A recent fire in a commercial building, triggered by a combination of equipment malfunction and exposure to hazardous materials, offers a stark reminder of how quickly small defects can escalate into serious incidents. In many cases, the root causes are familiar: missed inspections, overdue servicing, poor housekeeping, inadequate control of contractors, and gaps in emergency procedures. In high-occupancy environments such as office blocks and retail units, where uptime and public safety are paramount, these weaknesses represent unacceptable risk to people, property and reputation.

Commercial buildings are complex systems. Heating, ventilation and air-conditioning (HVAC), electrical distribution, lifts, emergency lighting, smoke control, fire detection and suppression, generators, cradles, mobile elevating work platforms (MEWPs), rope access systems, and specialist plant all interact. A single failure—an overheated motor, a loose connection, a clogged filter, a neglected extract duct—can become the initiating event that, combined with flammable vapours, dusts or incompatible chemicals, leads to ignition and rapid fire spread. Effective equipment maintenance and disciplined hazardous materials management are therefore not optional extras; they are a critical layer of protection.

Facilities managers and duty-holders under UK health and safety law carry legal and moral responsibilities to ensure plant is safe, maintained, and used by competent persons. Insurers increasingly expect evidence of structured maintenance regimes and robust contractor management. The lesson from recent incidents is clear: prevention through planned maintenance and rigorous controls is far less costly than response and recovery.

Best Practice Equipment Maintenance in Commercial Environments

A resilient maintenance regime blends statutory compliance, manufacturer guidance and risk-based priorities. Consider the following principles as a baseline for office and retail estates:

  • Build a complete, accurate asset register. Include make, model, serial number, location, criticality, maintenance intervals and statutory obligations. Keep drawings and O&M manuals easily accessible.
  • Implement a planned preventative maintenance (PPM) programme aligned to recognised standards such as SFG20, manufacturer schedules and insurers’ requirements. Calibrate the programme by asset criticality and risk.
  • Meet statutory inspection duties. Examples include:
    • Electrical fixed-wire testing (in line with BS 7671 and the Electricity at Work Regulations).
    • Portable appliance testing (risk-based).
    • LOLER thorough examinations for lifting equipment and accessories (e.g. cradles, davits and anchor points used for façade access).
    • Pressure systems written schemes of examination.
    • Gas Safe servicing of gas appliances.
    • Fire detection, alarm, emergency lighting and suppression system testing in line with relevant British Standards.
  • Embed isolation and permit-to-work controls. For intrusive or higher-risk tasks (e.g. hot works, electrical isolations, roof plant interventions), use clear permits, lock-off/tag-out devices, and supervision.
  • Keep plant rooms clean and orderly. Remove combustibles, maintain clear access/egress, protect escape routes, and ensure ventilation pathways are unobstructed.
  • Monitor condition and performance. Use trend data from BMS/SCADA, vibration/thermal imaging for critical motors and switchgear, and oil analysis where appropriate. Early detection prevents failure.
  • Manage change. When plant is modified, relocated or replaced, update the asset register, maintenance tasks, risk assessments and emergency procedures.
  • Document everything. Maintenance records, defect logs, remedial close-outs and certificates form the evidence trail for regulators, insurers and your own assurance.
  • Coordinate with operations. Schedule PPM and statutory inspections to minimise disruption but avoid deferring critical tasks. Out-of-hours work should include robust lone working and emergency arrangements.
  • Pay special attention to high-risk systems. Kitchen extract ductwork requires routine cleaning to reduce grease fire risk; fire and smoke dampers must be inspected and tested; UPS and battery rooms require temperature control and fire detection; façade access systems require regular inspection and, where applicable, independent anchor testing.

A disciplined maintenance programme reduces the likelihood of ignition sources, controls fuel loads, and ensures safety systems function as intended if an incident occurs.

Emergency Response Preparedness: From Paper Plans to Practised Behaviour

No maintenance regime removes risk entirely. When incidents occur, outcomes depend on how well occupants and responders execute a plan under pressure.

  • Maintain a current fire risk assessment. The Responsible Person must ensure risks are identified and proportionate controls are in place under the Regulatory Reform (Fire Safety) Order 2005 and subsequent updates. Review after any significant change or incident.
  • Develop and communicate an Emergency Response Plan. Define alarm activation, evacuation strategies (e.g. phased, simultaneous, or stay put where applicable), assembly points, roles and responsibilities, and how critical plant is shut down safely.
  • Train and drill. Fire wardens, facilities teams and reception/security staff require initial and refresher training. Conduct regular evacuation drills, including variations for out-of-hours and contractor presence. Use debriefs to drive improvement.
  • Plan for vulnerable persons. Prepare Personal Emergency Evacuation Plans (PEEPs) and ensure refuges, evacuation chairs and intercoms are functional and staff are trained.
  • Integrate systems. Test the interfaces between fire alarms, smoke control, lifts, access control, generators and BMS to confirm intended behaviour during alarms.
  • Prepare for chemical exposures and spills. Equip relevant areas with spill kits, eye wash stations and clear instructions. Train staff to respond safely without improvisation.
  • Coordinate with emergency services. Share building plans, hazardous material inventories and access arrangements with the local fire and rescue service where appropriate. Conduct familiarisation visits for complex sites.
  • Test communications. Confirm alarms, PA, radios and cascaded notifications work under real conditions, including in basements and plant rooms.
  • Learn and improve. Use a Plan-Do-Check-Act cycle. Capture near misses, test findings and incident learnings, assign actions with deadlines, and monitor close-out.

