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
-
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
-
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
-
In general above ground storage tanks are divided into two major categories
- Non pressure tanks(atmospheric tanks)
- Pressure tanks
-
Charecteristics of Non-pressure/Atmospheric tanks
- small amount of pressure
- up to .5 psi
-
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
-
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
-
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
-
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)
-
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
also; hopper cars, box cars, flat cars etc...
-
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
-
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
-
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
-
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
-
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)
-
Describe pressure intermodal tank
- less common
- designed to working pressures of 100 to 500psi
- usually transports liquified gases under pressure
-
Describe specialized intermodal tanks
- Several types(cryogenic)
- tube high pressure 3,000 to 5,000psi
-
Vessel cargo carriers are estimated to carry what % of world cargo?
90%
-
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
-
Describe Intermediate bulk containers(IBC)
- Rigid or flexible packaging
- max capacity 793 gallons
- min capacity 119 gallons
- net mass not less than 882lbs
-

-
Air transportation=name+where
Highway
Rail
Water
- Air Bill=cockpit
- Bill of lading= cab
- trainslist=engine or caboose

-
Which of the senses is definitely the safest to use in detection of a hazardous material?
Vision
-
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
