Specific Decontamination Procedures <strong>for</strong> Equipment and Bench top Surfaces which have come into<br />
contact with Highly Toxic Waste<br />
Include here methods <strong>of</strong> cleaning up work surfaces in hoods or bench tops so as to render traces <strong>of</strong><br />
toxic chemicals benign.<br />
Benches will be monitored after each use <strong>of</strong> radioactive materials and weekly by smear test and hand-held<br />
counter, as specified in the user’s license. Any surfaces with contamination greater than twice background<br />
will be cleaned with soap and water or commercial cleaner as necessary. Decontamination will proceed<br />
until smear tests are at background.<br />
Benches that are contaminated with low concentrations <strong>of</strong> ethidium bromide will be cleaned with paper<br />
towels (soaked with bleach (Sodium hypochlorite) that will then be disposed <strong>of</strong> with the solid (gel) waste.<br />
In the event <strong>of</strong> a spill <strong>of</strong> high concentration ethidium bromide, the surface will be decontaminated with a<br />
slurry <strong>of</strong> activated charcoal.<br />
