Near Miss vs First-Aid Case IN

Near miss

  • No injury occurred
  • Had potential harm

First-aid case

  • Minor injury treated

Common Traps

Unsafe act ≠ unsafe condition

  • Act is behavior ≠ Condition is physical

DO 198-18 ≠ DO 252-25

  • 198-18 is original 2018 ≠ 252-25 is revised 2025

BOSH ≠ COSH training

  • BOSH is general industry ≠ COSH is construction only

Near miss ≠ first-aid case

  • Near miss has no injury ≠ First-aid case has injury

Elimination ≠ substitution

  • Elimination removes hazard ≠ Substitution replaces hazard

AEDR ≠ AMR

  • AEDR is exposure data ≠ AMR is medical report

Lockout ≠ tagout

  • Lockout applies physical lock ≠ Tagout applies warning label

Last Minute

  • 1. SO2 needs 40-hour BOSH course
  • 2. RA 11058 is the OSH Law
  • 3. DO 252-25 is current revised IRR
  • 4. HIRAC: identify, assess, control hazards
  • 5. Controls: eliminate before using PPE
  • 6. WAIR due monthly by the 30th
  • 7. AEDR due every January 30
  • 8. AMR due every March 31
  • 9. Max fine: 100,000 pesos per day
