At The University of Iowa, individuals are responsible for their own spills. Each hazardous material user must be ready and equipped to handle a spill. Critical elements for a safe and effective response are: information and knowledge of materials used, adequate spill response supplies, adequate training, and knowing when and who to call for assistance.
The Lab Standard and Right-to-Know Programs require emergency and spill response training. When preparing your response plan consider the location, existing ventilation, and nature of potential spills. EHS is available for guidance and training to facilitate your response planning.
- Ensure you have access to Safety Data Sheets (SDSs) for the hazardous materials you use.
- SDSs are maintained in VelocityEHS, which can be accessed through any computer at MSDSOnline or by calling 888-362-7416. UI staff are required to keep their chemical inventory up-to-date in EHS Assistant such that EHS staff can update VelocityEHS with SDSs for newly purchased chemicals. Active EHS Assistant users can access the inventories and SDSs from outside the lab in the event of an emergency.
- Understand the properties and hazards of the materials before beginning to use them.
- Maintain a call list (daytime and after-hours) of individuals who should be notified in an emergency.
- Collect and maintain spill response supplies. Sources include: lab safety suppliers, Biochemistry and Chemistry Stores.
- Know the location of and how to use emergency equipment such as emergency showers and eye washes.
- Train and practice for effective spill response.

How to Respond to Spills
Step 1: Attend to Personal Injuries
Step 2: Assess the Risk
Step 3: Initiate Action
Clothing on fire: Roll person on floor to smother flame, drench with water if immediately available.
Splash in eyes: Immediately rinse eyes with water continuously for 15 minutes. Forcibly hold eye open to rinse behind eyelids. Obtain medical attention.
Spill on body: Remove contaminated clothing and flood exposed area with running water from faucet or safety shower for 5 minutes. Make sure spill has not accumulated in shoes.
For biological spills: wash exposed area with soap and water.
Minor cuts and puncture wounds: Wash vigorously with soap and water, bandage wound, seek medical help if necessary.
Major spills meet any one of these criteria:
Simple spills meet all these criteria:
Report all personal injuries to your supervisor. Medical attention is available 24 hours at UIHC Emergency Treatment Center, telephone 356-2233.
Types of Spills
Radioactive Spill General Guide
- Restricting movement of all personnel is essential; movement of people around a radiation spill can spread radiation beyond the immediate spill area.
- Consider persons in area contaminated until monitoring proves otherwise.
- Dispose of cleanup materials as radioactive waste.
- Safely store non-disposable contaminated items for decontamination or decay.
- Report all spills to your PI/supervisor and EHS.
A simple radioactive materials spill is one that is manageable and can be cleaned up as a non- emergency.
Simple Spill description includes:
- can be safely managed by knowledgeable personnel
- personnel contamination can be prevented and controlled
- minimal potential to endanger personnel or the environment
- spread can be contained and controlled
- area or equipment can be isolated and cleaned up under non-emergency conditions
- personnel exposure to volatile material can be prevented
Simple Radioactive Materials Spill Actions
- Alert people in the spill area.
- Monitor them for contamination using a survey meter and decontaminate as necessary.
- Wear protective apparel; place absorbent pad over liquid spills, damp absorbent pad over solid spills.
- Place spilled material in a radioactive materials waste container; then clean with normal lab cleaning agents, working from outer spill edges inward.
- Monitor area and personnel.
- Repeat cleanup until no contamination is detected, disposing of all clean-up materials as radioactive waste.
- Notify EHS at 335-8501 and your PI or supervisor.
A major radioactive materials spill or emergency meets any one of the following criteria:
- spreads rapidly
- endangers people or involves serious personal injury
- endangers the environment
- has created significant personnel or equipment contamination
Major Radioactive Materials Spill Actions
- Evacuate the area; close doors and prevent entrance into area.
- Have potentially contaminated people stay in one area until they have been monitored.
- Call 911 immediately; notify EHS at 335-8501 as soon as possible.
Chemical Spill General Guide
- Isolate the spill area and alert others in the area.
- Determine identity of spilled material and consult SDS to determine potential hazard(s).
- Avoid breathing vapors, get as much fresh air into area as you can safely.
- Establish ventilation to the outside if safe to do so and action does not spread the contaminant through the building.
- Use absorbents and neutralizing agents that are compatible with chemical spilled.
- Prevent spilled chemicals from going down drains to avoid affecting the environment.
- Dispose of cleanup materials as chemical hazardous waste; small volumes (<100ml) of dilute acids and bases may be neutralized (pH 6-8) and sewered.
- Call EHS for hazardous waste pickup or for guidance on cleanup or air monitoring.
- alert people in area
- wear protective equipment
- contain by diking with appropriate absorbent
- if flammable, remove ignition sources (burners, motors, anything that could cause a spark); use plastic or nonmetallic cleanup equipment
- absorb or neutralize with appropriate agent working from outside edges inward; sorbents do not remove toxic or flammable hazards; neutralization can produce heat causing boiling and splattering
- acid—use sodium bicarbonate or acid spill kit
- base—use sodium bisulfate, citric acid, or base spill kit
- formaldehyde--absorb or use polymerizer
- if not water reactive, dampen to prevent airborne dust
- control water reactive dust with sweeping compound
- carefully brush solids into a dust pan or container
- keep dust generation down to prevent creating inhalation hazard
Compressed gas leak—simple (presents no or only minimal inhalation or fire hazard)
- remove ignition sources
- restrict access
- place in or next to fume hood if possible; tighten fittings
- locate leak with soapy water (at below freezing temperatures use 50% glycerin solution)
- if cylinder still leaks, contact supplier
- notify your PI/supervisor
Compressed gas leak--major
Large or uncontrollable leak or fire hazard, involves acutely toxic gas, and/or more than minimal personal risk
- alert others to evacuate
- call 911
- turn off ignition sources
- leave fume hoods running; ventilate the affected area prior to leaving the area (only if it can be done safely and only to the outside)
- evacuate; assemble in a remote location; account for people
- provide information to emergency responders
Large or heated spills can be an inhalation hazard
- isolate area to prevent tracking
- wear gloves and shoe covers (if on floor)
- consolidate and collect droplets using scraper, cardboard, wet paper towel, aspirator bulb, tape or special sponge (can be purchased from Biochemistry Stores)
- place all waste in sealed container; contact EHS for hazardous waste pickup
Evacuate, call 911, and wait for responders.
