What safety problems should be paid attention to when entering biogas digesters for maintenance?

First, pay attention to fire prevention. When the movable cover is uncovered, no fire source shall be used around the biogas digester, and it is forbidden to use open flames and articles emitting electric sparks when entering the pool.

Second, we should pay attention to prevent suffocation poisoning. Ventilation and convection must be carried out for a period of time before entering the pool. Ensure that there is no biogas and toxic gas in the pool, and only after someone outside the pool is supervised can you enter the pool.
