What safety precaution should you take when working with digester gas?

When working with digester gas, it is crucial to use a proper mask and keep any flame away due to the highly volatile and potentially explosive nature of the gas. Digester gas, which is primarily composed of methane, can present significant health and safety risks, including fire and explosion hazards, if not handled properly. A proper mask helps to protect against inhalation of harmful gases or vapors that may be present in the work environment. Additionally, keeping flames away is essential because methane is flammable and can ignite easily, leading to dangerous situations.

While other safety measures like using protective gloves and goggles, ensuring there are no electrical appliances nearby, and working outdoors can contribute to a safer working environment, they do not directly address the immediate hazards posed by the combustion and toxic properties of digester gas. Therefore, utilizing a proper mask and avoiding open flames are the most critical precautions when dealing with this type of gas.
