Soldering Operations at C-AD • Industrial Hygiene Study at Linac Lab 3 • Bench top soldering operations • PPE observed during study • Enclosed shoes • Long pants • Safety glasses
Building 930 Solder Operations Report, December 21, 2007 • Solder type: 60% tin and 40% lead solder • Breathing zone and source area were air-sampled • Two persons performing soldering were studied • Measurement results: • < 1% of limit for 11 metals (Cr, Cu, Pb, Ni, Ag, Sn, Zn, …) • < 1% of limit for 8 aldehydes (formaldehyde, …) • < 1% of limit for 72 terpines (ethers, benzenes, toluenes, …) • Industrial hygienist’s conclusions: • Medical surveillance not needed • Respirator not needed
Solder Waste Containers • Acceptable labels for use on solder containers: • “Contact C-A Environmental Compliance Representative at Ext. 2905 For Recycling Instructions” • “Solder Scrap For Recycling” • Label no longer used on solder containers: • “Hazardous Waste”
Safety • Not a step; not a seat either • Isn’t that exit sign lighted?
Security of Copper • Keep larger amounts of copper in a securely fenced yard or building when not in use • Copper cable should be brought to the work site in sufficient quantities for that day’s work • Decommissioned copper cable removed from buildings must be secured in a bin • Work Planner is responsible to secure copper at end of the working day
