Hazardous Materials tech mfri review____is the most common exposure route and often the most dangerous. -
ANS-Inhalation
Absorption through the ____ is one of the fastest means of exposure due to the high
absorbency rate - ANS-eyes
acute effects - ANS-results from a single does or exposure to a material. signs and
symptoms may be immediate or may not be evident for 24 to 72 hours after exposure
acute emergency exposure guildlines - ANS-developed by the National Research
Council's Committee on Toxicology to provide uniform exposure guidelines for the
general public
acute exposure - ANS-an immediate exposure, such as a single does that might occur
during an emergency response
Alpha particles - ANS-larges of the common radioactive particles. Travel 3 to 4 inches.
stopped by piece of paper or skin
Although certain situations may exist where decontamination may affect victim care or
further delay primary treatment, as a rule of thumb all victims should receive -
ANS-gross decontamination
Although there are three ERPG Tiers, the ____ level is the most commonly cited
guideline when using public protective action decision making support tools -
ANS-ERPG - 2
An atmospheric concentration of any toxic, corrosive, or asphyxiant substance that
poses an immediate threat to life or would cause irreversible or delayed adverse health
effects, or would interfere with an individuals ability to escape from a dangerous
atmosphere - ANS-IDLH
Any means available should be used to cool the victim, the body temperate should be
taken at 5 minute intervals and should not go below 1 - ANS-101 F
At incident where an HMRT is operating, safety responsibilities will often be divided into

number of hazmat emergencies while serving as a member of a public safety HMRT of
conducting on-scene investigations of hazmat incidents over many years
concentration guidelines for singer exposure to hazardous materials developed by the
American Industrial Hygiene Association as an emergency planning tool for public
protected action options - ANS-Emergency Response Planning Guildlines
Concentration x time = - ANS-Dose
developed through a US EPA National Advisory Committee, these are intended to
provide uniform exposure guidelines for the general public for single short- term
exposure - ANS-Acute Emergency Exposure Guidelines
Dose/Response Relationship - ANS-the cause / effect relationship relating to a
substance absorbed by the body and the body's response to the substance
Emergency Response Planning Guildlines - ANS-air concentration guidelines for single
exposure to hazardous materials
Events created by uncontrolled exposure to living microorganisms - ANS-Etiological
Harm
Events related to chemical burns and or tissue damage from exposure to corrosive
chemicals. - ANS-Corrosive Harm
Events related to emission of radiation energy - ANS-Radiation Harm
