This poster is a full summary of how we identify and rank workplace incidents in HSE. It's built on two ideas

 This poster is a full summary of how we identify and rank workplace incidents in HSE. It's built on two ideas:

"Different situations, Same goal — Safer workplaces" and "Report, Learn, Prevent."

It has 2 parts.

1. TYPES OF INCIDENTS

Definition used here: An incident is any unplanned event that could have, did, or may lead to harm, loss or disruption.

That means even if nothing happened, if it could have, we still count it. The 10 types are:

- ACCIDENT: The harm actually happened. Injury, illness, property damage or environmental harm. 

Example: Fall from height, vehicle collision.

- NEAR MISS: It almost happened. No injury or damage this time, but had the potential to. This is your free lesson.

Example: Dropped tool that missed a worker.

- HAZARD: The source of potential harm itself. Not yet an event, just something that could cause one.

Example: Exposed electrical wiring, unguarded machinery.

- UNSAFE CONDITION: The physical state of the workplace that can lead to an incident. This is the environment.

Example: Poor lighting, blocked emergency exit.

- UNSAFE ACT: The human side. Behaviour that increases risk.

Example: Not using PPE, ignoring safety procedure.

The difference is important: HAZARD is the potential, UNSAFE CONDITION is the unsafe workplace, UNSAFE ACT is the unsafe person.

- PROPERTY DAMAGE: Damage to equipment, vehicles, buildings.

Example: Equipment breakdown, vehicle damage.

- ENVIRONMENTAL INCIDENT: Harm to the environment, or potential harm.

Example: Oil spill, chemical leak, air or water pollution.

- OCCUPATIONAL ILLNESS: Health problem caused or made worse by work over time, not instantly.

Example: Respiratory disease, hearing loss, skin irritation.

- SECURITY INCIDENT: Threat to people, assets, or information.

Example: Theft, violence, unauthorised access.

- PROCESS SAFETY INCIDENT: Loss of control of a process. The big ones in oil and gas, manufacturing.

Example: Hydrocarbon release, fire or explosion in process unit.

2. INCIDENT CLASSIFICATION

This is how we rank the same incident by severity, impact, and what response it needs:

| Classification | What it means | Example | Impact | Response 

| 1. FIRST AID (Injury only) | Minor injury, first aid only | Small cut, minor burn | No lost time, minimal disruption | First aid, report, monitor 

| 2. MEDICAL TREATMENT (Lost Time) | Needs a doctor, person misses work | Fracture, serious cut, back injury | Lost time, reduced productivity | Medical treatment, record, investigation 

| 3. SERIOUS INCIDENT | Life-threatening, major damage, significant environmental impact | Multiple injuries, major fire, chemical release, collapse | Severe injury or fatality risk, major business interruption | Emergency response, full investigation, regulatory notification 

| 4. MAJOR INCIDENT | Catastrophic | Fatality, plant explosion, large oil spill, total loss of facility | Multiple fatalities, long-term environmental damage, major financial loss | Emergency response, external authorities, comprehensive investigation, corrective action 

| 5. ZERO HARM EVENT | Nothing happened, but it was high-potential and we caught it | Potential fall caught, gas leak detected and stopped, unsafe act observed | No harm, but it prevents the next one | Immediate control, closeout, share lessons learned 

This last one is why reporting culture matters. Zero Harm Events and Near Misses are where you prevent the Serious and Major ones.

KEY TAKEAWAYS at the bottom

Report all incidents (major or minor) — If you only report big ones, you lose your early warnings.

Investigate the root cause, not just the symptoms — Don't stop at "worker didn't wear PPE," ask why.

Fix the hazards and prevent recurrence — Close the loop.

Everyone has a role — Safety is not just HSE department's job.

And the footer sums it up: Less Incidents = Safer People = A Stronger Tomorrow.

This is a perfect poster for a toolbox talk or induction. You can use it to ask your team: "In the last week, what did we have — a hazard, an unsafe act, or a near miss — and did we report it as a Zero Harm Event?" ⛑️🚨🚥⚠️🗼🦺🚦🌡️🏗️🚧
