Use a biohazard warning symbol to designate labs or storage areas housing human blood, blood products, or tissues, and any pathogenic agents. If a laboratory is conducting work at BSL2 level or above, a warning sign identifying the agent, emergency contact, and any special precautions required, must be posted on the laboratory door as well. See the appendices for a summary of biosafety levels, and a listing of agents. EHS will conduct random inspections of biological laboratories. Never mouth pipette.
Thin gloves offer little protection against cuts, bites, scratches, etc.
Wearing two pairs of thinner gloves permits the safe removal of the outer pair in case of inadvertent contamination. Wear a lab coat while in the laboratory. The lab coat should be closed, and the sleeves tucked into the gloves or otherwise restrained. Disposable Tyvek lab coats are available and recommended for work conducted in biosafety cabinets. Do not wear lab coats outside of the laboratory.
