DIFFERENCE BETWEEN NEAR-MISS, INCIDENT AND ACCIDENT

confused — but they are not the same.

Near-Miss (Close Call)

Definition:
An unplanned event that did not result in injury, illness, or damage, but had the potential to do so.

Key Point:
No harm occurred — but it could have.

Examples:

• A rock falls in an underground mine but misses workers.
• A load slips from a crane but lands safely without injury.
• A worker almost slips on an oil spill but regains balance.
• A vehicle brakes just in time to avoid collision.

Why it is important:
Near-misses are warning signs. If not corrected, the next event may be an accident.

Legal Perspective:
While near-misses are not always legally reportable, they must be recorded internally as part of effective risk management under:

• The Occupational Health and Safety Act (OHS Act)
• The Health and Safety Act (MHSA)

Incident

Definition:
An unplanned event that results in minor injury, illness, damage, or loss, or could have resulted in serious harm.

Key Point:
Some level of loss or damage occurred (not necessarily serious).

Examples:

• Minor injury requiring first aid.
• Small equipment damage.
• Spillage of hazardous material.
• Minor vehicle collision on site.

In mining, the term incident is often used broadly and may include near-misses depending on company policy.

Accident

Definition:
An unplanned event that results in serious injury, illness, fatality, or significant damage.

Key Point:
Harm has occurred.

Examples:

• Fall of ground causing injury.
• Worker electrocuted.
• Amputation from machinery.
• Fatal vehicle collision.
• Structural collapse.

Legal Requirement (South Africa):
Serious accidents must be reported to:

• Department of Employment and Labour (OHS Act)
• Department of Mineral Resources and Energy (MHSA – Section 11 & 23 reporting)

Simple Comparison Table

Practical Safety Perspective

In modern safety management systems (ISO 45001, MHSA risk management):

• Near-miss reporting is critical
• 1 serious accident is usually preceded by:
  • Many minor incidents
  • Hundreds of near-misses
    (Heinrich’s Safety Triangle Principle)

If you control near-misses → you prevent accidents.

In Mining Context (Example)

Scenario: Underground coal mine

• Gas detector alarms but no ignition → Near-miss
• Minor burn from a small methane flash → Incident
• Explosion causing injuries → Accident
