  1. Name the 7 clues to the presence of hazardous materials?
    • 1. Occupancy, locations, Pre-incident surveys
    • 2. Container shapes
    • 3. Placards, labels, markings
    • 4. Other markings or labels
    • 5. Written Sources
    • 6. Senses
    • 7. Monitoring or Detection devices
  2. Types of containers?
    • Bulk and Non-Bulk-refers to capacity
    • Pressure and Non-Pressure-refers to design based on onternal pressure
    • Bulk capacity fixed facility contaiment systems and transportation packaging-refers to facility or mode
  3. To be classified as Bulk capacity one of these 3 conditions must be met
    • Maximum capacity is greater than 119 gallons as a recepticle for a liquid
    • Maximum net mass is greater than 882lbs or 119 gallons as a recepticle for a solid
    • Water capacity is 1,001 lbs or greater as a recepticle for a gas
  4. In general above ground storage tanks are divided into two major categories
    • Non pressure tanks(atmospheric tanks)
    • Pressure tanks
  5. Charecteristics of Non-pressure/Atmospheric tanks
    • small amount of pressure
    • up to .5 psi
  6. Pressure tanks are divided into two categories
    • Low pressure storage tanks- have pressures between 0.5 psi and 15 psi
    • Pressure vessels- pressures above 15psi
  7. Common types of Non-pressure/Atomspheric pressure tanks are? (5)
    • 1. Horizontal tanks
    • 2. Ordinary cone roof tanks
    • 3. Floating roof tanks
    • 4. Lifter roof tanks
    • 5. Vapordome roof tanks
    • note: a properly designed and maintained tank will fail along the shelf to top seam
  8. Common types of Pressure tanks are?(6)
    • Dome roof tank
    • Spheroid tank
    • Noded spheroid tank
    • Horizontal pressure vessel
    • Spherical pressure vessel
    • Cryogenic-Liquid storage tank
  9. Bulk transportation containers can be divided into 3 categories, name them?
    • Tank cars(rail)
    • Cargo tank trucks(highway)
    • Intermodal containers(highway,rail or marine vessel)
  10. Tank cars are further divided into 3 categories, name them?
    • Low-pressure or general service(nonpressure tank cars)
    • Pressure tank cars
    • Cryogenic liquid tank cars
  11. also; hopper cars, box cars, flat cars etc...
  12. Low Pressure tank cars(rail)
    • transport haz + non haz w/ vapor pressure below 25psi at 105F-115F
    • tank test pressures are between 60 and 100psi
    • capacities range from 4k to 45k gallons
    • cylindrical w/ rounded ends, atleast 1 manway, fittings found on top or bottom w/ up to 6 compartments
  13. Describe Pressure tank cars(rail)
    • Typically transport flammable and non flammable liquids and poisons at pressure greater than 25psi at 68F
    • greater than 25psi @ 68F
    • Test range 100 to 600 psi
    • capacity 4k-45k gallons
    • cylindrical, noncompartmentalized w/ rounded ends, toploading, fittings are protected in a housing, typically none in sight
  14. Define Cryogenic Liquid tank car(rail)
    • Carry low pressure(below 25psi)
    • refridgerated below -130F
    • fittings etc. all ground level
    • tank within a tank, spaces filled w/ insulation+ vacuum, protected from ambient temperatures for only 30 days
  15. Define Intermodal Containers(used interchangeably)
    • Freight Containers-transport wide variety of products, most commonly 20, 40, 45, 48, and 53 ft lengths
    • Tank Containers- (aka intermodal)- low pressure intermodal, pressure intermodal, specialized intermodal
    • typically do not exceed 6,340 gallons
    • Low pressure-most common, sometimes called nonpressure, but may have pressures up to 100psi
  16. 2 common groups of low/non pressure tanks are?
    • IM 101 portable tanks- Built to withstand a working pressure of 25.4 to 100 psi
    • IM 102 portable tanks- designed to handle maximum allowable pressures of 14.5 to 25.4psi
    • (flammables with flash points between 32 and 140F)
  17. Describe pressure intermodal tank
    • less common
    • designed to working pressures of 100 to 500psi
    • usually transports liquified gases under pressure
  18. Describe specialized intermodal tanks
    • Several types(cryogenic)
    • tube high pressure 3,000 to 5,000psi
  19. Vessel cargo carriers are estimated to carry what % of world cargo?
    90%
  20. 3 types of vessel cargo carriers
    • 1. petroleum- size 200ft 15,000 barrell; size 1200ft 3,680,000 barrell
    • 2. chemical-30 to 58 tanks; each own pump; "floating drug store"
    • 3. liquified flammable gas carriers(LNG/LPG)
    • typically 500 to 900ft, 50 to 130ft in beam and depth of 40 to 60ft

    Rail
    Water
    • Air Bill=cockpit
    • Bill of lading= cab
    • trainslist=engine or caboose
    • dangerous cargo manifest=bridge or pilot house
  25. Which of the senses is definitely the safest to use in detection of a hazardous material?
    Vision
  26. Emergency Response Guide(ERG)
    yellow pages are in what order?
    Blue pages are in what order?
    What are the orange pages for?
    What are the green pages for?
    • Yellow is set up by number
    • Blue is set up by name
    • Orange is for Initial actions
    • Green is for Initial isolation distances for materials that produce toxic gases upon contact with water
    • Small spill < 53 gallons
    • Large spill > 53 gallons
    • If 30 mins have passed ERG doesn't apply
