BA Entry Control Board

BA Control Course Introduction

Breathing apparatus control procedures have been developed to ensure the following details are being recorded:

  • Name of wearer
  • Cylinder pressure of wearer
  • Time the wearer entered the risk area
  • The location of the wearer
  • The nature of the work or tasks being undertaken by the wearer

From this a safety attendant can work out the safe time of return of the wearer by calculating the working duration and anticipated time of whistle. The time of whistle is the moment when the wearers low pressure warning whistle will start to sound. The TOW can be determined by referencing either written duration tables or by the use of a duration calculator.  This training course ensures that control operatives can correctly operate these procedures to ensure the safety of breathing apparatus wearers.

BA Control Course Design.

The Breathing Apparatus Control Course is designed and structured to fully comply with the Department for Communities and Local Government document Operational guidance Breathing Apparatus.

The course is intended for anyone required to safely control the use of breathing apparatus.

This training is delivered as part of Confined Space Training Courses but is offered here as “Stand Alone” training for:

  1. Initial training
  2. Refresher training
  3. Qualification update from Medium Risk Confined Space to High Risk Confined Space

BA Control Course Content

The course consists of three sections:

  1. Theory/Knowledge teaching session:
    • The factors to consider when selecting BA control equipment.
    • Design and layout of entry control boards
    • Responsibilities of entry control operatives
    • Responsibilities of BA wearers in relation to entry control procedures
    • Function and operation of duration calculators.
    • Calculation of working duration for a variety of cylinder pressures
    • Recognise the compression factor when calculating full duration and working duration for 300bar cylinders
    • Understand the effects of hard work or other factors that influence working duration.
    • Understand the need for recording location and and other relevant information
    • Be aware of the need for effective communications
    • Operate the control procedures in conjunction with other safety systems such as confined space entry premits
    • Be aware of emergency procedures
      –  Actions to take on hearing the sounding of a DSU
      –  Failure to return by TOW
    • Be aware of RIDDOR legislation and the need to maintain records
  2. Practical instruction session:
    • Trainer to demonstrate:
      –  Operation and use of Dorset calculator or other duration tables
      –  Time of whistle calculations for individual wearers
      –  Completion of tally details
      –  Operation of control procedures
    • Imitation and practice of all of the above by candidate.
  • Practical Assessment session:
    • Control exercises under simulated emergency conditions.

BA Control Course Notes

  1. It is a legal requirement that all employees required to use the breathing apparatus receive training in safety control procedures.
  2. The training detailed on this page is “generic” breathing apparatus control training
  3. Training can be carried out at your premises provided suitable resources are available:
    • Sufficient space to accommodate course numbers
    • Space to use whiteboard, laptop and projector
    • External training area for practical training and exercises..
  4. We use standard entry control boards, Dorset duration calculators and BA Tallies for training.  
  5. We can design and deliver training for other manufacturers equipment.
  6. Specific training can be designed and delivered to meet your needs.
