1 1 Hazardous Materials Section Four: Planning and Implementing a Response Analyze Plan Implement Evaluate

2 2

3 3 Identification  No action should take place until the identity of the hazardous material is confirmed  Identification tools:  Placard/Markings/Labels/704 Diamond  Shipping papers  DOT-ERG  MSDS  NIOSH Guidebook  CHEMTREC

4 4 NIOSH Pocket Guide September 2005

5 5 NIOSH Contents  Roman numeral pages contain information keys  Multiple opportunities to indentify chemical  Name, Chemical Abstracts Services (CAS) #, Synonym/trade name list  Affords responders more detailed information to assist in planning  Use after material identification and DOT-ERG application

6 6

7 7 Identification  When researching a chemical use readily available resource information sources  DOT-ERG/NIOSH Pocket Guide/MSDS  Consult at least three different sources if possible  On-scene research should continue throughout the incident

8 8 Identification  After identification, operations-level responder should ONLY perform DEFENSIVE actions that do not involve contact with the material  If unable to identify:  The most conservative response strategy and tactics must be employed  Use DOT-ERG Guide 111

9 9 What to Report  Report the information clearly, concisely, and accurately  An error in spelling, an incorrect measurement, a mispronunciation of a chemical name, or incorrect identification of a hazardous material can be disastrous

10 10 What to Report  Keep information as simple as possible  Spell names that are complex or potentially confusing  Ethanal or ethanol?  Have the receiver of the information repeat back what was heard

11 11 What to Report  Information to report includes:  Exact address and location of spill or leak  Identification of indicators and markers of hazardous materials  All color and class information obtained from placards

12 12 What to Report  Four-digit UN/NA numbers  Hazardous material identification obtained from shipping papers or MSDS and the potential quantity of hazardous material involved  Description of container, including size, capacity, type, and shape  Amount of chemical that could leak and amount that has leaked

13 13 What to Report  Exposures: Of people and the presence of special populations (children/elderly) Environment of the immediate area  Current weather: Including wind direction and speed  A contact: Or callback telephone number and two-way radio frequency or channel

14 14 Plan an Initial Response  The first priority is the safety of responding personnel  Responders are there to isolate the problem, not to become part of it  Proper incident planning will:  Keep responders safe  Provide a means to control the incident effectively, preventing further harm to persons or property

15 15 Plan an Initial Response  Planning response options begins with:  Preplanning and SOG’s (your best tools)  Followed by the initial call for help  Information is used to determine the safest route to the scene

16 16 Plan an Initial Response  Choose a route that approaches the scene from an upwind direction whenever possible  Choose a route that places the responders uphill of the site

17 17 Plan an Initial Response  Responders need to know the type of material involved  Is the material a solid, liquid, or gas?  Is it contained in a drum, barrel, or pressurized tanker?

18 18 Plan an Initial Response  Response to hazardous material spill  Releases will differ from solid-liquid or gas

19 19 Plan an Initial Response  A solid is local and can be easily contained*  A gas can be widespread and constantly moving depending on the gas characteristics and weather conditions * Unless it is a dust or small particles

20 20 Plan an Initial Response  Characteristics of the affected area near the location of the spill or leak are important factors in planning the incident response  If an area is heavily populated:  Evacuation procedures and a decontamination process need to be established very early in the incident

21 21 Plan an Initial Response  If the area is sparsely populated and rural:  Isolating the area from anyone trying to enter the location may be the top priority  A high-traffic area such as a major highway would necessitate immediate rerouting of traffic

22 22 Plan an Initial Response  There may be more than one way to solve the problem  A thorough risk based response analysis must be performed  There are times when no action may be the safest course of action

23 23 Plan an Initial Response  Understand product control options  Identify physical and chemical properties of the released substance  Decontamination should be performed when and where appropriate

24 24 Planning a Response  Incidents may be categorized by SOG:  Level One: Small product release/no life-environmental hazard  Level Two: Special resources needed/local area/moderate environmental impact potential  Level Three: Uncontrolled release/large area evacuation/severe environmental impact possible

