Is it safe for an electrition to carry out electical repairs outdoors during heavy downpour?

No. During a heavy downpour, he is almost certain to get water inside his voltmeter

slippery, posing a physical hazard if he attempts to ascend or descend the ladder.

Finally, his clothing is certain to become soggy and cold, leading to a severe bout

of the ague.
