Objective


The objective of this toolbox talk is to ensure all personnel understand the hazards associated with concrete walkway demolition and reconstruction, and to implement effective control measures to prevent accidents and injuries.

Introduction


This toolbox talk covers the safety procedures for the demolition and reconstruction of concrete walkways. It emphasizes hazard assessments, fall protection, and pedestrian safety measures to ensure a safe working environment.

Key Points


  • Conduct a Hazard Assessment: Before starting any demolition or reconstruction work, a thorough hazard assessment must be conducted. This assessment should identify potential fall hazards, risks to pedestrians, and any other site-specific dangers.
  • Hazard Recognition: Ensure all workers are trained to recognize new or previously unrecognized fall hazards and report them immediately. [2]
  • Implement Engineering Controls: Implement engineering controls such as guardrails, covers for openings, and warning barriers to protect workers from falls and to safeguard pedestrian traffic. [8]
  • Use Appropriate PPE: Use personal protective equipment (PPE) including hard hats, safety glasses, gloves, and steel-toed boots. When working at heights, fall arrest systems such as harnesses and lanyards are mandatory.
  • Pedestrian Safety Measures: Establish and maintain clear pedestrian walkways, barriers, and signage to ensure the safety of the public and site personnel. Regularly inspect these measures to ensure their effectiveness.
  • Develop a Rescue Plan: Develop a rescue plan that details how to return workers safely to the ground after a fall has been arrested. [5]

Hazard Identification


  • Falls from heights during demolition or reconstruction.: Severe injuries, including fractures, head trauma, or fatalities.

(Risk: High)

  • Falling debris or tools striking workers or pedestrians.: Minor to severe injuries, depending on the size and weight of the object.

(Risk: Medium)

  • Slips, trips, and falls due to uneven surfaces or obstructions.: Sprains, strains, cuts, and bruises.

(Risk: Medium)

  • Unprotected openings or holes in the walkway.: Serious injuries from falls through the openings.

(Risk: High)

  • Contact with utilities (electrical, gas, water) during demolition.: Electrocution, burns, explosions, or flooding.

(Risk: High)

Control Measures


  • Install guardrails and safety nets to prevent falls from elevated walkways.: Ensure guardrails meet height and strength requirements. Safety nets should be installed and inspected regularly. [4]
  • Use fall arrest systems (harnesses, lanyards, and anchor points) when working at heights where guardrails are not feasible.: Inspect fall arrest equipment before each use. Ensure proper fit and anchorage. [3]
  • Implement a safety monitoring system when conventional fall protection is infeasible.: Designate a competent person to monitor workers and warn them of fall hazards. [1]
  • Cover or barricade openings and holes immediately after they are created.: Use covers that can withstand the expected load. Barricades should be highly visible. [8]
  • Establish pedestrian control measures, such as barriers, signage, and designated walkways.: Ensure walkways are clear, level, and well-lit. Regularly inspect and maintain barriers and signage. [6]
  • Conduct regular inspections of equipment, tools, and work areas.: Document inspections and address any deficiencies immediately. [7]

Personal Protective Equipment (PPE) Requirements


  • Hard Hats: Always wear a hard hat to protect against head injuries from falling objects or accidental impacts.
  • Safety Glasses/Face Shields: Use safety glasses or face shields to protect your eyes from dust, debris, and chemical splashes.
  • Gloves: Wear gloves to protect your hands from cuts, abrasions, and chemical exposure.
  • Steel-Toed Boots: Steel-toed boots provide protection against foot injuries from heavy objects or sharp materials.
  • Fall Protection Harness: When working at heights, a full-body harness with a lanyard is required to prevent serious injury from falls. Inspect before each use.

Real-World Example or Case Study


A worker was demolishing a concrete walkway without proper fall protection. He slipped and fell, resulting in a fractured leg and head trauma. This incident highlights the importance of using fall protection equipment and following safety procedures.

Group Discussion


Discuss the following questions:

  1. What are the specific fall hazards on this job site?
  2. What can we do to improve pedestrian safety around the work area?
  3. How do we ensure everyone is properly trained on fall protection equipment?

Emergency Procedures


  1. In case of a fall, immediately activate the emergency response system and provide first aid.
  2. If a utility line is struck, evacuate the area and contact the utility company and emergency services.
  3. For any injury, report the incident to the supervisor and seek medical attention as needed.

