8Emergency Response Procedures 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.Use lab-specific accidents that could occur.This is a unique way to review the emergency response procedures document.
9Minor Solvent Spill Use spill kit for solvent outside hood. spills that do not pose an immediate hazard, clean up manageable by researcherUse 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 youremove lab coat, flush eyes, check shoes and other clothingNotify Chuck Tomlinson (4-2321) or Raul Caretta (5-8066) as soon as possibleSpill 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
10Major Solvent Spill Evacuate the area and alert others in the area Spill that presents an immediate hazard (fire, explosion, chemical exposure, etc.) or is a highly dangerous chemical.Evacuate the area and alert others in the areaRemove victims to fresh airRemove 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 areaContact emergency personnelCall 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
11Fire 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 officeChem (4-6000) CEMS (5-1313)JST Emergency Response Information
12InjuryIf 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 promptlyJST Emergency Response Information
13Assisting 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.Walter LibraryFire Dept.

20Cleaning up a chemical spill Before cleaning up a spill make sure that you can do so safely.Contact DEHS for guidanceLook up the SDS of the chemicalClean up proceduresPPE requirements – put it on!Remember, Do NOT use spill kits for HF, radioactive material, or mercury spills (call DEHS).Secure the area – Post do not enter signsControl the spread of spill with absorbent materials (spill mats).Neutralize acids and bases.Add neutralizer slowly from edges to center; MixTest with pH (want pH from 6-8)For acids use sodium bicarbonate (baking soda)For bases use citric or ascorbic acidNOTE: Do not neutralize acids that contain heavy metals or are oxidizing acids. Examples: chromic acid, perchloric acid, fuming nitric acid, and hydrofluoric acidsImages: Minor spill clean up. Iowa State University, Environmental Health and Safety
21Cleaning up a chemical spill Absorb the liquid with spill mats or other absorbentBe careful not to be cut by any glass shardsCollect and contain the cleanup residuesPlace in a plastic waste container/bucker or double layered plastic bags.Label with a yellow hazardous waste label and a red solid waste sticker.Contact DEHS personnel for more information.Decontaminate the area and effected equipment.Vent the spill area (open doors/windows, use a fanClean area with soap and water with a mop or spongeHazardousWasteImages: Minor spill clean up.

26Four-step Procedure Evacuate and Aid Leave spill area and assist others in leavingRemove victims to fresh air; remove contaminated clothing/flush any exposed areas with excess waterConfineWithout endangering yourself, close doors, isolate the spill area, and prevent entranceReportCall EHS during working hours or 911 after hoursState your name, phone, and location; describe the emergency, contents of the spill, injuries, etc.EHS will advise you what to doSecure and CleanBlock off entrances, lock doors, put up warning tape/signs on all entrancesFollow instructions from EHS on how to clean the spill
27Chemical Spill Response Example from aLearning Experience Report (LER)
28Chemical 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.
29Chemical 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.To prevent dropping a chemical bottle:Don’t hurry – take your time.Securely hold bottles, using two hands for large or heavy containers.

32Call Emergency personal Can you handle it?If you doubt your ability to fight a fire…EVACUATE IMMEDIATELYandCall Emergency personalIf you are trained and the fire size is manageable,use fire extinguisher to put out fire.
33Following the P.A.S.S Technique Pull…Aim…Squeeze…Sweep…
34Following the P.A.S.S Technique Pull……Pull the pin. This will also break the tamper seal.
35Following the P.A.S.S Technique Aim……Aim low, pointing the extinguisher nozzle (or its horn or hoses) at the base of the fire.Note: Do not touch the plastic discharge horn on CO2 extinguishers, it gets very cold and may damage skin.
36Following the P.A.S.S Technique Squeeze……Squeeze the handle so that it will release the extinguishing agent.
37Following the P.A.S.S Technique Sweep……Sweep from side to side at the base of the fire until the extinguisher is completely empty assuring that the fire is out.

45Fire 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.
46Air-pressurized water extinguishers 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.
47Carbon Dioxide extinguishers This type of extinguisher is filled with Carbon Dioxide (CO2), 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.CO2 extinguishers are designed for Class B and C (flammable liquid and electrical) fires only.
48Dry 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

51First aid for burnsFor 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 areaDo not break any blistersOnce the pain is subdued, apply antibiotic ointment or first aid gel to the area and bandageIf necessary, seek medical attention for minor burns.Burns: MedlinePlus Medical EncyclopediaDEHS
52First aid for burnsMinor 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 burnFor severe burns call 911 immediately and do not attempt to remove charred clothingBurns: MedlinePlus Medical EncyclopediaDEHS
