BACO meaning

BACO (Breathing Apparatus control officer) is the designated person who establishes and manages breathing apparatus entry control at an incident or hazardous workplace, recording and supervising all wearers, calculating duration and turn‑back times, maintaining tallies/telemetry, coordinating emergency teams and communications, and liaising with the Incident Commander. The role underpins accountability and safe systems of work for firefighting, confined space operations and other respiratory‑protective work. The term is not defined in legislation or case law; it is an operational description used across fire and rescue services and industry, often interchangeably with Breathing Apparatus Entry Control Officer (ECO). Usage and function are broadly consistent across England and Wales, Scotland, Northern Ireland and Ireland. In legal practice, BACO procedures are relevant to compliance and evidence under health and safety duties (for example, Health and Safety at Work legislation, the Confined Spaces Regulations 1997 (GB), the Confined Spaces Regulations (Northern Ireland) 1999, and the Safety, Health and Welfare at Work (Confined Spaces) Regulations 2001 (Ireland)). BACO records (control boards, logs, telemetry) and training/competence commonly feature in regulatory investigations, enforcement actions, inquests/fatal accident inquiries, civil claims and contractual obligations (method statements, risk assessments, and CDM‑related documentation).
