1 PAGE 1 OF 10 PURPOSE: MOBILE CRANES PROCEDURE To establish a procedure that provides guidelines that constitute safe operation of mobile cranes. It is not all encompassing or intended to replace common sense and professionalism expected from qualified personnel operating this type of equipment. PROCEDURE: Scope This procedure applies to the Company and contract personnel performing crane work activities. All qualified crane operators shall always have in their possession a current driver's license and documentation of training and qualifications identifying the specific type of equipment for which they are qualified. Personnel Qualifications A. The Company Operators: Only employees qualified by training or experience shall be permitted to operate mobile cranes. B. Contract Operators: Only contract employees authorized by the contractor and trained, or known to be qualified, in the safe operation of cranes or hoisting apparatus, shall be permitted to operate such equipment. By November 8, 2014 all operators must be qualified/certified by an accredited crane operator testing organization, an audited employer program, the US military, or licensed by a government entity. General Requirements A. All new Crawler and Truck cranes used at the Company, constructed and utilized on or after August 31, 1971, shall meet the design specifications, inspection, testing, maintenance and operation as prescribed in ANSI B B. All manufacturers specifications regarding the operation of cranes including their use with attachments must be observed and all mobile cranes shall have a signaling chart posted. C. Only designated and contract qualified personnel are allowed to perform attendant, signal person, operator or other duties associated with crane work activities. Crane operators must not leave the cab while a load is still on the hook.

2 PAGE 2 OF 10 D. A carbon dioxide, dry chemical or equivalent fire extinguisher shall be kept in the cab or vicinity of the crane. Operating and maintenance personnel shall be familiar with the use and care of the fire extinguisher provided. E. When any crane is operated in an enclosed space testing shall be conducted and recorded to ensure that employees are not exposed to toxic gasses or an oxygen deficit atmosphere. F. A catastrophic crane failure could result in serious injury to either the crane operator or personnel involved in working around the crane. In order to minimize the potential for such injury, the following will be observed: 1. Only authorized personnel who have been trained in the safe use and operation of cranes will be permitted to operate the crane. 2. The crane operator shall be responsible for those operations under his direct control. Whenever there is any doubt as to safety, the crane operator shall have the authority to stop the operation, re-plan the details, consult a qualified person, and continue as safety dictates. 3. When handling loads, the crane operator shall never start machine movement unless the load is within his range of vision and he has been given the appropriate signal. A signal person must be provided if the operator s view will be obstructed at any time, if site-specific concerns require a signaler, or if the operator requests a signal person. 4. The crane operator shall respond to the signals only from the appointed signal person, but should obey an emergency stop signal at any time, no matter who gives the signal. Hand signals will be in accordance with those shown on the crane hand signals chart. 5. The qualified person directing the lift shall determine that the load is secured and properly balanced in the sling or lifting device before it is lifted, and that the lift and swing paths are clear of obstructions and personnel. 6. No external forces shall be applied to suspended loads that will result in side loading of the boom. Care shall be taken when swinging the crane so as to minimize the pendulum action of the hook and suspended load. 7. When two or more cranes are used to lift one load, one qualified person shall be responsible for the operation. The responsible person must analyze the operations and instruct all personnel involved in the proper positioning, rigging of the load and the movements to be made. 8. All safety equipment on the crane must be present and functional, including tag lines, fire extinguisher, backup beeper, and load charts and boom angle indicator. 9. All slings, cables, hooks, shackles, etc., are to be fit for use and inspected prior to the lift. 10. Barricades must be erected to identify hazard areas where equipment has the strike and injure an employee or where when an employee could be pinched or crushed against another object.

3 PAGE 3 OF 10 Loading and Unloading A. Position of the crew 1. All workers must be visible to drivers and crane operators AT ALL TIMES. 2. Never stand or work between a vehicle and a load until the supervisor signals to proceed. 3. Use hand-over-hand grip procedures when handling lines. Do not let the line slip through your grip. Keep work area clear of all personnel except those essential for performing the procedure. B. Pins 1. Use cold-roll steel pins cut to a length appropriate for the load (because they will bend, not break). 2. Helpers must be visible to drivers AT ALL TIMES, especially when removing and replacing pins. 3. Do not remove pins while other work is in progress. C. Signaling 1. Signalers must always be visible to drivers. 2. Drivers and crane operators must always obey the signaler. 3. There should be only one signaler unless a relay is required. 4. Drivers and crane operators, when using signaler or helper must not winch or move truck unless signaled. D. Hand Signals: Use correct hand signals and display them properly. There should be no doubt in the operator's mind as to what to do. Care and Handling Lines A. Slings : Check for the following: broken or kinked strands, flat spots and loose eyes. 1. Replace worn slings. 2. Always hook slings to the proper pickup points or centering points. Use proper method of attaching slings to prevent any accident. 3. Do not use chains for loading or lifting. 4. Do not drag slings on the ground. 5. Coil or hand slings properly when not in use. 6. Use separate slings for towing and loading. 7. Avoid abrasions caused by pulling across sharp edges.

