What would you do if the following occurred? List the actions/ responses you would take. Examples: Minor solvent spill: While running a column in DCM/MeOH under pressure, column glassware breaks causing solvent to splash all over the contents of your hood. A few flasks and column fractions are spilled. Major solvent spill: After returning from the stock room, 2 4L bottles of DCM are dropped (causing them to shatter) while moving them to the flammable cabinet. Fire: While working with Pd/C it spontaneously starts a fire on a lab bench. Injury: An out of place power cord causes someone to trip. The individual bumps his/her head on the edge of a lab bench and is bleeding. Stitches may be required. Emergency Response Procedures
Minor Solvent Spill Use spill kit for solvent outside hood. – (Do NOT use spill kits for HF, radioactive material, or mercury spills) If inside hood, close doors and sash. Notify lab mates. – Be conscious of solvent vapors (flammable, cause dizziness, etc.) Make sure there are no chemicals on you – remove lab coat, flush eyes, check shoes and other clothing Notify Chuck Tomlinson (4-2321) or Raul Caretta (5-8066) as soon as possible Spill kit locations? – In CHEM, large spill kits are located in near 681in Kolthoff and the hallway by the east elevator on the sub-basement in Smith. JST Emergency Response Information spills that do not pose an immediate hazard, clean up manageable by researcher
Major Solvent Spill Evacuate the area and alert others in the area Remove victims to fresh air – Remove contaminated clothing and flush contaminated skin and eyes with water for 15 minutes. – If anyone has been injured or exposed to toxic chemicals/vapors call 911 and seek medical attention immediately. Confine: close doors and isolate the area Contact emergency personnel – Call 911 and say "Call AHERPS. Be prepared to give basic information and be given some instructions. Contact the Front Office as soon as possible: – Chem (4-6000) CEMS (5-1313) JST Emergency Response Information Spill that presents an immediate hazard (fire, explosion, chemical exposure, etc.) or is a highly dangerous chemical.
Fire or Release of Toxic / Explosive Material If you are trained and the fire size is manageable, use fire extinguisher to put out fire. If unmanageable fire, remove all personnel from area. Close off area to prevent spread of hazardous material or fire. Call 911 to report the nature and location of the hazard. Activate the building alarm system at the nearest manual alarm station. In all cases, report the incident to the front office – Chem (4-6000) CEMS (5-1313) JST Emergency Response Information
Injury If minor, go to the U of M Hospital Emergency Room accompanied by another person. If the injury is serious dial 911 and describe your injury as well as your location. Notify Chuck Tomlinson (4-2321) or Raul Caretta (5-8066) A First Report of Injury must be filled out promptly JST Emergency Response Information
Assisting an Emergency Response In the event of a building evacuation, fire, police and other emergency responders will go to the north entrance of Smith Hall, facing Walter Library. – If you have information relevant to an incident, plan to head to the north entrance to meet them and answer questions.

Cleaning up a Chemical Spill How to use a spill kit
Evaluating a chemical spill Is help needed? Can this be handled with lab personnel? 19 Adapted from: Univ. of Wiscon. Environment, Health and Safety. Spill Response and Reporting Simple spill Can be cleaned up promptly by researcher Chemical Hazards Do I know what it is? Quantity Can I handle a spill of this size? Impacts Can this spill be contained? Training and Equipment Can I safely clean up the spill with the available PPE and equipment? Yes No Yes No Complex spill GET HELP! Call 911, if no imminent hazard (fire or major injury) ask for AHERPS for further assistance. Evacuate if needed. Container label is legible SDS is available Hazards: reactive, flammable, volatile Risks: health, physical property, or environment Training and experience Available PPE Available spill control materials Hazardous vapors/ dust Liquids can encounter ignition sources or incompatible materials Nearby classrooms or offices Available spill control materials to confine and absorb Physical layout of the spill
Cleaning up a chemical spill 20 Images: Minor spill clean up. Iowa State University, Environmental Health and Safety 1.Contact DEHS for guidance 2.Look up the SDS of the chemical Clean up procedures PPE requirements – put it on! Remember, Do NOT use spill kits for HF, radioactive material, or mercury spills (call DEHS). 3.Secure the area – Post do not enter signs 4.Control the spread of spill with absorbent materials (spill mats). 5.Neutralize acids and bases. Add neutralizer slowly from edges to center; Mix Test with pH (want pH from 6-8) For acids use sodium bicarbonate (baking soda) For bases use citric or ascorbic acid Before cleaning up a spill make sure that you can do so safely.

