Heavy equipment punya risiko tinggi kebakaran karena kombinasi fuel, hydraulic oil, electrical, dan hot components - operator harus competent menggunakan APAR.
Jenis APAR di Heavy Equipment:
1. ABC Dry Chemical Powder (Paling Umum)
- Effective untuk: Class A (solid), B (liquid), C (electrical)
- Kapasitas: Minimum 6 kg untuk equipment cabin
- Pro: Versatile, non-conductive (aman untuk electrical)
- Con: Residue merusak engine jika extensively used
2. CO2 (Carbon Dioxide)
- Best untuk electrical fire
- No residue - tidak damage equipment
- Con: Short discharge time, tidak untuk outdoor windy condition
Fire Classification:
- Class A: Solid combustible (seat upholstery, paper, rubber)
- Class B: Flammable liquid (diesel, hydraulic oil)
- Class C: Electrical (wiring, battery)
- Class D: Metal (rare di equipment, tapi possible magnesium component)
Common Fire Causes di Heavy Equipment:
- Fuel leak: Pada hot exhaust manifold
- Hydraulic leak: High-pressure spray onto hot surface
- Electrical short: Wiring fault, overload
- Overheating: Engine, brake, bearing
- External: Welding spark, brush fire
PASS Technique untuk Menggunakan APAR:
P - PULL the Pin
- Break seal dan pull pin dari handle
- Test discharge briefly untuk ensure working
A - AIM at the Base
- Point nozzle ke base of flame, bukan api di atas
- Stand 2-3 meter dari fire (safe distance)
- Position dengan exit behind you - escape route clear
S - SQUEEZE the Handle
- Firm, steady squeeze untuk discharge
- Control flow - jangan waste agent
S - SWEEP Side to Side
- Move nozzle dari side ke side across base of fire
- Cover entire fire area
- Move forward slowly as fire knocked down
Emergency Fire Procedure:
If Fire Detected While Operating:
- STOP equipment immediately - shut down engine
- EXIT cabin safely - use handrail, don't jump
- Evacuate to safe distance - minimum 10 meter
- Alert others - shout, radio, alarm
- Assess fire size:
- Small (size of trash can): Consider fighting dengan APAR
- Large atau spreading rapidly: EVACUATE, call fire department
- If decide to fight fire:
- Grab APAR dari cabin atau nearby
- Approach dengan wind at your back
- Use PASS technique
- If fire not controlled dalam 10 seconds atau APAR empty - RETREAT
- After fire out:
- Monitor untuk re-ignition - 15 minutes
- Report incident - equipment inspection before use
When NOT to Fight Fire:
- Fire larger than your body size
- Fire blocking your escape route
- Toxic smoke - cab filled with smoke
- Fire near fuel tank - explosion risk
- APAR wrong type untuk fire class
- You tidak trained atau tidak confident
Remember: LIFE > PROPERTY - equipment replaceable, you are not!
APAR Inspection & Maintenance:
- Monthly: Visual check - pressure gauge di green zone, no damage, accessible
- Annual: Professional service - recharge if needed
- After use: Immediate replacement/recharge - even partial discharge
APAR Location di Equipment:
- Mounted di cabin, easily accessible dari operator seat
- Bracket secure - tidak jatuh saat vibration
- Not blocked by tools atau material
