Identify all the people who should be present at an incident debriefing - Hazmat Response Team, IMS
Officers, Incident Commander, Information Officers

following EXCEPT: - Thoroughly washing all parts with a chlorine bleach solution
When grounding a damaged tank, place the clamp: - Low enough on the grounding rod so that foam, if
used, will build up around the clamp
The object of bonding is to: - Keep objects at the same electrical potential, decreasing or eliminating any
chance of a static spark
When setting up a mass decon corridor, it should be located: - Upwind from the incident site
During an extensive decon operation, the step that would be performed just PRIOR to "SCBA Removal"
involving Level B protective clothing is: - Perform technical decontamination
When preparing to decontaminate, pay special attention to contaminants that can affect: - PPE and
monitoring equipment
Identify THREE emergency situations that can endanger the wearer of a CPC suit - Loss of suit integrity,

Ignition source and chemical compatibility
When using loading/unloading lines on a MC-360/DOT-306 cargo tank for a product transfer, be sure
that: - The unloading line is below the fuel level in the tank
Vent and burn operations are usually conducted by: - Container or product specialists

methyl ethyl badstuff leak. As a Technician-level responder, you should consider all of the following
tactical action options EXCEPT: - Plugging the hold in the drum
A site safety plan contains information specifically targeted at keeping responders safe - True
A typical plan of action is based on all of the following EXCEPT: - The Incident Commander's knowledge

All of the following factors should be considered when selecting the proper level of respiratory
protection EXCEPT: - The ability to refill SCBA cylinders
