Toxic/Poisonous Material and infections may cause thermal: products that are also flammable Chemical: toxicity by inhalation ingestion and skin and eye contact Etiological: either disease-causing organisms or toxins derived from living organisms
MC-306/DOT - 406 (Non-Pressurized)
Trucks transporting liquids at vapor pressure under 4 psig. Capacity up to 9,000 gal. - Fuel, Oil, Gas - Alcohol - Liquid Food Products - Flammable combustible liquids - Poisonous liquids *They have large oval ends*
Self Contained Breathing Apparatus (Closed Circuit)
Use of compressed oxygen or liquid oxygen rather than air. It last longer because it recycles exhaled air.
Vehicles, Transported Containers, Packages
Use the DOT placards, labels and identification number
Fixed Facility Containers
Use the NFPA 704 marking
MC-338 (Cryogenic Trucks)
Used to carry cryogenic liquids - Liquid argo - Liquid oxygen - Liquid nitrate * Has pressure range 25.3 - 500 psig. Capacity is 500 - 14,000 gal.*
Air line Respirators (Pros)
Useful during long duration hazmat incidents, decontaminations, or waste site activities. This advantage can become a disadvantage if it causes responder to "overwork"
Cloud
Vapor released in a single cloud. Complete release
Hemisphere
Vapor released that initially rises and spreads outward symmetrically. Occurs when there is no wind
Physical State
Wether solid, liquid, or gas. There are 6 states of changes. - Freezing - Melting - Condensation - Vaporization - Distillation: liquid - gas - liquid -Sublimation: solid - gas - liquid
Splits & Tears
When a seam or weld fails. Torn bags or split drum
Closure Opening
When discharge valve, safety valves or other closure applications break off
3rd Section of EPA registration number
Where product might be used.
Internal Stress
Within the Container
Long Term
Years and generations. Extensive clean up. Example is Chernobyl.
Analyzing The incident at operation level
You must not only recognize types of containers, labels, and marking but be aware of your surroundings. THINK ABOUT LAND!
Chemical splash protective clothing
designed to protect responders from contact with liquid chemicals. It does not protect against gases or vapors. Should not be used against liquids that give off vapor know to affect or be absorbed thru skin
Chemical Protective Clothing (CPC)
factors; -identify of the chemicals involved- physical chemical, and toxicological properties -Level of respiratory protection required - level of splash or vapor protection needed - protection against permeation, penetration, and degradation - potential for heat stress
Tank Cars
leased or owned by shipper. Marked on all 4 sides with a 3 letter abbreviation from the owner, followed by an "x" and number identifying the shipper and its content
Gases 2.2
non flammable gas has cylinder to represent compressed gas - Compressed gas - liquified gas - pressurized cryogenic gas - compressed gas in a solution
