Standard Operating Procedure Benzene This is an SOP template and is not complete until: 1) lab specific information is entered into the box below 2) lab specific protocol/procedure is added to the protocol/procedure section and 3) SOP has been signed and dated by the PI and relevant lab personnel. Print a copy and insert into your Lab-Specific Chemical Hygiene Plan. Section 1 Lab-Specific Information – Building/Room(s) covered by this SOP: Department: Principal Investigator Name: Principal Investigator Signature: Section 2 Hazards – Benzene is an OSHA regulated carcinogen. It is a highly flammable liquid and may form explosive mixtures with air. It can be harmful if inhaled, causing respiratory irritation. Benzene is harmful if absorbed through skin and causes eye and skin irritation. It may cause cancer and genetic defects. Exposure Limits: OSHA PEL (8 HR. TWA): 0.5 ppm OSHA Short Term Exposure Limit: 1 ppm ACGIH TLV/TWA: 0.1 ppm Section 3 Engineering Controls and Personal Protective Equipment (PPE) – Engineering Controls: Benzene should be used in a properly functioning chemical fume hood whenever possible. The chemical fume hood must be approved and certified by REM and have a face velocity between 80 125 feet – per minute. contact with skin, eyes, and clothing. Wash hands before breaks and immediately after Hygiene Measures: handling the product. Hand Protection: Chemical-resistant gloves must be worn, nitrile gloves are recommended for low volume applications. Wearing two pairs of nitrile gloves is recommended. If handling a high volume (> 1 liters) of Benzene, then disposable gloves are likely not suitable; a more heavy duty glove such as a butyl rubber is required. NOTE: Consult with your preferred glove manufacturer to ensure that the gloves you plan on using are compatible with the specific chemical being used.
