Objective

To ensure all workers understand the hazards associated with formwork and the necessary safety precautions to prevent injuries during commercial concrete operations.

Introduction

Formwork is a temporary structure used to contain and support concrete during pouring and curing. Because formwork is temporary, it is critical to build it correctly to avoid collapses and other serious incidents. This toolbox talk will cover key safety aspects of formwork, including hazard identification, fall protection, and safe work practices.

Key Points

• Proper Design and Planning: Formwork must be designed to withstand all anticipated vertical and lateral loads. Drawings and plans, including all revisions, for the jack layout, formwork (including shoring equipment), working decks, and scaffolds, shall be available at the jobsite. [5] [5]
• Competent Person Inspections: A competent person must inspect all shoring equipment before erection to ensure it meets formwork drawing requirements. Inspections should also occur immediately prior to, during, and immediately after concrete placement. Any damaged or weakened shoring must be reinforced immediately. [2] [4] [4]
• Fall Protection: When placing or tying reinforcing steel in walls, piers, or columns more than 6 feet above an adjacent surface, use a personal fall protection system. Ensure guardrails are installed on work platforms and scaffolds. [6]
• Safe Removal of Formwork: Forms and shores shall not be removed until the concrete has gained sufficient strength to support its weight and any superimposed loads. This determination should be based on stipulated conditions in the plans and specifications or proper testing with an appropriate ASTM standard test method. [3] [2]
• Bracing and Stability: Single-post shores must be horizontally braced in both longitudinal and transverse directions with diagonal bracing installed as the shores are erected. The tops of single-post shores should be restricted from movement using retainers or equivalent means. [1] [1]

Hazard Identification

• Formwork Collapse: Serious injuries or fatalities due to being crushed or struck by falling formwork and concrete.
• Falls from Elevation: Injuries from falling off formwork during erection, modification, or dismantling.
• struck by falling objects: Head injuries, lacerations, or fractures from falling tools, materials, or concrete.
• Equipment Malfunction: Injuries due to failure of jacks, lifting devices, or other equipment used in formwork operations.

Control Measures

• Implement a comprehensive fall protection program.: Ensure all workers exposed to fall hazards above 6 feet are using appropriate fall protection systems, such as personal fall arrest systems (harnesses, lanyards, and anchor points) or guardrails.
• Conduct thorough inspections of all formwork components.: Before each use, inspect forms, shores, braces, and hardware for damage, wear, or defects. Remove any compromised components from service.
• Ensure proper shoring and bracing.: Follow the engineered formwork plan for shoring and bracing requirements. Install bracing as the formwork is erected to maintain stability.
• Control access to formwork areas.: Limit access to formwork erection and dismantling areas to essential personnel. Use barricades and signage to prevent unauthorized entry.
• Provide comprehensive training.: Train all workers involved in formwork operations on hazard recognition, safe work procedures, fall protection requirements, and emergency procedures.

Personal Protective Equipment (PPE) Requirements

• Hard Hats: Always wear a hard hat to protect against head injuries from falling objects or bumping into structures. Ensure the hard hat fits properly and is in good condition.
• Safety Glasses: Use safety glasses with side shields to protect your eyes from dust, debris, and concrete splashes.
• Gloves: Wear heavy-duty gloves to protect your hands from cuts, abrasions, and skin irritation when handling formwork materials and concrete.
• Steel-Toed Boots: Wear steel-toed boots to protect your feet from crushing injuries and punctures.

Real-World Example or Case Study

In 2023, a formwork collapse occurred on a high-rise construction project in Atlanta, Georgia, resulting in multiple injuries. The investigation revealed that the formwork was not properly designed for the load, and inspections were inadequate. This incident highlights the critical importance of proper design, inspection, and adherence to safety protocols.

Emergency Procedures

1. In case of a formwork collapse, immediately evacuate the area and account for all personnel.
2. If someone is injured, provide first aid and call for emergency medical services.
3. Report all incidents and near misses to the supervisor and safety department for investigation and corrective action.

Questions and Answers

Now, let's open the floor for questions. This is an opportunity to clarify any doubts and ensure everyone fully understands the safety requirements for working with formwork.

• Q: What should I do if I see a potential problem with the formwork?

A: Immediately report it to your supervisor or a qualified person. Do not attempt to fix it yourself unless you are trained and authorized to do so.

• Q: How often should formwork be inspected?

A: Formwork should be inspected before erection, during erection, and immediately before, during, and after concrete placement.

Summary

Recap of main points:

• Formwork safety is crucial for preventing serious injuries and fatalities on construction sites.
• Proper design, inspection, and maintenance of formwork are essential.
• Always use appropriate fall protection when working at heights.
• Report any potential hazards or concerns immediately.

Action Items

Specific actions participants should take:

1. Actively participate in pre-task planning and hazard assessments.
2. Inspect your PPE before each shift to ensure it is in good working condition.
3. Follow all safe work procedures and report any unsafe conditions immediately.

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