Questions and Answers


  • Q: What is a competent person?

A: A competent person is someone who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.

  • Q: When is conventional fall protection not required?

A: Conventional fall protection is not required if it is infeasible or creates a greater hazard. In such cases, a fall protection plan must be developed and followed.

Summary


Recap of main points:

  • Always conduct a thorough hazard assessment before starting work.
  • Use appropriate fall protection measures when working at heights.
  • Implement pedestrian safety measures to protect the public and workers.
  • Report all incidents and injuries immediately.

Action Items


Specific actions participants should take:

  1. Inspect all fall protection equipment before use.
  2. Report any unsafe conditions to the supervisor immediately.
  3. Participate actively in safety briefings and training sessions.

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

# What are elements to consider when writing a fall protection plan? Develop the fall protection plan by involving those individuals with direct experience and whose work will be most impacted. This involvement will allow for input from supervisors and workers whose work involves fall hazards. Involve the joint health and safety committee or representative during the plan development as well. Fall arrest planning includes the steps necessary to prevent the worker from hitting the ground, material, equipment, or lower level of a structure. Determine the fall clearance distance below the work area to make sure that if a worker falls, they do not hit the ground. Workers may swing from side to side when they fall (called the pendulum effect), which also must be taken into consideration. A worker who has fallen and is hanging suspended will need to be rescued by others. A site-specific fall protection plan will incorporate many items, including: - site location (address, description, work area, tasks) - site-specific fall hazards (e.g., maximum height(s), roof slope if applicable, proximity to power lines, ground cover, etc.) - type of fall protection to be used, - protection to be used, including anchor points, and clearance requirements - procedures for fall protection equipment inspection, set-up, use, and removal - any other requirements before beginning work (e.g., presence of first aid or rescue personnel, other safety equipment, barricades, etc.) - rescue procedures - worker sign off ## Who has responsibilities for fall hazards? An employer must: - Develop written fall protection policy and procedures relevant for the workplace. - Identify all areas where there is a potential of injury due to fall. - Prioritize using passive fall arrest systems, such as guardrails, travel restraint, or fall- restricting systems over only relying on personal fall arrest systems. - Develop fall arrest rescue procedures which detail how to return workers safely to

# Subchapter 4. Construction Safety Orders (cont.) ## SUGGESTED SAFETY PROGRAM FOR CONTRACTORS GENERAL (cont.) 5. Display safety posters and warning signs. A sign indicating how many consecutive accident-free days have passed is often worthwhile. 6. Consider the advisability of posting a list of all foremen who have kept their crews accident free for a certain period of time. 7. Consider the advisability of establishing various forms of safety competition, including suitable rewards or recognition to individuals and crews with good records. 8. Require foremen to give individual safety instructions and orders, as needed, to new workers and those found to be working unsafely. 9. Consider the advisability of having the foremen call short "toolbox" or "tail-gate" safety meetings with their crews about once a week on the job, to emphasize some particular safety problem that needs special attention. 10. Keep track of your safety record and keep everyone posted as to progress. A graph or chart, indicating gains - or losses, is good for this purpose. 11. Encourage safety suggestions from all workers and, if the suggestion cannot be followed promptly, explain why to the worker. 12. Consider the advisability of giving each worker a copy of certain important safety rules that they are expected to follow. 13. Arrange for frequent and regular field safety inspections. - Note: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code. - History 1.

# APPENDIX E SAMPLE FALL PROTECTION PLAN NON-MANDATORY GUIDELINES FOR COMPLYING WITH 1926.502(K) (cont.) ## I. Statement of Company Policy (cont.) Each employee must understand their value to the company; the costs of accidents, both monetary, physical, and emotional; the objective of the safety policy and procedures; the safety rules that apply to the safety policy and procedures; and what their individual role is in administering, implementing, monitoring, and compliance of their safety policy and procedures. This allows for a more personal approach to compliance through planning, training, understanding and cooperative effort, rather than by strict enforcement. If for any reason an unsafe act persists, strict enforcement will be implemented. It is the responsibility of (name of competent person) to implement this Fall Protection Plan. (Name of Competent Person) is responsible for continual observational safety checks of their work operations and to enforce the safety policy and procedures. The foreman also is responsible to correct any unsafe acts or conditions immediately. It is the responsibility of the employee to understand and adhere to the procedures of this plan and to follow the instructions of the foreman. It is also the responsibility of the employee to bring to management's attention any unsafe or hazardous conditions or acts that may cause injury to either themselves or any other employees. Any changes to this Fall Protection Plan must be approved by (name of Qualified Person). ## II. Fall Protection Systems to Be Used on This Project Where conventional fall protection is infeasible or creates a greater hazard at the leading edge and during initial connecting activity, we plan to do this work using a safety monitoring system and expose only a minimum number of employees for the time necessary to actually accomplish the job. The maximum number of workers to be monitored by one safety monitor is six (6). We are designating the following trained emp

