6.4 Changing and Charging Storage Batteries for
Electric Personnel and Burden Carriers

6.4.1 The user shall require battery changing and

charging facilities and procedures to be in accor-
dance with ANSI/NFPA 505 or as required by local
ordinance.

6.4.2 The user shall periodically inspect facilities

and review procedures to be certain that ANSI/NFPA
505 or as required by local ordinance, are strictly
complied with, and shall familiarize carrier operators
with it.

6.4.3 Maintenance and storage areas for carriers

shall be properly ventilated to avoid fire hazards in
accordance with applicable fire codes and ordinanc-
es.

Ventilation for internal combustion engine powered

carriers shall be provided to remove flammable va-
pors (gases), fumes and other flammable materials.
Consult applicable fire codes for specific levels of
ventilation.

Ventilation for electric powered carriers shall be

provided to remove the accumulation of flammable
hydrogen gas emitted during the battery charging
process.

The amount of hydrogen gas emitted depends

upon a number of factors such as the condition of
the batteries, the output rate of the battery charger
and the amount of time the batteries are on charge.
Because of the highly volatile nature of hydrogen gas
and its propensity to accumulate in pockets, a min-
imum number of air changes per hour is required
during charging.

Consult applicable fire and safety codes for the spe-

cific ventilation levels required as well as the use of
explosion proof electrical apparatus. SAE J1718 can
be followed to check for hydrogen gas levels.

6.5 Hazardous Locations

6.5.1 The user shall determine the hazard classi-

fication of the particular atmosphere or location in
which the carrier is to be used in the accordance with
ANSI/NFPA 505.

6.5.2 The user shall permit in hazardous areas only

those carriers approved and of the type required by
ANSI/NFPA 505.

6.6 Lighting for Operating Area

The user, in accordance with his responsibility to

survey the environment and operating conditions,
shall determine if the carrier requires lights and, if so,
shall equip the carrier with appropriate lights.

6.7 Control of Noxious Gases and Fumes

When equipment powered by internal combus-

tion engines is used in enclosed areas, the atmo-
sphere shall be maintained within limits specified in
the American Conference of Governmental Indus-
trial Hygienists publication, “Threshold Limit Values
for Chemical Substances and Physical Agents in the
Workroom Environment.” This may be accomplished
by ventilation provided by the user, or the installation,
use, and proper maintenance of emission control
equipment recommended or provided by the man-
ufacturer of the equipment.

6.8 Warning Device(s)

6.8.1 The user shall make periodic inspections of

the carrier to be certain that the sound-producing
and/or visual device(s) if so equipped are maintained
in good operating condition.

6.8.2 The user shall determine if operating con-

ditions require the carrier to be equipped with addi-
tional sound producing or visual devices or both and
be responsible for providing and maintaining such
devices, in accordance with the manufacturer’s rec-
ommendations.

6.9 Safety Interlocks

The user shall make periodic inspections of the car-

rier to be certain that the safety interlock system, if so
equipped, is operating properly.
