If the machine has to be parked on an incline, lock the
wheels.
Avoid fire hazards and have fire protection equipment
ready in the work area. Do not use an open flame to check
the fluid level, especially of battery electrolytes. Do not use
open pans of fuel or flammable cleaning fluids to clean
parts.
Properly ventilate the work area, discharge exhaust gases
and keep the workshop clean and dry.
The brakes, steering mechanisms, control mechanisms,
warning devices, lighting, controls, protection and safety
devices, stops for the articulated axles and the frame parts
must be checked carefully and regularly and kept in a safe
operating condition.
FIRE SAFETY STANDARD
Devices that are not in a safe operating state must be tak-
en out of service.
Repairs may not be made in Class I, Class II, and Class III
locations.
Repairs to the electrical system of battery-operated floor
cleaners may only be made after the battery has been dis-
connected.
Operating temperature.
If it is determined that any part of
a powered floor cleaner is above its normal operating tem-
perature and poses a hazard, the vehicle should be taken
out of service and not restarted until the cause of such
overheating has been eliminated.
Fire protection.
The device must be kept in a clean con-
dition and reasonably free of lint, excess oil and grease.
Non-flammable agents are preferred for cleaning the de-
vice. Flammable liquids [those with flash points at or above
100 °F (37.8 °C)] are not permitted. Precautions regarding
toxicity, ventilation and fire hazard must be appropriate for
the agent or solvent used.
Visibility of the type plate.
The type designations of the
device stated on the type plate and the type markings must
not be painted over so that their identification information
is covered.
Changing and charging batteries.
This section applies
to batteries used in electric trucks. The two types of batter-
ies are generally lead and nickel-iron batteries. They con-
tain corrosive chemical solutions, either acidic or alkaline,
and therefore pose a chemical hazard. While charging,
they emit hydrogen and oxygen, which are explosive in
certain concentrations. Battery charging systems must be
located in designated areas; these areas must be kept free
of combustible foreign matter.
Facilities must be provided for:
1 Flushing off spilled electrolyte
2 Fire protection
3 Protecting chargers from damage by trucks, and
4 Adequate ventilation to disperse the fumes from gas
batteries
If on-board chargers are used, charging must take place at
the designated locations, taking into account the electrical
requirements for the charger and the fire protection equip-
ment.
Exception: Rinsing facilities are not required if the charging
process is carried out without removing the battery from
the vehicle.
When handling acid concentrates with more than 50 per-
cent acid (over 1,400 specific gravity), an eye-wash device
must be provided.
A conveyor belt, ceiling hoist, or equivalent material han-
dling equipment should be provided for handling batteries.
Chain hoists must be equipped with load chain containers.
When using a hand winder, uncovered batteries must be
covered with a sheet of plywood or other non-conductive
material to prevent the hand chain from shorting out the
cell connections or terminals. A properly insulated spread-
er bar must be used with every ceiling hoist.
Reinstalled or new batteries must meet or exceed the bat-
tery type specified on the device. Newly inserted batteries
must be properly positioned and secured in the device.
When using acid supplied in balloons, a balloon tipper or
siphon must be provided. When concentrated sulfuric acid
is diluted into electrolyte, the acid must ALWAYS be added
to the water - not the other way around. Battery mainte-
nance personnel must wear protective clothing such as
eye protection, long sleeves and gloves.
Exception: No protective clothing is required for removing
and replacing batteries.
Electrical installations must comply with NFPA 70, national
electrical codes, and all local codes.
Trained and authorized personnel must change or charge
the batteries.
The powered floor cleaner must be correctly positioned
and the brakes must be applied before attempting to
change or recharge the batteries.
When charging batteries, the vent caps must remain in
place to prevent the electrolyte from spraying. Make sure
that the vent caps work. The battery (or compartment) cov-
er (s) must be open to dissipate heat and gas.
Smoking is prohibited in the charging area.
Precautions should be taken to prevent open flames,
sparks, or electrical arcs in battery charging areas.
Tools and other metallic objects must be kept away from
the lids of uncovered batteries.
The device must not be used in classified areas.
Safety instructions
Before using the device for the first time, read and observe
these operating instructions and the accompanying bro-
chure: Safety instructions for brush cleaning devices, No.
