The aerial platform is not electrically insulated. Death or serious injury will result from contact with, or inadequate clearance from, an energized conductor.
Do not go closer than the minimum safe approach distance as defined by the Minimum Safe Approach Distance section in Chapter 3–Safety.
Regard all conductors as energized.
Allow for electrical wire sag and aerial platform sway.
If the platform, scissors structure, or any part of the aerial platform contacts a high-voltage electrical conductor, the entire machine can become electrically charged.
If that happens, remain on the machine and do not contact any other structure or object. This includes the ground, adjacent buildings, poles, and any other objects that are not part of the aerial platform.
Such contact could make your body a conductor to the other object, creating an electrical shock hazard resulting in death or serious injury.
If an aerial platform is in contact with an energized conductor the platform operator must warn ground personnel in the vicinity to stay away. Their bodies can conduct electricity creating an electrical shock hazard resulting in death or serious injury.
Do not approach or leave the aerial platform until the electricity has been turned off.
Do not attempt to operate the lower controls when the platform, scissors structure, or any part of the aerial platform is in contact with a high-voltage electrical conductor or if there is an immediate danger of such contact.
Personnel on or near an aerial platform must be continuously aware of electrical hazards, recognizing that death or serious injury can result from contact with an energized conductor.

Chapter 3 – Safety
Prestart Inspection
Perform a prestart inspection before each shift as described in Chapter 8. Do not use the aerial platform on the job unless you are trained and authorized to do so.
Work Place Inspection and Practices
Do not use the aerial platform as a ground connection when welding.
yy The welding ground clamp must be attached to the same structure that is being welded.
yy Electrical current flow can be very intense, causing serious internal damage to some components.
Inspect the area before and during aerial platform use. The following are some potential hazards that may be in the work place:
yy Debris
yy Slopes
yy Drop-offs or holes
yy Bumps and floor obstructions yy Overhead obstructions
yy Unauthorized persons yy High voltage conductors
yy Wind and weather conditions
yy Inadequate surface and support to withstand load forces applied by the aerial platform in all operating configurations
Before using the aerial platform in any hazardous (classified) location, make certain it is approved and of the type required by ANSI/NFPA 505 for use in that particular location.
Knowandunderstandthejobsitetraffic-flowpatternsand obey the flagmen, road signs and signals.
While operating the aerial platform, a good safety practice is to have qualified personnel in the immediate work area to:
yy Help in case of an emergency
yy Operate emergency controls as required
yy Watch for loss of control by platform operator
yy Warn the operator of any obstructions or hazards that may not be obvious to them
yy Watch for soft terrain, sloping surfaces, drop-offs, etc. where stability could be jeopardized
yy Watch for bystanders and never allow anyone to be under, or to reach through the scissors structure while operating the aerial platform
Danger
Pinchpointsmayexistbetweenmovingcomponents. Death or serious injury will result from becoming trapped between components, buildings, structures, or other obstacles. Make sure there is sufficient clearance around the machine before moving the chassis or platform. Allow sufficient room and time
to stop movement to avoid contact with structures or other hazards.
Always look in the direction of movement.
yy Drive with care and at speeds compatible with the work place conditions.
yy Use caution when driving over rough ground, on slopes and when turning.
yy Do not engage in any form of horseplay or permit riders any place other than in the platform.
Secure all accessories, containers, tools and other materials in the platform to prevent them from accidentally falling or being kicked off the platform. Remove all objects that do not belong in or on the aerial platform.
Never steady the platform by positioning it against another platform.
Warning
The potential for an accident increases when operating an aerial platform that is damaged or malfunctioning. Death or serious injury could result from such accidents. Do not operate the aerial platform if it is damaged or malfunctioning.
Do not operate the aerial platform if it is damaged or not functioning properly. Qualified maintenance personnel must correct the problem before putting the aerial platform back into service.
Operation
Use three points of support when entering or exiting the platform. For example, use two hands and one foot when climbing into the platform.
Make sure the area below the platform is free of personnel before lowering.
Keep both feet positioned firmly on the platform floor.
Do not dismount while the aerial platform is in motion or jump off the platform.
Properly stow the aerial platform and secure it against unauthorized operation at the end of each work day, before transporting, or if it is left unattended.
Tip-Over and Falling Hazards
Operate the aerial platform only on a firm, flat, level surface capable of withstanding all load forces imposed by the aerial platform in all operating conditions. Refer to the

