6 Minutes for Safety: HAZARD TREE - RISK MANAGEMENT

HAZARD TREE - RISK MANAGEMENT

Situational Awareness/ Hazard Assessment

Environment:
  • Existing winds and forecast.
  • Night operations.
  • Steep slopes.
  • Diseased or bug-kill areas.
  • Number, density, and height of hazard trees. 
  • Anticipated burn-down time.
  • Potential for domino effect to surrounding trees.
  • Maintain situational awareness and continually reassess hazards. 

Hazard Tree Indicators:

  • Trees burning for any period of time.
  • High risk tree species (rot and shallow roots).
  • Numerous downed trees.
  • Dead, broken, or burning tops and limbs overhead.
  • Accumulation of downed limbs.
  • Absence of needles, bark or limbs.
  • Leaning or hung-up.
Note: In addition to suppression and mop-up operations, assess, control, and monitor hazard  trees along roads and when selecting break areas or campsites.

Hazard Control:
  • Eliminate the hazards with qualified sawyers, blasters/explosives, or heavy equipment. 
  • Avoid hazards by designating “No Work Zones” (NWZ) – (flag, sign, and map). 
  • Modify suppression tactics or fire-line location to avoid extreme/high risk rated area. 
  • Post lookouts to help maintain secure area.
  • Fire proof potential hazard trees to  prevent ignition.
  • Initiate road/traffic control and area closure. 
  • Keep clear of bucket drops near trees/snags. 
  • Establish trigger points for re-position to secure areas in response to high winds.

Growing numbers of communities, across the nation, are experiencing longer fire seasons; more frequent, bigger, and more severe, fires are a real threat. Be careful with all campfires and equipment.
