Info

• Before working with any particularly hazardous substance, review chemical resources for any special decontamination/deactivation procedures and ensure that you have the appropriate spill cleanup materials and absorbent on hand. • Ensure that you have the appropriate PPE, particularly gloves (check glove selection charts or call your EHSO). • Always use the minimum quantities of chemicals necessary for the experiment. If possible, try adding buffer directly to the original container and making dilutions directly. • If possible, purchase premade solutions to avoid handling powders. If you have to use powders, it is best to weigh them in a fume hood. If it is necessary to weigh outside of a fume hood (because some particles may be too light and would pose more of a hazard in turbulent airflow) wear a dust mask when weighing the chemical. It is advisable to surround the weighing area with wetted paper towels to facilitate cleanup. • As a measure of coworker protection, when weighing out dusty materials or powders, consider waiting until other coworkers have left the room to prevent possible exposure, and thoroughly clean up and decontaminate working surfaces. • Whenever possible, use secondary containment, to conduct your experiment in and to store particularly hazardous substances. • Particularly hazardous substances should be stored by themselves in clearly marked trays or containers indicating the hazard (e.g., “Carcinogens” or “Reproductive Toxins”). • Always practice good personal hygiene, especially frequent hand washing, even if wearing gloves. • If it is necessary to use a vacuum for cleaning particularly hazardous substances, use only High Efficiency Particulate Air (HEPA) filters for best capture and protection. Be aware that after cleaning up chemical powders, the vacuum bag and its contents may have to be disposed of as hazardous waste. • Ensure that information related to the experiment is included in any SOPs. 8.5 Prior Approval The OSHA Laboratory Standard requires Chemical Hygiene Plans to include information on “the circumstances under which a particular laboratory operation, procedure, or activity shall require prior approval” including “provisions for additional employee protection for work with 53
particularly hazardous substances” such as "select carcinogens," reproductive toxins, and substances which have a high degree of acute toxicity. Prior approval ensures that laboratory workers have received the proper training on the hazards of particularly hazardous substances or with new equipment, and that safety considerations have been taken into account BEFORE a new experiment begins. While your EHS Office can provide assistance in identifying circumstances when there should be prior approval before implementation of a particular laboratory operation, the ultimate responsibility of establishing prior approval procedures lies with the P.I. or laboratory supervisor. P.I.s or laboratory supervisors must identify operations or experiments that involve particularly hazardous substances (such as "select carcinogens," reproductive toxins, and substances which have a high degree of acute toxicity) and highly hazardous operations or equipment that require prior approval. They must establish the guidelines, procedures, and approval processes that would be required. This information should be documented in the laboratory's or department's SOPs. Additionally, P.I.s and laboratory supervisors are strongly encouraged to have written documentation, such as "Prior Approval" forms that are completed, signed by the laboratory worker, signed by the P.I. or laboratory supervisor, and kept on file. Examples where P.I.s or laboratory supervisors should consider requiring their laboratory workers to obtain prior approval include: • Experiments that require the use of particularly hazardous substances such as "select carcinogens," reproductive toxins, and substances that have a high degree of acute toxicity, highly toxic gases, cryogenic materials and other highly hazardous chemicals or experiments involving radioactive materials, high powered LASERs, etc. • Where a significant change is planned for the quantity of chemicals to be used for a routine experiment, such as an increase of 10% or greater than the quantity of chemicals normally used. • When a new piece of equipment is brought into the lab that requires special training in addition to the normal training provided to laboratory workers. When a laboratory worker is planning on working alone on an experiment that involves highly hazardous chemicals or operations. 8.6 Select Carcinogens A carcinogen is any substance or agent that is capable of causing cancer—the abnormal or uncontrolled growth of new cells in any part of the body in humans or animals. Most carcinogens are chronic toxins with long latency periods that can cause damage after repeated or long duration exposures and often do not have immediate apparent harmful effects. 54
