HAZARD IDENTIFICATION DEFINITIONS:
| Biohazard | A non-specific biohazard. This I.D. should be used in areas where there are multiple non-specific biological hazards and areas where biological wastes are stored. |
| Biohazard – Potentially infectious materials | This warning should be used for areas where human body fluids, unfixed cell tissue or organ cultures are handled for research, diagnosis, or shipment. |
| Biosafety Level 2 | A specific warning which designates a containment level which meets BMBL recommendations for BSL 2 work practices, safety equipment and facility design. |
| Animal Biosafety Level 2 | A specific warning which designates a containment level which meets BMBL recommendations for ABSL 2 work practices, safety equipment and facility design |
| Biosafety Level 2 (Enhanced) | Designates a BSL2 facility in which special work practices (the additional work practices required for BSL3) are required |
| Biosafety Level 3 | A specific warning which designates a containment level which meets BMBL recommendations for BSL3 work practices, safety equipment and facility design |
| Cancer Suspect Agent | This warning should be used for areas that use or store chemicals classified by IARC or NTP as known or suspected human of known animal carcinogens |
| Cancer Hazard | This warning should be used for areas which contain chemicals that are specifically regulated by OSHA as carcinogens |
| Chemical Storage Area | This warning should be used for areas such as: chemical stockrooms or storage rooms utilized by more than one researcher specifically for chemical storage |
| Corrosive Materials | This warning should be used for areas containing chemical substances capable of damaging human tissues |
| Flammable Materials | This warning should be used for areas that are regularly used to store any of the following:
· 1 gallon or more of a class 1 (A liquid having a flashpoint below 100F) or class 2 (A liquid having a flashpoint between 100F and 140F) flammable liquid outside a flammables storage cabinet. · 5 gallons or more of a class 3A (A liquid having a flashpoint between 140F and 200F) flammable liquid outside a flammables storage cabinet · Any quantity of flammable gas · Any quantity of flammable solid · Any quantity of water or air reactive solids
|
| Electrical Hazard | This warning should be used for areas which contain accessible equipment with exposed and unguarded electrical components operating at less than 600 volts |
| ELF/EMF Hazard | This warning should be used for areas which contain equipment capable of generating an electrical field of 10kV/m or more or a magnetic field of 0.5 mT or more |
| Microwave Radiation | This warning should be used for areas in which there is a potential for personal exposure to microwave radiation (frequency of 300 MHz to 30 GHz) in excess of 10 mW/cm2 |
| Laser Radiation | This warning should be used for areas in which class 2,3, or 4 lasers are used |
| Eye protection required | This warning should be used for all areas where there is a reasonable probability of exposure to hazardous chemicals, potentially-infectious agents or physical hazards which could result in injury if eye protection is not used |
| Hearing protection required | This warning should be used for areas where there is potential for noise exposure at or above 85dBA |
| Protective Clothing Required | This warning should be used for areas where there is a reasonable probability of exposure to hazardous chemicals and areas where protective clothing beyond a standard lab coat is required. Identify on the form the type of clothing required. |
| No food or drink | This warning should be used for areas in which food and drink are not to be present and/or consumed |
| Restricted Area | This warning should be used for areas that require special permission and/or an escort from the PI/lab supervisor to enter. Identify on the form the procedure required for entry. |
| Toxic Gas | This warning should be used for areas containing gases classified by the Department of Transportation (DOT) as poisonous, or by the EPA as acutely toxic. e.g. Arsine, Boron Trichloride, Methyl Mercaptan, Sulfur Dioxide, Hydrogen Flouride, Hydrogen Sulfide, Phosgene, Phosphine, etc. |
| Toxic Chemicals | This warning should be used for areas containing chemical substances defined by DOT as poisonous, by the EPA as acutely toxic, or by OSHA as Toxic or Highly Toxic |
| Water Reactive Materials | This warning should be used for areas containing any quantity of water reactive material |
| Pyrophoric Materials | This warning should be used for areas containing any quantity of pyrophoric materials (e.g. t-butyl lithium, silane, etc.) |
