Q

UNAFFECTED trains between stations should be moved to an UNCONTAMINATED STATION with entering contaminated areas

  • shut off HVAC system to prevent spread of contaminants
  • cover sidewalk gratins with tarps, sheets, plastic, rugs, etc.
  • shut down HVAC systems of all trains in contaminated area to prevent air intake of contaminants
A

if the chemical release occurs on TRAIN BETWEEN STATION

  • MTA will continue the train to the closest station and keep the train HVAC system on while in transit
  • receiving station should be evacuated prior to arrival of the contaminated train
  • train will be evacuated upon arrival and victims proceed to mass decontamination areas

Q

First Arriving Ladder Company…TEAM 1…EVHA

*if dispersal device is still operational, first alarm units shall make NO ATTEMPT to stop the device…responders shall immediately retreat and proceed directly to Gross Decontamination…Bunker gear is not satisfactory protection against the concentrations of agents

members operating in bunker gear, shall NOT PROCEED IN THE EXCLUSION ZONE ANY FARTHER THAN THE FARTHEST LIVE VICTIM WHEN PERFORMING HAZARD ASSESSMENT OR RESCUE OF AMBULATORY VICTIMS

A

Evacuation/Hazard Assessment - EVHA

  • Officer and 2 FF’s (do NOT enter subway where visible persons are unresponsive)
  • if members come across unresponsive victims, indicating life threat- notify IC AND RETREAT IMMEDIATELY TO BE DECONTAMINATED

Initial Hazard Assessment: if live victims can be seen/hear-make RAPID assessment (use route that does not impede the victims evacuation )

  • identify source
  • relay hazard assessment to IC

Evacuation:

  • direct victims to SAFE REFUGE AREA
  • assist evacuation-remove barriers/force gates
  • MARK ROUTE for CPC entry/rescue with SEARCH ROPES

Q

NST -Noxious Stimulus Triage…Victims response to….

A

voice/touch-likely to survive and should be REMOVED from area IMMEDIATELY

only pain-survival may be possible- but requires immediate ADVANCED medical treatment ( in a mass casualty incident the large number of victims may require that rescue efforts focused on saving those victims with a better chance of survival )

does not respond to pain- leave victim and proceed to next victim (not likely to survive)

deceased- left in place (UNLESS MOVEMENT OF SUCH VICTIM IS NECESSARY TO RESCUE ADDITIONAL VICTIMS OR TO MITIGATE HAZARDS)

27
Q

All chemical agents , EXCEPT HYDROGEN CYANIDE are HEAVIER THAN AIR .
