Poor detector maintenance linked to gas explosion risk
Crowcon Detection Instruments has warned that businesses relying on gas detection units without maintaining them could face major safety risks.
The company said many firms assume installation alone ensures compliance, but devices that are not tested, calibrated or serviced can fail when needed most.
Crowcon pointed to the BP gas explosion in Texas as an example of how poor gas monitoring can worsen an incident.
The hydrocarbon vapour release killed 15 workers and injured more than 170.
The company explained that the tragedy demonstrated how neglected systems can contribute to wider safety failures.
Crowcon highlights dangers of neglecting gas detectors
Ed Clapham, Product Manager at Crowcon Detection Instruments, said: “Many businesses mistakenly think that gas detection installation alone is enough to meet compliance requirements.
“But it’s important to understand that this equipment is not just a fit-and-forget solution.
“Detectors need to be maintained, calibrated and tested regularly so they function properly in situations where lives may depend on them.
“Unlike visible hazards, gas leaks are often invisible and odourless, and without properly maintained detectors, workers may not realise they are at risk until it’s too late.
Clapham added that neglected or poorly maintained detectors expose businesses to worker safety threats, operational disruption and reputational damage after avoidable incidents.
He said: “Poorly maintained or neglected detectors create multiple vulnerabilities.
“These include threats to worker safety, operational disruption and reputational damage following avoidable incidents. It can also erode trust among employees.
“Beyond that, businesses may face fines and enforcement action if detectors are not fully functional. Industry legislation makes it clear that employers have a duty of care not only to install gas detectors but also to keep them in working condition.”
Maintenance and calibration key to compliance
Clapham explained that gas detectors rely on components that can drift over time, making calibration essential to ensure accuracy.
He said: “Maintenance and calibration aren’t just about ticking compliance boxes.
“Gas detectors rely on components that can drift over time, affecting performance, safety and reliability.
“Calibration keeps readings accurate, while testing and maintenance ensure sensors, alarms and batteries are functioning correctly.
“This helps identify faults before they turn into safety risks.”
He added that routine servicing should be treated as a core part of any workplace safety programme.
Crowcon outlines key steps for detector upkeep
Clapham has provided several recommendations for ensuring gas detectors remain reliable.
He advised businesses to create a maintenance schedule based on manufacturer guidance and local environmental conditions.
He also said workers should be trained to recognise detector faults, low battery warnings and operational alerts.
Regular refresher sessions are important, especially where staff turnover is high.
Clapham recommended contacting accredited third-party providers for calibration, servicing and repairs where in-house capacity is limited.
He also advised maintaining a log of each detector’s service and test history to track performance and detect recurring issues.
Relevance for fire and safety professionals
The information from Crowcon Detection Instruments is relevant to fire safety officers, risk assessors and facility managers across industrial, energy and commercial sectors.
Gas detection is a frontline control measure in many high-risk workplaces, and failures in maintenance can result in undetected leaks leading to gas explosions or toxic exposure.
The company’s warning underlines the importance of ensuring detectors remain fully operational through calibration, testing and staff training.
Regular device maintenance schedules and accurate service records can help prevent incidents while ensuring compliance with occupational safety regulations.
