*Mobile, Alabama* — In a devastating turn of events early Monday morning, two contractors lost their lives while working on a sewer bypass project in the Princeton Woods area of Mobile. The victims, identified as 50-year-old Herber Rivas and 31-year-old Garrett Robinson, were part of a crew installing an 18-inch sewer line near Eight Mile Creek — a project awarded to Construction Labor Services under a $2.3 million contract by the Mobile Area Water and Sewer System (MAWSS).
**Timeline of the Incident**
At approximately 8:23 a.m., Robinson descended into a manhole to continue work on the bypass. Moments later, he became unresponsive, likely due to exposure to toxic gas. Rivas, witnessing his colleague in distress, bravely entered the confined space to assist — but was also quickly overcome. A third worker followed in an attempt to help but managed to escape after becoming disoriented. He was treated on-site and later hospitalized.
**Emergency Response**
Mobile Fire-Rescue Department’s Technical Rescue Team arrived swiftly, deploying breathing apparatuses and specialized equipment to retrieve the victims. Despite their efforts and rapid transport to a nearby hospital, both Rivas and Robinson were pronounced dead shortly after arrival.
**Suspected Cause**
While the exact nature of the gas remains under investigation, officials suspect hydrogen sulfide — commonly known as “sewer gas” — played a role. This colorless, highly toxic substance is a known hazard in sewer systems. Monica Allen, spokesperson for MAWSS, emphasized the ever-present danger of such gases in confined utility workspaces. A crew from Spire Inc. later confirmed no residual gas was present when rescue teams entered the site.
**Ongoing Investigation**
The Occupational Safety and Health Administration (OSHA) has launched a formal investigation into the incident. Interim Fire-Rescue Chief Barry Glisson briefed city council members, commending the rescue team’s swift action and confirming that safety protocols, including gas testing and protective gear, were in place during the recovery.
**Community Impact**
The deaths of Rivas and Robinson have sent ripples of grief through Mobile’s tight-knit construction and utility community. Both men were known for their dedication, courage, and camaraderie — qualities that ultimately led them to make the ultimate sacrifice. Vigils and tributes have begun to emerge across the city, honoring their lives and the risks faced daily by workers in hazardous environments.
⚠️ **A Sobering Reminder**
This tragedy underscores the critical importance of rigorous safety measures in confined space operations. Experts continue to advocate for enhanced training, real-time gas monitoring, and emergency preparedness to prevent future incidents.
As Mobile mourns, the legacy of Herber Rivas and Garrett Robinson stands as a solemn testament to the bravery and selflessness of those who build and maintain the infrastructure we often take for granted.
