A tragic industrial accident in Mobile, Alabama has claimed the lives of two workers and injured a third, following a suspected gas exposure incident inside a manhole during sewer line work. The event occurred on August 11, 2025, near Princeton Woods Drive East, off Howells Ferry Road.
According to officials, the workers—employed by Construction Labor Services—were subcontracted on a project for the Mobile Area Water and Sewer System (MAWSS). The crew was reportedly preparing to bypass a sewer line as part of a pipe replacement effort when the incident occurred.
According to public reports, one worker initially fell into a 20-foot manhole. A second worker entered the confined space to assist and also became unresponsive. A third worker attempted rescue but became disoriented and began climbing out of the space as emergency crews arrived. The two trapped workers—identified as 31-year-old Garrett Robertson and 50-year-old Herber Rivas—were pulled from the manhole and later pronounced dead. The third worker was transported to a hospital; his condition has not been released.
Authorities believe the cause of the incident was toxic gas exposure, possibly hydrogen sulfide—a known hazard in sewer systems.
The Hazards of Confined Space Entry
Confined space work, especially within sewer systems, is inherently dangerous. These environments often contain hazardous gases such as methane or hydrogen sulfide, both of which can displace oxygen and lead to rapid unconsciousness or death.
This case exemplifies the dangers that arise when:
- Atmospheric testing is inadequate or skipped
- Ventilation systems are not used or fail
- Rescue procedures are not executed with proper protective gear
Federal safety standards require atmospheric monitoring and ventilation before entry. Employers must also develop detailed rescue plans to comply with OSHA’s confined space regulations.
Legal and Safety Implications
This fatal incident may result in scrutiny from federal and state regulators. Similar accidents often trigger investigations into whether employers followed proper safety procedures, including the use of personal protective equipment, gas detection instruments, and rescue protocols.
Failure to adhere to required standards can lead to citations and fines, particularly in industries with a history of chemical plant explosion risks, and toxic exposure, during confined space operations.
Families of deceased or injured workers may be entitled to workers’ compensation, but in some cases, additional legal remedies may be available—especially if a third-party contractor or equipment manufacturer contributed to the hazardous condition.
FAQ: What to Do After a Confined Space Work Accident
Q: What should families do after losing a loved one in an industrial accident involving toxic gas exposure?
Families should consult a workplace injury lawyer or industrial accident lawyer experienced in confined space fatalities. These attorneys can investigate the employer’s safety practices and evaluate potential third-party liability.
Q: Can families pursue more than just workers’ compensation?
Yes. If the accident involved defective safety equipment or negligent third-party contractors, a third-party liability claim may be appropriate in addition to workers’ compensation benefits.
Q: Who investigates these types of accidents?
The Occupational Safety and Health Administration (OSHA) typically conducts investigations. Their findings can provide key evidence in determining whether the company complied with federal safety regulations.
Q: Are there warning signs of gas exposure?
Yes. Sudden dizziness, disorientation, headaches, or unconsciousness are immediate red flags. Workers should never enter confined spaces without atmospheric testing and appropriate safety gear.
