Safety

Use of Personal Protective Equipment

• People working in areas where there are potential electrical hazards must use, personal protective equip-

ment that is appropriate for the speciﬁc 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 ad-

ditional 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 neces-

sary 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 begin-

ning 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, ﬁts 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 ﬁrmly 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

Minimum Working Clearance

To reduce the risk of injury, all persons require adequate working clearance around the electrical panel or other

electrical equipment. The table below identiