Hazard Identification and Assessment

Date: 2025-10-02

Duration: [DURATION] minutes

Presenter: [PRESENTER NAME]

Location: [LOCATION]

Objective

To equip workers with the knowledge and skills to proactively identify and assess potential safety hazards and risks in the workplace.

Introduction

Hazard identification and assessment are the cornerstones of a safe work environment. By recognizing potential dangers and evaluating their risks, we can prevent accidents and injuries. This toolbox talk will cover the key steps in this process.

Presenter Note: Welcome everyone and briefly explain the purpose of the toolbox talk.

Key Points

• Recognizing Hazards: The first step is to recognize the hazards around you. Only then can you avoid or control them. Discuss hazard recognition tasks with your co-workers, as they may see hazards you overlook. [1]
• Evaluating Risk: After recognizing a hazard, evaluate the risk. Consider the likelihood and severity of potential harm. Combinations of hazards increase risk. [5] [5]
• Control Hazards: Control hazards by creating a safe work environment, using safe work practices, and reporting hazards to a supervisor. [1]
• Inadequate Wiring: Inadequate wiring is a common electrical hazard. This includes exposed electrical parts and wires with bad insulation. [3] [3] [3]
• Wet Conditions: Wet conditions increase the risk of electrical shock. Wet clothing, high humidity, and perspiration also increase your chances of being electrocuted. [4]
• Overhead Powerlines: Overhead powerlines are a significant hazard. Maintain required clearance distances from powerlines. Never store materials and equipment under or near overhead powerlines. [8]

Hazard Identification

• Electrical shock from contact with live wires or equipment: Severe burns, cardiac arrest, death
• Falls from ladders or scaffolding: Broken bones, head trauma, death [7]
• Exposure to harmful chemicals (solvents, paints): Skin irritation, respiratory problems, long-term health issues [4]
• Overloads in electrical systems: Fire, electrical shock [6]
• Contact with overhead powerlines: Electrocution, severe burns, death [9]

Presenter Note: Walk around the work area and actively point out potential hazards. Encourage workers to participate and share their observations.

Control Measures

• De-energize and Lockout/Tagout: Always de-energize electrical circuits before beginning work. Use lockout/tagout procedures to prevent accidental re-energization. [10] [10]
• Use Ground Fault Circuit Interrupters (GFCIs): Use GFCIs in wet locations and construction sites to protect against electrical shock. [8]
• Maintain Safe Distances from Powerlines: Maintain the minimum required clearance distances from overhead powerlines. [8]
• Proper Use of Extension Cords: Inspect extension cords for damage before use. Do not overload circuits. [11]
• Implement Ventilation Systems: Set up ventilation systems, by using floor plans for various sizes and shapes of rooms, to identify the steps to follow for adequate airflow; demonstrating a push/pull system of ventilation; and demonstrating the proper work sequence [2]

Personal Protective Equipment (PPE) Requirements

• Hard Hats: Wear hard hats to protect against falling objects and head injuries. [7]
• Safety Glasses: Use safety glasses or face shields to protect your eyes from flying particles and chemical splashes. [7]
• Rubber Gloves: Linemen should wear special rubber gloves that protect them up to 34,500 volts. [9]
• Appropriate Work Clothing: Wear appropriate work clothing, and ensure you have proper skin coverings. [12]

Real-World Example or Case Study

An electrician was removing a metal fish tape from a hole at the base of a metal light pole. The fish tape became energized, electrocuting the worker. The company failed to de-energize all circuits before beginning work and did not train workers to recognize and avoid unsafe conditions. [10] [10]

Presenter Note: Emphasize the importance of following safety procedures to prevent similar incidents.

Group Discussion

Discuss the following questions:

1. What are some common hazards you've encountered on the job?
2. What steps can we take to improve hazard identification in our workplace?
3. How can we better communicate potential hazards to each other?

Presenter Note: Facilitate an open discussion and encourage everyone to share their thoughts and experiences.

Emergency Procedures

1. In case of electrical shock, immediately shut off the power source if safe to do so.
2. Call emergency services (911) and provide first aid.
3. Report all incidents to your supervisor. [1]

Questions and Answers

• Q: What should I do if I see a damaged power cord?

A: Remove it from service immediately and report it to your supervisor.

• Q: How often should I inspect my PPE?

A: Inspect your PPE before each use to ensure it is in good condition.

• Q: What is a GFCI and how does it work?

A: A GFCI is a ground fault circuit interrupter, a device that detects current leakage from a circuit to ground and shuts the current off [6]

Summary

Recap of main points:

• Recognize potential hazards in your work environment. [1]
• Evaluate the risks associated with those hazards. [5]
• Control hazards through safe work practices and engineering controls. [1]
• Use appropriate PPE to minimize risk. [7]

Action Items

Specific actions participants should take:

1. Actively participate in hazard identification and risk assessment processes.
2. Report any identified hazards to your supervisor immediately.
3. Follow all safe work procedures and use required PPE.

Remember: Safety First: Recognize, Evaluate, Control!

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