bumper I think). It was fatal. The company had outlawed cell phones and said he was in violation of the policy. When that was seen as accepting liability they reversed their stand and said her had clocked out and was on his own time. The lawyers argued he was still on company property etc.

I think liability lawyers influence the safety rules to much these days. ( in the States ) I've worked in plants with 5 Kv terminal exposed inside motor control centers. When someone came to the shop to complain about the exposed hazards. My boss would ask "and just how did you get into my power center?". The doors were locked and there was a sign stating only qualified electricians were allow in the center.
Lack of common sense doesn't help either. The new engineer was planning a control center extension.  He had a new room built beside the old one. There were power panels mounted on the I beams outside the old center. He had the new center built against the I beams. Sandwiching the panel between the two buildings. When I needed access and couldn't get to the panel boss called him over to discuss the matter. He had his construction crew cut access panels in the wall of his shiny new center. Imagine reaching through a hole in the wall to access a panel mounted perpendicular to the wall with the access door hinged so it swings away from the panel! He got a attaboy and promotion. The guy was maintenance superintendent when I left the job.
We would remove the covers from the 5Kv distribution gear and check the load on the circuits. The same guy declared we couldn't work hot circuits anymore. It was entertaining watching boss trying to get him to tell us how we check the load balance on a running powerhouse without working it hot. His plan was kill power, install the amp probe, restore power, repeat on all three phases. He finally got the idea that killing power meant shutting down the complex and the reading would be useless when there was a shutdown and restart between reading.
The same guy had us cover the 5Kv terminals which lead to the screw going into a hot 5 Kv lead while reinstalling a cover but that's another story. Shortly after that I left the job.
