1. SITE AERIAL/SCISSOR LIFT
TRAINING

2. SITE AERIAL LIFT TRAINING
 CPWR reports that about 26
workers die from aerial lift
related accident each year,
which is about 2-3% of all
construction deaths.
 They also report that 70% of the
deaths involve boom-supported
lifts and 25% involve scissor
lifts.
 Electrocutions, falls, and tip-
overs are the 3 main causes of
aerial lift deaths.

3. Other Causes of Injuries
■ Being caught in/between the lift
bucket or guardrail and hard
material such as steel beams or
joists.
■ Being struck by objects that
have fallen.
■ Workers can be tossed from a
bucket if the boom or bucket is
struck by other equipment.

4. Objectives
We’ll be covering:
 OSHA regulations
 Pre-shift and Job-Site Inspections
 The Different Types of Aerial Lifts
 Platform Stability and Capacity
 Written Test Portion
 Hands –On Demonstration (Time and Weather Permitting)

5. OSHA Regulations
■ OSHA regulations are rules
that are mandated by law.
■ Like all laws, regulations
must be followed at all times
without exception, through
“compliance”.
■ If they are not followed,
serious consequences such
as hefty fines, lawsuits,
injuries, or death can occur.
OSHA Website

6. Industrial Standards
■ OSHA refers to the following industry standards in
relation to aerial lifts:
– The American National Standards Institute (ANSI)
– The Scaffold Industry Association (SIA)
Applicable Standards are:
■ ANSI/SIA- A92.5: Boom Supported Elevating Work Platforms
■ ANSI/SIA- A92.6: Self Propelled Elevating Work Platforms

7. Company/Employer Policy
■ A company policy is a code of rules usually put in a
handbook that defines what the company does and does
not tolerate, and how it enforces this code.
■ The company policy is very company specific, as it
provides further mandates that laws/federal regulations do
not.
■ A company policy often aligns itself with federal laws and
regulations, and is not able to cancel them out. A
compliance officer or manager should regularly ensure
that both federally mandated laws, and the company
policy is adhered to.

8. Manufacturer’s Instructions
■ OSHA standards typically refers to
the “operating manual” that
accompanies equipment,
materials, etc.
■ This is booklet contains specific
instructions on how to use that
item according to it’s intended
design.
■ It’s important that an operator
becomes familiar with both the
location of the manual (in an
easily accessible location) and the
contents of the manual itself.

13. Two Basic Types of Aerial Lifts
1) Self-Propelled:
 Aerial platforms (Scissor/Vertical lift)
 Platform cannot be positioned
completely beyond the base
 Typically used to position personnel,
tools and materials at work locations
2) Boom Supported:
 A boom supported aerial work
platform (Boomlift/JLG)
 Platform can be positioned
completely beyond the base
 Used to position personnel, tools
and materials at work locations.

14. Types of Boomlifts
Articulated Boomlifts:
 More widely used in modern times.
 Easily handle narrow aisles
 Can get up and over obstacles to
place personnel and their tools in
areas a straight mast can’t.
 Capacities form 500 to 1000 lbs.
 Powered as the straight mast types
by gas, gas/propane, diesel or
electric DC motors.
Straight Mast Booms:
 Most Boomlifts manufactured to date are
of the straight mast type.
 They’re suitable for working outdoors and
operating over rough ground.
 Narrow width units are best when working
in confined areas (ex. congested
warehouses, performing refinery pipeline
maintenance, etc.)
 Load capacity of 500-1000 lbs. and can be
powered by Gas, Propane, gas/propane
or diesel and sometimes electric motors.

An area of concern is the lift’s
wheelbase. It may be too wide for some
areas, so it may be necessary to take
measurements.
Scissor lifts typically come in 30” to 10’
wheelbase widths, and have both a

23. Types of Inspections
■ OSHA regulations require a few different types of
inspections when operating aerial lifts. They include:
– Frequent inspections
– Annual inspections
– Pre-start/ Pre-Use inspections
– Workplace inspections

24. Frequent and Annual Inspections
Annual
– Must occur annually by a person who is qualified as a mechanic on the
specific make and model of the lift.
– Significantly more in depth than a frequent inspection, and involves
testing critical components required by the manufacturer.
Frequent:
– In service for 3 months or 150 operating hours.
– Out of service for a period longer than 3 months.
– Purchased used, unless documentation of current inspections is
available.
– Must be performed by a person who is qualified as a mechanic on the
specific make and model of the lift.

25. Pre-Start / Pre-Use
Pre-start inspection of the lift must be done at the following
times:
– At the start of the shift
– Before use each day
Check for:
– Obvious visible damage
– Loose, missing, broken, or damaged parts
– Proper operation of all powered systems
– Leaks of any kind
– The manufacturer’s operating and maintenance manuals.
– The appropriate ANSI/SIA manual of Responsibilities
– Other items related to the integrity and safe operation of the
unit
Remember: Most
users are not
mechanics so they
must look for the
obvious

26. Inspecting Internal Components
■ Check pans for signs of Leaks
Hydraulic System Fuel Tank

27. Remember!
Prior to conducting a pre-use inspection,
make sure that the aerial lift is in an area
that is safe and appropriate.
If you discover anything during your
inspection that presents a significant risk of
injury, lock out and tag the unit as
unusable and immediately report your
findings to a supervisor or employee
representative.

