ES&H Manual



3510 Appendix T6

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 chemical spills to be an environmental hazard. This procedure provides minimum action steps and contact information to ensure prompt, 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


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 material safety data sheet (MSDS). This procedure defines actions required by Jefferson Lab in addition to those listed on the MSDS.



This appendix is written in coordination with ES&H Manual 6610 Chemical Hygiene Program and ES&H Manual 3510 Emergency Response Activities. All applicable content within the chapters applies to the procedure outlined in this appendix.


3.0            Responsibilities


3.1              Anyone at Jefferson Lab:

·         If you see or produce a chemical spill contact:

o   Security at x5822, or

o   Request assistance from the Hazardous Waste Coordinator at x7882.


3.2              Chemical Worker

·         Know the location of the Chemical Spill Kit(s) in your area; how, and when to use it.

·         Read and understand the Operational Safety Procedure written for the specific area(s) you are assigned to perform work.

·         Ensure the required training is current.

·         Read and understand the MSDS of the product in use.


3.3              Hazardous Waste Coordinator

·         SOTR for the cleanup vendor

·         Provide chemical waste disposal assistance.


3.4              Area Supervisor

·         Ensure Chemical Spill Kit(s) are adequately stocked with appropriate supplies; are accessible; and chemical workers know their location, how and when to use it.


4.0            Process Steps


If there is personal over-exposure to a chemical, 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              Chemical Spills


Step 1:             Note the material, location, and quantity.


Step 2:             Protect yourself and others in the area outdoors evacuate 100ft upwind Indoors evacuate the room, and close all doors.


Step 3:             Call Security (x5822) immediately and give them 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.


Small drips/non-hazardous spills can be cleaned up by users and or trained individuals. Large spill cleanup (> drips, hazardous chemicals) must be coordinated by the hazardous Waste Coordinator and vendor.



(Spill kits are available in every work area where hazardous chemicals are used or stored in quantities greater than 1 gallon (4 liters).)  Contact the Hazardous Waste Coordinator (x7882) if a Chemical Spill Kit is needed or supplies need review.


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


Area specific work control documents (e.g., Operational Safety Procedure) describe the specific activities and chemical spill procedures for those in affected areas.

4.2              Waste Clean-up and Disposal


Contact the Hazardous Waste Coordinator (x7882) to remove waste and other suspect material left after completion of clean-up procedure(s).
