A construction site in New Haven, Connecticut, turned hazardous as 14 individuals faced hospitalization due to perilously high carbon monoxide levels during a renovation project. The alarming incident originated from a propane-fueled saw cutting concrete without adequate ventilation. Emergency services responded after a worker collapsed, revealing extreme carbon monoxide levels. A critical situation unfolded, leading to hospitalizations, with one worker in serious condition. The emergency operations director noted the disaster narrowly averted, emphasizing the severity of the incident and the potential for more significant harm.


In a chilling episode at a construction project in New Haven, Connecticut, 14 individuals found themselves grappling with the silent menace of carbon monoxide poisoning. The incident unfolded during the renovation of a building, sending shockwaves through the construction site.

Emergency services rushed to the scene, located at the Yale University Security center, following the collapse of a worker on a fateful Wednesday. The cause of the distressing situation was traced back to a propane-fueled saw utilized for cutting concrete, operating without adequate ventilation. This oversight resulted in the accumulation of potentially fatal levels of carbon monoxide within the building.

The worker, discovered with alarmingly high levels of carbon monoxide in his bloodstream, was swiftly transported to Jacobi Medical Centre’s hyperbaric chamber in the Bronx. Despite immediate intervention, the individual remains in critical condition, underscoring the severity of carbon monoxide exposure.

Upon revisiting the construction site, responders made a startling discovery – 13 additional individuals experiencing headaches, indicative of elevated carbon monoxide levels. The emergency services promptly transported them to the hospital, where assessments revealed one worker in a serious condition, four discharged, and eight admitted for treatment.

Rick Fontana, New Haven’s emergency operations director, commented on the gravity of the situation, highlighting the potential catastrophe narrowly averted. The concentration of carbon monoxide in the affected area reached 350 parts per million, a staggering ten times the permissible level.

Among the 14 individuals requiring hospitalization, nine were construction workers, while five belonged to the Yale Security Department, sharing the facility with the construction project. The incident serves as a stark reminder of the inherent dangers posed by carbon monoxide, an insidious threat that hinders the body's oxygen utilization and poses severe risks to vital organs, including the heart and brain.


The construction site in New Haven became a battleground against an invisible foe as 14 individuals confronted the dangers of carbon monoxide poisoning. Triggered by a propane-fueled saw operating without proper ventilation, the incident unfolded with a worker collapsing, setting off a chain of events that led to multiple hospitalizations. Swift intervention prevented a potential disaster, with emergency services revealing carbon monoxide concentrations ten times the permissible level. The critical condition of one worker underscores the severity of the exposure. This chilling episode serves as a poignant reminder of the silent threats lurking on construction fronts, necessitating heightened safety measures to avert potential catastrophes.
