  • The ERG is composed of

    color-coded sections.

    The blue and yellow sections help the officer

    identify the material

    the orange section provides

    response guidelines related to Potential Hazards, Public Safety, and Emergency Response.

    DOT has established the

    United Nations/North American (UN/NA) four-digit numbering system to identify materials.

    An officer may be able to identify a material using the ERG by finding any one of the following:

    โ€ข the four digit number on the placard or orange panel on the container
    โ€ข the name of the material on the shipping papers or packaging
    โ€ข the number of the material on the shipping papers or packaging

    The Public Safety section

    contains information on notification, protective clothing, and evacuation.

    The notification subsection

    identifies what officers must do immediately when called to a scene, such as activate agency emergency response plans and ensure help is on the way.

    Additional information can be gained from

    calling the emergency contact number on the shipping papers or the emergency response telephone numbers
    listed inside the guide's back cover.

    After an officer isolates the immediate danger area, the next step is to

    evacuate or protect people in the downwind hazard area or within the radius of the incident.

    protective action distance

    how far people should stay from a spill

    An officer can establish an Initial Isolation Zone and then a

    Protective Action Zone to prevent people from being exposed in a downwind hazard area.

    Evacuate the area if the incident is going to

    last for an extended period or could potentially cause a fire or explosion.

    Fire creates the potential for an

    explosion or a boiling liquid expanding vapor explosion
    (BLEVE).

    (BLEVE).

    boiling liquid expanding vapor explosion

    Emergency Response this section has three subsections:

    Fire; Spill or Leak; and First Aid.

    The fire subsection

    provides guidelines to all levels of responders. Awareness-level responders must not attempt to extinguish a fire that involves hazardous materials. Normal fire extinguisher
    training is not sufficient to fight a fire that directly involves hazardous materials. Only properly trained and protected people should attempt to fight such a fire. Operational level personnel with the necessary protection and training can accomplish defensive fire attack. Technician-level personnel must conduct an offensive fire attack.

    The ERG gives in-depth

    information about proactive action distances.

    Geographical conditions

    can also affect the distribution of any hazardous materials

    operational-level personnel can perform

    spill control if they avoid direct contact with the material and have proper protection. they can also activate the remote shut-off.

    Technician-level responders can

    perform leak control

    The first aid subsection outlines

    basic first aid for victims of exposure. Awareness level

    Encourage contaminated, conscious victims to move to an

    isolated area and await medical assistance from properly trained and protected personnel.

    OSHA regulations mandate a structured termination process, the THREE steps are

    1 on-scene debriefing
    2 incident critique
    3 and after action analysis

    On-scene debriefing process:

    officers are advised of the materials to which they may have been exposed, signs and symptoms of exposure, and who to contact if they notice signs and symptoms of exposure.

    if exposure exceeds the acceptable published limits,

    the officer is sent for medical evaluation

    During the critique phase

    officers provide information on operational Strengths and Weaknesses.

    In the after-action analysis the agency's goal is to

    review any weaknesses and implement any additional or corrective training, as necessary.

    Meth Lab

    locations where methamphetamine is manufactured

    meth labs are not

    scientific laboratories in the tradition sense

    a meth lab can be as small as a

    soda bottle and as large as a warehouse.

    methamphetamine is manufactured by

    converting pseudoephedrine or ephedrine through a simple chemical process.

    The observation of precursors or materials used may be indicators that

    an meth lab exists.

    dangerous chemicals found in meth can be found anywhere in a

    home, vehicle, vessel, shed, motel, or other location.

    The materials used are readily available items such as

    coffee filter, two-liter bottles, blenders, lithium batteries, red-tipped matches, cold tables, camp stove fuels, drain cleaners, brake fluid, and bleach

    common methods used in the manufacture of meth are the

    One pot "shake and bake" method, the red phosphorous method, and the "Nazi" (anhydrous ammonia) method.

    meth labs may produce strong chemical odors like

    rotten eggs or cat urine, and have surrounding areas of dead vegetation.

    ingredients used to produce meth are typically

    flammable, volatile explosions, or toxic gases.

    if a officer suspects the a lab is present

    they should avoid inhaling fumes, making contact with the chemicals, or turning anything on or off.

    meth labs can also be

    booby traps.

    Decontamination protocol for a meth lab incident is the same as

    for any hazmat exposure

    evacuate the occupants and

    leave the premises immediately

    chemical suicide

    also known as: "DETERGENT SUICIDE" is a method of committing suicide by mixing two or more easily acquired chemicals, commonly an acid and a base.

    chemical suicide: Once MIXED:

    these chemicals produce gases that quickly fill an ENCLOSED area. these incidents occur in vehicles, closets, bathrooms, or other small, confined spaces where the concentration of gas can quickly accumulate to lethal levels.

    the most common methods of chemical suicide is

    1 Hydrogen sulfide
    2Hydrogen Cyanide

    during a chemical suicide DO NOT

    attempt to enter the area, or rescue or resuscitate the individual

    Indicators of chemical suicide

    ~unresponsive or sleeping person in a vehicle
    `warning signs taped to doors or windows
    ` unusual odors such as rotten eggs, sulfur, or burnt almonds
    ` suicide note inside the vehicle
    ` pennies in the area tarnished with residue
    ` yellow-green or white residue on vehicle seat, dashboards or windows
    ` household cleaning or pesticide containers
    ` buckets for mixing chemicals
    ` a vehicle's inside door handles removed
    ` tape or towels sealing a door or air vents
    ` a bag over the subject's head

    exposure to chemical suicide: MILD EXPOSURE-

    irritates the eyes, nose, and throat.

    exposure to chemical suicide: MODERATE EXPOSURE-

    headaches, dizziness, nausea, vomiting, coughing, and difficulty breathing.

    exposure to chemical suicide: HIGH EXPOSURE -

    severe respiratory irritation, severe eye irritation, convulsions, coma, and death.

    chemical weapons are capable of causing mass casualties because

    a small amount of agent can be SPREAD OVER A LARGE AREA. they can be used to target HUMANS as well as PLANTS and ANIMAL LIFE.

    use of chemical weapons can result in

    the destruction of FOOD CROPS, WATER SOURCES, DEATH OF ANIMALS

    chemical weapons present a danger that is much more harder to identify than

    conventional explosives

    chemical weapons may release gases or aerosols that are not recognized upon

    exposure or shortly after

    examples of chemical WMD

    nerve agents, and chlorine.

    primary indicator or chemical exposure is

    the RAPID onset of symptoms.