# Fall Protection - Hierarchy of Control (cont.) ## How can work at heights be eliminated? (cont.) - Moving the item to a level that is not at a height (e.g., control panels) - Using robots, cameras, or drones for cleaning and inspection of equipment - Lowering the object to the ground (e.g., lights that can be lowered by a rope or chain) - Using a device that allows the material to be handled from a safe location (e.g, an extended pole to reach higher areas instead of using ladders when painting or changing light bulbs) ## What engineering controls can be used to reduce work at heights? Engineering controls are methods that are built into the design of a plant, equipment, materials, or other aspects of the physical work environment. For example, guardrails are stationary or fixed (permanent) systems used to protect workers. The system is an engineering control because it does not rely on the worker to be trained to use or wear a fall protection system. Other examples of engineering controls include: - Placing a cover over the hole - Fixed or suspended scaffolding - Mobile elevating work platforms ## What administrative controls can be used? Administrative controls can include workplace policies and rules that instruct workers in fall protection methods. Examples of administrative controls for fall protection include: - Workplace policies and procedures to manage work at heights, including safe work practices, emergency rescue procedures, weather monitoring, etc. - Warning lines - Train and supervise staff to not cross warning lines or enter unsafe zones. - Controlled access zones - Assembling components on the ground to minimize the time spent working at heights (e.g., assembling roof trusses on the ground before hoisting) What are examples of personal protective equipment?

# Fall Protection - Hierarchy of Control (cont.) ## What administrative controls can be used? (cont.) Personal protective equipment includes various methods, including: - Travel Restraint: A travel restraint system restricts workers' movements in the fall hazard area by allowing them to reach the edge, but they cannot fall over the edge. Travel restraint is often used for leading-edge work that has an unprotected floor, roof, deck, or other walking or working surface. - Fall Arrest: The fall arrest system is designed to catch the worker in the event of a fall. If the fall arrest system is not appropriately planned, designed, and installed, the worker may be injured during the fall, including the potential to bottom out. - Safety nets: Safety nets are considered a passive fall protection system that can be installed as either a barrier to prevent a fall or beneath the work to catch a falling worker. Safety nets are designed to decrease the fall distance, absorb the energy of a fall, and reduce the likelihood or seriousness of an injury.

# Fall Protection - Fall Protection Plan (General) (cont.) ## How do I know if my workplace should have a fall protection plan? Each workplace should seek the answers to the following questions: - How is working at heights defined in my jurisdiction? - Are workers working at heights? - Is a hazard assessment required (by law, other authority, or good practice)? - Are you required to have a fall protection plan? ## What are some areas to examine during a hazard assessment for fall protection? Look for all areas or situations where there is a risk of falling before any work begins. - Are there any areas where people may fall during tasks they are expected to do? Examples include: - from a height of 3 m (10 ft) or more - from heights less than 3 m (10 ft) where required (e.g., where there is an increased risk of injury) - into operating machinery - into water or other liquid - into or onto a hazardous substance or object - through an opening in a work surface - Are there controls in place to eliminate or reduce the likelihood of falls? - Are workers trained to recognize new or previously unrecognized fall hazards and report them immediately? - Do workers understand the protective measures taken to reduce falls (e.g., guardrails, safety nets, etc.)? - Is all equipment used by workers stable and in good repair, including guardrails, ladders and scaffolding? - Are floors in work areas in a clean and, so far as possible, dry condition? - Are workers educated and trained to understand how and when to use protective equipment safely? - Are the required personal protective equipment, available, maintained in good condition, and used as instructed?
