_______ is defined as an applied force or system of forces that tend to either strain, or deform a container or trigger a change the condition of the contents. There are three types.
Stress
- Thermal
- Mechanical
- Chemical
Disintegration
Runaway cracking
Failure of container attachments
Container punctures
Container splits or tears
Five basic types of breach
Detonation
Violent rupture
Rapid relief
Spills, or leaks
Four types of release
______ simply refers to the effects of exposure to the hazardous material and/or its container
Forms are (T-TRACEM)
Thermal
Toxicity/poisons
Radiation
Asphyxiation
Corrosivity
Etiologic
Mechanical
Harm
When developing the incident action plan, most operations will begin from a ______ point of view
Defensive
A narrow, split or brake in the container metal which may penetrate through the container metal. It is a major problem that could cause catastrophic failure.
Crack
Reduction in the thickness of the container shell. It is an indentation in the show me by relatively blunt object. Some are caused by prolong contact with a tank car wheel called wheel burns.
Score
Reduction in the thickness of the tank shell it is an indentation made by a sharp chisel like object
Gouge
Reduction in the thickness of a railroad tank shell it is similar to score, but is caused by prolong contact with a turning rail car wheel
Wheel burn
A deformation of the tank, head or shell it is caused from impact with a relatively blunt object. The sharper the radius of the curvature of this, the greater chance of cracking
Dent
Hey, deformation in the shell of a railroad tank car it is actually a long dent with a gouge at the bottom of the N-word dent. This can occur circumferentially or longitude in relation to the tank shell. The longitude ones are the more serious. This is generally caused by the tank car, passing over a stationary object, such as a wheel flange or rail.
Rail burn
A deformation in the shell of a highway cargo tank it is actually a long dent is inherently flat generally caused by a container overturning and sliding some distance along a cement or asphalt road
Street burn
