GENERAL PERSONAL PROTECTIVE AND HYGENIC MEASURES; The usual precautionary measures for handling chemicals should be followed. Determine the quality and composition of fumes and gases to which workers are exposed by taking an air sample from within the brazer's helmet or in the brazers working zone. Improve ventilation if exposure limits are exceeded. Keep away from food, beverages and feed.

VENTILATION; Use enough ventilatiom , loccal exhaust at the flame or heat source, to keep the fumes and gases out of the brazer's breathing zone and general area. An approved respirator should be used unless exposure assesments are below applicable exposure limits.