4 PAGE 4 OF Know safe working loads and do not exceed. B. Snatch Blocks 1. Check for excessive wear at the pins. 2. Ensure all equipment is in good working order and of the proper size. 3. Keep hands and clothing away from moving snatch blocks. 4. Lubricate snatch block with grease when required. 5. Ensure that the loading sling is long enough so that the snatch block is picked up on the trailer before the load starts to come up. 6. Use double line procedure on heavy loads. C. Suspended Loads 1. Never stand under a suspended load.. 2. Use tag lines to control and position suspended loads. 3. When working around suspended loads, maintain a sufficient distance between yourself and the load in case a sling, winch line, etc., were to fail, causing the suspended load to fall or shift. 4. To reduce the risk of being crushed, never stand between a suspended load and a stationary object (i.e., another building). D. Cheater Pipes and Bars: Cheater pipes and cheater bars will only be used as a last alternative to break a connection or loosen a binder. When a cheater pipe or cheater bar is required, the following will be done to minimize the risk of an accident. 1. The cheater pipe will be inserted as far as possible on the wrench or chain binder handle when closing the chain binder. 2. When opening a closed chain binder, do not insert a pipe over the end of the chain binder. Use a bar to pry the handle up. 3. When using cheater pipes or bars to clamp or unclamp chain binders the individual should avoid being in the anticipated path the cheater bar would travel in the event of a kickback. 4. It is the responsibility of the individual who is unclamping the chain binder to ensure that no one is standing in the anticipated path of the binder swing, or on the opposite side of a truckload being unclamped. It is possible that the load has shifted and the binder is under enough strain to jump over the truck or that the load will roll off the truck. 5. Cheater pipes of excessive length will not be used. The maximum length of the cheater should be no longer than twice the length of the wrench or binder handle. 6. If possible, always pull on a wrench handle and adjust your stance to prevent a fall if something lets go. Pushing may result in falling into the equipment being worked on, resulting in a higher likelihood of an injury.

5 PAGE 5 OF If a piece of equipment cannot be moved to a vise to assist in providing proper leverage, a cheater is preferred over jumping on a wrench handle. E. Matting 1. It is not possible to describe completely all the safety procedures for handling matting due to variances in manufacturer s hookup design and size requirements. 2. Use four-legged sling of sufficient length. Do not use tie-down chains to lift. Never crawl or walk under suspended loads. Turn the matting over and lay it down before cleaning mud stuck to bottom. Keep matting close to the ground (12-14 inches [30-40 cm]) when swinging matting to be loaded or unloaded. Helpers working on this procedure must use tag lines. G. Tag Lines 1. Tag lines will be used to control all suspended loads. If tag lines are impractical during final positioning of the load, caution should be taken to ensure that no part of the person's body guiding the load is between the load and any stationary object. 2. Hand-held tag lines will be constructed of a non-conductive material such as 1/2-inch rope, or an I-inch nylon strap. Chains or steel cables are not acceptable. 3. Never attempt to guide a load with the tag-line wrapped around your hand or waist. 4. Never use a tag line with a knot in the end. 5. A tag line should be of sufficient length to ensure that no part of the person guiding the load is under the load at any time. 6. The person holding the tag line should never position himself between a suspended load and a stationary object. G. Power Line Safety 1. A pre-operation hazard assessment shall be conducted that identifies the work zone and the locations of all power lines in the vicinity of the work zone. The operational boundaries of the work zone are to be identified by flags and range limiting devices or the work zone is to be defined by the maximum working radius of the crane for the full 360-degree range. This assessment must determine whether any portion of the equipment could within 20 feet of a power line. 2. When practical, power lines shall be de-energized for any work where contractor employees or equipment could approach within twenty feet of the power line (i.e., the boom swing of a crane). All power lines shall be considered energized unless proper measures have been taken for de-energizing and the line is visibly grounded and remains in that condition. 3. If it is impractical to de-energize power lines then precautions must be taken to assure that no part of the crane, load line or load approaches nearer than 20 feet to lines. 4. If an approach of less than 20 feet is required it is the responsibility of the competent person on the site to verify the line s voltage with the utility operator or a registered

