COMAH sites don’t tolerate approximation. Detection has to be flame and aspirating rather than point smoke; door entry and readers in classified zones must carry ATEX ratings; suppression in control rooms and switchgear follows BS EN 15004 with six-monthly servicing. Compartmentation is the primary line of defence when vapour or thermal events outrun detection. We engineer to DSEAR zoning and keep the paperwork inspection-ready.
Fire alarms and evacuation, AOV smoke extract, disabled refuge and PAVA — designed, installed and maintained to current British standards, with monitored response when the alarm actually sounds.
Inert and chemical gas suppression — design, install, repair and maintenance for data centres, comms rooms and irreplaceable assets.
Fire doors, fire stopping, compartmentation, barriers and risk assessments — the protection that works without anyone pressing a button.
Intruder alarms, CCTV, access control, door entry and 24/7 monitoring — the systems that stay awake after the last person leaves.
AHU and ductwork install, service and repair, fire-damper testing, ventilation hygiene, AOV smoke extract, air conditioning and commissioning.
COMAH safety-report obligations · DSEAR zoning and ATEX equipment certification · Gas suppression for control rooms and switchgear on six-monthly service cycles · Perimeter CCTV and access segregation between safe and hazardous zones · Insurer scrutiny of compartmentation on high-hazard sites.
Every install is delivered to the relevant British / European standard with an audit-ready evidence pack at handover.
