Aerial lift safety Environmental & Safety Services 2009

INTRODUCTION : 

INTRODUCTION There are a wide variety of Aerial Lifts used in today’s workplace. Each device will have unique characteristics which you must understand to operate safely. Serious accidents and fatalities can occur when safe work practices are not followed. This includes falls from the platform, overturning the vehicle, and contacting energized lines in a non-insulated basket. Government regulations require that all Aerial Lift operators are properly trained. The information provided in this program provides you with necessary training to prevent accidents when working with Aerial Lifts. By understanding the principles in this program and respecting the potential hazards, you can safely work on aerial lift platforms and baskets. 2

PRE-OPERATIONAL INSPECTION : 

PRE-OPERATIONAL INSPECTION Before each shift, a pre-operational inspection is necessary to prevent accidents caused by equipment malfunction. Park the vehicle on a level surface and do a walk around check that includes the following: The air pressure of the tires, look for excessive wear. The hydraulic fuel level and pressure. The fuel, oil, and coolant levels. The battery level and connections, on electrical units make sure it is properly charged. 4

PRE-OPERATIONAL INSPECTION Cont... : 

PRE-OPERATIONAL INSPECTION Cont... Make sure pivot pins are secure. Check hoses for worn areas. Check for cracks or deviations in welded parts. The safety limit switch should work freely. Check the condition of outriggers and stabilizers. The security of the guard rail system on the platform. 5

PRE-OPERATIONAL INSPECTION Cont... : 

PRE-OPERATIONAL INSPECTION Cont... Raise and lower each boom system separately, listen for any unusual noises, vibrations, or uneven operations. Check for hydraulic leaks. Check both ground and platform control functions. CONSULT THE OWNERS MANUAL FOR PRE-OPERATION INSPECTIONS SPECIFIC TO THE UNIT. Government regulations require that the owner’s manual be stored on the unit in a designated compartment at all times. NEVER MAKE ALTERATIONS ON THE VEHICLE WITHOUT THE MANUFACTURER’S CONSENT. 6

SITE EVALUATION : 

SITE EVALUATION All ground and aerial hazards must be eliminated before operating an Aerial Lift at the site. Cordon off holes, drop-offs, bumps, or weak ground surface. Note where inclines or ramps exist. Determine proper positioning for the unit. Make sure surface is level. If outriggers are needed, make sure the ground is able to handle the force. 7

ON THE MOVE : 

ON THE MOVE Self-Propelled Aerial Platforms To move safely from work site to work site, you must avoid all ground hazards and travel with the boom (or platform) only slightly raised, in a position that gives you the best visibility. Traveling with the boom raised high exposes yourself to overhead hazards and could make the unit unstable. Use caution, never travel with the boom raised around corners. Avoid all bumps, holes, and drop-offs. Travel only at speeds that conditions allow. Always wear the proper fall protection. 8

ON THE MOVE Cont... : 

ON THE MOVE Cont... Vehicle-Mounted Booms The basket must be lowered to the cradled position before moving. Never move the truck with a co-worker elevated, or in the basket. 9

MINIMUM SAFE APPROACH DISTANCES : 

MINIMUM SAFE APPROACH DISTANCES Most Self-Propelled Aerial Lifts do not have insulated platforms. Caution must be used when working around overhead electrical lines and energized parts. The following chart shows government guidelines for Minimum Safe Approach Distance to energized lines for non-authorized workers. 10

Minimum Clearance Distances for Equipment : 

Minimum Clearance Distances for Equipment It is important to note that in most cases the unit must be parked further away than the Minimum Safe Approach Distance. This will allow for sway of the machine and electrical lines, or the possibility of reaching into that zone with a conductive tool.