6 PAGE 6 OF 10 engineer and then consult CFR Table-A minimum clearance distances to determine the closest safe approach distance. 5. Never allow anyone to ride on a load to lift power lines. Call the power company. 6. If vehicle or load comes in contact with a power line, stay in the vehicle and attempt to move the vehicle away from the power line, if not hooked. 7. Never allow anyone near the truck, load and trailer body when in contact with a power line. 8. If it is necessary to leave the truck, jump as far from the vehicle as possible. Land with both feet together and hop away. Never allow your body. truck and ground to be in contact at the same time. 9. Drivers should notify the power company for escort service or assistance for any load over 17 feet, six inches (5.6m) high. Ground Man Operations Safety 1. Never stand between any vehicle and load until the vehicle comes to a complete stop, the emergency brakes are applied, and the driver signals to proceed. 2. Pay attention to the location of all vehicles.. 3. Never crawl under a vehicle or a suspended load. 4. Do not climb onto or off of a truck until it has come to a complete stop and the driver signals to proceed. Be sure of footing while climbing or working on the load and getting off of the load. Do not jump off the load. 5. While working on a load, be sure that the driver knows where you are and what you are doing. Watch for pinch points. Stand to the side of an object being moved, not in direct line of the moving object. 6. Ensure that all equipment is in good working order and is the proper size for the load. Chain the load securely. Check chains and chain binders frequently during a move. Lift Plan A detailed lift plan must be developed for all critical lifts. All calculations must be submitted to Health, Safety and Environment for review. The lift plan must, at a minimum, address the following issues: 1. Necessity for soil analysis to be performed. 2. Steps to be taken by all personnel involved with the lift in case of a plant or crane emergency. 3. The safe working load of the cranes, boom angle and radius over the path as laid out by the contractor (the Company may elect to de-rate a crane's rated safe working load for safety reasons). 4. Identify one designated person who shall be responsible for the operation and compliance with lift plan requirements. This individual shall be responsible for analyzing the operation and instruct all personnel involved in the proper positioning, rigging of the load, and the movements to be made. Decisions such as the necessity to reduce crane ratings, load position, boom location, ground support, and speed of

7 PAGE 7 OF 10 movement shall be in accordance with this determination and documented in the lift plan. 5. When two or more cranes are used to lift a load, the lift plan must also clearly show orientation of the primary lift crane, tailing crane (if required) and all potential obstructions. 6. Warning: when two or more cranes are used, the rating charts for each should be de-rated by twenty-five percent unless a load equalizing device is used. Direct communication between cranes must be maintained through the designated person responsible for the lift. Mobile Crane Inspections 1. All crawler or truck cranes in use by the Company personnel shall be in sound mechanical and operational condition. Rented equipment shall not be accepted for use until documented proof of annual (periodic) safety inspection and/or rated load tests have been provided by the crane owner. This shall be maintained on the jobsite until completion of the job. In addition, there will be a load-rating chart present in the cab and a chart showing proper hand signals for crane operation. 2. Copies of documentation of the annual (periodic) inspection and/or rated load tests of any the Company equipment of this type shall also be maintained onsite for the duration of the job. 3. All original documentation for the equipment shall be maintained in the equipment files that are located at the appropriate regional office. 4. Documentations of all procedures relevant to the operation of the crane must be available in the cab at all times. This provisions includes the manufacturer s operating manual as well as any other relevant notes or manuals. 5. Periodic or annual inspections shall be performed by competent persons to determine if defects exist in any of the following: a. Cracks, deformation or corrosion of the crane structure or boom. b. Worn, cracked or distorted parts. c. Excessive wear on brake or clutch system parts. d. Inaccuracies in load, boom angle or other indicators over their full range.. e. Improper performance of gasoline, diesel, electric or other power plants. f. Excessive wear of chain drives or sprockets. g. Malfunction of travel steering, braking and locking devices. h. Excessively worn tires. 6. Periodic or monthly inspections shall be performed on all ropes. This inspection shall be documented to show the date of the inspection, size and condition of the rope and shall be signed by an authorized person competent to recognize any deficiency. 7. In addition to the periodic or annual inspection, daily (frequent) operator inspections shall be performed by a competent person and documented. These inspections shall ensure that:

