If for any reason the flow of water is suddenly shut off, the ladder will be subjected to severe structural stresses and strains; therefore the recommended procedure is to supply a ladder pipe?
TWO SEPARATE SOURCES OF WATER
If for any reason the flow of water is suddenly shut off, the ladder will be subjected to severe structural stresses and strains; therefore the recommended procedure is to supply a ladder pipe from two separate sources of water (pumper, fireboat).
