Name: Signature: Environmental Health and Safety, Box 354400 UW Environmental Health and Safety Title: Date: *to be filled in by PI or Supervisor Page D-6 February 2007 Appendix D – Example Standard Operating Procedures Laboratory Safety Manual Additional Information about Benzene Exposure Limits as Set by the Washington State Department of Labor & Industries (at WAC 296849): 8-hour Permissible Exposure Limit (PEL): 15-minute Short Term Exposure Limit (STEL): 8-hour Action Level (AL): 1.0 ppm 5.0 ppm 0.5 ppm Hazards: Benzene liquid is highly flammable. It should be stored in tightly closed containers in a cool, well ventilated area. Benzene vapor may form explosive mixtures in air. All sources of ignition must be controlled. Use non-sparking tools when opening or closing benzene containers. Fire extinguishers, where provided, must be readily available. Know where they are located and how to operate them. Smoking is prohibited in areas where benzene is used or stored. Benzene can affect your health if inhaled, if it contacts skin or eyes, or if ingested. The most frequent work place route of entry is by inhalation, but benzene can be absorbed through the intact skin and will be absorbed faster through abraded skin. High, short-term (acute) exposures may result in feelings of breathlessness, irritability, euphoria, giddiness, or irritation of the eyes, nose or respiratory tract. Also, headache, dizziness and feelings of nausea or intoxication may occur. Severe exposures may lead to convulsions and loss of consciousness. Periodic exposures at lower levels (chronic exposures) may result in various blood disorders, ranging from anemia to leukemia (an irreversible, fatal disease). Many blood disorders associated with benzene exposure may occur without symptoms. Exposure Monitoring The supervisor must determine by breathing zone air monitoring if employees are over the AL or STEL. If levels are below the AL and STEL, no further air sampling is required unless procedures change. Affected employees must be informed of air monitoring results within 15 days of the supervisor receiving the results. Training Requirements: The Principal Investigator or supervisor must provide initial training to all personnel using benzene. If airborne levels reach or exceed the AL, annual benzene training is required. The training content must include the hazards of benzene, safety information, regulatory requirements, signs and symptoms of possible exposures to benzene, and medical surveillance requirements. Medical Surveillance Any employee who is exposed to benzene above the AL for more than 30 days per year, or exposed to benzene above the PEL for more than 10 days per year, must be evaluated by the Occupational Health Nurse. Based on the evaluation results, the nurse may recommend further evaluation, exposure restrictions, or job reassignment. Contact EH&S at 206-543-7388 for safety information, guidance for air monitoring strategies, equipment and analytical result interpretation. Last revised on 09/06 UW Environmental Health and Safety Page D-7 February 2007 Appendix D – Example Standard Operating Procedures Laboratory Safety Manual Figure D-5 Example SOP for Ethidium Bromide Use University of Washington Standard Operating Procedures for Chemicals or Processes #1 Process (if applicable) Ethidium bromide, used in staining DNA. #2 Chemicals Ethidium bromide (CAS Registry Number 1239-45-8). The material fluoresces a red-orange color under ultraviolet light, with increased fluorescence when the material is bound to double-stranded DNA. Ethidium bromide is typically purchased in powder or solution form and is soluble in water. The crystal or powder form is odorless and appears dark red in color. The powder form is considered an irritant to the upper respiratory track, eyes and skin. Ethidium bromide is strongly mutagenic, causing living cell mutations. Even though there is no evidence at this time of human carcinogenicity or teratogenicity, this material should be considered a possible carcinogen or teratogen. SybrSafe is a safer alternative to ethidium bromide. While it should be handled and disposed of as ethidium bromide, it is somewhat less mutagenic and therefore safer to handle. #3 Personal Protective Equipment (PPE) Lab coat, chemical splash goggles and nitrile gloves are required. Leave lab coats in the lab when your work is complete to prevent the spread of this or other chemicals outside of the lab. When an ultraviolet light source is used in your work with ethidium bromide, added caution is required. As a general rule, avoid exposing unprotected skin and eyes to intense UV sources. If the UV light is aimed upwards, wear a UV protective face shield when you are standing near the source. For prolonged work close to UV light boxes or other intense sources, it may be useful to wrap the end of the lab coat sleeves loosely with masking tape to prevent