EXTINGUISHING THE DELTA SHAKE AND SHINGLE LANDFILL FIRE
In British Columbia the Delta Shake and Shingle Landfill Fire
heightened the awareness of risks associated with fires at poorly
managed construction waste landfills and the financial burdens placed
on society once fires get out of control. Key lessons that were
learned from the fire were:
- Uncontrolled deposition and
poor waste poses an extreme fire hazard.
- Spontaneous combustion did occur
at Delta Shake and Shingle and presents the most likely triggering
mechanism for landfill fires at these facilities.
- Soil berm fire guards around
the horseshoe were effective in containing the fire to the horseshoe.
Refuse should be placed in cells not exceeding $10,000 to 20,000
m(3) and each cell should be fully encapsulated with 0.6 m of
inert soil material, not ground wood waste.
- Excavation of shallow trenches
that did not fully penetrate the refuse provided ineffective.
Trenches should be excavated only if they can penetrate through
the full thickness of refuse to inert material.
- Strict enforcement of regulations
is required to ensure poorly managed landfill operations are
shut down before large liabilities are accrued.
- Fire insurance should be a mandatory
requirement at all construction demolition landfill sites.
