An explosion at the Cerredo mine in Degaña has led to the tragic deaths of five miners, with another four sustaining injuries of varying severity. The preliminary investigation suggests that methane gas accumulation could be the cause. According to the government delegate in Asturias, Adriana Lastra, both the Mining Rescue Brigade and the Judicial Police are exploring this scenario.

Methane, or grisú, constitutes over ninety percent of this dangerous gas, making it highly flammable and capable of forming explosive mixtures with air. This gas can lead to rapid asphyxiation, often before workers can react adequately. Measures are typically in place to monitor and control methane levels within mines, yet the risk remains significant.

Historically, grisú has triggered numerous fatalities in the mining industry due to its explosive nature. Constant ventilation and monitoring are essential in preventing dangerous accumulations of methane. The tragedy in the Cerredo mine serves as a stark reminder of the hazards miners face daily, underscoring the importance of stringent safety protocols.

Mining accidents related to methane have occurred throughout history, with some of the worst tragedies resulting in multiple fatalities. The Cerredo incident emphasizes the critical need for ongoing safety improvements and effective emergency response measures in the mining sector.
