What safety measures should be paid attention to when building biogas digesters?

When building biogas digesters, we should strictly abide by the operating rules to prevent accidents. ① Prevention of landslide: Under normal circumstances, the pool foundation with good soil quality and low groundwater level may not leave slope on the pool wall. It is forbidden to dig "hollow caves" with concave top and convex bottom. For soft soil and sandy soil with poor soil quality, reinforcement measures should be taken to prevent landslides. When the groundwater level is high or in rainy season, drainage ditches should be set around the pit or deep puddles should be dug in the pool to divert water. (2) Preventing people from being injured: When digging and transporting stones and building pits, it is necessary to prevent stones from falling and bricks and tools from falling, which may injure the construction workers by accident. Ropes for transporting stones and scaffolding must be strong and firm to prevent people from breaking and falling from scaffolding. (3) It is forbidden to use naked light in the construction of pool body: it is forbidden to use naked light in the construction of biogas digesters, and electric lights can be used for construction. And prevent electric leakage to prevent electric shock. ④ Strict inspection: When scrubbing in the pool, carefully check whether there are cracks on the top and wall of the pool, and check whether there are stones and bricks that are easy to fall off. If problems are found, deal with them in time. ⑤ Covering in time: After the biogas digester is completed, the water inlet, water outlet and skylight should be covered in time to prevent people and animals from falling into the pool.
