Short answer
Move people away and upwind. Call 911 if there is fire, an injury, strong vapor, or a substance you cannot name. Shut off anything that could spark, but only if it is safe. Protect nearby drains if you can do it without exposure. Find the safety data sheet and write down times and actions. Then call your spill response company and any agencies you must notify.
The first minute
Get people away from the spill. Move them upwind and uphill if you can, since vapors travel with the air and liquids run downhill. Do not let anyone walk through the spill or stay to look at it.
Call 911 if there is a fire, an injury, a strong vapor, a large release, or a substance you cannot name. Tell the dispatcher what you know and what you do not know. Say if anyone was exposed. Emergency responders will take charge of the scene.
If someone was splashed or a vehicle is leaking
If a person was splashed, help them away from the spill. Follow the first aid steps on the safety data sheet, the maker's fact sheet for the product, if you have it. Flushing skin and eyes with water is a common first step for many chemicals. But check the sheet if you can do so fast.
The spill may have come from a vehicle, such as a tanker, a delivery truck, or a company van. If so, look for hazard signs or shipping papers from a safe distance and tell the dispatcher what you see. Do not go up to a leaking vehicle to read labels.
Do not try to be a hero. Your job in the first minute is to keep people safe and get trained help on the way.
Act now or wait for responders?
Your written spill plan should draw this line ahead of time. In general, trained staff may handle small spills of known, low-risk materials with the right spill kit and protective gear. Everything else waits for trained responders.
Wait for responders if you do not know what the material is. Wait if there is a strong odor or vapor you can see, or if the spill is large or spreading fast. Wait if there is any risk of fire or a spark, or if you do not have the right protective gear. Also wait if anyone has symptoms.
When in doubt, close off the area and call. No spill company or fire department will ever fault you for asking for help with a spill you were unsure about.
Trained staff and after-hours shifts
If your site has trained spill responders on staff, tell them at once and let them size up the spill. Their training and your spill plan decide what they can safely do.
Spills after hours need special planning. Night and weekend crews are often smaller and may include newer staff. Make sure every shift knows the order of calls and where the spill kits and safety data sheets are kept.
What can I safely do to limit the spill?
If you are trained and it is safe, a few quick actions can make a spill far smaller. Do each one from a safe spot, without stepping into the spill or the vapors.
- Stop the leak if it is simple and safe, such as closing a valve or setting a container upright
- Shut off anything that could spark near material that burns, if you can do it without entering vapors
- Place drain covers or absorbent socks to keep liquid out of storm drains and floor drains
- Ring the spill with absorbent barriers or socks to stop it from spreading
- Close doors to hold vapors inside a room, and shut off fans or air systems that might spread them
- Keep vehicles and forklifts away from the spill area
Using the safety data sheet quickly
The safety data sheet is your best source of quick facts about a known product. Keep your sheets in order and easy to reach. The best setup is paper copies near storage areas plus a digital library.
In an emergency, go to the sections on hazards, first aid, firefighting, accidental release, and exposure controls. They tell you if the material can burn or is toxic. They tell you what protective gear is advised and how to contain and soak it up.
Hand the sheet to responders when they arrive. Emergency crews and spill companies rely on it to choose their gear and methods. Having it ready saves time.
If the material is unknown, tell responders what you do know. That may be container labels, hazard signs on a vehicle, the process that was running, or the smell and color of the liquid.
If your library is missing a product, make a note to ask the supplier for the sheet after the incident. Gaps are common and easy to fix once someone notices them.
What should I avoid doing?
Some actions make a spill bigger or more dangerous. Many of them feel helpful in the moment. That is why it is worth knowing them ahead of time.
Do not wash spilled material toward a drain with water. Do not use an absorbent that is unsafe with the chemical. Some absorbents, for example, react with strong oxidizers, chemicals that feed fire. Do not mix chemicals or try to neutralize something unless you are trained and the safety data sheet supports it.
Do not use electrical equipment, vehicles, or anything that could spark near liquids or vapors that burn. Do not take off dirty clothing or gear carelessly. Bag it for proper disposal.
Do not send staff back into a building for belongings, paperwork, or equipment while vapors may still be present. Those items can wait until responders say the area is safe.
Last, do not assume the spill is someone else's problem. If you find it, you are the one who can start the right chain of calls.
Whom do I need to call, and when?
Write the order of calls into your spill plan and post it near your spill kits. A typical order looks like the list below, but your site may differ.
Your duty to report depends on the material, the amount, and where it went. Some reports must be made within hours. Your environmental manager or spill company can help you work out which agencies apply. The spill line at your state environmental agency can confirm if a report is needed.
- 911, if there is fire, injury, strong vapor, a large release, or an unknown substance
- Your in-house emergency coordinator or environmental manager
- Your spill response company
- Required agencies, which may include local, state, and federal contacts depending on the release
- Your insurer, once the emergency is under control
- Neighbors or tenants, if the spill could affect them
What a well-handled urgent spill looks like
A well-handled urgent spill rarely looks dramatic. It may be battery acid pooling in a warehouse aisle or fuel on a loading dock. Either way, the same few moves happen in about the same order, and each one is small.
Someone clears the aisle and sends people to a set meeting point away from the spill. A trained responder puts on the gloves, goggles, and apron from the spill station. That person covers the nearest floor drain and rings the spill with an absorbent that is safe with the material. That person does not try to handle cracked or damaged containers.
Meanwhile, someone else pulls the safety data sheet. That person calls the site's environmental coordinator and the contracted spill company. The company neutralizes or soaks up the material, packs the damaged containers and waste, and provides closeout records. The coordinator confirms if anything reached a drain and writes up the incident.
Afterward, the site restocks the spill station and looks at what caused the release, such as a rack that needs inspection. At the next safety meeting, it walks the shift through what happened. In most cases, a quick drain cover and the correct absorbent are what keep a spill in one area. Without them, it could have become a release that must be reported.
Communicating with people nearby
Clear messages keep people safe and cut down on panic. Tell employees, tenants, or neighbors what they need to do, not everything you know. Simple instructions are easier to follow. Examples are to avoid the east lot or to stay indoors with windows closed.
People tend to follow clear guidance. In a 2015 study of the 2014 chemical spill in West Virginia, Savoia and colleagues reported that 70% in affected counties reported following recommended behaviours. Give people something clear to follow, and update them as things change.
Choose one person to handle messages so they stay the same from start to finish. Keep a log of what was said, to whom, and when.
What should I record while it is happening?
Records made during the incident are more reliable than memories pieced together later. Assign someone to keep a simple log, and let responders take the lead on the scene.
Record the time you found the spill and what spilled, if known. Record the estimated amount, where it went, and who was exposed. Record what actions were taken and when, and whom you called. Take photos only when it is safe to do so.
These records support your reports to agencies, your insurance claims, and your own review afterward. They also help you improve your spill plan, spill kits, and training for the next time.
Keep the log in one file with the spill company's closeout package, the waste shipping records, and any letters from agencies. If questions come up months later, everything will be in one place.
