On Thursday, a boy in Zizhong county, Sichuan province, accidentally caused a septic tank explosion by throwing firecrackers into it, flipping nearby vehicles. Several cars were damaged, but fortunately, no injuries were reported. The boy and his parents have been taken in by the police for investigation.
Urban sewers produce flammable gases like methane, hydrogen sulfide, and ammonia, which can easily ignite and explode when exposed to fire and air. Long-abandoned sealed wells can lead to even more powerful explosions. Similarly, unextinguished cigarette butts, matches, and other sources of ignition, even if not thrown into the well, can also lead to the same consequences.
During festivals, stay away from places like biogas tanks and sewers when setting off fireworks. Children should always be supervised by parents while lighting them to prevent accidents.
