Presenter: [PRESENTER NAME]

Location: [LOCATION]

Objective

Provide workers with a practical understanding of how to recognize workplace hazards, assess risk, apply the hierarchy of controls, prevent incidents, and follow OSHA-aligned workplace health and safety procedures before and during the task.

Introduction

Hazard identification is one of the most important parts of preventing injuries and illnesses at work. A job hazard analysis (JHA) helps workers break a task into steps, identify existing and potential hazards, assess the risk, and determine the best ways to eliminate or control those hazards. When workers understand what can go wrong before work begins, they are better prepared to make safe decisions, use the right controls, and stop incidents before they happen. This toolbox talk reinforces the expectation that hazard recognition is a shared responsibility and that safety procedures must be reviewed whenever conditions change. [1] [1] [5]

Presenter Note: Open by asking workers where they see hazards most often on this site and remind them that hazard identification is not a paperwork exercise—it is a daily work habit.

Key Points

• 1. Break the job into steps before work starts: A good hazard review begins by separating the task into clear, manageable steps. Observing the work and listing each step helps the crew identify where hazards are introduced, where exposure occurs, and where controls are needed. This approach is especially useful for non-routine work, complex tasks, and jobs with a history of incidents or near misses. [1] [1] [16]
  • Observe the task being performed whenever possible.
  • Record the steps in the order they occur.
  • Review the steps with the workers who actually perform the job.
  • Update the analysis if the task, tools, or site conditions change.
• 2. Involve the people who do the work: Employees who perform the task every day often know the practical hazards, shortcuts, and site conditions better than anyone else. Their input improves the quality of the hazard assessment and helps identify realistic controls that can actually be followed in the field. Worker participation also improves ownership of the safety process and increases compliance with safe work procedures. [1] [6]
  • Ask workers what can go wrong at each step.
  • Include supervisors, foremen, and other knowledgeable personnel in the discussion.
  • Treat worker observations seriously and follow up on concerns.
  • Use the crew briefing to confirm everyone understands the hazards and controls.
• 3. Recognize both obvious and hidden hazards: Some hazards are easy to see, such as unguarded machinery, falls, struck-by hazards, or exposed electrical parts. Others are less obvious, including ergonomic strain, repetitive motion, poor lighting, wet surfaces, unstable materials, or changing weather conditions. Workers should look at the task, the tools, the environment, and the people involved to identify all credible sources of harm. [1] [2] [14]
  • Look for physical hazards such as moving parts, edges, heights, and pinch points.
  • Consider environmental hazards such as weather, lighting, noise, dust, and slippery surfaces.
  • Identify human factors such as rushing, fatigue, inexperience, or poor communication.
  • Check whether nearby work activities create new exposure.
• 4. Assess risk by considering severity and likelihood: Once hazards are identified, evaluate how serious the injury could be and how likely it is to occur. A useful risk assessment considers who or what is exposed, what could go wrong, what conditions could trigger the event, and what factors could make the incident worse. High-risk work should be stopped until effective controls are in place. [1] [1] [15]
  • Ask who is exposed and how exposure occurs.
  • Consider the worst credible outcome, not just the most likely one.
  • Account for contributing factors such as weather, congestion, or equipment condition.
  • Reassess risk when the work changes or new hazards appear.
• 5. Use the hierarchy of controls to reduce exposure: The hierarchy of controls is the preferred method for managing hazards. Start by eliminating the hazard if possible, then substitute a safer option, apply engineering controls, use administrative controls, and rely on PPE only as the last line of defense. The goal is to reduce exposure at the source rather than depending only on worker behavior. [2] [2] [3]
  • Eliminate the hazard whenever the task can be redesigned or removed.
  • Substitute less hazardous materials, tools, or methods when elimination is not practical.
  • Use engineering controls such as guards, barriers, or isolation.
  • Apply administrative controls such as procedures, training, signage, and job briefings.
  • Use PPE to supplement other controls, not replace them.

Hazard Identification

Common workplace hazards can appear in almost any task. The most effective way to prevent injuries is to identify hazards early, understand how they can harm workers, and apply controls before work begins. The hazards below are representative of the types of conditions workers should look for during a JHA or pre-task plan.

