All suction and discharge hoses will be tested quarterly as follows:
1. Place the hose on a large, clean and dry surface. Seal the far end of the hose with a dust
cap or dust plug fitted with a pet cock or valve for use in relieving internal pressure. Check the
cam levers to insure that they are in the fully locked (down) position.

cam levers to insure that they are in the fully locked (down) position.
3. Inflate the hose until the internal pressure reaches 150 pounds. WARNING: Be sure
that all personnel stand clear of the hose ends while the hose is being inflated, Allow the
inflated hose to stand for a period of 15 minutes.
4. Examine the hose and fittings for any signs of damage or deterioration. (Cracked
fittings, delamination, blistered coating material, exposed braid).

unserviceable.
WARNING: Relieve the internal pressure by opening the pet cock prior to attempting to
