This dramatic footage from a CCTV camera in China shows why it is important to follow the appropriate health and safety procedures and wear personal protective clothing when dealing with drains.
It is not clear what the lady in the brief film clip was trying to do but at first sight it seems she was using a stick to clear a blocked drain when it exploded in her face, apparently as the result of a build-up of methane.
Such hazards are thankfully rare but they do exist. Drain Doctor technicians are trained and equipped to deal safely with drain blockages and other plumbing and drainage problems.
