Bagaimana cara melakukan rescue dari ketinggian untuk tower crane operator?

Tower crane operator bekerja 30-80+ meter - jika terjadi injury atau medical emergency di cabin, rescue sangat challenging dan time-critical.

Emergency Scenarios Requiring Rescue:

• Medical emergency: Heart attack, stroke, severe injury
• Fall arrest event: Operator fall tapi caught oleh harness - suspension trauma
• Equipment failure: Stuck di cabin, cannot descend
• Fire: Escape route blocked
• Unconscious: Heat stroke, toxic exposure

Suspension Trauma (Critical Concern):

Jika operator fall dan tergantung di harness:

• Blood pools di legs - gravity + harness constriction
• Reduced blood return ke heart dan brain
• Unconsciousness dalam 10-20 min
• Cardiac arrest possible jika suspended >30 min
• Rescue shock: Sudden horizontal positioning after rescue can cause cardiac arrest

PRE-PLANNING (Before Emergency Occur):

1. Site Emergency Response Plan

• Every site dengan tower crane MUST have rescue plan
• Plan include:
• Rescue team designation
• Equipment inventory dan location
• Step-by-step procedure
• Communication protocol
• Ambulance access route

2. Rescue Equipment Staged

• At base of crane:
• Rescue harness dan ascender
• Rescue stretcher (vertical lift type)
• Rope, carabiner, pulley system
• First aid kit, AED, oxygen
• Two-way radio
• In cabin (jika possible):
• Rescue descender device
• Emergency supply kit

3. Trained Rescue Team

• Minimum 3 personnel trained di height rescue
• Annual training dan drill
• Certified dalam rope rescue technique

4. Communication System

• Direct radio contact operator-ground
• Backup communication (phone, visual signal)

EMERGENCY RESPONSE PROCEDURE:

Phase 1: ALERT (0-2 min)

1. Distress call: Operator radio for help (jika able)
2. OR: No response: Ground crew notice operator tidak respond ke radio call
3. Activate emergency:
• Alert site emergency coordinator
• Call ambulance - "Medical emergency at height, tower crane"
• Mobilize rescue team
• DO NOT send untrained person up

Phase 2: ASSESSMENT (2-5 min)

• Establish communication jika possible:
• Radio call - assess operator condition
• Visual from ground dengan binocular - operator moving?
• Determine scenario:
• Conscious atau unconscious?
• Inside cabin atau suspended outside?
• Equipment operational atau failed?
• Decision tree:
• Operator conscious, mobile: Talk down dengan instruction
• Operator conscious, immobile: Assisted descent
• Operator unconscious: Full rescue required

Phase 3: RESCUE EXECUTION

Scenario A: Self-Rescue (Operator Conscious, Mobile)

• Radio instruction untuk operator:
1. Stay calm, assess own injury
2. If minor - can descend dengan guidance
3. Ensure harness attached, use fall protection selama descent
4. Medical personnel meet at bottom

Scenario B: Assisted Rescue (Operator Conscious, Needs Help)

1. Rescue climber ascend:
• Experienced climber dengan rescue training
• Full PPE, harness, rescue equipment
• Continuous radio contact dengan ground
2. Reach operator:
• Assess condition, provide first aid jika possible
• Attach rescue harness jika needed
3. Descent method:
• Operator ambulatory: Assist descent dengan supervision
• Operator cannot walk: Use rescue stretcher

Scenario C: Full Rescue (Operator Unconscious)

1. Two rescuer ascend (minimum):
• Primary rescuer + backup
• Stretcher, medical kit, rope system
2. Reach operator, immediate care:
• Check airway, breathing, circulation
• CPR jika needed (challenging di height!)
• Attach rescue harness
• Secure operator ke stretcher
3. Lower operation:
• Rigging setup untuk controlled descent
• Ground crew operate lowering system
• Rescuer accompany operator during descent
• Slow, controlled - prevent swing/impact
4. Ground medical:
• Paramedic ready at landing point
• Stretcher transfer ke ambulance
• Medical protocol: Keep semi-reclined 20-30 min before full horizontal (prevent rescue shock)

Special Technique - Suspension Trauma Relief:

Jika operator suspended di harness awaiting rescue:

• Self-rescue loop:
• Carry webbing loop di harness
• Stand on loop - take weight off leg straps
• Restore circulation, delay trauma onset
• Rescuer action:
• Attach support untuk operator leg ASAP
• Allow standing position

Post-Rescue:

• Medical evaluation - hospital transport mandatory even if seem okay
• Incident investigation
• Crane inspection before return to service
• Psychological support untuk operator dan rescue team

Training Requirements:

• All tower crane site must have rescue capability
• Rescue drill annually minimum
• Operator should practice self-rescue technique

Height rescue is specialized skill - rely on trained professional, not improvisation!