gaps where the wrist could be exposed. For lowintensity UV sources, the requirement for UV protection can be waived if the exposure to personnel has been measured and shown to be within permissible exposure levels. Contact Radiation Safety at 206-543-0463 if you need measurements of the UV levels in your facility. #4 Environmental / Ventilation Controls All operations involving powder or mists of ethidium bromide must be done in a fume hood. Check for proper operation of the fume hood prior to use. #5 Special Handling Procedures & Storage Requirements Liquid: Store in the dark and the cold, preferably in a plastic container. #6 Spill and Accident Procedures When working with ethidium bromide, try to minimize the potential for spills. Where practical, purchase ready-made stock solutions from chemical manufacturers in lieu of mixing your own solutions. If you prefer to mix your own solutions of ethidium bromide, protect yourself by doing this process in a fume hood. Perform all processes that generate ethidium bromide dusts or mists inside the fume hood to minimize inhalation exposures. Prevent accidents by transporting small quantities of ethidium bromide in a secondary container instead of carrying large quantities. Solid: Store at the designated area. Spills of ethidium bromide solutions should be absorbed and decontaminated with soap and water. Avoid raising dust when cleaning up solid spills by mixing with water and then absorbing the solution. All spill cleanup materials and absorbents should be UW Environmental Health and Safety Page D-8 February 2007 Appendix D – Example Standard Operating Procedures Laboratory Safety Manual bagged or placed in a sealed container with a hazardous waste label. Some facilities use a hand held UV lamp to check for residual ethidium bromide contamination following spill cleanup. A reddish-orange fluorescence can be detected under both "long" and "short" UV wavelengths. Users of the hand held lamps should be aware that their ability to detect small spills is not guaranteed. The ease of detection depends upon a variety of factors including the chemical composition of the sample, the wavelength of the UV lamp, and the intensity of the lamp. Use of a hand held UV lamp to detect traces of ethidium bromide may serve as an occasional check of laboratory practices, but it cannot substitute for good cleanliness and careful contamination control. #7 Waste Disposal EH&S recommends that ethidium bromide waste be treated using special filters. These filters use ion-exchange resins and activated charcoal to remove the ethidium bromide from solution. There are effective chemical treatments to destroy ethidium bromide, but filtering is an easier and safer choice. See http://www.ehs.washington.edu/epohazreduce/index.shtm for more information. Powders, concentrated solutions, and grossly contaminated items are hazardous waste.

Permissible exposure limit (PEL) (8hrs.): 0.75 ppm, short term exposure limit (STEL) (15 min.) 2 ppm, action level (8hrs.): 0.5 ppm. Any product capable of releasing formaldehyde vapor of 0.1 to 0.5 ppm must be labeled that it contains formaldehyde, the availability of physical and health hazard information, and the name and address of the responsible party. For products capable of releasing formaldehyde vapor at levels of 0.5 ppm or above, the label must include the physical and health hazards as well as the warnings "respiratory sensitizer" and "potential cancer hazard". Chemical splash goggles and nitrile gloves must be worn to prevent eye contact and limit dermal exposure. A lab coat or apron is also required. #3 Personal Protective Equipment (PPE) #4 Environmental / Ventilation Controls Formaldehyde-containing solutions and preserved samples should be dispensed and used only in a properly operating fume hood. Routine use outside of a fume hood is acceptable only when formaldehyde levels are monitored and are below 0.5 ppm. Employers must determine by breathing zone air monitoring if employees are over exposed to formaldehyde. If the result of 8 hour monitoring is below the action level and the 15 minute monitoring is below the STEL, then no further air monitoring is required. However, if the work procedure changes, then monitoring must be repeated to ensure acceptable exposure levels. Affected employees must be informed of the formaldehyde exposure levels within 15 days of receiving the monitoring results. An employee reporting significant eye, nose, throat or dermal irritation or sensitization which might be a result of occupational exposure to formaldehyde shall be evaluated by the University's Occupational Health Professional. Based on the medical evaluation results, the Occupational Health Professional may recommend further evaluation, workplace exposure restrictions or reassignment. #5 Special Handling Procedures & Storage Requirements Mixing or dispensing should be done in a hood.
