chemical fume hood for all work involving the handling of open chemicals (e.g., preparing solutions) whenever possible. If a chemical fume hood is required or recommended to be used, the following guidelines must be followed at all times: Chemical fume hoods must be marked to indicate the proper sash position for optimum hood performance as illustrated in Figure 4.1. The chemical fume hood sash should be positioned at this height whenever working with hazardous chemicals that could generate toxic aerosols, gases, or vapors. In general, the sash height should be set at a level where the operator is shielded to some degree from any splashes, explosions, or other violent reactions which could occur and where optimum air flow dynamics are achieved. Most chemical fume hoods are not intended to be used with the sash fully open. The sash should only be fully opened to add or remove equipment from the chemical fume hood. Figure 4.1 – Chemical Fume Hood Sash Approved Working Height Chemical fume hoods must be equipped with a continuous reading monitoring device to indicate adequacy of flow. All lab employees must know how to read and interpret this gauge and check that the chemical fume hood is operating properly before using hazardous chemicals in the fume hood. There are many different types of chemical fume hoods on campus, so it is important that the lab employee understands the specific functions of each chemical fume hood used. Only apparatus and chemicals essential to the specific procedure or process should be placed in the chemical fume hood. Extraneous materials from previous experiments should be removed and stored in a safe location outside the chemical fume hood. Chemical fume hoods used for experimental work should not be used for chemical or material storage. Chemical fume hoods used for chemical storage should be dedicated to chemical storage. No experimental work should be conducted in storage chemical fume hoods. All chemical containers used in chemical fume including secondary containers (e.g., beakers, flasks, reaction vessels, vials, etc.) must be labeled. If is not practical to label a secondary container that is in process (e.g., reaction vessel, flask), a temporary label can be used as shown in Section 5.7 of the CHP. Reaction vessels in chemical fume hoods must be labeled as well. If labeling the vessel itself is not practical, the hood sash or wall may be labeled as illustrated in Figure 4.2.
Chemical Spill Dial 911 Immediately evacuate area and ensure others are aware of the spill. If there is an imminent threat of a fire, pull the nearest fire alarm station to evacuate the building and dial 911. If the spill is minor and does not pose a threat to personnel, contact REM at 49-40121 during normal business hours (7 AM – 4 PM) for spill cleanup assistance (dial 911 if spill occurs after hours and assistance is needed). Chemical Spill on Body or Clothes: Remove clothing and body thoroughly in emergency shower for at least 15 minutes. Seek medical attention; dial 911. Chemical Splash into Eyes: Immediately rinse eyes and inner surface of eyelid with water from the emergency eyewash station for 15 minutes by forcibly holding the eye open. Seek medical attention; dial 911. Section 10 – Medical Emergency Life Threatening Emergency, After Hours, Weekends And Holidays: Dial 911 Non-Life Threatening Emergency: Immediately report injury to supervisor and complete the Report of Injury. () Section 11 – Disposal Procedures Waste: Make sure the container(s) is properly labeled; label should indicate all of the contents of the container. REM provides hazardous waste labels free of charge, call 49-40121 to obtain labels. Store Waste: Store hazardous waste in closed containers, and in a designated area (flammable cabinet is recommended). Dispose of Waste:

Bromine compounds can also be used for water treatments, as a gasoline additive, in pesticides, in photographic chemicals, and in the manufacture of pharmaceuticals.
Gloves must be worn. Use proper removal technique to avoid any skin contact. Nitrile and latex disposable gloves are NOT suitable. Polyvinyl Acetate, Viton, or fluorinated rubber gloves are recommended. Check the resources below for a more suitable glove. NOTE: Consult with your preferred glove manufacturer to ensure that the gloves you plan on using are compatible with chloroform. Refer to glove selection chart from the links below: OR OR Eye Protection: ANSI approved properly fitting safety glasses or chemical splash goggles. Face shield is also recommended if there is a high probability of a splash hazard. Skin and Body Protection: Lab coats (100% cotton) must be worn and be appropriately sized for the individual and buttoned to their full length. Laboratory coat sleeves must be of sufficient length to prevent skin exposure while wearing gloves. Personnel must also wear full length pants, or equivalent, and close-toed shoes. Full length pants and close-toed shoes must be worn at all times by all individuals that are occupying the laboratory area. The area of skin between the shoe and ankle must not be exposed. Hygiene Measures: Wash thoroughly and immediately after handling. Remove any contaminated clothing and wash before reuse. Section 6 – Engineering Controls Use of Chloroform must be conducted in a properly functioning chemical fume hood. The chemical fume hood must be approved and certified by REM and have a face velocity between 85 – 125 feet per minute. Section 7 – First Aid Procedures If inhaled:
