Cut off the source of leakage as much as possible to prevent entry into restricted spaces such as sewers and flood drains
.
A small amount of overflow: mix with sand, dry lime or soda ash
.
A large number of leaks: build a dike or dig a pit for storage; spray water to cool and dilute the steam to dilute the leaked material into incombustibles
