7. Clean-up procedures in case of a spill
- the type of chemical(s) spilled,
- the amount (< 1 L),
- the hazardous characteristics of the spilled chemical,
- the location, • the proper method for cleaning up the spill,
- the personal protective equipment available, and
- the training of the laboratory's personnel.
Simple spills do not include unknown, highly reactive, large-volume, or high-toxicity releases. For these situations, evacuate the area, close the door if safe to do so, call 911 or UT Tyler Dispatch, and contact EH&S.
For simple spills, emergency responders do not need to be notified. However, you should contact the environmental health and safety office or other responsible person within your facility. Most importantly, before cleaning up a simple spill, be sure that you can do so safely. You must have the right personal protective equipment, including, at a minimum, appropriate eye protection, protective gloves, and a lab coat. Additional protective equipment may be required for spills that present special hazards (such as corrosive or reactive spills or spills that have a splash potential). The following steps should be taken during spill cleanup:
- Prevent the spread of dusts and vapors.
- If the substance is volatile or can produce airborne dusts, close the laboratory door and increase ventilation (through fume hoods, for example) to prevent the spread of dusts and vapors to other areas.
- Neutralize acids and bases, if possible.
- Spills of most liquid acids or bases, once neutralized, can be mopped up and rinsed down the drain (to the sanitary sewer). However, be careful because the neutralization process is often vigorous, causing splashes and yielding large amounts of heat. Neutralize acids with soda ash or sodium bicarbonate. Bases can be neutralized with citric acid or ascorbic acid. Use pH paper to determine when acid or base spills have been neutralized. Do not dispose of spill residues down the drain unless the SDS and EH&S guidance specifically allow it.
- Control the spread of the liquid.
- Contain the spill with the spill kit materials located under the lab sink. Make a dike around the outside edges of the spill. Use absorbent materials such as vermiculite, cat litter, or spill pillows.
- Absorb the liquid.
- Add absorbents to the spill, working from the spill's outer edges toward the center. Absorbent materials, such as cat litter or vermiculite, are relatively inexpensive and work well, although they are messy. Spill pillows are not as messy as other absorbents, but they are more expensive. Note that special absorbents are required for chemicals such as hydrofluoric and concentrated sulfuric acids.
- Collect and contain the cleanup residues.
- The neutralized spill residue or the absorbent should be scooped, swept, or otherwise placed into a plastic bucket or other container. For dry powders or liquids absorbed to dryness, double bag the residue using plastic bags. Additional packaging may be required before the wastes can be transported from your laboratory. For spills of powders or solid materials, you may need to add a dust suppressant. Be sure to place descriptive labels on each container.
- Dispose of the wastes.
- Keep cleanup materials separate from normal trash. Contact your environmental health and safety officer for guidance in packaging and labeling cleanup residues. Promptly place cleanup wastes in an appropriate hazardous waste receptacle.
- Decontaminate the area and affected equipment.
- Ventilating the spill area may be necessary. Open windows or use a fan unless the area is under negative pressure. In some instances, your environmental health and safety officer can test the air to ensure that hazardous vapors are gone. For most spills, conventional cleaning products, applied with a mop or sponge, will provide adequate decontamination. If you have any questions about the suitability of a decontaminating agent, seek expert advice.
8. Guidance on what to do in case of emergency
- If there is immediate danger to you, leave the laboratory immediately and call 911.
- In this laboratory, a small, incipient fire may require the use of the lab fire extinguisher (see map for location), if you are trained and it is safe to do so.
- If the building fire alarm sounds, follow emergency shutdown procedures for all running equipment and leave the building through the nearest exit.
- Know the first aid treatment for the potential hazards of your equipment that may cause bodily injury or chemical exposure. For example, some liquids when exposed to the skin should be washed with water and some should not. KNOW THE HAZARDS YOU ARE DEALING WITH BEFORE AN EMERGENCY.
- For minor physical injuries, the first aid kit is located in the sink area cabinet (see map).
- If exposed to liquid chemicals, follow the directions on the SDS. If you experience any acute symptoms, call 911.
- If exposed to vapors, leave the area and go outside for fresh air. If you experience any acute symptoms, call 911.
- If you are uncertain what to do after exposure to a particular substance, call the EH&S emergency number: 903-566-7011 or Poison Control at 1-800-222-1222.
- During severe weather, stop work if safe to do so, secure hazardous materials, and move to RBN 1034 or the basement restrooms/designated shelter area.
