a) CONNECT HOSES OF SUFFICIENT LENGTH TO REACH ACROSS THE ROOM CONTAINING FIRE. THE WATER SUPPLIES SHOULD BE TAKEN FROM SEPARATE HYRANTS, AND Y PIECES SHOULS NOT BE USED

EMPLOYEES HEALTH SAFETY INSTITUTEb) PREFERABLY, THE HYDRANTS SUPPLYING TO WATRER

WALL OPERATORSAND FIRE FIGHTERS SHOULD BE FED FROM SEPERATE PUMPS

C) CONNECT CORRECT NOZZLES WITH HOISES FOR WATER WALL OPEARTORS AND FIRE FIGHTERS RESPECTIVELY

d) IF A LIQUID FUEL FIRE IS SUSPECTED, FOAM – MAKING BRANCH PIPE WITH AQN INLINE INDUCTION IS TO BE USED INSTEAD OF NOZZLES BY THE FIGHTER

e) IF FOAM IS TO BE USED, IMSERT THE SPILL PICK UP INTO THE CONTAINER OF AFFF 20 LITRE CONTAINER

f) IF THE DOOR OPEND AWAY FROM THE FIRE FIGHTER A WIRE ROPE SHOULD BE ATTACHED TO THE HANDLE SO THAT THE DOOR CAN BE PULLED QUICKLY, IF NECCESSARY
