team,

has anyone seen personnel protection insulation for temperatures less than 14 F? i've seen it for temperatures above 160 F for hot service.

If there is a real personnel hazard then it is the responsible thing to take some measures to protect workers. Personnel rarely can touch bare lines at very low temperatures even if they wanted to do so. If the line is inadequately insulated, ice forms on the line from air humidity. So the ice will build up quickly until the surface temperature will be closer to 32 F. Ice buildup and external condensation can be a problem for personnel due to wet ground or ice balls falling on heads. So insulate very cold lines for several reasons, but this is not considered a personnel protection scenario like hot surface temperatures would be. In extremely cold climates, workers should be wearing gloves and coats when working outdoors to avoid skin contact with any cold metal objects.

How much less than 14 F?

 

For such low temperatures, if ambient temperature isn't subzero, cold insulation is to be applied....
