SAFETY

Use Of Personal Protective Equipment

• People working in areas where there are potential electrical hazards must use, personal protective equipment that is appropriate for the specic parts of the body to be protected and for the work to be performed. Refer to
U.S. Occupational Safety & Health Administration (OSHA) Regulations (Standards - 29 CFR) Safeguards for personnel protection. - 1910.335, or applicable national, state or local regulations, for additional information.
• Personal protective equipment must be maintained in a safe, reliable condition and periodically inspected or
tested.
• Protective shields, protective barriers, or insulating materials must be used to protect each person from shock, burns, or other electrically related injuries while that person is working near exposed energized parts which
might be accidentally contacted or where dangerous electric heating or arcing might occur. When normally enclosed live parts are exposed for maintenance or repair, they must be guarded to protect unqualified persons from contact with the live parts.
• Safety signs and tags. Safety signs, safety symbols, or accident prevention tags must be used where necessary
to warn people about electrical hazards which may endanger them.

Conductive Materials And Equipment

Materials and equipment that may conduct electricity must be handled in a way that will prevent them from contacting energized power lines, exposed conductors or circuit parts.
• When handling long conductive objects (such as but not limited to truss rods, pipes, angles and ladders) in areas with energized power lines, exposed conductors or circuit parts, work practices (such as the use of
insulation, guarding, and material handling techniques) must be used to minimize the hazard.
• Portable ladders must have non-conductive side rails.
• Do not wear conductive articles of jewelry and clothing (such as but not limited to watch bands, bracelets, rings, key chains, necklaces, metalized aprons, cloth with conductive thread, or metal headgear) that could
come in contact with energized power lines, exposed conductors or circuit parts.

Fall Protection

Identify potential fall hazards and determine if fall protection equipment is appropriate for the task, before beginning the work. Pay attention to hazards associated with routine and non-routine tasks. Inspect fall protection
equipment (harnesses, lanyards) and devices (guardrails, tie-off points) before each use. Use fall protection
equipment if required for the job. Be sure the fall protection equipment is right for the task, ts properly, and is in
good condition. Refer to U.S. Occupational Safety & Health Administration (OSHA) Regulations Standards - 29 CFR 1926.500, 1926.501 and 1926.502, or applicable national, state or local regulations for more information.
• When using scaffolds, make sure there is proper access, full planking, stable footing, and guard railing.
• When using a boom lift, keep feet rmly on the platform of a boom lift, use fall protection equipment tied-off at
all times to the guardrail or tie-off point.
• When using a ladder, make sure the ladder is non-conductive and the correct size for the task. Read the ladder user instructions and be sure the ladder is in good condition. Make sure ladder is set on stable footing and at
the correct angle.

SAFETY

Overhead Power Lines

Assembling, towing or transporting irrigation machine components such as but not limited to the pivot point, linear cart, span/drive unit assemblies, overhangs and/or corner assemblies underneath or near power lines is
extremely dangerous because of the risk of electrocution.
Operating equipment that elevates irrigation machine components, such as but not limited to an aerial lift or
crane, near power lines is extremely dangerous because of the risk of electrocution. Only qualied personnel
should operate this type of equipment. Before operating the equipment, qualified personnel must read the equipment manufacturers’ operating and safety instructions.
Refer to U.S. Occupational Safety & Health Administration (OSHA) Regulations (Standards - 29 CFR) Cranes
and derricks. - 1926.550, or any other applicable national, state or local regulations for additional information.
• Always presume that any overhead power line is an energized line unless and until the person(s) owning
the line and/or the electrical utility authorities indicate that it is not an energized line and it has been visibly grounded.
• Before operating any equipment near any power line make sure the line has been de-energized and visibly grounded at the point of work.
• Electrocution can occur without touching an electrical power line. Electricity, depending on the magnitude,
can jump or become induced into equipment or conductive materials that come in close proximity to, but do not touch a power line. High wind, lightening, wet ground and other environmental conditions will increase the possibility of electrocution and require additional consideration.
• Transmitter towers can induce the equipment or materials being handled with an electrical charge. Before working or operating equipment near transmitter towers make sure the transmitter is de-energized.
• Select the location where the span/drive unit will be assembled to ensure that neither the irrigation machine,
or the equipment used during the assembly process, will violate the minimum clearance guidelines.
• Never operate equipment or allow the load, ropes or tag lines within 10 ft (3.05 m) of any power line rated 50 kV or lower whether it is energized or not. For lines rated over 50 kV, the minimum clearance shall be 10 ft (3.05 m) plus 0.4 in (1.1 cm) for each kV over 50 kVs. .
• Never assemble, tow, transport or allow irrigation machine components underneath or within 10 ft (3.05 m) of any power line rated 50 kV or lower whether it is energized or not. For lines rated over 50 kV, the minimum clearance shall be 10 ft (3.05 m) plus 0.4 in (1.1 cm) for each kV over 50 kVs. Overhang support angles,
cables and spinner drive components regularly extend 10 ft to 12 ft (3.1 m to 3.7 m) above the irrigation pipeline (span).
• Use barricades to identify areas where interference with overhead power lines could occur. Keep the assembly,
towing or transporting of irrigation machine components and the operation of equipment including load, ropes or tag lines away from any power line, in the distances described above, whether the line is energized or not.
• Always designate a person to observe clearance between the power line and all equipment being operated or moved in order to give timely warning for all operations to STOP if the minimum clearance is violated.

