[Toxic substances from the use of coolant lubricants].

The results from gas-mass analysis of the mixture of products from evaporation and volatile products from thermo-oxidizing destruction, eliminated at using lubricating-condensing devices point out, that the evaluation of the toxico-chemical factor concerning only the lubricated aerosol contact is extremely insufficient. The presence of hydrocarbons of different homologs, oxygen and nitrogen derivatives of hydrocarbons has to be taken into consideration. For correct characterization of the conditions of work and risk for the workers of these productions, creating conditions for destructive processes with lubricating oils, is necessary a standardization of the leading components of the vapour-gas phase in the air of the working environment.
