When setting up the BA Entry control point (ECP)
What five things do you need to considering where to place it?
- As close to the incident as possible (but still maintaining safety.
- In safe air
- In such a position that, should the incident deteriorate, it will not be necessary to move.
- A focal point so that the ECO is easily located by all BA wearers
- One ECP can cover more than one entrance to risk area
Duties of BA ECO
- 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
Criteria for stage 1
- 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 BA wearers
Rapid deployment entry control procedures apply where:
- 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.

Flashover signs and symptoms
- well ventilated free burning fire
- high heat conditions
- flaming combustion/ ghost flames overhead
- a sudden lowering of smoke layer
- rapidly rising temperatures possibility causing windows to fail

Growth phase
Fully developed phase
Decay phase
