This afternoon I had to do a filter & oil change on a big blower located in a room with 4 of them running.
Just for reference I took the thermographic camera in with me. Wall temp 47c, machine temp 78c, blowline temp 107c.
90ltrs of oil & 3 filters later I was wringing wet with sweat. All this is while wearing fireproof clothing, bump cap & hairnet, safety glasses & gloves.
I actually felt physically sick for about an hour.
Tomorrow will be worse as we are doing a roll change which takes 4 hours and is very physical, enjoy your offices.