Chemical Spill Four-step Emergency Procedure
1.Evacuate and Aid Leave spill area and assist others in leaving Remove victims to fresh air; remove contaminated clothing/flush any exposed areas with excess water 2.Confine Without endangering yourself, close doors, isolate the spill area, and prevent entrance 3.Report Call EHS during working hours or 911 after hours State your name, phone, and location; describe the emergency, contents of the spill, injuries, etc. EHS will advise you what to do 4.Secure and Clean Block off entrances, lock doors, put up warning tape/signs on all entrances Follow instructions from EHS on how to clean the spill 26 Four-step Procedure
Chemical Spill Response Example from a Learning Experience Report (LER)
Chemical Spill Response After working hours, a 100mL bottle of trifluoroacetic acid was dropped. It broke, splashing on the floor and cabinets. The overwhelming odor caused a coworker to 911 and say, "Call AHERPS. The dispatcher contacted the AHERPS employee who determined the spill was not very dangerous could be resolved with the researchers, not 911's resources. The researchers wore masks, quarantined the spill with the spill barriers, neutralized the trifluoroacetic acid with baking soda and water as described in the SDS, and opened all fume hoods. 28
Chemical Spill Response The AHERPS employee followed up with the incident approximately min later to assess the current situation. No significant chronic effects, as the spill was neutralized and cleaned up quickly. No need for county emergency response personal (fire, police, etc.). DEHS person would pick up the spill clean up supplies the next day. 29 To prevent dropping a chemical bottle: 1.Dont hurry – take your time. 2.Securely hold bottles, using two hands for large or heavy containers.
Spill Kits Where are they: Kolthoff - northwest hallway near 681 Smith - hallway by the east elevator, sub-basement level In individual labs A reminder: Do NOT use spill pillows for HF, radioactive material, or mercury spills. See the safety moment on making spills kits and using the contents to clean up chemical spills. 30

Fire Extinguishers Types and compatibility
Four classes of fires
Proper Use of Fire Extinguishers For fires involving: wood cloth paper plastics
Proper Use of Fire Extinguishers For fires involving: gasoline kerosene oils flammable chemicals
Proper Use of Fire Extinguishers For fires involving: appliances motors computers
Proper Use of Fire Extinguishers For fires involving: lithium sodium magnesium potassium COMBUSTIBLE METALS
45 Fire extinguishers everywhere The fire extinguishers are designed to put out or control small fires. It is important that we equip facilities with the proper fire extinguishers as part of fire protection plan.
Water is one of the most commonly used extinguishing agents for type A fires. Always you can recognize an APW by its large silver container. They are filled about two-thirds of the way with ordinary water, pressurized with air. APWs are designed for Class A (wood, paper, cloth, rubber, and certain plastics) fires only. Air-pressurized water extinguishers
Carbon Dioxide extinguishers This type of extinguisher is filled with Carbon Dioxide (CO 2 ), a non-flammable gas under extreme pressure. These extinguishers put out fires by displacing oxygen, You can recognize this type of extinguisher by its hard horn and absent pressure gauge. CO 2 extinguishers are designed for Class B and C (flammable liquid and electrical) fires only.
Dry Chemical extinguishers Dry chemical extinguishers put out fires by coating the fuel with a thin layer of fire retardant powder, separating the fuel from the oxygen. The powder also works to interrupt the chemical reaction, which makes these extinguishers extremely effective. Dry Chemical extinguishers will have a label indicating they may be used on class A, B, and/or C fires. OR
Thermal Burns First aid treatment
Thermal burns 50 ABC of burns: Pathophysiology and types of burns BMJ June 12; 328(7453): 1427–1429. Burns: MedlinePlus Medical Encyclopedia
First aid for burns For minor burns, soak in cold water (not ice water) until the pain stops (5 min+) If the burn covers a large area of the body, apply cool wet dressings to that area Do not break any blisters Once the pain is subdued, apply antibiotic ointment or first aid gel to the area and bandage If necessary, seek medical attention for minor burns. 51 Burns: MedlinePlus Medical Encyclopedia DEHS
First aid for burns Minor burns will usually heal without further treatment. However, if a second-degree burn covers an area more than 2 to 3 inches in diameter, or if it is located on the hands, feet, face, groin, buttocks, or a major joint, treat the burn as a major burn For severe burns call 911 immediately and do not attempt to remove charred clothing 52 Burns: MedlinePlus Medical Encyclopedia DEHS
