Confined Spaces in Underground Construction

January 21, 2025

Confined spaces present unique challenges and risks in the field of underground construction. Recognizing these risks and implementing effective safety measures is not just a regulatory requirement but a critical component of protecting your workforce. Here’s what companies need to know, do, and educate about confined spaces.


What You Need to Know

Definition of Confined Space: A confined space is an area that:

  • Is large enough for workers to enter and perform tasks.
  • Has limited or restricted means of entry or exit.
  • Is not designed for continuous occupancy.


Types of Confined Spaces:

  • Non-permit confined spaces: These spaces do not pose significant hazards.
  • Permit-required confined spaces: These involve hazards such as:
  1. Atmospheric dangers (e.g., oxygen depletion, toxic gases like hydrogen sulfide).
  2. Risks of engulfment.
  3. Entrapment or asphyxiation potential.
  4. Other serious health or safety threats.


Regulatory Requirements:

  • OSHA mandates continuous atmospheric monitoring in confined spaces whenever possible.
  • Permits must be issued for work in spaces with specific hazards, and companies must retain these permits for at least one year for potential OSHA review.
  • A competent person must evaluate job sites to identify confined spaces and hazards.


What You Need to Do

  1. Develop a Confined Space Plan:
  • Identify all confined spaces on job sites.
  • Clearly label and communicate confined spaces to workers.
  1. Implement Monitoring and Equipment Protocols:
  • Use continuous atmospheric monitors to detect hazards like oxygen depletion and toxic gases.
  • Equip workers with proper safety gear, including harnesses and ventilation equipment.
  1. Establish Rescue Plans:
  • Define protocols for self-rescue, non-entry rescue, and entry rescue.
  • Train rescue personnel annually and ensure documentation is up to date.
  • Avoid sole reliance on external emergency services, which can delay rescue operations.
  1. Assign Clear Roles:
  • Designate entrants, attendants, and supervisors for confined space work.
  • Ensure roles are well-defined and communicated to all team members.


What You Need to Educate

  1. Train Workers Effectively:
  • Provide training in a language and vocabulary workers understand.
  • Educate workers on the hazards of confined spaces, including atmospheric dangers and physical risks.
  1. Educate on Regulatory Compliance:
  • Teach workers the importance of permits and the conditions under which they are required.
  • Emphasize the role of competent persons and the responsibilities of controlling contractors.
  1. Promote Vigilance and Communication:
  • Reinforce the importance of staying vigilant, even with repeated tasks.
  • Foster a culture of clear communication among team members to identify and address hazards promptly.
  1. Highlight the Risks:
  • Discuss specific risks, such as:
  • Oxygen depletion due to curing concrete.
  • Hydrogen sulfide buildup from degrading organic material.
  • Engulfment dangers in unstable environments.


Conclusion

Understanding and addressing the risks of confined spaces in underground construction is an ongoing process. Companies must prioritize knowledge, action, and education to safeguard their teams. With proper planning, monitoring, and training, you can ensure compliance with regulations and, more importantly, protect the lives of your workers.

The underground utility and construction industries are built on teamwork, resilience, and a commitment to getting the job done. But while we spend a great deal of time discussing physical safety, we often spend far less time talking about mental health. That needs to change. Recently, WUCA members had the opportunity to participate in VitalCog Training from Bruce Morton. The message was both sobering and hopeful: suicide is a significant challenge within our industry, but it is also preventable. One statistic stood out. Suicides in construction occur at a rate approximately six times higher than work-related fatalities. While our industry has made tremendous progress in reducing physical hazards, the hidden dangers of isolation, depression, anxiety, substance misuse, and hopelessness continue to affect many workers, supervisors, and business owners. Understanding the Risk Suicide is rarely caused by a single event. Instead, it often develops from a combination of circumstances and feelings. According to suicide risk models discussed during the presentation, risk factors frequently include: Feeling alone or disconnected from others Feeling like a burden to family, friends, or coworkers A desire to escape emotional pain permanently An increased capability for self-harm, often accompanied by reduced fear of death, risk-taking behaviors, or access to lethal means These feelings can affect anyone, regardless of experience, position, age, or reputation. Warning Signs to Watch For One of the most important things we can do is recognize when someone is behaving differently than normal. Potential warning signs include: Talking about wanting to die or expressing hopelessness Giving away possessions or "tying up loose ends" Having unusually deep conversations that seem like goodbyes Significant changes in mood or behavior Withdrawal from coworkers, family, or friends Increased use of alcohol or drugs Changes in personal appearance or self-care Sudden changes in work performance Taking unusual interest in financial matters, wills, or final arrangements Trust your instincts. When something feels off, it often is. Supporting Mental Health Every Day Preventing suicide starts long before a crisis develops. Small actions can have a significant impact on mental well-being. 1. Practice Active Listening Many people don't need someone to solve their problems. They need someone who will truly listen. Put down the phone, eliminate distractions, and focus on understanding what the person is saying. Sometimes the simple act of being heard can make a meaningful difference. 2. Lean on Your Tribe Healthy relationships are one of the strongest protective factors against suicide. Invest time in the people who support you and encourage others to do the same. Equally important, look for opportunities to support others. Giving back strengthens connections and reminds people they matter. 3. Make Time for Stress Relief Whether it is hunting, fishing, coaching youth sports, exercising, spending time with family, or pursuing a hobby, everyone needs healthy outlets. Taking care of your mental health is not a sign of weakness. It is part of staying fit for work and life. 4. Encourage One Another A simple check-in can go a long way. Ask a coworker how they are doing. Follow up. Take the extra minute to listen. Encouragement and connection build stronger crews and healthier workplaces. Understanding the "Three P's" P ervasive – Feeling like problems affect every area of life. P ermanent – Believing things will never improve. P ersonal – Viewing setbacks as personal failures. When someone becomes trapped in this mindset, hope can begin to disappear. That is why reminding people that challenges are temporary, solutions exist, and support is available can be incredibly powerful. What to Do if Someone Talks About Suicide If someone trusts you enough to share thoughts of suicide, take it seriously. Here are several important steps: Thank Them for Sharing Opening up about suicidal thoughts is extremely difficult. Acknowledge the courage it took to talk. Listen Without Judgment Avoid arguing, lecturing, or immediately trying to solve the problem. Focus on understanding and connecting. Offer Hope Hope is the antidote to suicide. Remind the person that help is available, circumstances can change, and they do not have to face their struggles alone. Reinforce Their Value Many people experiencing suicidal thoughts feel like a burden. Be direct. Tell them they matter. Tell them they are not alone. Tell them their life has value. Connect Them to Help If you are not equipped to provide ongoing support, help connect them with someone who can. This may be: A trusted family member A friend A supervisor An employee assistance program A mental health professional The 988 Suicide & Crisis Lifeline Most importantly, follow up. Continuing to check in shows that you care and helps reinforce connection. If the Risk Is Immediate If someone tells you they intend to kill themselves imminently or you believe they are in immediate danger, call 911 immediately . Emergency intervention is necessary when a life is at risk. Building a Culture of Care The construction industry has always thrived because people look out for one another. We wear PPE, follow safety procedures, and stop unsafe work because every person on the crew matters. Mental health deserves that same commitment. At WUCA, we encourage every member company, owner, supervisor, and employee to make mental well-being part of the safety conversation. A simple conversation, a check-in, or a willingness to listen could save a life.  Need help now? Call or text 988 to reach the Suicide & Crisis Lifeline, available 24/7.
