NFRC Joins Calls for Widespread Thermal Imaging for Roofing Contractors

ROOFING CONTRACTORS AND OTHER tradesmen carrying out ‘hot work’ should be using thermal imaging cameras to help reduce the number of fires caused, according to the National Federation of Roofing Contractors (NFRC).

Hot work, which includes grinding, welding and torching, is a major cause of blazes on construction and refurbishment sites, leading to millions of pounds worth of damage each year.

The NFRC, alongside insurer, Zurich, believes handheld thermal imaging devices, costing about £400, could help tackle the problem. It’s urging contractors on all non-domestic construction, refurbishment and maintenance projects involving hot work to consider adopting thermal cameras as standard.

Home Office data obtained by Zurich under Freedom of Information shows that between January 2015 and March 2019, fire crews in England attended 1,587 construction fires – of which 28% were caused by hot work, or other sources of heat.

Gary Walpole, Safety, Health & Environmental Officer at the NFRC, said, “The NFRC encourages the use of any technology that improves health and safety and within this guidance we recommend the use of thermal cameras, which are relatively cheap compared to the cost associated with fire, and the dangers posed to contractors and the general public.”

Kumu Kumar, Director of Risk Engineering for Zurich UK, said, “Fires caused by hot work have a devastating impact on lives, businesses and communities. The construction industry already has robust hot work controls in place but with fires continuing to break out, additional measures are urgently needed. Thermal cameras could further strengthen the industry’s existing safeguards and help to detect more hot spots before they ignite.

“The devices can also be used to take time-stamped photos to demonstrate fire watches have been carried out.  Although there is no single solution for preventing hot work fires, this is a relatively cheap and simple measure that could have a far-reaching impact, especially if the cameras are adopted as standard.”

Licensing and authorisation

Zurich is also calling for firms to adopt a voluntary licensing system that would see contractors complete a training course before carrying out or supervising hot work.

A similar ‘passporting’ approach has been in place in Scandinavian countries since the 1980s, where it has significantly reduced hot work fires to less than 5% of fires over the last decade. Contractors complete a one-day training course giving them a licence valid for five years.

Kumu continued: “As lessons from Scandinavia show, better training and awareness around pre-work assessments and post-work fire watch periods could help to dramatically reduce the frequency of fires sparked by hot work.  A passporting scheme also encourages best practice and provides peace of mind to businesses when choosing contractors.”
