Protective Actions
Those steps taken to preserve the health and
safety of emergency responders and the public
during an incident involving releases of
dangerous goods
4-44
45Table of Isolation Protective Action Distances
Isolate hazard area deny entry
1. Keep everybody away from the area if they are
not directly involved in emergency response
operations 2. Isolate first (to establish
control over the area of operations)
4-45
46Table of Isolation Protective Action Distances
Evacuate
To move all people from a threatened area to a
safer place
1. Begin evacuating those nearby those outdoors
in direct view of the scene 2. Expand the area
down wind and cross wind using Guidebook
recommendations

GASES TOXIC FLAMMABLE (EXTREME HAZARD)
ERG2004
SPILL OR LEAK
- ELIMINATE all ignition sources (no smoking,
flares, sparks or flames in immediate area). - All equipment used when handling the product must
be grounded. - Fully encapsulating, vapor protective clothing
should be worn for spills and leaks with no fire. - Do not touch or walk through spilled material.
- Stop leak if you can do it without risk.

GASES TOXIC FLAMMABLE (EXTREME HAZARD)
SPILL OR LEAK
- Use water spray to reduce vapors... Avoid
allowing water runoff to contact spilled
material. - Do not direct water at spill or source of leak.
- If possible, turn leaking containers so that gas
escapes rather than liquid. - Prevent entry into waterways, sewers, basements
or confined areas. - Isolate area until gas has dispersed.
- Consider igniting spill or leak to eliminate
toxic concerns.
