Biogas can be explosive when mixed in the ratio of one part biogas to 8–20 parts air Special safety precautions have to be taken for entering an empty biogas digester for maintenance work It is important that a biogas system never has negative pressure as this could cause an explosion Negative gas pressure can occur if too much gas is
