Smoke clearance checks

Certified, professional spraybooth smoke clearance testing across the UK. Available as standalone clearance tests or integrated into an annual spraybooth service and compliance plan.

We provide accurate, reliable smoke clearance testing to verify air exchange rates, determine safe re-entry times, and keep your operators protected. We ensure your workshop operates safely and in full compliance with HSE Guidance (HSG261), COSHH regulations, and insurance standards.

Why Smoke Clearance Times Matter

Paint sprayers are up to 80 times more likely to develop occupational asthma than workers in other sectors, primarily due to inhaling airborne isocyanates when a booth appears visually clear but still holds lingering, invisible paint mist. Smoke clearance testing uses non-toxic theatrical smoke to calculate exactly how long the extraction system takes to purge all airborne contaminants once spraying stops. Only after this calculated clearance time has elapsed is it safe for operatives to enter or remove air-fed respiratory protective equipment (RPE).

Visual Indication & Regulatory Sign-Off

Testing is conducted under realistic operating conditions (ideally prior to filter changes to reflect worst-case airflow) to accurately establish clearance intervals. Following testing, our engineers issue official compliance certification and supply prominently displayed clearance time indicator boards at every spraybooth access door—ensuring staff and visitors know exactly when entry is safe.

Streamline Your Audit: The All-in-One Compliance Visit

Avoid coordinating multiple contractors and paying separate call-out fees by bundling your legal safety checks into a single site visit. Our engineers can carry out your Quarterly Breathing Air Quality Check (BS EN 12021), Annual LEV Thorough Examination (COSHH Reg 9), and Spraybooth Smoke Clearance Time Test on the exact same day. We handle the scheduling, provide synchronized reminder alerts, and supply consolidated digital certification to keep your workshop audit-ready at lower overall cost.
