Chapter 2.1

Identifying Hazards

See the hazard before it becomes an accident.

A construction site can look normal while hiding serious hazards. Learning to recognize what could cause harm is the first step toward preventing accidents.

What Is a Hazard?

A hazard is anything that has the potential to cause harm.

On a construction site, hazards can come from:

  • People and unsafe actions
  • Tools and machinery
  • Materials
  • Electricity
  • The work environment

Know What to Look For

Some hazards are obvious. Others are easy to miss. Look for:

Falls : Open edges, floor openings and unsafe access

Falling Objects : Loose materials, tools and suspended loads

Moving Equipment : Vehicles, machinery and blind spots

Electrical Hazards : Damaged cables, exposed wires and unsafe connections

Fire & Chemical Hazards : Flammable materials, hot work, fumes and chemicals

Environmental Hazards : Dust, noise, heat and poor lighting

Hazard vs Risk

A hazard is something that can cause harm.

Risk is the likelihood of harm occurring and how serious the consequences could be.

HAZARD → EXPOSURE → RISK → CONSEQUENCE

Hazards Can Change

Construction sites are constantly changing.

  • A clear walkway can become blocked.
  • A new machine can enter the work area.
  • Materials can be lifted overhead.
  • A new activity can create a new hazard.

A changing site can create changing hazards.

When You Spot a Hazard

Don’t ignore a hazard just because nothing has happened yet.

SEE IT

Recognize what could cause harm.

UNDERSTAND IT

Think about what could happen and who could be affected.

REPORT IT

Tell the responsible person.

CONTROL IT

Make sure appropriate action is taken before someone is harmed.

Quick Hazard Check

Ask yourself:

☐ What can cause harm?
☐ Who could be affected?
☐ How could it happen?
☐ What should be done?

Familiar does not mean safe.

A quick scan today prevents a serious injury tomorrow.

SCAN. IDENTIFY. THEN PROTECT.