8 PAGE 8 OF 10 a. There is no malfunction of any operational control. b. There is no excessive wear of control components by lubricants or other foreign matter. c. There is no malfunction of any safety device including anti-two block, backup warning devices, boom stops, jib stops, foot pedal brake locks, crane level indicator, etc. d. No leakage or apparent damage in hydraulic or pneumatic systems. e. Crane hooks and latches are not deformed or cracked. f. Rope reeving is in compliance with manufacturer's guidelines. g. The tires of the crane (if applicable) are in sound condition h. Ground conditions meet the requirements of the manufacturer for adequate support and degree of level i. A carbon dioxide, dry chemical or equivalent fire extinguisher is either located in the cab or in the vicinity of the crane. j. All electrical apparatus is functional (i.e., head and taillights, warning systems, etc.). k. Copies of these inspections shall be maintained onsite and filed in the appropriate job file upon completion of the job. Inspection reports shall be maintained for a minimum of three months. Deficiencies discovered during either periodic or frequent inspections shall be corrected when found. Until such time as the deficiencies have been corrected, the equipment shall be tagged OUT OF SERVICE. l. Prior to returning the crane to service, all guards shall be reinstalled, safety devices reactivated, and maintenance equipment removed. m. Warning: if the equipment is found to be dangerous or unsafe or if any of the safety devices are not functioning, all persons must be prohibited from using the equipment under any circumstances until the danger is removed or the unsafe condition is repaired. Onsite Maintenance, Moving, Building and Refueling of Cranes 1. A crane preventive maintenance program based on crane manufacturer's recommendations shall be kept with the crane and dated records shall be made available to the Company upon request. 2. Before adjustments and repairs are started on the crane, the following precautions shall be taken: a. Crane should be placed where it will cause the least interference with other equipment or operations in the area. b. All controls must be in the off position and all operating features secured from inadvertent motion by brakes, pawls, or other means. c. Boom should be lowered to the ground, if possible, or otherwise secured against dropping. d. Relieve hydraulic oil pressure from all hydraulic circuits before loosening or removing hydraulic components.

9 PAGE 9 OF 10 e. After adjustments and repairs have been made, the crane shall not be returned to service until all guards have been reinstalled, trapped air removed from the hydraulic system, safety devices reactivated, and maintenance equipment removed. f. Assembly or disassembly of crane booms must not be performed in areas that may impede traffic flow. It is the contractor's responsibility to coordinate with the Company representative in locating areas that will not impede traffic and to avoid congested areas. g. All manufacturer s instructions and prohibitions must be followed when assembling or disassembling cranes or crane components and these activities shall be directed by a competent and qualified person. h. Boom sections to be stored must be cribbed safely and not in constant contact with the soil or potentially corrosive materials. i. Without exception, a registered professional engineer or the crane manufacturer must certify all modifications or repairs that may affect the capacity or safe operation of cranes. Written documentation of modifications must be kept with the crane. j. Refueling of main or auxiliary engines must be done away from ignition sources and outside of the units unless previously approved by the Company. Engines must be stopped while refueling unless provisions are provided by the crane manufacturer and approved by the Company. k. When refueling with gasoline or diesel using a portable container, it shall be a safetytype can equipped with an automatic closing cap and a flame arrester. Fuel spouts or portable funnels must be designed or used in such a manner that it will prevent fuel from contacting electrical components or any other ignition sources. Site Preparation and Pre-Lift It is the crane contractor's responsibility to help establish a safe work area for the crane. The following guidelines should be considered prior to commencing work activities. 1. Access roads are prepared and room has been considered for the passage of normal traffic and emergency vehicles. If roadways must be blocked off, the shift supervisor and safety director must be notified. 2. Adequate swing clearances (two feet minimum, when possible) must be established for the crane. 3. Ropes and barricades must be erected around the lift area to prevent personnel from standing or passing under suspended load and behind (operator blind spot) the crane. 4. Operating locations for the crane must be established and supporting surfaces are suitable to handle the expected loads. Mats may be required for conditions where the bearing pressure of the crane exceeds the ability of the soil to resist the loading. The mats must be of sufficient strength to prevent crushing, bending, or shear failure. Final position preparation must provide bearing surfaces for the crane that meet or exceed the equipment manufacturer s specifications for support and machine leveling. 5. If using on outrigger load chart, the outriggers must be fully extended. If outriggers cannot be fully extended, crane may lift per a partially extended chart. If not available for

10 PAGE 10 OF 10 particular model cranes, lift should not proceed. While on outriggers, wheels must be free of the bearing surface. 6. Competent signal persons must be provided. Signal persons must have knowledge in both the use and understanding of hand signals and radio communications. 7. No cranes shall be operated in excess of the original load ratings unless such rating changes are approved, in writing, by the crane manufacturer.
