SECTION 6. EMERGENCY PROCEDURES
6.1 GENERAL INFORMATION
This section provides information on procedures to be fol-
lowed, and systems and controls to be used in the event
an emergency situation is encountered during machine
operation. Prior to operation of the machine and periodi-
cally thereafter, the entire operating manual, including this
section, should be reviewed by all personnel whose
responsibilities include any work or contact with the
machine.
6.2 EMERGENCY CONTROLS AND THEIR
LOCATIONS
CHECK MACHINE DAILY TO MAKE SURE EMERGENCY STOP
SWITCHES ARE IN PLACE AND OPERATIONAL. AND THAT
APPLICABLE INSTRUCTIONS ARE IN PLACE AND LEGIBLE.
Platform Emergency Stop Switch
This large red button is located on the platform control
station and, when depressed, will immediately stop the
machine from the platform.
Ground Emergency Stop Switch
The ground Emergency Stop switch (RED button) is
located on the Ground Control Station beside the Power
On/OFF Key switch. When depressed, will immediately
stop the machine.
Manual Descent Valve Knob
The manual descent valve is used in the event of either a
total power failure, or if the operator in the platform cannot
lower the platform himself. The manual descent knob
(RED) is located under the base frame at the rear of the
machine. To LOWER the platform, PULL the RED knob
(valve open). To STOP lowering, RELEASE the knob
(valve closed). (The platform will be lowered, unpowered,
using gravity.)
6.3 EMERGENCY OPERATION
Use of Ground Controls.
KNOW HOW TO USE THE GROUND CONTROLS IN AN EMER-
GENCY SITUATION.
BEFORE TOUCHING ANY PART OF THE MACHINE IN AN EMER-
GENCY SITUATION, FIRST DETERMINE IF MACHINE IS IN CON-
TACT WITH OR CLOSE PROXIMITY TO AN ELECTRICALLY
CHARGED CONDUCTOR. THIS MACHINE DOES NOT PROVIDE
PROTECTION FROM CONTACT WITH OR PROXIMITY TO AN
ELECTRICALLY CHARGED CONDUCTOR. (SEE ELECTROCUTION
HAZARD, SECTION 1-3.)
Ground personnel must be thoroughly familiar with the
machine operating characteristics and the ground control
functions. Training should include operation of the
machine, review and understanding of this section and
hands-on operation of the controls in simulated emergen-
cies.
Operator Unable to Control Machine
IF THE PLATFORM OPERATOR IS PINNED, TRAPPED OR UNABLE
TO OPERATE OR CONTROL THE MACHINE, USE THE FOLLOW-
ING INSTRUCTIONS AS A GUIDELINE.
1. Operate the machine from the ground controls
ONLY with the assistance of other personnel and
equipment (cranes, overhead hoists, etc.) as may be
required to safely remove the danger or emergency
condition.
2. Only qualified personnel in the platform may use the
platform controls. [DO NOT CONTINUE OPERA-
TION IF CONTROLS DO NOT FUNCTION NOR-
MALLY].
3. Cranes, forklift trucks or other equipment which may
be available are to be used to help remove the plat-
form occupant and stabilize motion of the machine
in case machine controls are inoperable or platform
cannot be lowered with the emergency/manual
decent valve.
