Clean-up of Chemical Spills[1] Procedure



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.


For purposes of this appendix a “spill” is considered any quantity of chemical that an individual requires assistance, or special material/equipment, to mitigate a hazard issue.


This appendix is written in coordination with ES&H Manual 6610 Chemical Hygiene Program.  All applicable content within the chapter 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.


3.3              Hazardous Waste Coordinator

·         Provides spill response training and supplies as necessary. 

·         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 Emergency 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 and evacuate as necessary. 


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.


(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 emergency 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 Disposal

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


5.0            Revision Summary


Revision 1.2 – 06/28/13 – Triennial Review; added note of area specific WCDs.

Revision 1.1 – 03/30/11 – Removed reference to the Chemical Assistance Team.

Revision 1.0 – 07/05/10 – Updated to reflect current laboratory operations.
