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.

Keep in Mind
Ventilation Fume hood < vented cabinet < lab < hall < closet
Risks• Explosives / air, water, temperature reactive
– Dangerous, but rare; likely already reacted prior to clean up of residue
• Fire / volatile / inhalation hazards– Tricky to evaluate; Call DEHS (911 + AHERPS)
• Contact hazards (corrosives / toxic via ingestion)– Most likely can be handled by lab (unless at high concentration or
volume)
• Delayed effect (carcinogens / environmental hazards)– Handled by lab
24
Lower risk Higher risk

![Page 28: Www.jst.umn.edu Safety Moment Collection of the Joint Safety Team at the University of Minnesota, Department of Chemistry and Department of Chemical Engineering](https://reader034.vdocument.in/reader034/viewer/2022050720/55189dee550346c31f8b474c/html5/thumbnails/28.jpg)
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
![Page 29: Www.jst.umn.edu Safety Moment Collection of the Joint Safety Team at the University of Minnesota, Department of Chemistry and Department of Chemical Engineering](https://reader034.vdocument.in/reader034/viewer/2022050720/55189dee550346c31f8b474c/html5/thumbnails/29.jpg)
Chemical Spill Response
The AHERPS employee followed up with the incident approximately 15-20 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. Don’t hurry – take your time. 2. Securely hold bottles, using two hands for large or heavy
containers.

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.

Carbon 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.

www.jst.umn.edu
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.

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.

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

When to use an AED
• Use an AED on persons experiencing Sudden Cardiac Arrest (SCA). Symptoms include:– Unable to respond when you try to wake them– No breathing or abnormal breathing– No detectable pulse– Blue color in skin– Person might move, spasm
• Before using an AED:– Confirm that the person cannot respond to shaking or shouting– Call 911 (or have someone else do it)– Chances of survival increase if someone starts CPR while another gets
the AED– Make sure person is in a dry area (no puddles, flowing water sources)

Example Summary of Report
Example: A mercury spill occurred when rearranging oven shelving, during pm working hours. No injury resulted. The participate somewhat knew what do in the incident (7/10), but did not have much prior experience with the activity/technique during which the incident occurred (5/ 10). To prevent incident: 1. Mercury thermometers should not be used in the first
place.2. More care should have been taken when rearranging
oven shelving.
For information on how to deal with a Hg spill, please see the related safety moment.