Preparedness turns a written plan into a lived routine, reducing confusion and accelerating safe evacuation and response.

Handling Hazardous Materials: Protocols that Prevent Incidents

The recent incident underscores how hazardous substances can amplify the consequences of an equipment fault. A robust approach is essential, even in buildings that are not primarily industrial.

  • Maintain an up-to-date hazardous materials inventory. Include cleaning chemicals, gases, solvents, batteries, refrigerants, oils, aerosols and any contractors’ materials temporarily on site.
  • Conduct COSHH assessments for all substances used and stored on site. Ensure Safety Data Sheets (SDS) are available, current and understood by users.
  • Apply DSEAR where flammable liquids, gases, vapours or combustible dusts are present. Control ignition sources, provide adequate ventilation, and classify hazardous zones where necessary.
  • Store safely. Segregate incompatible chemicals, use appropriate cabinets for flammables and corrosives, keep quantities to the minimum needed, and never store chemicals or batteries in escape routes.
  • Control lithium-ion battery risks. Designate charging areas with good ventilation, avoid overnight or unattended charging where possible, use manufacturer-approved chargers, and provide suitable fire detection and suppression for battery storage.
  • Manage refrigerants and F-gases. Use certified personnel for handling; maintain leak detection systems; keep plant rooms tidy and ventilated; record movements for compliance.
  • Protect against legacy hazards. Maintain an asbestos register and management plan; brief all staff and contractors; use licensed professionals for intrusive works.
  • Provide spill prevention and response. Secondary containment for drums and IBCs, drip trays for plant, clear signage, and trained responders with PPE prevent escalation.
  • Dispose of waste correctly. Use licensed carriers, segregate waste streams, and ensure hazardous waste consignment notes are retained.
  • Train and supervise. Only competent, authorised persons should handle hazardous substances; provide refreshers and toolbox talks tailored to site-specific risks.

By integrating hazardous materials control with equipment maintenance and housekeeping, facilities reduce both the likelihood and severity of fire and exposure incidents.

The Role of External Contractors in Compliance and Safety

External contractors are integral to maintaining complex buildings, from façade access and window cleaning to specialist inspections and plant servicing. They can either strengthen your safety culture or expose you to avoidable risk. Selecting and managing the right partners is critical.

  • Verify competence and accreditations. Look for evidence such as ISO 9001 (quality), ISO 14001 (environment) and ISO 45001 (occupational health and safety) certifications; membership of relevant professional bodies; and third-party approvals like SafeContractor or CHAS. For high and difficult access, IRATA-qualified rope access technicians, IPAF-trained MEWP operators, and proof of LOLER-compliant equipment are essential.
  • Demand robust RAMS. Require detailed, site-specific risk assessments and method statements that reflect your building’s unique hazards, including fire strategies, occupancy patterns, and any hazardous materials present.
  • Control access through permits to work. Use permits for hot works, roof access, electrical isolations, confined spaces and any activity that could affect life safety systems. Ensure isolation points, alarm interfaces and emergency contacts are clearly identified.
  • Induct and communicate. Provide thorough site inductions covering fire procedures, assembly points, asbestos registers, hazardous substance controls and welfare arrangements. Confirm contractors know how to call for help and how to stop work if conditions change.
  • Coordinate and supervise. Appoint a competent person to oversee contractor activities, avoid clashes with other high-risk work, and monitor standards in real time. Short, targeted toolbox talks at the start of each shift reinforce expectations.
  • Audit and review. Include contractors in safety audits and inspections. Monitor KPI performance (e.g. close-out of remedial actions, permit compliance, housekeeping) and take corrective action promptly.
  • Expect year-round diligence. For services such as window and façade maintenance on high-rise buildings, insist on safe access planning (water-fed pole systems, cradles, MEWPs or rope access as appropriate), current equipment inspections, weather monitoring protocols and public protection measures. Regular external cleaning and inspection can also reveal early signs of building fabric defects, blocked drainage or plant exhaust issues that, if ignored, may contribute to overheating, contamination and fire risk.

For facility operators in London and the South East, partnering with experienced, safety-led contractors provides assurance that maintenance tasks are executed efficiently and compliantly, even on tall or architecturally complex structures. Competent providers bring not only trained personnel and specialised access capabilities but also the management systems, documentation and culture that support your legal duties and protect occupants.

In summary, the critical importance of equipment maintenance in commercial buildings cannot be overstated. Recent fire incidents remind us that reliability, safety and reputation are built day by day through planned maintenance, disciplined hazardous materials control, well-practised emergency response, and strong contractor partnerships. By investing in these fundamentals—and continually verifying their effectiveness—duty-holders can prevent accidents, minimise disruption and maintain safe, welcoming environments for staff, customers and the public.