Danger
Theaerialplatformcantipoverifitbecomesunstable.
Death or serious injury will result from a tip-over accident. Do not drive or position the aerial platform for elevated use near any drop-off, hole, slope, soft or uneven ground, or other tip-over hazard. Do not raise the platform outdoors.
Do not operate the aerial platform within 4′(1.2 m) of any drop-off or hole.
Do not raise the platform in winds. Do not add anything to the aerial platform that will increase the wind loading such as billboards, banners, flags, etc.
Never operate the aerial platform without all parts of the guardrail system in place and the safety gate closed. Make sure that all protective guards, cowlings, and doors are securely fastened.
Do not exceed the platform capacity nor the platformextension capacity as indicated on the platform rating placard on the platform. Do not carry loads that extend beyond the platform guardrails without prior written consent from Snorkel.
Do not operate the aerial platform from trucks, trailers, railwaycars,floatingvessels,scaffolds,orsimilarequipment unless the application is approved in writing by Snorkel.
Do not use the aerial platform as a crane, hoist, jack or for any purpose other than to position personnel, tools, and materials.
Do not climb on the guardrails or use ladders, planks, or other devices to extend or increase the work position from the platform.
Take care to prevent rope, electrical cords, and hoses, etc., from becoming caught in or on the aerial platform.
yy If the platform or scissors structure becomes caught on an adjacent structure or other obstacle and is prevented from normal motion, reverse the control to free the platform.
yy If control reversal does not free the platform, evacuate the platform before attempting to free it.
It is best not to transfer from the platform to another structure or from the structure to the platform, unless that is the safest way to do the job. Judge each situation separately taking the work environment into account. If it is necessary to transfer from the platform to another structure the following guidelines apply:
1.If you are using a fall restraint, transfer your anchorage from one structure to the other before stepping across.
2.Remember that you might be transferring to a structure where personal fall arrest is required.
3.Use the platform entrance, do not climb over or through the guardrails.
Electrical System
Charge the batteries in a well-ventilated area free of flame, sparks, or other hazards that might cause fire or explosion.
Do not operate any of the aerial platform functions while the battery charger is plugged in.
Warning
Batteries give off hydrogen and oxygen that can combine explosively. Death or serious injury could result from a chemical explosion. Do not smoke or permit open flames or sparks when checking the batteries.
Battery acid can damage the skin and eyes. Serious infection or reaction could result if medical treatment is not given immediately. Wear face and eye protection when working near the batteries.
yy Batteries contain sulfuric acid that can damage your eyes or skin on contact.
yy Wear a face shield, rubber gloves, and protective clothing when working around batteries.
yy Ifacidcontactsyoureyes,flushimmediatelywithclear
water and get medical attention.
yy If acid contacts your skin, wash off immediately with clear water.
Hydraulic System
The hydraulic system contains hoses with hydraulic fluid under pressure.
Danger
Hydraulic fluid escaping under pressure can have enough force to inject fluid into the flesh. Serious infection or reaction will result if medical treatment is not given immediately. In case of injury by escaping hydraulic fluid, seek medical attention at once.
Do not place your hand or any part of your body in front of escaping hydraulic fluid. Use a piece of cardboard or wood to search for hydraulic leaks.
Placards and Decals
The aerial platform is equipped with placards and decals that provide instruction for operation and accident prevention. Do not operate the aerial platform if any placards or decals are missing, damaged, or illegible.

Chapter 4 – Safety Devices
This aerial work platform is manufactured with safety devices, placards, and decals to reduce the likelihood of an accident.
yy For the safety of all personnel, do not disable, modify, or ignore any safety device.
yy Safety devices are included in the daily prestart inspection.
Warning
The potential for an accident increases when safety devices do not function properly. Death or serious injury could result from such accidents. Do not alter, disable, or override any safety device.
If any safety devices are defective, remove the aerial platformfromserviceuntilqualifiedmaintenancepersonnel can make repairs.
Emergency Stop Controls
There is an emergency stop control at the lower and upper controls. Both the lower and upper control emergency stop buttons must be on to operate the machine.
At the lower controls, the emergency stop is a two-posi- tion red push button (refer to Figure 4.1).