• Unguarded machinery, moving parts, and pinch points: Workers can become caught, crushed, pinched, or entangled, leading to fractures, amputations, internal injuries, suffocation, or death. [4] [4]

(Risk: High)

• Struck-by hazards from vehicles, falling objects, swinging loads, or flying debris: Workers may suffer head trauma, fractures, crushing injuries, eye injuries, or fatal impact injuries. [7] [7]

(Risk: High)

• Slips, trips, and falls caused by wet surfaces, clutter, debris, cords, holes, or poor lighting: Workers may suffer sprains, fractures, head injuries, lost-time injuries, or fatal falls depending on the surface and height involved. [10] [10]

(Risk: Medium)

• Falls from heights, openings, ladders, scaffolds, roofs, or elevated work platforms: A fall can cause severe trauma, paralysis, permanent disability, or death, especially when working near edges, openings, or dangerous equipment. [12] [12]

(Risk: High)

• Electrical exposure, including energized equipment and arc flash potential: Workers may experience shock, burns, arc flash injuries, fire, or electrocution. [8] [8]

(Risk: High)

• Trenching and excavation cave-ins or unstable soil conditions: A collapse can bury workers, causing suffocation, crushing injuries, or fatal entrapment. [4] [4]

(Risk: High)

Presenter Note: Use the hazard list to prompt workers to name examples from their own tasks. Ask them to identify both the hazard and the likely consequence before discussing controls.

Control Measures

Use the hierarchy of controls in order of preference. First ask whether the hazard can be eliminated by changing the task or work location. If not, look for substitution or engineering controls that isolate workers from the hazard. Then apply administrative controls such as procedures, training, signage, inspections, and job briefings. PPE should be used only after higher-level controls have been considered and implemented where practical.

• Eliminate the hazard by redesigning the task or changing the work method: Whenever possible, remove the hazard entirely. For example, perform work at ground level instead of at height, or redesign the process so workers do not need to enter the hazard zone. [2] [2]
• Substitute safer materials, tools, or processes: Replace hazardous substances or methods with less hazardous alternatives, such as using water-based products instead of solvent-based products when the task allows. [2] [2]
• Install engineering controls to isolate workers from the hazard: Use guards, barriers, guardrails, enclosures, machine guarding, or other physical controls to prevent contact with the hazard and reduce exposure. [2] [4]
• Apply administrative controls and safe work procedures: Use JHAs, pre-task planning, written procedures, job briefings, signage, access control, and training to ensure the work is performed consistently and safely. Rebrief the crew whenever conditions change. [1] [5]
• Inspect tools, equipment, and the work area before use: Check for damaged guards, unstable ground, poor lighting, unsecured materials, wet surfaces, exposed cords, and other changing conditions. Correct hazards immediately when it is safe to do so, or stop work and escalate if the hazard cannot be controlled. [2] [2]
• Use PPE as the last line of defense and ensure it is matched to the hazard: Select PPE based on the hazard assessment, verify proper fit, and train workers on correct use, limitations, inspection, and replacement. PPE should supplement, not replace, higher-level controls. [3] [15]

Safe Work Procedures

1. Review the task, site conditions, permits, and applicable JHA or pre-task plan before starting work. Confirm that the crew understands the hazards, controls, and stop-work expectations. [5] [1]
2. Observe the work area for changing conditions such as weather, congestion, poor lighting, unstable surfaces, moving equipment, or nearby operations that could create new hazards. [1] [2]
3. Perform the task only within the controls that have been established. If the hazard changes or the control is no longer effective, stop work and reassess before continuing. [15] [5]
4. Report hazards, near misses, injuries, and control failures immediately so the team can correct the issue and prevent recurrence. [2] [3]

Presenter Note: Walk the crew through the sequence: review, observe, control, execute, and report. Emphasize that a JHA is not complete until the controls are actually used in the field.

Personal Protective Equipment (PPE) Requirements

• Hard Hat: Wear a hard hat whenever there is a risk of head injury from falling objects, overhead work, moving equipment, or struck-by hazards. Inspect the shell and suspension before use, keep the hat properly adjusted, and replace it if it is cracked, damaged, or no longer fits correctly. [13] [7]
  • Use the correct class and type for the task and site conditions.
  • Do not modify the shell or suspension.
  • Replace damaged hard hats immediately.
• Safety Glasses or Goggles: Use eye protection whenever there is a risk of flying particles, dust, splashes, or debris. Safety glasses are appropriate for general impact protection, while goggles or face shields may be needed for higher exposure or splash hazards. Eye protection must fit properly and remain in place during the task. [11] [13]
  • Choose the lens and frame style that matches the hazard.
  • Use side protection where impact exposure exists.
  • Replace scratched or damaged lenses that reduce visibility.
• Gloves: Select gloves based on the hazard, such as cut-resistant gloves for sharp materials, general-purpose gloves for handling stock, chemical-resistant gloves for chemical exposure, or insulated gloves for electrical work when appropriate. Gloves must fit properly and should not create a new entanglement hazard around rotating equipment. [13] [4]
  • Match glove material to the hazard.
  • Keep gloves away from moving parts where entanglement is possible.
  • Replace torn, worn, or contaminated gloves.
• Safety-Toe Footwear: Wear safety-toe or steel-toe footwear with slip-resistant soles when there is a risk of falling objects, rolling stock, sharp debris, or slippery walking surfaces. Footwear should be appropriate for the terrain and maintained in good condition to preserve traction and protection. [9] [13]
  • Use slip-resistant soles for wet, oily, or uneven surfaces.
  • Keep footwear clean and dry when possible.
  • Replace worn soles that reduce traction.
• Hearing Protection: Use ear plugs, ear muffs, or canal caps when noise exposure is high enough to damage hearing. Hearing protection must be worn correctly and consistently in noisy areas, and workers should understand that hearing loss can occur gradually over time. [13] [11]
  • Select the correct noise reduction rating for the task.
  • Wear hearing protection before entering the noisy area.
  • Inspect reusable hearing protection and keep it clean.

