Q

The following elements are common to ‘’’ release:

Energy - generally travels a word in all directions

Dispersion of energy- affected by terrain cloud cover

Release-may propel the hazards material and container parts

166
Q

Other plume dispersion elements include:
PR
OR

A

Puff release- all the material at one time
Ongoing release- concentration increases overtime until the leak stops then decreases
