The unique fire risks in waste and recycling
Combustible materials and spontaneous ignition
Waste management facilities often contain numerous materials that are highly combustible and can lead to spontaneous ignition. The processing of wood based materials such as paper can create fine dust that is explosive when suspended in the air. All it takes is a single spark to ignite these materials and create a dust explosion that rapidly spreads fire throughout the facility.
Harsh operational environments and deep-seated fires
Fires in waste management facilities often start deep within a waste pile. This allows them to smoulder and escalate undetected. Some fires can go days without being detected, by which point they are extremely well established and difficult to suppress. There is also the chance that such deep-seated fires will reignite easily too.
Navigating complex regulations and compliance
There are unique waste site fire safety compliance challenges that make staying fully compliant more difficult. Due to their ever-changing environment, it is very difficult to accurately assess the fire risk within a waste management facility. This is because the fuel load within a facility is constantly changing which requires an assessment to provide fixed safety parameters that account for a highly variable fire load that can include any number of highly flammable and combustible materials.
The potential for the risk of spontaneous combustion must also be addressed in an assessment. This drives the need to establish (and enforce) heat temperature monitoring, safe pile size limits, and material rotation as part of the fire safety procedures.
Specialised detection and suppression systems must be used to remain fully compliant, and there are specific separation and storage requirements provided by Waste Industry Safety and Health (WISH) that must be followed.
The role of the responsible person and WISH guidelines
The role of the responsible person (RP) is to ensure waste site fire safety compliance and minimise the risk of fire and injury. To do this they need to run regular Fire Risk Assessments (FRA), implement fire safety measures based on the FRA findings, conduct adequate fire safety planning and training, ensure all fire safety assets are maintained and tested, and keep detailed records of all training, maintenance and procedures.
There are WISH guidelines that are specifically aimed at fire safety within waste management facilities. They include guidance on the maximum recommended size, height, and separation distances for stored waste piles to reduce the chances of fire risk, ignition source control through material rotation and temperature monitoring, firewater runoff containment planning to avoid pollution, and the recommendation to use advanced detection methods that can detect heat at the centre of a waste pile before smoke is visible.
