pressure relief devices and/or damaged fittings

oxidizers, corrosives, cement, plastic pellets, and fertilizers
How can you visually identify a low pressure tank car - ✔️✔️cylindrical with rounded ends
Why does an evacuation zone tend to be large when dealing with an incident involving a
pressure tank car - ✔️✔️Capacities are large, exposed to heat or flame they will fail
catastrophically, ERG gives initial isolation zone of 1 mile
How long is a cry tank designed to protect contents from ambient temp - ✔️✔️Up to 30
days
Where are railcar reporting marks located - ✔️✔️Both sides and both ends
What info does the capacity stencil give - ✔️✔️Amount of product
Where can you find specification markings - ✔️✔️Both sides of tank (opposite from
reporting marks)
What makes intermodal containers so efficient for shopping - ✔️✔️Can be used
