Is it true that excavating through a landfill site necessitates testing of the excavation atmosphere?

Excavating through a landfill site necessitates testing of the excavation atmosphere due to the potential presence of hazardous gases and contaminants. Landfills can be sources of methane, carbon dioxide, and other volatile organic compounds, which can pose health risks to workers if inhaled. Testing for these gases is essential to ensure the safety of the workers and to maintain compliance with health and safety regulations. By assessing the atmosphere before and during excavation, appropriate safety measures, such as ventilation and personal protective equipment, can be implemented to mitigate any risks associated with working in such environments. Therefore, the answer is true, emphasizing the importance of conducting atmosphere testing in landfill excavation scenarios.
