Objective

The objective of this toolbox talk is to ensure all personnel understand the hazards associated with confined spaces and the necessary safety procedures to mitigate those risks.

Introduction

Confined space entry can be hazardous. This toolbox talk will cover the procedures for safely working in confined spaces, including hazard assessment, ventilation, and emergency rescue.

Presenter Note: Briefly introduce the topic and its importance. Highlight any recent incidents or near misses related to confined space entry.

Key Points

• Training: All personnel involved in confined space entry must be properly trained in hazard recognition, entry procedures, and rescue operations. [2]
• Entry Permit: A written permit is required before entering a confined space. The permit must identify hazards, control measures, and authorized entrants. [1]
• Atmospheric Monitoring: The atmosphere inside the confined space must be tested before entry and continuously monitored during work. [1] [1]
• Ventilation: Ventilation is crucial to maintain a safe atmosphere. Use forced air ventilation to remove hazardous gases and ensure adequate oxygen levels. [1]
• Attendant: An attendant must be stationed outside the confined space to monitor entrants and provide assistance if needed. [1]
• Rescue Procedures: Develop and implement procedures for summoning rescue and emergency services, for rescuing entrants from permit spaces, for providing necessary emergency services to rescued employees, and for preventing unauthorized personnel from attempting a rescue [3]

Hazard Identification

Confined spaces can present a variety of hazards that can be life-threatening. It is crucial to identify and evaluate these hazards before entry.

• Oxygen deficiency: Asphyxiation, loss of consciousness, death
• Presence of toxic gases (e.g., hydrogen sulfide): Poisoning, respiratory failure, death [4]
• Presence of explosive/flammable gases: Fire, explosion, severe burns, death [4]
• Engulfment hazards (e.g., liquids, solids): Suffocation, crushing injuries, death [4]
• Mechanical hazards (e.g., moving parts): Crushing, amputation, entanglement

Presenter Note: Emphasize the importance of identifying all potential hazards before entry. Use real-world examples from your workplace.

Control Measures

• Permit-Required Confined Space Program: Implement a comprehensive permit-required confined space program that includes measures to prevent unauthorized entry, identify and evaluate hazards, and develop safe entry procedures. [3] [3] [3]
• Atmospheric Testing: Test the atmosphere before entry for oxygen levels, flammable gases, and toxic substances. Continuous monitoring should be conducted during the entry. [1] [1]
• Ventilation: Use mechanical ventilation to ensure a safe atmosphere. Ventilation should begin before entry and continue throughout the work. [1] [1]
• Lockout/Tagout: Implement lockout/tagout procedures to control energy sources and prevent accidental activation of equipment within the confined space.
• Attendant: An attendant must be stationed outside the confined space to monitor entrants and summon help if needed. [1]
• Entry Permit: A Confined Space Entry Permit must be completed before approval can be given to enter a permit-required confined space. This permit verifies completion of items listed below. This permit shall be kept at the job site for the duration of the job. [1]

Personal Protective Equipment (PPE) Requirements

• Supplied Air Respirator (SAR): A supplied air respirator (SAR) provides a continuous supply of breathable air from an external source. Ensure the air supply isGrade D breathing air and the respirator fits properly.
• Full Body Harness with Lifeline: A full body harness with a lifeline allows for non-entry rescue. Ensure the harness fits snugly and the lifeline is properly attached to a retrieval system. [1]
• Chemical Resistant Gloves: Wear appropriate gloves to protect against chemical or physical hazards present in the confined space.
• Eye Protection: Use appropriate eye protection, such as goggles or a face shield, to protect against splashes, fumes, or dust.

Real-World Example or Case Study

A worker entered a confined space without proper atmospheric testing. The space contained high levels of hydrogen sulfide, leading to the worker's incapacitation. The attendant, who was properly trained, immediately called emergency services and initiated a non-entry rescue, saving the worker's life. This highlights the importance of pre-entry testing and having a trained attendant.

Presenter Note: Share any relevant case studies or near-miss incidents from your workplace to reinforce the importance of following safety procedures.

Group Discussion

Discuss the following questions:

1. What types of confined spaces do we have in our workplace?
2. What are the potential hazards associated with these spaces?
3. Are our current confined space entry procedures adequate? How can we improve them?

Presenter Note: Encourage open discussion and participation from all attendees. Document any suggestions for improvement.

Emergency Procedures

1. Immediately call for emergency services (e.g., fire department) for rescue. [1]
2. Do not enter the confined space without proper training and equipment.
3. Attempt non-entry rescue using a lifeline if possible. [1]

Questions and Answers

Here are some common questions related to confined space entry:

• Q: What is a confined space?

A: Confined spaces are defined as spaces that are large enough for an employee to enter and perform work, have limited or restricted means for entry or exit, and are not designed for continuous employee occupancy.

• Q: What are some examples of confined spaces?

A: Examples include tanks, silos, storage bins, manholes, and pipelines.

• Q: What is the role of an attendant?

A: An attendant is stationed outside the confined space to monitor entrants, communicate with them, and summon rescue services if needed. [2]

• Q: What should you do if an alarm sounds inside the confined space?

A: If an alarm sounds or a hazardous condition is detected, all entrants must immediately exit the confined space.

Summary

Recap of main points:

• Confined spaces present significant hazards that require strict adherence to safety procedures.
• Proper hazard assessment, atmospheric testing, ventilation, and the use of appropriate PPE are essential for safe entry.
• A trained attendant and well-defined rescue procedures are critical for responding to emergencies.
• Always follow the permit-required confined space program and never enter a space without proper authorization. [1]

Action Items

Specific actions participants should take:

1. Review the company's confined space entry program.
2. Participate in confined space entry training. [2]
3. Ensure you understand the proper use of PPE for confined space entry.

Remember: Confined Space: Know the Risks, Follow the Procedures, Stay Safe.

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