guidelines rather than as fine lines between safe and dangerous concentrations. The best way to avoid exposure to toxic vapors, mists, gases, and dusts is to prevent the escape of such materials into the working atmosphere and to ensure adequate ventilation by the use of exhaust hoods and other local ventilation. Avoid Exposure: Know the safety rules and procedures that apply to the work that is being done. Determine the potential hazards (e.g., physical, chemical, biological) and appropriate safety precautions before beginning any new operation. Know the location of and how to use the emergency equipment in your area, as well as how to obtain additional help in an emergency, and be familiar with emergency procedures. Know the types of protective equipment available and use the proper type for each job. Be alert to unsafe conditions and actions and call attention to them so that corrections can be made as soon as possible. Someone else’s accident can be as dangerous to you as any you might have. Do not consume or store food or beverages or smoke in areas where chemicals are being used or stored. General Requirements Employee Exposure Determination Initial Monitoring The Department of Environmental Health and Safety will measure an employee’s exposure to any substance regulated by a standard which requires monitoring if there is reason to believe that exposure levels for that substance routinely exceed the action level (or in the absence of an action level, the permissible exposure level). Periodic Monitoring If the initial monitoring discloses employee exposure over the action level (or in the absence of any action level, the PEL), the exposure monitoring provisions of the relevant standard will be followed. Termination of Monitoring Monitoring may be terminated in accordance with the relevant standard. Employee Notification of Monitoring A copy of the results of such monitoring will be sent to the employee or employees involved (or posted in an appropriate location near the area tested) within 15 days of receipt of the test results. The Office of Environmental Health and Safety will maintain an official record of the results.

Polypropylene lab coat. Various models available from VWR through ECAT. Ex: VWR Cat. #414004- 346 No. No. Breathable Intended for protection from dirt, grime, dry particulates in relatively hazardous environment such as animal handling and clean rooms. Burns readily. VWR Microbreathe Lab Coat Available from VWR through ECAT VWR cat. Fluid resistant for blood and body fluids and chemicals No Breathable Disposable. For clinical and biological lab settings, and some chemical labs. Snap front, so can be readily removed. Not good for settings with significant fire hazard. Kimberley Clark A65 Lab Coat (Disposable FR Coat) Available from VWR through ECAT. No Information. Yes. Breathable Product literature mentions lab use. Reusable Fluid Resistant Coats Supplier: Cintas Manufacturer: White Knight Model: BAR 01 Supplier: North Star Manufacturer: Fashion Seal Model: 6403 Front material reportedly fluid resistant; “breathable” back material is not. No Permeable material in back of coat to increase comfort. Generally the front and sleeves are “fluid resistant” material, while the back is a more permeable material for user comfort.
