General rule for EMS in hazardous material
|
High index of suspicion and stay away.
|
50.4
|
|
|
EMS's job in Hazardous material
|
If first on scene try and identify material looking for labels, placards, driver, transportation papers, etc. Identify and notify. Leave and wait for scene to be "secure." Try and control others/civilians entering if possible.
|
50.5
|
|
|
What book do you look in to figure out what the four-digit number means on the placards?
|
The US Department of Transportation's Emergency Response Guidebook (ERG)
|
50.7
|
|
|
What should be carried with the driver or conductor about the hazardous material?
|
The driver should have a bill of lading.
The conduct should have a waybill. |

|
The NFPA Hazardous Material Classifications
|
Level from 0 to 4 from least to most dangerous.
Blue is health hazard. Red is fire hazard. Yellow is reactive hazard. |
|
|
|
Hazardous PPE Level A
|
Level A provides the greatest exposure from hazard, containing a SCBA along with "fully encapsulated."
Monitor for heat stress |
50.10
|
|
|
Hazardous PPE Level B
|
Suit used for protection from splashes and inhaled toxins. It is not fully encapsulating like Level A. Includes a SCBA. Typically worn in a decontamination team in the warm zone.
|
50.10
|
|
|
Hazardous PPE Level C
|
Protection against a known agent, providing splash protection, and a air filtration for the known agent.
|
50.10
|
|
|
Hazardous PPE Level D
|
Protection offer by fire fighters' turnout. May be used by some personal in the cold zone.
|
50.10
|
|
|
Primary contamination
|
The direct exposure of a pt to a hazardous material.
|
50.11
|
|
|
Secondary contamination
|
When a hazardous material is transferred to a person from another person or from contaminated objects. Most common with solids and liquids left on patient's clothing or skin.
|
50.11
|
|
|
vapor pressure
|
The pressure exerted by a vapor when the liquid and vapor states of a material are in equilibrium; this measure changes as a material is heated.
|
50.20
|
|
|
vapor density
|
A measure that compares the hazardous material gas to air, air being 1. If the toxic gas is heavier than air > than 1 it will sink. If the toxic gas is lighter than air < than 1 it will dissipate above the air.
|
50.20
|
|
|
flash point
|
The temperature at which a hazardous material will ignite by a spark.
|
50.13
|
|
|
ignition temperature
|
The temperature at which a vapor will burst into sustained burning.
|
50.13
|
|
|
lower explosive limit
|
The concentration of the hazardous material that can burn or explode in the air when mixes with air.
|
50.20
|
|
|
upper explosive limit
|
The concentration of a hazardous material at which there is not enough oxygen to support the combustion in air.
|
50.20
|
|
|
water soluble
|
A property that indicates that a material can be dissolved in water.
|
50.20
|
|
|
specific gravity
|
Same principle as vapor density, but in terms of liquid to water.
|
50.20
|
|
|
parts per billion
|
The unit of measurement that is often use to express various substances concentration as safe or unsafe.
|
50.13
|
|
|
threshold limit value
|
The concentration of a substance that is supposed to be safe for exposure no more than eight hours per day and forty hours per week.
|
50.20
|
|
|
What are the types of decontamination methods?
|
Dilution-flushing with copious amounts of water.
Absorption-Pads soak up the hazard to remove if from the pt, ie towels. Neutralization-The use of chemical to change the hazardous material into a less harmful substance. Disposal-ie clothing and equipment. |
50.13-14
|
|
|
Treatment consideration for a patient involve in hazardous material
|
Avoid invasive procedures as they provide a route of exposure. Weigh the risk and benefits.
|
50.15
|
|
|
Corrosives
|
Acids and bases that cause severe burns. Tx is often flushing. May react with water. Stop the burning.
