Q

When setting up the BA Entry control point (ECP)
What five things do you need to considering where to place it?

A
  1. As close to the incident as possible (but still maintaining safety.
  2. In safe air
  3. In such a position that, should the incident deteriorate, it will not be necessary to move.
  4. A focal point so that the ECO is easily located by all BA wearers
  5. One ECP can cover more than one entrance to risk area

Q

Duties of BA ECO

A
  • ECO board, tabard and maker
  • take up position as nominated by IC
  • name, stage, and entry control point
  • synchronise clocks
  • receive tallies, check name and cylinder contents
  • enter ‘time in’ on each tally
  • enter tallies and bracket, overwrite tallies with names and set numbers
  • work out time of whistle - also elapsed time if From initial deployment.
  • identify team leader in ‘“ location of team’ column
  • indicate location of team
  • Comms check and maintain comms with BA team
  • initial deployment or Re Entry in remarks
    -Return tallies to BA wearer on exit and recurve a concise debrief
17
Q

Criteria for stage 1

A
  • The nature of BA operations is limited and not complex
  • The incident requires no more than one BA entry control point
  • The incident requires no more than 6 VA wearers
    BA Guidelines are not required
18
Q

Rapid deployment entry control procedures apply where:

A
  • IC carries out a suitable and sufficient assessment of the risks versus the likely benefits
    -resources available are limited
  • A crew member, this may be the OIC, will be made responsible for monitoring the BA team.
  • opportunity to preserve life or take action that will prevent an incident deteriorating
  • as soon as resources became available, stage 1 BA Entry control procedures must be implemented as a minimum level of control.
  • BA Wearers will ensure tallies and gauges are checked and that tallies are placed in the BA Entry control board, with ‘ time in’ recorded by themselves and through an automated board.
  • no more than two BA wearers will be in the risk area.
