Hazmat Army

DOT used to cover 9 classes

EPA

EPA / must be reported

EPA / regulated under RCRA

OSHA / risk to employee

UN model codes and regulations

OSHA / possess toxic, reactive, flammable, or explosive properties

anything designed to kill on purpose

major hazard = explosion

mass explosion hazard (TNT)

Projection hazard (aerial flares)

fire hazard with minor blast or projection hazard (propellant explosives)

minor explosion hazard with no blast or projection hazard (fireworks)

mass explosion hazard extremely insensitive (prilled ammonium nitrate with fuel)

extremely insensitive articles with no mass explosion hazard (squib)

major hazard = BLEVE

boiling liquid expanding vapor explosion

Flammable gas at 68 degrees (propane)

nonflammable, nonpoisonous / pressure of 40.6 psi or greater at 68 degrees (cryogenic argons)

Gas poisonous by inhalation / gas at 68 or les and a pressure of 14.7 psi (cyanide or chlorine)

flammable and combustible liquids

having a flash point of no more than 140 degrees (acetone)

flash point above 140 degree and below 200 degrees (diesel)

flammable solids and reactive liquids and solids

flammable solids including wetted explosives , self-reactive materials, readily combustible solids (magnesium pellets)

explosive properties suppressed by wetting with alcohol or water

materials liable to undergo a strong exothermic decomposition at normal or elevated temps due to high temperature

solids that can cause a fire through friction and any metal powders that can be ignited

spontaneously combustible materials with pyrophoric material or self-heating material (phosphorus)

a liquid or solid that can ignite within 5 minutes after contact with air

a material that when I contact with air is able to self heat

dangerous when wet materials (magnesium powder)

oxidizers and organic peroxide major hazard = combustion or intense fire

Oxidizer / a material that may, generally by yielding oxygen, cause or enhance the combustion of other materials

organic peroxide / any organic compound containing oxygen in the bivalent structure

can detonate or deflagrate rapidly as packaged for transport

neither detonated nor deflagrates rapidly, but that can undergo a thermal explosion

neither detonates nor deflagrates rapidly and cannot undergo thermal explosion

detonates only partially or deflagrates slowly, with medium to no effect when heated under confinement

neither detonates nor deflagrates and shows low, or no effect when heated under confinement

will not detonate, does not deflagrate, and shows only a low, or no, effect if heated when confined, and has low or no explosion power

will not detonate, does not deflagrate, shows no effect if heated when confined, and has no explosion power

poisons, poison inhalation hazard, and infectious substances

poisonous materials other than gases (tear gas

infectious substances (tetanus)

radioactive (uranium)

corrosive (sulfuric acid)

Miscellaneous

a material that presents a limited hazard during transportation due to its form

round / BLEVE concern / bolted man ways

refrigerated liquefied gas / highway cargo tank

spills is a concern / flat ends les rounded

drums and bottles / pneumatic loading and unloading

must be packages and transported according to strict regulations designed for protection / determined by type / industrial, excepted, type a, type b, type c

transport liquids and gases

each hazard class has a specific ___________ that identifies the material's class

________ are 3.9 inches square-on-point diamonds

descriptive name, number weight, or a specific, and includes instructions, cautions, or UN marks required on outer packaging of haz. materials

metal signs placed adjacent to and above a haz. materials ____________

used on fixed facilities, may be on vehicles, not uniform, not all hazmat will be marked

uses a rating system of numbers from 0 to 4 / ratings assigned to three categories: health , flammability, instability (W=reactive with Water / OX=indicates material is an oxidizer

uniform classification / uniform labeling standards

detailed info. bulletin prepared by a chemical's manufacturer or importer / located in central location where employees have easy access / standard 16 sections

follow ISHP sequence (I= ID number / S= proper shipping name / H= hazard class or division / P= packing group) / each mod of transport has specific place to carry these / CHEMTREC

air bill with pilot

Dangerous cargo manifest with captain or master

train list or way bill with conductor or engineer

Bill of lading or freight bill with driver

vapor cloud / unusual smoke color / flames / PPE fails / dying or discolored vegetation / container deterioration / containers bulging / sick people / dead animals

rainbow sheen / wavy vapors / for or ice buildup / containers that are deformed / activated pressure relief device

safest indicators

heat / unusual temp drop / fire conditions / peeling or discoloration / boiling / colored vapor clouds / smoking / peculiar smells / symptoms of chemical exposure

single exposure or several repeated exposures to substance within a short period

long term / reoccuring

Inhalation / ingestion / absorption / injection

energy release / corrosivity / toxicity

presents the greatest threat / heat, mechanical, pressure, electricity, chemical, radiation

open flames, smoking materials, cutting and welding ops., heated surfaces, frictional surfaces, friction, radiant, static, electrical, mechanical sparks

does not hurt body right way can occur hours to days later

Emergency Response Guidebook / helps to quickly identify hazards at a transportation site / ID numbers = yellow pages / reference the name = blue pages / materials transportation placard = front of book / reference container profile = white pages then orange bordered

Isolation / scene control / sheltering in place

use a vehicle to block roads / divert traffic / erect barricades / close doors and gates

defined in predetermined procedures

covered in departmental standard operating procedures / must be trained to use communication equuipment
