Could someone point me in the right direction. A client has asked me what temperature is safe to work on cooled furnaces and associated piping. He thinks he saw something state 50 degrees fahrenheit/10 degrees celsius. With PPE I'm sure it will differ. Does anyone know whether there is such a guideline? The client services/maintains sewerage furnaces.

In the oil industry we have past had people working inside cooling heat exchangers fixings fans where the internal temperature had still been over 50 Deg C.
I guess it depends on what your mean by safe? Prevention from scalding from touching hot surfaces? Protection from heat exhaustion? or any other or combination of hazards.
In this situation we had guys working in rotation 4 guys in 4 waiting outside, suplied with cool drinking water doing a 20 min rotation with 20 mins rest outside in the cool per hour. PPE can make it seem hotter in there than you think, but gloves and nomex/ fire proof overalls can protect against burns to some degree.
Guess the question should be, Why do they have to work inside whilst it is still that hot?

Hi,
is 10 degrees considered to be "hot"?
I would suggest that no work is done until a safe temp has been reached and would agree with last response....rotate work parties and a plentiful supply of drinking water.
