Maintaining Safe Distances
The Problem
Maintaining safe distances is one of the most effective ways to prevent incidents, injuries, and fatalities on the worksite. When workers get too close to moving machinery, hazardous operations, or high-risk zones, the consequences can be severe. Today, we’ll address the importance of safe distances, highlight common hazards, and discuss practical solutions to ensure everyone stays safe.
Identify the Hazards
- Machinery operating too close to workers or structures
- Inadequate or poorly maintained barriers
- Poor communication between operators, spotters, and workers on the ground
- Unauthorised personnel entering exclusion zones
- Multiple activities occurring in close proximity
Safety Practices and Preventative Measures
Establish Clear Work Zones
- Clearly define zones using barriers, signage, and lighting.
- Allocate zones for:
- Machinery operation
- Material handling and storage
- Pedestrian-only areas
- Vehicle access routes
- Establish and maintain exclusion zones around high-risk areas.
Barrier Requirements
- Use solid barriers (e.g., concrete, fencing) for high-risk operations.
- Use soft barriers (e.g., cones, bunting, warning tape) for lower-risk activities.
- Ensure all barriers are:
- Highly visible and marked with appropriate signage
- Regularly inspected and maintained
- Fitted with reflective materials and lighting for night or low-light conditions
Effective Communication Protocols
- Implement clear communication methods:
- Standardized hand signals
- Two-way radios where verbal communication is not effective
- Ensure regular communication between spotters and operators
- Train workers in consistent communication protocols
Spotter Positioning
- Assign spotters in:
- Machinery blind spots
- Busy pedestrian areas
- Areas requiring complex movements
- Spotters must:
- Wear high-visibility clothing
- Maintain direct line of sight
- Use agreed-upon signals or communication devices
Emergency Procedures
- Clearly define emergency assembly points and escape routes
- Maintain minimum safe distances during emergencies, such as:
- Machinery malfunction
- Contact with live services
- Fire or hazardous substance release
- Review and practise emergency procedures regularly
Traffic Management Measures
- Implement a traffic management plan to:
- Separate vehicles and pedestrians
- Define vehicle accessways and work zones
- Enforce speed limits and signage requirements
- Maintain effective control measures where multiple machines operate nearby
Real-Life Case or Scenario
On a recent construction site, a worker was seriously injured after entering an active machinery zone without permission. The machine operator did not see the worker due to blind spots, and there were no barriers in place to restrict access. This incident could have been avoided with clear signage, effective barriers, and better communication protocols.
Employee Responsibilities
- Respect all exclusion zones and designated work areas.
- Communicate clearly with machinery operators and spotters.
- Use designated walkways and crossing points.
- Report missing signage, damaged barriers, or unsafe conditions immediately.
Employer Responsibilities
- Clearly define and mark all work zones and exclusion areas.
- Provide and maintain visible signage and appropriate barriers.
- Train workers on hazard identification, communication protocols, and traffic management.
- Regularly inspect and maintain all safety systems.
Discussion & Questions
- “Where on our site have you seen safe distances being ignored?”
- “How do we currently communicate with machine operators—what works well, and what doesn’t?”
- “What could we improve to better protect workers near machinery or moving vehicles?”
Commitment/Action Plan
Starting today, let’s all commit to recognizing and respecting designated work zones. Before starting work, identify any ‘No-Go Zones’, confirm communication lines with operators, and report any concerns immediately. It’s everyone’s job to maintain safe distances.
Wrap-Up
Safe distances save lives. With proper planning, communication, and hazard awareness, we can protect each other and ensure everyone returns home safely. Thank you for taking safety seriously and putting these practices into action.
Standards Overview
Canadian occupational health and safety regulations require that effective separation is maintained between workers and machinery or vehicles, especially in high-risk areas such as near excavations, cranes, or live services. Key regulations and guidance include:
- Canada Labour Code and provincial occupational health and safety acts
- CCOHS guidelines on traffic management and mobile equipment
- CSA standards and relevant codes of practice for temporary works and safe distances