25 25 Tier Response 1- TOMs Unit (ORU Optional) (5 Techs) 2- TOMs Unit & ORU (1/2 Team) 3- TOMs Unit & ORU(s) (Full Team) 4- Multi-Team 5- Full Hazmat System, plus Bomb Squad and CST activated Situation Hazard & Risk Assessment or Suspicious Substance Investigation Short Term Entry Operation Long Term and/or Immediate Life Safety Risk Major Release or Extended Operation WMD or Mass Casualty Event Massachusetts Chemical/Radiological/Biological Incident Response Activation Levels

28 28 Response Objectives  Operations-level responders develop defensive, non-product contact objectives  Some effective defense actions can be taken safely at a distance

29 29 Defensive Objectives  Isolate the area affected by the leak or spill  Evacuate victims who could become exposed  Control where the spill or release is spreading  Confine the spill to a specific area

30 30 Defensive Actions  Diking and damming  Absorbing or adsorbing material  Stopping the flow remotely from a valve or shutoff  Diluting or diverting material  Suppressing or dispersing vapor

31 31 Proper Personal Protective Equipment  PPE is needed based on the hazardous material involved  Physical/chemical properties  At a minimum, fire fighters should wear full protective gear with no skin exposed and use SCBA  Standard structural firefighting PPE offers limited hazardous material protection

32 32 Identify Emergency Decontamination Procedures  There must be a procedure or a plan in place to decontaminate any responder who accidentally becomes contaminated  Victims removed from a contaminated zone must be decontaminated  Personnel who perform decon need to be trained in proper decon methods Rapid Access Mass Decontamination (RAM Decon)

33 33 Gauging the Potential Harm or Severity of the Incident  Based on the toxicity and the concentration of the hazardous material, responder may be able to gauge how the incident might progress

34 34 Resources for Determining the Size of the Incident  DOT-ERG  Identifies and outlines predetermined evacuation distances and basic action plans, based on spill estimates, for thousands of chemicals  Computerized or hard-copy pre-incident plan  Includes reports submitted to the fire department and topographical mapping information

35 35 Reporting the Size and Scope of the Incident  Reporting the estimated incident size is done by using information available at the scene  If a container (vehicle) is transporting a known amount of material, the size of the release may be estimated  Units can be as small as square feet or as large as square miles

36 36 Determine the Concentration of a Released Hazardous Material  How may an OLR determine a material’s concentration?  Litmus paper use is not an OLR action  Monitoring instruments are used to analyze the atmosphere from a safe distance

37 37 Determine the Concentration of a Released Hazardous Material  Once the concentration is known, the IC can evaluate the incident response plan  A high concentration of an acid would call for a high level of PPE  May also require the evacuation of civilians

38 38 Incident Command System  Consists of five functions:  Command/Operations/Planning/Logistics/Finance  ICS can be expanded to handle an incident of any size and complexity  Hazardous materials incidents can be complex  Local, state, and federal responders and agencies will be involved in many cases of long duration

39 39 Incident Command System  It is Federal Law that an ICS must be used at all hazardous materials incidents  A written incident action and site safety plan must be developed for the incident  A special technical group, under the Operations Section, called a Hazardous Material Branch, may be developed for the incident

40 40 Incident Command System Haz-Mat Branch Operations Section Science Unit HM Safety Officer Entry Group Decon Group Entry Unit B/U( RIT) Unit

41 41 The Command Post  The main hub of the ICS  ICP is the collection point for all information and resources  Must be located in the cold zone upwind and upgrade from the spill or leak to keep it from becoming contaminated

42 42 The Command Post  If the ICP and personnel became contaminated, the personnel would no longer be able to control the operation  The command post could be as close as one block away or as far as miles away from the hot zone

43 43 Summary  An important early notification to make is the request for additional response personnel, hazardous materials response teams staffed by trained technicians, and technical specialists  The approach to the incident should be from upwind, and from a direction that ensures that released liquids and/or vapors flow away from responders  Possible defensive actions include stopping the release with a valve or shutoff; absorbing, adsorbing, diking, damming, diverting, or diluting escaped material; and suppressing or dispersing vapor

44 44 Summary  The type of personal protective equipment required depends on the material involved and the nature of the incident  The Incident Command System must be used at a haz-mat incident  In a hazardous materials incident, a Hazardous Materials Branch develops under the Operations Section in the Incident Command System