SAFETY

Minimal Lockout / Tagout Procedure

The following procedure establishes the minimum requirements for the lockout of energy isolating devices
whenever maintenance or servicing is done on machines or equipment. It is used to ensure that the machine or
equipment is stopped, isolated from all potentially hazardous energy sources and locked out before personnel
perform any servicing or maintenance where the unexpectedly energized or start-up of the machine or equipment or release of stored energy could cause injury. All personnel, upon observing a machine or piece of equipment
which is locked out to perform servicing or maintenance shall not attempt to start, energize, or use that machine
or equipment.
When the energy isolating devices are not lockable, tagout should be used and affected personnel must wear
full personal protection.
Refer to U.S. Occupational Safety & Health Administration (OSHA) Regulations (Standards - 29 CFR) Typical
minimal lockout procedures - 1910.147 App A, or applicable national, state or local regulations, for additional
information.

Sequence Of Lockout

1. Notify all affected personnel that servicing or maintenance is required on a machine or equipment and that
the machine or equipment must be shut down and locked out to perform the servicing or maintenance.
2. The authorized personnel shall identify the type and magnitude of the energy that the machine or equipment
utilizes, shall understand the hazards of the energy, and shall know the methods to control the energy.
3. If the machine or equipment is operating, shut it down by the normal stopping procedure (depress the stop button, open switch, close valve, etc.).
4. Deactivate the energy isolating device(s) so that the machine or equipment is isolated from the energy source(s).
5. Lock out the energy isolating device(s) with assigned individual lock(s).
6. Stored or residual energy (such as that in capacitors, springs, elevated machine members, rotating flywheels, hydraulic systems, and air, gas, steam, or water pressure, etc.) must be dissipated or restrained by methods
such as grounding, repositioning, blocking, bleeding down, etc.
7. Ensure that the equipment is disconnected from the energy source(s) by rst checking that no personnel are
exposed, then verify the isolation of the equipment by operating the push button or other normal operating
control(s) or by testing to make certain the equipment will not operate. CAUTION: Return operating control(s)
to neutral or “off” position after verifying the isolation of the equipment.
8. The machine or equipment is now locked out.
!
DANGER
•WHEN PERSONNEL WILL BE EXPOSED TO CIRCUIT ELEMENTS AND ELECTRICAL PARTS, A QUALIFIED PERSON MUST USE TEST EQUIPMENT TO VERIFY THAT THE CIRCUIT ELEMENTS AND EQUIPMENT PARTS OF THE EQUIPMENT ARE DE-ENERGIZED.
Restoring Equipment To Service
When the servicing or maintenance is completed and the machine or equipment is ready to return to normal
operating condition, the following steps shall be taken.
1. Check the machine or equipment and the immediate area around the machine to ensure that nonessential
items have been removed and that the machine or equipment components are operationally intact.
2. Check the work area to ensure that all personnel have been safely positioned or removed from the area.
3. Verify that the controls are in neutral.
4. Remove the lockout devices and reenergize the machine or equipment.
5. Notify affected personnel that the servicing or maintenance is completed and the machine or equipment is ready to be used.
