23 Biosafety Manual EH&S offers a variety of biosafety and other safety-related on-line and classroom training courses. Visit Learn @ISU for more information or to register for classes. Signs and Labeling Anyone entering areas where biohazardous materials are used must be aware of the potential hazards. Specific door signs for this purpose are provided by EH&S through the door signage app (https://ask.ehs. iastate.edu/pods) ; call (515) 294-5359 if you require assistance. A biohazard symbol with a red background indicates “human biohazards,” and must be posted at the entrance of rooms where microorganisms or biological toxins known to cause disease in humans are used. This includes microorganisms classified as Biosafety Level 2 (BSL2) or greater and human blood, tissues, cell lines, or OPIM. Red or orange biohazard labels must be placed on containers and storage units (refrigerators, freezers, incubators, waste containers, etc.) used for microorganisms or biological toxins causing disease in humans, or human blood, tissues, cell lines, or OPIM. Contaminated equipment and biohazardous waste must be labeled in the same manner. A biohazard symbol with a yellow background indicates “animal biohazards,” and must be posted at the entrance of rooms where strict animal pathogens are used. A biohazard symbol with a dark green background indicates “plant biohazards,” and must be posted at the entrance of rooms where strict plant pathogens or pests are used, or where certain Genetically Modified (GM) organisms or microorganisms are grown or processed. Where multiple biohazards are present, human hazards generally take precedence over animal and plant hazards when choosing which sign to use. To create the correct signs, go to Door Signage. The emergency contact information and minimum requirements for working in each space, shall be displayed at the laboratory entrance. The door signage must be tailored to the specific hazards in the laboratory environment. The door signage program requires a current chemical inventory. If you have questions about required signage, please contact EH&S at (515) 294-5359. To maintain compliance with OSHA’s Bloodborne Pathogen Standard, the entrance to any laboratory or area where Human Immunodeficiency Virus or Hepatitis B Virus are used or stored must have a door sign which is predominantly fluorescent orange or orange-red with lettering and symbols in a contrasting color. These signs must include the universal biohazard symbol and the word “biohazard.” These signs must include the name of the potentially infectious material, any special instructions for entering or exiting the area, and the name and telephone number of the area supervisor. These door signs may be requested from EH&S.
