I worked in a factory where spray mist coolant was used on several horizontal borers, I wouldn't have it on my machine where I stuck to flood coolant. One afternoon I walked out, the "fog" was so bad, I had irritation in my throat and upper chest. I returned the following day with a formal complaint addressed to the MD. I will give him his due he spent £10K on installing roof extractor fans, trouble was it passed through our lungs before it got to the fans!!!

Modern coolants are expected to perform a whole host of functions other than just cooling the cutting tool and the job. To this end you will find biocides, rust inhibitors etc, all of which end up being breathed in by the operator in varying degrees dependant on the accuracy of the coolant dilution rate used!! To this end we installed a premixer on the neat coolant barrel, this was checked monthly by the coolant suppliers rep. We still had one clown who thought he knew better and would enrich the mixture claiming it would not harm us.!!!!!!!!!!!

HSE take many knocks these day but on the issue of spray mist coolant listen to what they have to say also google spray mist coolant problems and see what horror stories you find. Don't wear your ear defenders you are deaf, don't wear eye protection you are blind, damage you lungs and you will end up with a nice fitting box!!
