3510 Appendix T5

Response to Chemical Spills[1]



Jefferson Lab has determined that working with chemicals carries an unmitigated Risk Code >2. At a minimum all tasks requiring chemicals are discussed with the supervisor prior to commencement of work. An Operational Safety Procedure (OSP) is written for work considered to be Risk Code >2 in accordance with ES&H Manual Chapter 3210 Work Planning, Control, and Authorization Process.


1.0            Purpose


Jefferson Lab considers spills to be a hazard. This procedure provides minimum action steps and contact information to ensure prompt response and safe clean-up of a chemical spill. 


The process steps satisfy applicable federal, state, and local requirements as outlined in ES&H Manual Chapter 2410 Appendix T1 Hazard Issues List.


2.0            Scope


Only those who are trained are authorized to clean-up a spill involving hazardous material. It is recognized that listing the requirements for every chemical used at Jefferson Lab would be prohibitive, it is therefore required that qualified chemical workers read and follow the requirements/recommendation for spill clean-up listed on a chemical’s safety data sheet (SDS).  


This appendix is written in coordination with ES&H Manual 3510 Emergency Response Activities and ES&H Manual 6610 Chemical Hygiene Program.


3.0            Responsibilities

NOTE:           Management authority may be delegated to a task qualified Jefferson Lab employee at the discretion of the responsible manager.


3.1              Anyone at Jefferson Lab

·         If you see or produce a chemical spill, contact:

o   Security at 269-5822, or

o   Request assistance from the Hazardous Waste Coordinator at 269-7308.


3.2              Hazardous Waste Coordinator

·         Provide chemical waste disposal assistance.


4.0            Process Steps


If there is personal over-exposure to a chemical immediately call 911 and follow the process steps outlined in ES&H Manual Chapter 6610 Appendix T6 Response to Chemical Over-Exposure.


Unless otherwise stated anyone at Jefferson Lab may perform the following process steps.


4.1              Spills


Step 1:             Protect yourself and others.


Step 2:             Note the material, location, and quantity.




IF spill is



Evacuate (~100ft) upwind.


Evacuate the room and close all doors and windows.


Step 3:             Call Security (269-5822) and the Hazardous Waste Coordinator at 269-7308 immediately and give the following information:

o   Identity of the material

o   Location of the spill

o   Approximate quantity

o   Other hazards or emergency conditions (traffic or personnel concerns) as requested


Step 4:             Contain the Release (if safe to do so):

o   Block drains to prevent seepage into the sewer or storm system (this includes indoor plumbing and outdoor storm systems).  

o   Construct a barrier around the spill using spill pads, socks, from an appropriate spill kit, or other compatible material as available (e.g.: soil) to prevent spreading and to minimize damage.


Step 5:             Wait and/or direct responders to the spill. 


4.2              Waste Clean-up and Disposal


Remove waste and other suspect material left after completion of clean-up procedure(s).
