9: Spill Response/Emergency Procedures

In the event of a chemical spill, the individual(s) who caused the spill is responsible for prompt and proper clean-up. It is also their responsibility to have spill control equipment appropriate for the chemicals being handled readily available. There should be a sufficient quantity of absorbents or other types of materials to control any spill that can be reasonably anticipated. Vermiculite, lined 5-gallon pails and limited spill control materials are available at the loading docks of Lewis Thomas Lab, Frick, and E-Quad. Additional materials may be found in certain laboratories and the chemical stockrooms.

The following are general guidelines to be followed for a chemical spill. More detailed procedures may be available from your Departmental Safety Manager.

1. Immediately alert room occupants and supervisor, and evacuate the area, if necessary.

2. If there is a fire or medical attention is needed, contact Public Safety at 911.

3. Attend to any people who may be contaminated. Contaminated clothing must be removed immediately and the skin flushed with water for no less than fifteen minutes. Clothing must be laundered before reuse.

4. If a volatile, flammable material is spilled, immediately warn everyone, control sources of ignition and ventilate the area.

5. Don personal protective equipment, as appropriate to the hazards. Refer to the Material Safety Data Sheet or other references for information.

6. Using the chart below, determine the extent and type of spill. If the spill is large, if there has been a release to the environment or if there is no one knowledgeable about spill clean-up available, contact EHS at x8-5294 or Public Safety at 911.

7. Consider the need for respiratory protection. The use of a respirator or self-contained breathing apparatus requires specialized training and medical surveillance. Never enter a contaminated atmosphere without protection or use a respirator without training. If respiratory protection is needed and no trained personnel are available, call EHS at x8-5294 or Public Safety at 911. If respiratory protection is available, be sure there is another person outside the spill area in communication, in case of an emergency. If no one is available, contact Public Safety.

8. Protect floor drains or other means for environmental release. Spill socks and absorbents may be placed around drains, as needed.

9. Clean-up the spill according to the table above.

• Loose spill control materials should be distributed over the entire spill area, working from the outside, circling to the inside. This reduces the chance of splash or spreading of the spilled chemical.
• Bulk absorbents and many spill pillows do not work with hydrofluoric acid. POLYZORB products and their equivalent will handle hydrofluoric acid.
• Many neutralizers for acids or alkalines have a color change indicator to show when neutralization is complete.

10. When spilled materials have been absorbed, use brush and scoop to place materials in an appropriate container. Polyethylene bags may be used for small spills. Five gallon pails or 20 gallon drums with polyethylene liners may be appropriate for larger quantities.

11. Complete a hazardous waste sticker, identifying the material as Spill Debris involving XYZ Chemical, and affix onto the container. Remember that the use of an adsorbent does not alter the chemical properties of that chemical. Contact EHS at x8-5294 for advice on storage and packaging for disposal, and see section 10 for correct labeling procedures for hazardous waste.

12. Place the container in a hood or other properly ventilated area until the next hazardous waste pickup.

13. Decontaminate the surface where the spill occurred using a mild detergent and water, when appropriate.

14. Report all spills to your supervisor.

Recommended Equipment for Spill Kits

Personal Protective Equipment

2 pairs chemical splash goggles

2 pairs of gloves (recommend Silver Shield or 4H)

2 pairs of shoe covers

2 plastic or Tyvek aprons and/or Tyvek suits

Absorption Materials

4 POLYZORB spill pillows (or equivalent)

1 POLYZORB spill sock

2 DOT pails (5 gallon) with polyethylene liners

• 1 filled with loose absorbent, such as vermiculite or clay
• 1 with minimum amount of loose absorbent in the bottom

Neutralizing Materials

Acid Neutralizer

	Caustic Neutralizer, such as Neutracit-2 -Commercial neutralizers, such as Neutrasorb (for acids) and Neutracit-2 (foralkaline) have built in color change to indicate complete neutralization

Solvent Neutralizer - Commercial solvent neutralizers, such as Solusorb, act to reduce vapors and raise the flahpoint of the mixture

Mercury Spills

Small mercury vacuum to pick up large drops (optional)

Hg Absorb Sponges - amalgamate mercury residue

Hg Absorb Powder - amalgamates mercury

Hg Vapor Absorbent - reduces concentration of vapor in hard to reach areas

Mercury Indicator - powder identifies presence of mercury

Clean-up Tools

Polypropylene scoop or dust pan

Broom or brush with polypropylene bristles

2 polypropylene bags

sealing tape

pH test papers

waste stickers

floor sign - DANGER Chemical Spill - Keep Away
