Question 46

# Define: 1. TIH 2. Initial Isolation Distance 3. Protective Action Distance

Answer 46

1. Gases or volatile liquids that are toxic when inhaled! Includes certain warfare agents and water reactive materials which produce toxic gases upon contact with water. 2. Initial isolation distance is the distance (radius) which defines a circle in all directions from the actual spill/ leak source. 3. Protective action distance is the downwind distance from the actual spill/leak source within which protective actions could be implemented.
