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:
• the four digit number on the placard or orange panel on the container • the name of the material on the shipping papers or packaging • 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).

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.
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.
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
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
Decontamination protocol for a meth lab incident is the same as
for any hazmat exposure
evacuate the occupants and
leave the premises immediately
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
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.
