  • Title: [Hygienic evaluation of new welding processes and welding materials].
    Author: Gorban' LN.
    Journal: Gig Tr Prof Zabol; 1990; (11):50-4. PubMed ID: 2086363.
    Abstract:
    The possibility of contaminating the breathing air zone with hazardous substances in manual and semi-automated welding increases with the intensity of their formation in the arc zone. This necessitates more comprehensive data on both the specific excreta and the formation intensity of the most hazardous substances, such as hard and gaseous compounds of welding aerosols, with due account of the welding regimen used and electrode diameter, wires, etc. When calculating the effectiveness of both local and general ventilation systems in welding shops, a possibility of a specific one-way hazardous action of some chemical substances (e.g. chromium, fluorine, etc.) should be taken into account.
