General park fire safety considerations.
(1)
Access to mobile homes for fire protection services.

permit fire apparatus to approach within 50 feet of the mobile home.
(2)
Clearance from mobile homes to other structures. Mobile
homes should not be located closer than 10 feet from any other mobile home
or permanent building within or adjacent to the mobile home park. Mobile home
accessory buildings should not be closer than five feet from an adjacent mobile
home lot line.
(3)
Use of fire protection equipment. The mobile home park
operator should instruct his staff in the use of the fire protection equipment
available in the park and define their specific duties in the event of fire.
Tenants should be instructed in applicable fire prevention and fire protection
rules.
(4)
Outside hazards. Care should be taken to maintain the
park area free of dry brush, leaves and weeds which might communicate fires
between mobile homes and other buildings in the park.
B.
Fire detection and alarm services.
(1)
Detection systems in buildings. Fire detection equipment
installed in mobile homes should meet the requirements of Standard for Household
Fire Warning Systems (NFPA No. 74-1967) and those installed in other buildings
open to the public should be installed at least in accordance with NFPA Standard
on Local Protective Signaling Systems (NFPA No. 72A-1967). Note: See NFPA
Standards No. 71, 72B, 72C or 72D for other suitable types of fire protective
signaling systems.
(2)
Public fire alarm services. Street fire alarm services
for the park, if provided, should be in accordance with the NFPA Standard
for Municipal Fire Alarm Systems (NFPA No. 73-1967). Where such services are
not available, alarm procedures should be posted in each mobile home and in
each public building in the park as approved by the local Fire Department.
C.
Water supplies for fire protection.
(1)
Quantities. Water supplies for Fire Department operations
shall be provided to permit the effective operation of a minimum of 500 gallons
per minute with 20 pounds residual.
(2)
Supply criteria. It is desirable to have a public water
supply system for fire protection with hydrants located within 500 feet of
all mobile home lots. A private hydrant system complying with the NFPA Standard
for Outside Protection (NFPA No. 24) may be substituted where public fire
services are not available. Alternate water supply arrangements which may
be used if acceptable to the authority having jurisdiction are:
(a)
An approved reservoir or water supply source of not less
than 3,000 gallons suitably arranged for Fire Department drafting and so located
that each mobile home lot is within 300 feet of a supply point; or
(b)
Fire Department apparatus equipped with a water tank
and constructed in accordance with the NFPA Standard for Automotive Fire Apparatus
(NFPA No. 19-1971) which can be expected to be provided by the local Fire
Department and which can be driven to the park in time, elements considered
satisfactory to the authority having jurisdiction.
(3)
Hydrants. Hydrant hose coupling threads should be national
standard threads (See NFPA Standard for Screw Threads and Gaskets for Fire
Hose Couplings, NFPA No. 194-1968) or should conform to those used by the
local Fire Department.
D.
Mobile home park portable fire-fighting facilities.
(1)
Permanent buildings. Permanent buildings should be provided
with portable fire extinguishers in accordance with the provision of the NFPA
Standard for Portable Fire Extinguishers (NFPA No. 10-1970; ANSI Z112.1-1970).
(2)
Mobile homes. It is recommended that each mobile home
owner be encouraged to provide for his own protection an approved* portable
fire extinguisher suitable for handling incipient fires in the home. An approved
extinguisher labeled as suitable for Class A, B and C fires (multipurpose
dry chemical type) is recommended; alternatively, a ten-pound approved* extinguisher
having a label for Class B and C fires (carbon dioxide or dry chemical type)
should be provided for the kitchen area and either an approved* extinguisher
or a hose line for handling Class A fires in the balance of the mobile home.
The provision on each lot of a three-fourths-inch valved water outlet designed
for connecting a three-fourths-inch female swivel hose connection for exclusive
fire suppression use is desirable where practical (protected against freezing).
[Amended 4-9-1984 by L.L. No. 4-1984]

* NOTE: "Approved" is intended to indicate extinguishers tested and
labeled by the Underwriters' Laboratories, Inc., the Underwriters'
Laboratories of Canada (ULC) or the Factory Mutual Engineering Corporation
