At midday on Tuesday,March 11,2025,a devastating collapse occurred during an excavation on Insurgentes Avenue in Chetumal,resulting in the deaths of two workers. This incident has prompted a swift response from local authorities and raised concerns about safety protocols.
Details of the Chetumal Excavation Collapse
According to preliminary reports from the secretaría de Seguridad Ciudadana de Quintana Roo, the accident took place while workers were engaged in excavation work on Avenida Insurgentes, between cornelio Lizárraga and Aaron Merino, in the municipio de Othón P. Blanco. The nature of the work involved a trench that ultimately proved unstable.
in response to the emergency, authorities from Protección civil, firefighters, and medical personnel mobilized to conduct a rescue operation. The immediate priority was to reach the trapped workers and provide any possible assistance.
Confirmation of Fatalities
Personnel from the Secretaría de Seguridad Ciudadana confirmed the tragic deaths of two individuals,both of whom were workers. They became trapped under the mud and stones following the collapse. The scene was one of intense activity as emergency responders worked to recover the bodies.
Peritos from the Fiscalía General del Estado (FGE) carried out the removal of the bodies, initiating the formal process of examination and identification. The FGE will be responsible for determining the precise cause of the collapse and whether any negligence contributed to the accident.
CAPA’s Statement on the Incident
The Comisión de Agua Potable y Alcantarillado (CAPA) released a statement via social media, indicating that the workers died “during the works of rehabilitation of the sanitary system in the city of chetumal.” the statement further explained that a trench of three meters in depth opened as a outcome of the softening of the ground.
Según los reportes preliminares, los trabajadores contaban con el equipo de seguridad y protección personal requerido, incluyendo líneas de vida
CAPA added in its statement, suggesting that initial assessments indicate safety measures were in place. However, the effectiveness of these measures is now under scrutiny.
CAPA concluded by stating that they are closely monitoring the situation and that the responsible company to which the collaborators belonged “se encuentra dando el completo apoyo, acompañamiento y atención a las familias de los deudos,” indicating that support is being provided to the families of the deceased.
Ongoing Investigation
The investigation into the Chetumal excavation collapse is ongoing. authorities will be examining all aspects of the incident, including soil conditions, safety protocols, and the actions of all parties involved. The goal is to determine the root cause of the collapse and prevent similar tragedies in the future.
Excavation Collapse in Chetumal: Q&A on Safety and Prevention
The tragic excavation collapse in chetumal on March 11, 2025, which resulted in the deaths of two workers, has brought excavation safety into sharp focus. This Q&A article addresses key questions surrounding the incident and, more importantly, what measures can be taken to prevent similar tragedies in the future.
Understanding the Chetumal Excavation Collapse
What happened in the Chetumal excavation collapse?
On March 11,2025,two workers died in Chetumal,Quintana Roo,Mexico,when an excavation trench collapsed on Avenida Insurgentes. The workers were trapped under mud and stones.The excavation was part of a project to rehabilitate the city’s sanitary system.
Where did the Chetumal excavation collapse occur?
The collapse happened on Avenida Insurgentes, between Cornelio Lizárraga and Aaron Merino, in the municipio de Othón P. Blanco, Chetumal, Mexico.
What was the depth of the trench that collapsed?
According to the Comisión de Agua Potable y Alcantarillado (CAPA), the trench was three meters (approximately 9.8 feet) deep.
What caused the Chetumal excavation collapse?
The collapse resulted from the softening of the ground in the 3-meter-deep trench. An ongoing inquiry seeks to determine the precise cause and whether negligence played a role. Factors under investigation likely include soil conditions and adherence to safety protocols.
Multiple agencies responded, including:
Secretaría de Seguridad Ciudadana de Quintana Roo
Protección Civil
Firefighters
Medical personnel

Trenching and excavation safety: Key Questions and Answers
What are the primary hazards associated with trenching and excavation work?
The most significant risk is trench collapse, which can lead to severe injury or death by burial. Other hazards include:
Falls: Workers can fall into the excavation.
Falling loads: Equipment or materials can fall into the trench.
Hazardous Atmospheres: Trenches can accumulate toxic gases or lack sufficient oxygen.
Equipment Hazards: Accidents involving excavators and other heavy machinery.
What are the key safety measures to prevent trench collapse?
OSHA (Occupational Safety and Health Management) and other safety organizations mandate the use of protective systems in trenches deeper than 5 feet unless the excavation is made entirely in stable rock.[1] These systems include:
Sloping: Cutting back the trench walls at an angle to reduce soil pressure.The angle depends on soil type and depth.[3]
Shoring: Installing supports, such as hydraulic jacks or timbers, to brace the trench walls.
Trench Shields (Trench Boxes): Using portable steel or aluminum structures to protect workers from cave-ins.
What is “sloping” in the context of excavation safety?
Sloping involves excavating the trench walls at an angle to reduce soil pressure preventing collapse. The exact angle of the slope depends majorly on conditions such as soil type and depth [3]
What role does a “competent person” play in excavation safety?
A “competent person” is designated by the employer and has specific responsibilities, including:[1]
Inspecting trenches daily for hazards.
Classifying soil types to determine appropriate protective systems.
Ensuring protective systems are installed correctly.
Removing standing water and preventing water accumulation.
Conducting air monitoring for hazardous atmospheres, when necessary.
What are the different types of protective systems used in trenching, and how do they work?
| Protective System | Description | How it Works |
| :—————- | :———————————————————————————————————- | :——————————————————————————————————————————————- |
| sloping | Excavating trench walls at a safe angle of repose.| Reduces soil pressure on the trench walls by creating a stable slope,preventing the soil from collapsing into the excavation.|
| Shoring | Installing temporary supports such as hydraulic jacks, timbers, or steel plates to brace trench walls. | Provides a physical barrier that supports the trench walls, preventing them from collapsing inward due to soil pressure and instability.|
| Trench Shields | Using portable, box-like structures to shield workers. | Protects workers by creating a safe zone within the shield. If a collapse happens, the shield bears the force preventing injury.|
What does OSHA say about excavation safety?
OSHA has strict guidelines to prevent fatalities from trench collapses. Some key OSHA requirements include:[1,2]
Protective Systems: Trenches 5 feet (1.5 meters) or more in depth require a protective system.
inspections: Daily inspections of excavations by a competent person.
Safe Access and Egress: Safe ways for workers to enter and exit the trench.
Hazardous Atmospheres Testing: Testing for oxygen deficiency and hazardous substances in trenches deeper than 4 feet.
Surface Encumbrances: Ensuring that surface encumbrances are either removed or supported to
