Coating SUS304 to Reduce Burns 1

[Finglas]

Does there exist any form of coating that can reduce the prospect of burns when coming into contact with SUS304?

" burn" = thermal, chemical, saucy and exceedingly clever insult ?

Who or what is to be protected, and from what?

Temperatures involved ?

There is a type of coating called "insulation" that does prevent people from getting burned by hot objects; it also reduces the energy required to keep said objects hot.

You need two things to be burned by something: 1) it needs to be hot- typically over 60 C and 2) it needs to be able to transfer heat into your skin rapidly enough to cause your skin to rise in temperature fast enough that you are burned before you can react. Insulation deals with both 1) and 2), as long as you don't clad it- if you clad the insulation with metallic cladding, you need to keep the surface temperature of the cladding below 60 C. If you clad with an insulating material (for instance silicone impregnated glass cloth), surface temperatures can be higher without generating burns.

...Sorry, you also need a 3rd thing, which is to come in contact with the hot thing. For surfaces that are intended to LOSE heat, you prevent burns by providing a means to keep people from touching the hot thing.

I guess the insulation is a good start alright. Not sure if it will be a viable option in this case however.

Basically, it's a thermal chamber that will be connected to a TA-5000A environmental heating and cooling temperature forcing air stream system. We will be using it to heat a twin walled SUS304 chamber to about -200 deg C and -40 deg C. This will be in an interlocked enclosure which will only be able to open when it reaches a safe working temperature.

Operators will be loading and unloading product into a chamber (open chamber door - load product - close door). Mainly dangers associated with hands/arms.

You might think about thermochromic indicators (labels, paint) on handles, or other methods of indicating when the surfaces are too hot to touch?

 

[Finglas]

Great idea, hadn't thought of that. Do you have a link by any chance. I will Google it but no harm in having a recommendation.

 

[btrueblood]

omega.com, or just google thermochromic paint/pigment/labels.

Have contacted Omega in the UK. Many thanks.

There's always PPE, which is required when handling cryogenic material or just being in proximity thereto.

TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!

Yes PPE will be advised.
