This list is not exhaustive; consult the material safety data sheet to determine whether a particular chemical may be considered a carcinogen, reproductive hazard or substance with a high acute toxicity. A chemical is considered a carcinogen, for the purpose of the Laboratory Safety Manual, if it is included in any of the following carcinogen lists:. The following steps must be taken:.
Information required on the form includes:. The area where the PHS will be used is posted as a designated area. Signs for this purpose are available through EHS or may be made by the department or laboratory worker, as long as it includes the following information:.
The laboratory worker proceeds with the experiment, following the practices outlined in the Particularly Hazardous Substance Use Approval form, as well as the appropriate work practices included in the remainder of the Safe Work Practices and Procedures section of this manual. Peroxide formation may be detected by visual inspection for crystalline solids or viscous liquids, or by using chemical methods or specialized kits for quantitative or qualitative analysis.
If you suspect that peroxides have formed, do not open the container to test since peroxides deposited on the threads of the cap could detonate. See Anecdotes for an account of an incident in our laboratories involving peroxide detonation. If there is any suspicion that peroxide is present, do not open the container or otherwise disturb the contents.
Call EHS for disposal. The container and its contents must be handled with extreme care. If solids, especially crystals, for example, are observed either in the liquid or around the cap, peroxides are most likely present. If no peroxide is suspected but the chemical is a peroxide former, the chemical can be tested by the lab to ensure no peroxide has formed.
Peroxide test strips, which change color to indicate the presence of peroxides, may be purchased through most laboratory reagent distributors. Do not perform a peroxide test on outdated materials that potentially have dangerous levels of peroxide formation. If peroxides are suspected, the safest route is to alert EHS for treatment and disposal of the material.
Attempting to remove peroxides may be very dangerous under some conditions.
