Trenching safety is crucial for our industry. Recent developments and ongoing challenges highlight the need for vigilance and best practices. Here’s a concise overview of the latest news and essential tips for maintaining top-notch trenching safety programs.
Recent Developments
In 2022, trenching safety awareness and enforcement saw significant changes due to a spike in fatalities. OSHA reported 39 trench-related deaths, more than doubling the 15 recorded in 2021. In response, OSHA launched a national enforcement program in June 2022, focusing on:
- Enhanced reporting and recording of inspections
- Development of outreach programs
- Updated National Emphasis Program (NEP) on trenching safety
- Creation of new compliance assistance resources
These measures reduced trench-related fatalities to 14 in 2023, but with 4 deaths already in early 2024, vigilance is still needed.
Industry Initiatives
The industry continues to improve awareness and practices:
- June 2024 was declared Trench Safety Month by the National Utility Contractors Association.
- "Shore Up for Safety Week" in May promoted safety awareness and training.
- Organizations like NAXSA are promoting safe excavation practices.
Despite these efforts, trench collapses have claimed 90-100 lives over the past five years. It's our responsibility to prioritize safety and implement robust programs to protect workers.
Best Practices for Trenching Safety Programs
Develop a Comprehensive Safety Plan
- Assign roles and responsibilities.
- Outline protective systems for various trench depths and soil types.
- Establish communication protocols and emergency response procedures.
Implement Proper Protective Systems
- Use appropriate systems based on trench depth and soil conditions.
- For trenches 5-20 feet deep, use sloping, benching, shoring, or shielding.
- For trenches deeper than 20 feet, systems must be designed by a registered professional engineer.
- Never allow workers to enter an unprotected trench.
Conduct Regular Inspections
- Inspect trenches daily and after environmental changes.
- Check for signs of potential cave-ins and test for hazardous atmospheres.
- Keep heavy equipment and excavated materials at least 2 feet from trench edges.
Provide Comprehensive Training
- Train all workers on trench hazards and safety procedures.
- Ensure competent persons receive specialized training.
- Conduct regular refresher courses.
Utilize Alternative Methods When Possible
- Explore trenchless technologies like directional boring or pipe ramming.
- Evaluate utility tunneling for larger projects.
Foster a Safety-First Culture
- Encourage open communication and empower workers to prioritize safety.
- Promote "stop work" authority for unsafe conditions.
- Discuss safety concerns and near-misses regularly.
- Recognize and reward safe behaviors.
Key Safety Reminders
- Never enter an unprotected trench.
- Trenches can collapse suddenly without warning.
- A protective system must be in place for trenches 5 feet deep or greater.
- Use proper sloping, benching, shoring, or shielding to prevent cave-ins.
Remember, no job is so urgent that we can't take the time to do it safely. Stay safe and let's work together to make our industry safer for everyone.
