Title Health problems arising out of the use of cutting fluids and coolants in industry
Original title Hygienická problematika chladidích a řezných kapalin v průmyslu [in Czech]
Bibliographic information May 1975, Vol.20, No.4, p.194-201. 3 ref.
Abstract Results of mycological and bacterial tests carried out on 103 samples of cutting fluids or coolants, before and after use. Results showed that 69% of fluids directly sampled from machine tools were contaminated. Mean concentration of microorganisms in used fluids was 8,483,666/ml. The following species of microorganisms were identified: Escherichia coli, Alcaligenes faecalis, Proteus, Candida krusei, etc. No relation was established between level of contamination and pH. Even the water used for the preparation of emulsions often failed to meet hygienic standards. Remedial measures proposed include improved machine design (easier maintenance), inspection and control of quality and grade of cutting fluids and good housekeeping.
