Managing High-Voltage Hazards Beneath a Steel Deck

Issue:

A major safety risk was uncovered during a roofing project, with high-voltage lines and fiber-optic cables positioned directly under a steel deck. Without proper precautions, any penetration of the deck could have caused severe electrical incidents, operational disruptions and potential risks to human life.

The situation presented the following risks:

• Operational Disruptions: A single penetration into a critical high-voltage or communication line could have caused a total plant shutdown.
• Severe Safety Hazards: Crew members were at risk of electrocution, which could result in serious injury or fatality.
• Financial and Infrastructure Losses: Damage to vital electrical and communication infrastructure could have led to extensive repair costs and delayed project timelines.

Specifically, approximately 300 feet of the steel deck presented these high-risk conditions.

Solution:

To address this hazardous situation, Benchmark coordinated a comprehensive safety strategy, ensuring careful collaboration between the roofing contractor, the electrical contractor, and Benchmark's expert team.

Key actions taken included the following steps:

Locating and Marking Critical Zones

High-voltage lines and fiber-optic cables beneath the steel deck were identified and accurately located using advanced detection tools. These zones were then transferred to the top surface and clearly marked to ensure visibility and safety for the roofing crew.

Enhanced Crew Monitoring and Training

Crew members received detailed instructions on staying aware of marked zones to prevent accidental penetration. Fastener placement and positioning were monitored closely throughout the project. Additionally, workers were briefed on potential hazards related to the lines and educated on emergency procedures to ensure a safe working environment.

Impact:

Through meticulous planning and precise execution, the roofing project was successfully completed with no safety incidents or operational disruptions. The team demonstrated a strong commitment to safety by eliminating the risk of electrocution, ensuring no contact with high-voltage lines. This proactive measure effectively mitigated a critical safety hazard and safeguarded the well-being of all personnel.

By protecting electrical and fiber-optic lines from damage, the project avoided costly repairs and prevented unscheduled plant shutdowns or operational delays, delivering cost-effective results while maintaining the integrity of essential infrastructure.

The successful management of high-voltage hazards in this project underscores Benchmark’s commitment to safety, precision, and client-focused solutions. By prioritizing detailed planning, comprehensive training, and real-time monitoring, Benchmark ensured the completion of a high-risk project without a single incident.
