Unit 5C Objectives

• 1. List four ways hand crews can be used in
  structure defense.
• 2. List three safety considerations when aircraft
  are used in structure defense.
• 3. Describe hazards commonly encountered by heavy
  equipmentoperations.

3
Hand Crews can be used to

• Construct handline
• Conduct site preparation
• Set up hose lays
• Support engine crews
• Conduct burn out operations
• Mop up and patrol

5C-3-S215-EP
4
ICS Hand Crew Types

• Type 1 18-20 people, experienced leadership,
  highly qualified, very physically fit, inter-crew
  communications, own transportation, saws
• Type 2 18-20 people, varying capability
  (experience, inter-crew communications,
  transportation, saws and physical fitness)

5
ICS Hand Crew Strike Team

• Minimum of 36 members including crew bosses.
• May have more more than 36, but not less than.
• Generally two crews is a strike team.

6
Hand Crews

• Order crews by ICS type based on complexity of
  fire.
• Extensive burnout and saw work order Type I.
• Type II crews are excellent for site preparation,
  supporting engine crews, and mopup. May take
  longer to dispatch (emergency hires).
• Check with crew boss regarding crews experience
  and training.
• Ensure crews have adequate transportation and
  communication.
• Communicate Escape Routes and Safety Zones.

7
Aircraft Operations

• Aircraft must be coordinated with ground units
  in order to be safe and effective!

Aircraft Operations

• Air Tanker Use Considerations
• Type, size, capabilities
• Availability
• Turnaround time
• MAFFS
• SEATs

12
Type 4 Air Tankers (SEATs)799 gallons or less
Example Air Tractor 802
01-12-S270-EP
13
Air tankers can drop water, foam or retardant

• Use retardant to pre-treat fuels near
  structures.
• Slow down fire advance for attack by ground
  forces.
• Coordinate drops with air attack or lead planes.
• Communication with aircraft is critical for
  safety.
• Use caution when dropping near crews, engines or
  structures.

15
ICS Types Helicopters Based on

• Payload capability or,
• Passenger capability or,
• Gallons of retardant/water

Bell Super 205

16
Type 1 Helicopters700 to 2,000 Gallons
Example Sikorsky S-64 Skycrane Useful in
stopping fire spread.
5C-16-S215-EP
17
Type 2 Helicopters300 to 700 Gallons
Example Bell 412 Useful in precision dropping
around structures.
5C-17-S215-EP
18
Type 3 Helicopters100 to 300 Gallons
Example Bell 206 B-III Jet Ranger
Useful for reconnaissance.
5C-18-S215-EP
19
Fixed Wing Aircraft

• Useful in reconnaissance, supporting operations,
  and air operations coordination (air tactical
  group supervisor)

02-19-S270-EP
20
Aircraft Coordination

• Ensure pilots have communication with ground
  forces.
• Only one person should be communicating with
  aircraft to direct water drops. (IAIC, DIVS or
  designated ground unit).
• Use large identifying landmarks to direct drops.
• Order aircraft early on, dont hesitate to order
  if you need them.

21
Aircraft Operations

• Retardant and Aerial Foam
• Long term retardant
• Short term retardant
  or foam
• Dont drop retardant
  on houses.
• Effectiveness depends upon prompt follow-up by
  ground forces.

03-21-S270-EP
22
Aircraft Operations

• Retardant and Aerial Foam
• None of the retardants,
  foam or water, applied
  from the air, can be
  counted on
  for total extinguishment.
  
• THEIR EFFECTIVENESS DEPENDS UPON
  PROMPT FOLLOW-UP BY GROUND
  FORCES.

23
Aircraft Operations

• Hazards
• Rotor wash and wind vortices
• The drop itself

24
Watch Out For Low Drops
03-24-S270-EP
25
If caught in retardant drop area

• Lie face down
• Hard hat (with chinstrap fastened) toward plane
• Hold tool on downhill side

Oncoming plane

26
Aircraft Operations

• Limiting conditions
• Power lines, wires and cables
• Wind exceeding 20 mph
• Visibility (smoke, fog, and inversions)

27
Heavy Equipment Operations

• Heavy equipment is best used to construct
  fireline for control or burnout.
• Heavy equipment has various capabilities and
  limitations.
• Heavy equipment involves unique hazards.

28
Types of Heavy Equipment

• Dozers
• Tractor plows
• Tractors with disks
• Road graders
• Construction/Logging

Heavy Equipment Safety

• Keep all personnel out of the vicinity of heavy
  equipment while working.
• Ensure that the equipment operator has required
  PPE, and communications with supervisor (usually
  Dozer Boss).
• Provide information on identified hazards to
  operator prior to beginning work.
