Quebec farmer died from acute asphyxia due to exposure to hydrogen sulfide
A recent coroner’s report sends a clear warning to Quebec’s agricultural sector: more must be done to protect workers from the deadly gases present in manure pits. On October 4, 2024, a 44-year-old farmer in Sainte-Christine loses his life after entering a manure pit to unclog a pipe. The tragedy, detailed in a newly released investigation report by coroner Nancy Bouchard, exposes critical gaps in safety practices and awareness.
Lack of protection and training proves fatal
Bouchard’s report reveals the farmer enters the pit without proper protective equipment or ventilation. Moments later, his wife finds him unconscious. Emergency services rush him to the hospital, but he does not survive.
An autopsy and toxicological analysis confirm the cause of death: acute asphyxia due to exposure to hydrogen sulfide (H₂S), a toxic gas commonly produced in manure pits. “Even brief exposure to high concentrations of hydrogen sulfide can be fatal,” says Bouchard.
The coroner’s analysis points to a lack of preventive measures. “The absence of adequate protective equipment and proper ventilation contributed to the accident,” Bouchard states. She notes the farmer had not received specific training on the risks or safe procedures for entering manure pits.
Recommendations for the agricultural sector
Bouchard’s recommendations target the Union des producteurs agricoles (UPA), calling for urgent action to prevent future tragedies. “I recommend that the Union des producteurs agricoles implement awareness actions among its members regarding the importance of wearing the required protective equipment when entering a manure pit,” she writes. She also urges the UPA to establish or update regular communications about the dangers of hydrogen sulfide gas, referencing the need for “an appropriate frequency of information on the presence of toxic gases in manure pits.”
Call to action for health and safety leaders
For health and safety leaders in agriculture, the message is unmistakable: robust training, proper ventilation, and mandatory use of protective equipment are non-negotiable. Bouchard’s report serves as a stark reminder that “every entry into a manure pit carries major risks,” and that only strict adherence to safety protocols can prevent similar losses.
As the agricultural industry continues to evolve, Bouchard’s findings and recommendations set a clear path forward—one where worker safety stands at the forefront of every operation.
