General Information
*
Woven jacket fire hose should be tested in accordance with the service test provisions contained in the current edition of National Fire Protection As-
sociation Bulletin No. 1962 - Standard for the Care, Use and Service Testing of Fire Hose.
Care, Maintenance and Storage

5.
Provisions must be made to protect testing
personnel from the forces of the pressure media
if a failure occurs.
6.
Testing personnel must never stand in front of
or in back of the ends of a hose being pressure
tested.
7.
When liquids such as gasoline, oil, solvent or
other hazardous fluids are used as the test fluid,
precautions must be taken to protect against
fire or other damage should a hose fail and the
test liquid be sprayed over the surrounding
area.
The Rubber Manufacturers Association (RMA) has
published separately a series of Hose Technical
Information bulletins describing Maintenance,
Testing and Inspection recommendations.
Reference should be made to the current RMA
Catalog of Publications to determine the availability
of the latest edition. Bulletins published as of
January 2003 include the following:
Publication No.
IP 11-1-Steam Hose
IP 11-2-Anhydrous Ammonia Hose
IP 11-4- Oil Suction and Discharge Hose
IP 11-5-Welding Hose
IP 11-7-Chemical Hose
IP 11-8- Fuel Dispensing Hose
Storage
Rubber hose products in storage can be affected
adversely by temperature, humidity, ozone,
sunlight, oils, solvents, corrosive liquids and fumes,
insects, rodents and radioactive materials.
The appropriate method for storing hose depends
to a great extent on its size (diameter and length),
the quantity to be stored and the way in which it
is packaged. Hose should not be piled or stacked
to such an extent that the weight of the stack
creates distortions on the lengths stored at the
bottom. Since hose products vary considerably
in size, weight and length, it is not practical to
establish definite recommendations on this point.
Hose having a very light wall will not support as
much load as could a hose having a heavier wall
or hose having a wire reinforcement. Hose which is
shipped in coils or bales should be stored so that
the coils are in a horizontal plane.
Whenever feasible, rubber hose products should
be stored in their original shipping containers,
especially when such containers are wooden
crates or cardboard cartons which provide some
protection against the deteriorating effects of oils,
solvents and corrosive liquids; shipping containers
also afford some protection against ozone and
sunlight. Certain rodents and insects will damage
rubber hose products, and adequate protection
from them should be provided.
Cotton-jacketed hose should be protected against
fungal growths if the hose is to be stored for
prolonged periods in humidity conditions in excess
of 70%.
The ideal temperature for the storage of rubber
products ranges from 50°F to 70°F (10°C to 21°C)
with a maximum limit of 100°F (38°C). If stored
below 32°F (0°C), some rubber products become
stiff and would require warming before being
placed in service. Rubber products should not
be stored near sources of heat, such as radiators,
base heaters, etc., nor should they be stored under
conditions of high or low humidity.
To avoid the adverse effects of high ozone
concentration, rubber hose products should not
be stored near electrical equipment that may
generate ozone or be stored for any lengthy
period in geographical areas of known high ozone
concentration. Exposure to direct or reflected
sunlight, even through windows, should also be
avoided. Uncovered hose should not be stored
under fluorescent or mercury lamps which
generate light waves harmful to rubber.
Storage areas should be relatively cool and dark,
and free of dampness and mildew. Items should be
stored on a first-in, first-out basis, since even under
the best of conditions, an unusually long shelf life
could deteriorate certain rubber products.
