Study Notes
Mop-Up Operations in Firefighting
- Mop-up is necessary after a fire is declared "Under Control" to ensure safety and extinguish lingering fire embers.
- The primary goal is to prevent any fire from crossing the established fire line.
- Mop-up begins independently once the fire spread is halted, following the completion of line construction and burnout.
Key Actions in Mop-Up
- Initiate mop-up immediately after completing line construction and burnout, prioritizing the most threatening areas.
- Allow fuels to burn naturally if it is safe and expedient to do so.
- For small fires, all burning materials should ideally be extinguished.
- In large fires, extensively mop up around the fire line to prevent potential fire spread under extreme conditions.
- Actively search for and address smoldering spot fires to prevent flare-ups.
Fuel Management
- Smoldering materials should be extinguished or dispersed well within the fire line to avoid ignition.
- Remove or relocate less flammable fuels, like rotten logs and snags, that are near but outside the control line.
- Burned trees that can emit sparks or fall across the line must be eliminated within the line.
Safety Measures
- Manage rolling materials to ensure they are positioned safely away from crossing the fire line.
- Look for signs of hot spots such as swarming gnats, white ash, the presence of pinholes in the ground, and indicators from wood-boring insects.
- Use water effectively; applying Class A foam can enhance the extinguishing capability for deep-seated fuels.
Command Considerations
- Command should define the area within the control line that needs to be overhauled; this may encompass the entire burn area for smaller fires.
- At least two firefighters should stay on-site during mop-up crew rehabilitation to monitor for re-ignition risks.
- Follow-up checks should be scheduled to ensure the effectiveness of mop-up operations in preventing fire resurgence.
