Response to Chemical Releases


    Spill Response
    Module 10



                                1
Overview

   Spill containment and remediation activities shall be
    directed in such a way that the protection of human
    life, health, and safety is paramount.
   Some of the general guidelines in handling a
    disaster or emergency response includes:
       Use of the incident command system.
       Using proper PPE, incorporation of the buddy system,
        designation of a safety officer.
       Following the ten steps to a safe response, and use of
        appropriate decontamination procedures.

                                                                 2
Terminal Learning Objective


    Participants will be able to
     implement procedures used in
     disaster response for releases
     and spills of hazardous materials.



                                          3
Introduction
   Spill containment and remediation activities shall be
    determined and directed by the Incident Commander at
    the scene of an incident. These activities will be directed
    according to the following priorities:
       Protection of human life, health, and safety.
       Mitigation of environmental harm.
       Protection of property.




                                                              4
Levels of Response

   Limited to defensive action whenever possible.
   Limited to training, resources, and personnel.




                                                     5
Response Guidance

   Use the ICS.
   Identify all hazards.
   Get help from specialist employees.
   Use proper PPE.
   Do not come into direct contact with the
    hazardous substance.

                                               6
Response Guidance

   Use the “buddy system”.
   Use SCBA.
   Have backup.
   Designate a Safety Officer.
   Maintain contact and communications.
   Use appropriate DECON.


                                           7
Factors Affecting the Behavior of
Released Hazardous Material

   Quantity of the hazardous material.
   Inherent properties of the material and of
    the container.
   Natural laws of physics and chemistry.
   The environment, including physical
    surroundings and conditions (ventilation,
    sources of ignition, etc.).
                                                 8
Prepare a Plan of Action

   Each step in the response
    needs to be planned carefully.
    Accidents are most likely to
    occur when drums and
    containers are being handled
    for the first time in an
    emergency.



                                     9
    Handling Drums and Containers

   When responding to an emergency,
    move drums or containers for only
    these reasons:
       Gain access to other drums or
        containers that are leaking or failing.
       Prevent injury to responders and
        support personnel because drums or
        containers are stored improperly or
        located in remote areas.
       Prevent reaction with spilled or leaking
        materials.

                                                   10
Handling Drums and Containers

   When handling drums and containers
    be prepared for additional spills.
       Absorbents

       Diking material

       Salvage or overpack drums


                                         11
       Handling of Drums or Containers
       OPEN AND DETERIORATED DRUMS OR
         CONTAINERS CONTAINING LIQUID
   Transfer contents to a new or reconditioned drum.

   Bond and ground drums when transferring flammable
    or combustible liquids.

   Start transfer with full drum first.




                                                        12
Handling Open and Deteriorated Drums

   If the drum cannot be moved without danger
    of it breaking open, immediately transfer
    contents to a new or reconditioned drum
    using a transfer pump.
   Use pumps designed for the class of liquid
    to be moved.




                                                 13
Using Overpack or Salvage Drums

   Record all label information
    from damaged drum.
   Record other useful
    information such as location
    and contents.
   Certify overpack drum is
    compatible with contents of
    damaged drum.
   Prepare label for the overpack
    drum.
                                     14
    Drum and Tank Repair
   Before proceeding with drum repair,
    make sure proper PPE and
    equipment are used and leaking
    from the drum has stopped.
   If leaking has not stopped, position
    the drum so the leak is above the
    liquid line.
   Lock the drum in position with wood
    blocks.
   Use a temporary plug or patch to
    contain leaking material.

                                           15
    Drum and Tank Repair

   Plugs, patches, and combinations of the
    two, make effective repairs.
       Plugs can be wooden wedges, screws
        with washers, tubeless tire plugs,
        toggle bolts with washers, and
        expandable plugs.
   Patches include metal tapes, epoxy
    sealers, and mastic materials.
       Patching can be accomplished by
        wrapping the drum in banding material
        such as rubber or neoprene and
        holding it in place with a metal plate.


                                                  16
Absorption Methods

   Floor Dry
   Sand
   Diatomaceous Earth
   Polypropylene
   Hazorb
   Vermiculite
   Activated Carbon
   Spill Pillows

                         17
Gel Forming Agents




                     18
Vapor Suppression
   Vapor from hazardous spills is suppressed by
    applying a foam blanket over the spill in a
    contained area.
   It is less effective if liquid is not contained and
    not effective if liquid is flowing.




                                                          19
Summary

   Response activities will be directed according
    to the following priorities:
       Protection of human life, health and safety.
       Mitigation of environmental harm.
       Protection of property.
   Teams should observe general guidelines
    when handling a response to chemical
    releases.