Slide 12: 

Voltage Range Minimum Safe Approach Distance MIOSHA Requires (Phase to Phase) Feet Meters 0 to 300V Avoid Contact Minimum 10’ 300V to 50KV 10 3.05 Minimum 10’ Over 50kV to 200kV 15 4.60 200kV - 16’8” Over 200kV to 350kV 20 6.10 350kV - 21’8” Over 350kV to 500kV 25 7.62 500kV - 26’8” Over 500kV to 750kV 35 10.67 750kV - 35’ Over 750kV to 1000kV 45 13.72 1000kV - 46’8” It is important to note that in most cases the unit must be parked further away than the Minimum Safe Approach Distance. This will allow for sway of the machine and electrical lines, or the possibility of reaching into that zone with a conductive tool. 12

Slide 13: 

Unless verified, assume all electrical parts are energized. If work must be done within the minimum safe approach distance, the owner of the lines must be contacted and the energy isolated before the minimum safe approach distances are encroached. 13

QUALIFIED PERSONNEL AND INSULATED AERIAL BASKETS : 

QUALIFIED PERSONNEL AND INSULATED AERIAL BASKETS Only qualified personnel are allowed to approach within the minimum safe approach distance of an energized line. When working near energized parts from an insulated platform: Cordon off the area to prevent others from contacting the vehicle. If an insulated basket comes in contact with an energized part it could energize the vehicle. Always wear the proper personal protective equipment. Rubber gloves, sleeves, and safety hard hats must be rated for the nominal voltage of the energized part. 14

QUALIFIED PERSONNEL AND INSULATED AERIAL BASKETS Cont... : 

QUALIFIED PERSONNEL AND INSULATED AERIAL BASKETS Cont... Do not work on the same energized line or equipment of different phase of polarities simultaneously with co-workers. Keep the basket under or to the side of conductors. Avoid raising the basket directly above primary conductors. Never alter the insulated basket. 15

STABILIZING THE VEHICLE : 

STABILIZING THE VEHICLE Overturning a unit will lead to serious injury. Improper positioning, improper use of the outriggers, or overloading the boom could cause the unit to overturn. Maneuver the vehicle onto a level surface whenever possible. Never lift the boom if the unit is unstable. Cordon off the area to prevent accidents with other vehicles. 16

STABILIZING THE VEHICLE Cont... : 

STABILIZING THE VEHICLE Cont... Make sure the area is cleared of all personnel before extending outriggers. A block that is three times the size of the outrigger float should be used to dispense the pressure over a larger surface area. Never use the unit as a crane. The dead-man’s switch is designed to prevent unintended movement from occurring. NEVER BLOCK THE DEAD-MAN’S SWITCH. 17

ELEVATED SAFETY : 

ELEVATED SAFETY Falls are second only to automobile accidents as the leading cause for occupational deaths. Government regulations require that the proper fall protection be worn when working on Aerial Platforms. With the use of good judgment and safe work practices you can prevent falls from occurring. Never belt off to an adjacent structure. What if the platform was unintentionally moved? Never climb a raised platform. 18

ELEVATED SAFETY Cont... : 

ELEVATED SAFETY Cont... Good housekeeping is necessary to prevent becoming entangled in ropes, electrical cords, hoses or tools. Keep the work surface clear of all obstructions Tie off cords or tape them down. Tools should be hung or put into a belt whenever possible. 19

EMERGENCY SITUATIONS : 

EMERGENCY SITUATIONS Self-Propelled aerial lift platforms are equipped with an emergency system at ground control, if, for any reason, the platform controls are inoperative, the Emergency Pump System must be used. The operator should never climb out of the boom. The person operating the emergency boom must use caution to avoid being trapped by the descending boom sections. NEVER TOUCH THE VEHICLE IF IT IS IN CONTACT WITH ENERGIZED PARTS. Contact the proper personnel immediately and have the line shut off before rescue procedures begin. 20

SUMMARY : 

SUMMARY Aerial Lifts are an important tool at your facility. They make hard to reach jobs accessible, while reducing the hazards and labor associated with ladders and platforms. Serious accidents can occur if safe work procedures are not followed. Keep the unit in good working order with regularly scheduled maintenance, perform a pre-operation inspection before each shift to detect possible problems. Never operate a unit that does not pass inspection. 21

SUMMARY : 

SUMMARY Eliminate all hazards both to and at the site before operating. Travel with caution and never elevate the boom when the unit is unstable. Always maintain firm footing and never use the unit for something it was not designed for. As a trained operator, you must respect the potential hazards and keep safety as your top priority.
