In my workplace our products are cleaned using a mixture of water and a highly alkaline cleaner as part of the manufacturing process. This cleaner is composed of sodium hydroxide, corrosion inhibitors and chelating agents. A tank is filled with this mixture of water and cleaner and is heated to 60°C where it is maintained. The products are lowered into the liquid then a lid seals the tank. Vapours are given off from the liquid. I am concerned that this vapour is harmful to the workers. My question: Does the sodium hydroxide evaporate with the water? (Therefore being inhaled by the workers)

I would refer to the MSDS of the product. NaOH normaly doesn`t evaporate, but probably the other additives.

Can you reveal what the product is made from? Is it aluminum by any chance?

While NaOH doesn't evaporate, in my experience many NaOH containing solutions easily produce caustic aerosole that can be quite nasty.

The product is called "Spraywash XHD". No it is not aluminium.
