GUARDING AGAINST SHOCK HAZARDS - Locked Protected Fencing

[mtnelect]

In commercial & industrial locations, I often see locked fencing protecting electrical services & equipment, required by the utilities. This might be the solution for protecting residential properties for outside condensing units. Since the Task Group formed by NFPA to solve the GFCI (Ground Fault Circuit Interrupter) problem, which will never be solved.

In some jurisdictions they already require "Screening" around outside HVAC (Heating Ventilation Air Conditioning) units.

Also, the Mechanical Code requires locked caps for refrigerants access caps.

The locked refrigerant caps are to to keep people from getting high. The newer refrigerants are poisonous, but back in the old days, huffing refrigerant was common, and grocery stores had to put fences around if the refrigeration equipment wasn’t on the roof. Wired a Sam’s Club in the early 90’s in Panama City, the HVAC guys had a heck of a time keeping the units running until they put up a fence. My cousin’s son was found dead behind a convenience store huffing refrigerant. He had just got out of college, had a high paying job lined up with the National Geographic Survey.

So sad to hear ...