PPE is important, but it is the last line of defense. Workers must understand the purpose of each item, verify that it fits properly, inspect it before use, and replace damaged or ineffective PPE immediately. PPE works best when combined with elimination, engineering, and administrative controls. [3] [13]

Real-World Example or Case Study

A crew was assigned to move materials through a congested work area while another team was operating equipment nearby. During the pre-task review, workers identified a struck-by hazard from moving equipment and a caught-between hazard near a fixed structure. The supervisor changed the sequence of work, established a barricaded travel path, required eye contact with operators before entry into the work zone, and kept workers out of the swing radius and pinch-point areas. The task was completed without incident. The lesson was simple: when workers identify hazards early and adjust the plan before work starts, they prevent injuries that would otherwise happen in seconds. [7] [4] [5]

Presenter Note: Use this example to show how a small change in work sequencing and access control can eliminate a serious exposure.

Group Discussion

Discuss the following questions:

1. What hazards are most likely to be missed when we rush through a task review?
2. Which control on our site is strongest right now: elimination, engineering, administrative controls, or PPE? Why?
3. What should you do if the work area changes after the JHA has already been reviewed?

Presenter Note: Encourage workers to answer from their own experience. Ask follow-up questions about recent near misses, changing site conditions, or controls that did not work as expected.

Emergency Procedures

1. Stop work immediately if a high-risk hazard is discovered or if a control fails. Make the area safe if it can be done without exposing anyone to additional danger. [15]
2. Notify the supervisor or competent person, isolate the area, and prevent others from entering until the hazard is corrected or the task is re-planned. [2] [1]
3. If an injury occurs, summon emergency medical assistance, provide first aid within your training, and preserve the scene for investigation when it is safe to do so. [2]

Questions and Answers

Questions are encouraged. Use this time to raise concerns about site conditions, task changes, equipment issues, or any hazard that is not fully controlled.

• Q: What is the purpose of a job hazard analysis?

A: A JHA identifies the steps of a task, the hazards associated with each step, the risk involved, and the controls needed to eliminate or reduce exposure. [1]

• Q: When should a JHA be reviewed again?

A: The JHA should be reviewed before the job starts and again whenever conditions change, new hazards appear, or additional tasks are added. [1] [5]

• Q: Why is PPE not the first choice for hazard control?

A: PPE is the least effective level of control because it does not remove the hazard; it only reduces exposure if it is selected correctly, worn properly, and maintained. [3]

• Q: What should workers do if they identify a hazard during the job?

A: They should stop and report the hazard if it cannot be corrected safely, then work with supervision to implement the appropriate control before continuing. [2] [15]

Summary

Recap of main points:

• Hazard identification starts with breaking the job into steps and involving the workers who know the task best. [1]
• Every task should be evaluated for obvious and hidden hazards, including struck-by, caught-in/between, fall, slip/trip, electrical, and excavation risks. [2] [14]
• Use the hierarchy of controls first, and rely on PPE only as the last line of defense. [2] [3]
• Review the JHA, communicate changes, and stop work when conditions change or a high-risk hazard is discovered. [1] [15]

Action Items

Specific actions participants should take:

1. Before starting work, review the task steps, hazards, controls, and required PPE with the crew. [1]
2. Report changing conditions, near misses, damaged equipment, and uncontrolled hazards immediately. [2]
3. Use the correct control for the hazard and do not rely on PPE alone when a stronger control is available. [3]
4. Stop work and rebrief the crew if the job, environment, or equipment changes. [1]
5. Participate actively in hazard reporting and help improve the safety process through feedback. [5]

Remember: See the hazard, assess the risk, control the exposure, and stop work before the incident happens.

Report all hazards, near-misses, and incidents to your supervisor immediately.
