Attn Compliance Managers: Why extraction system cleaning shouldn’t be the last thing on your list

For many Compliance and Facilities Managers, kitchen extraction systems sit quietly in the background of a building. They are out of sight, often out of mind, and usually only revisited when it is time to organise a scheduled clean or complete BWOF documentation. The problem is that extraction systems carry one of the highest fire risks in a commercial kitchen environment.

Every day, grease travels through the canopy, ductwork and fan system. Over time, that grease accumulates inside the ducting and on internal components. If it is not properly removed through regular, professional deep cleaning, it becomes highly flammable fuel running the length of the extraction system.

When a fire starts in an extraction system, it can spread rapidly through the ductwork and into the building structure. This is why New Zealand compliance frameworks place such strong emphasis on regular extraction system cleaning, documentation, and inspection.

For Compliance Managers responsible for BWOF sign offs and building safety, extraction maintenance should never be treated as a box ticking exercise. A visually clean canopy does not mean the system is safe. True risk mitigation requires internal cleaning of duct runs, fan housings, and discharge points where grease accumulates out of sight.

Regular professional cleaning does three important things:

• Reduces the risk of grease fuelled kitchen fires
• Ensures compliance with council BWOF requirements and standards such as SS9.
• Provides documented evidence that the system is being properly maintained

We are seeing councils and auditors placing increasing focus on extraction systems during compliance reviews. When documentation is missing or cleaning has been incomplete, the risk sits squarely with the building owner.

Extraction systems may be hidden infrastructure, but the risk they carry is very real. Keeping them properly maintained should sit high on every compliance manager’s priority list, not at the bottom of it.
