Posted By Boh Aside from a sensible confined space R/A of the job, are there any guidelines, regs or ACOPs for safe temperatures to enter an oven.

Posted By Warren Fothergill Remember the most important think, is checking to see if the individual is happy to enter the environment. Within the RA you should identify safe working conditions e.g. temperature, which I would say is potentially less 30 degs C, however I have known management to say, if it were 35 degs you'd sunbathe in that heat wouldn't you? To which I have replied, yes, but the sun aint shining in here, I'm not wearing shorts and there's no air in here - yes don't forget extraction etc. PPE Regards Warren

Posted By garyh Confined space entry! Persons asking questions! Alarm bells ringing.......... Seriously never allow anyone who is not experienced and competent to manage an entry. It is not just temperature - what work will they be doing? What PPE / clothing is worn? Humidity? Cooling? Access / egress? Read the ACOP - it is excellent. Agree with above posts, never forget, the rescue arrangements. This is NOT "dial 999".

Posted By stephen d clarke Hi, In the good old days I spent some time rebricking the inside of cement clinker kilns in the 1970s. The kilns were 100s of metres long and at a slight angle, limestone slurry went in at one end and flowed down to a burner pipe at the other, the kilns were approx 12 feet in diameter. They stopped the kiln when hot spots formed on the steel outer caseing and sent us in to replace the firebricks within hours. I remember my wellies starting to melt but we were OK because of the forced air ventilation which was gale force blasting up the kiln. Steve

Posted By stephen d clarke Hi, Run for it I guess, no formal safety systems then, no one died in the kilns but someone was killed inside one of the ball mills. Steve

Posted By Juan Carlos Arias The incident a few year ago was in a travelling oven and there were loads of lack of management and poor H&S culture involved in it. You should try to find ways in how to do your intended tasks without entering the oven. if there are no ways of doing it from the outside, carry out a detail risk assessment & Safety operational procedures. 30 degrees centigrade sound the bell, I believe I read somewhere that that is a safe temperature to go in. Don't just rely on temperatures displayed on he oven itself but utilise other thermometer too. What type of oven is it? travelling, deck or rotary?
