Section VII – Spill And Leak Procedures

Specific Steps To Be Taken In Case Material Is Released Or Spilled:

Provide Ventilation, isolate area.  Large spills require the use of self contained breathing apparatus.  He spill should be absorbed (vermiculite, sawdust, Fuller’s earth).  Pour liquid decontaminate (90% water, 8% Ammonium Hydroxide, 2% detergent) on spillage, allow to react for at least 10 minutes.  Collect in open container or polyethylene sheet, and further decontaminate liquid.  Remove container to safe place with loose cover.

Specific Waste Disposal Method:

Dispose of Material in landfill according to Federal, State and local regulations.

Section VIII – Special Protection Information

Respiratory Protection:

Self contained breathing apparatus

Local Exhaust:

Keep fresh air circulating

Protective Gloves:

Neoprene, butyl rubber, vinyl & polyethylene

Other Protective Clothing Or Equipment:

PVC apron, safety shoe.  Safety showers & eyewash should be available.

Eye Protection:

Safety goggles or glasses