28. Workplace Inspection
In addition to the pre-use inspection, you must also conduct a workplace
inspection. This means you inspect the area in which you intend to use the
equipment.
Inspect your area for:
 Drop-offs or holes
 Bumps and floor/ground obstructions
 Debris
 Overhead obstructions/energized power lines
 Hazardous locations
 Ground surfaces and support conditions
 Pedestrian/vehicle traffic
 Wind and weather conditions

29. The Base Section
The base section has the Drive Wheels
& Axle, Counterweight System, Steering
Wheel & Axle, Lower Controls, Tires &
Wheels, Turret Turntable, and turntable
lock-pin.

30. Drive Wheels & Axle
In order to have the best possible
traction when traveling over rough
ground, the platform of the boomlift
should be over the drive wheels and
axle.
This is because of the leverage
forced on the drive wheels by the
platform, plus the weight of the
worker and their tools and materials.
Steering Wheels
Drive Wheels For
maximum
traction
keep the
platform

31. Tires
Tires are available with different types of tread design and fill
agent.
 Traction Tread- characterized by a deep, directional tread for
rough terrain applications.
 Farm Implement- designed to ride on top of typical surfaces
found in the agricultural industry.
 Slab application/Solid- Designed for use on hard, flat
surfaces available in white/grey “non-marking” varieties

32. Fill Agents
■ Pneumatic- Filled with compressed air, must be maintained at a specific
pressure (recommended by the manufacturer).
■ Nitrogen- Doesn’t react with other elements so it won’t contribute to
oxidation (rusting) or support combustion (fire). They last longer and
maintain pressure longer than regular pneumatics.
■ Liquid-filled- Referred to as ballast or hydrofill, they’re filled with a liquid
compound (calcium chloride and water). This compound weighs
approximately 3.5x more than water and will not freeze in low temps.
■ Foam-Filled- Tires filled with a foamy, liquid compound that solidifies over
1-3 days, and is available in various weights and densities.
■ Urethane Filled- Other solid tires are filled with urethane, a derivative of
rubber. Both foam and Urethane filled tires don’t go flat when punctured; a
significant design advantage over air and liquid-filled types.
Calcium chloride is a hazardous material that
presents a bodily and environmental hazards.
Handling tires w/ CaCL must be conducted by
trained and qualified personnel.

33. Do’s And Don’ts Of Boomlift
And Scissorlift Operation
Do:
- Limit travel speed according to conditions of ground surface, congestion of worksite,
visibility, slope, grade, location of personnel, or any other factors causing hazards of
collision or injury to personnel.
-Maintain a clear view of the path of travel when elevated.
-Maintain a safe distance from obstacles, debris, drop-offs, holes, depressions,
ramps, and other possible hazards when elevated.
-Shut down the boomlift/Scissorlift if any malfunction is suspected and report the
malfunction immediately after lockout of the boomlift.
Don’t:
- Use planks, ladders or other devices on the boomlift platform in order to achieve any
additional height or reach.
- Stunt drive or horseplay.

34. Scissorlift Operating Procedure
Never travel on any
grade while the
platform is elevated.

35. Energized Power Lines and Parts
The Boomlift/Scissorlift operator
MUST ensure that the minimum
safe approach distances
(M.S.A.D.) to energized power
lines and parts is maintained
during entire.
Operators MUST assume all
electrical parts and wiring are
ENERGIZED unless proven
otherwise.
VOLTAGE RANGE MINIMUM SAFE

Over 500KV- 750KV 35 10.67
Over 750KV- 1000KV 45 13.72

36. Turret Turntable
The turret turntable is the
structural platform that supports
the elevating and platform
sections, and is connected to the
base section by it’s rotary
manifold and gears.

37. Elevating Section
 The Lift Cylinders
 The Mast Section usually
contains two or three
different sections that fit
one into the other.

38. Counterweight System
The counterweight system includes: the counterweight itself, the Turntable
assembly for boomlift (which includes components of the motor and hydraulic
systems), the structural components which make up the base frame, plus tires
and wheels.

39. Lower (Emergency) Controls
• Should be readily accessible from the ground.
• Are usually located on the turntable (boomlift).
• Both the position and identity of the controls should be clearly marked on the
boomlift/scissorlift itself for easy locatiing and use.
• The Lower Controls can override the upper controls.
• As awlasy, only trained and authorized should operate the Boom/Scissorlift
controls.

40. Important Notes
Lower controls should only be used:
1. During pre-shift checkout functions of lower controls.
2. When overriding the upper controls to gain access to the
operator in the event of an emergency.
3. Only after permission has been given to operate a
boomlift function by the operator.
4. By a qualified mechanic during repairs or performing
maintenance.

41. Platform Boomlift
Guardrails must be able to withstand 300lbs of weight applied in a downward position;
mid-rail should be mid way between platform and top rail.

42. Platform Safety
 Always know the weight of the load and
make sure it doesn’t exceed that
manufacturer's load capacity.
 Always stay within the operating limits.
 Foot controls for boom lifts must operate
freely and should not stick or bind.

43. Stability and Capacity
Characteristics
Stability and capacity capabilities and limitations of the aerial
lift are easy to maintain when you understand how the factors
involved affect it’s operation.
These factors are:
– Leverage
– Center of Gravity
– Motion
– Unit Configuration

47. Center of Gravity
 The “Center of Gravity” is the point at
which all forces of gravity are equal on
an object.
 With aerial lifts, the CG of the unit,
and the CG of the load placed in the
platform, create a combined center of
gravity.
 The point where the combined center
of gravity is located is constantly
shifting as the platform is operating in
or out, up or down, forwards or
backwards, and rotating left or rotating
right.

48. Motion
■ When the aerial lift is in motion, certain dynamic
forces act on the CG as the lift’s weight distribution
shifts.
■ Think of the CG as representing the weight of the
unit; it must remain within the area between the
wheels in order for the unit to remain upright.
■ If the CG is outside this defined area, the machine
will tip over.

49. What affects the CG?
Actions such as:
– Stopping
– Turning
– Moving Forward
– Reversing
Remember: The CG directly affects stability. The more sudden,
severe or abrupt the action is, the more adverse an effect it
will have on stability.

50. Slope Warning System
Slope Warning System activates an audible and/or visual alarm
whenever the base is off level over five degrees or a lesser amount
specified by the manufacturer.

51. Scissor lift Extension Deck
Deck Extension
 The deck extension provides the
operator greater reach capability,
but the operator should be aware
that it has a maximum capacity.
 If the scissor lift is fully extended,
and the operator still cannot
reach the work location, it would
be then be necessary to use a lift
with greater reach or a Boom lift.
 No planks or ladders should ever
be used in the platform.

52. Load Charts

53. Data Plate

54. Sideslopes & Grade
 Boom/Scissor lifts are intended to be used on a flat and
level surface.
 When traveling over a long distance, it is advisable to lock
the turntable if the unit has one.
 Keep the boom mast retracted, and keep the operator
platform at or below a horizontal position to the ground.
 The boom/scissor lift should not be driven on grades or
side-slopes exceeding what’s specified on caution
placards or stated in Operations Manual.

55. Different Fuels, Propane (LPG) and
Batteries
 Fuels most often used to power boom lifts are
gasoline and diesel.
 Propane-fueled and Battery-operated lifts are
becoming increasingly more popular.
 What advantages do propane and battery power
offer that gasoline and diesel do not?

56. Safety Practices When
Refueling
 Make sure the engine is off prior to filling the fuel tank.
 When fueling the lift, never smoke or be anywhere near an
open flame.
 Clean up fuel spills immediately and report it to Safety or
an immediate supervisor.
 Never mistakenly put fuel into the hydraulic tank.

57. Propane
 Propane is a gas stored under pressure in a liquid form,
and the pressure works to an advantage.
 For instance, a fuel pump is not necessary moving
propane to the engine.
 If the fuel system develops a leak, a flame or spark could
ignite a leak. In which case, a fire or an explosion could
result.

58. Changing/Charging/Adding
a Fuel Source
■ Handling of certain fuels may require additional specific training
and certification.
■ Safe fueling basically comes to observing three things:
– 1. Ensure the unit is shutdown and secure.
– 2. Ensure you’re wearing the required PPE.
– 3. Ensure you’re familiar with the manufacturer’s instructions on
safe fueling procedures, including the type and grade of the fuel
used, and the location of the fuel filler spout.
Remember: Working with batteries requires a higher level of PPE.

59. Battery Chemicals
Batteries contain:
■ Lead
 Antimony
 Lead Peroxide
 Sulfuric Acid
Hydrogen vapors are produced during the charging process. Because of this,
there must be adequate ventilation in the battery charging area.
If an operator comes into contact with battery acid, they must rinse the area
immediately and report to the clinic.
ALWAYS REFER TO THE OPERATION & MAINTENANCE MANUAL TO VERIFY THE
LOCATION OF THE CHARGER UNIT AND THE PROPER RECHARGING
PROCEDURES FOR YOUR AERIAL LIFT WORK PLATFORM

60. Parking and Shutdown
■ Park the lift on a firm and level ground.
■ Retract and lower all boom/platform sections.
■ Turn off the main power source (engine or battery).
■ Always remove the key(s).
■ Ensure that all access panels/filler caps are locked.
■ If the lift is on a grade, remember to chock the wheels.
■ Turn main power source selector to “Off” position and lock.
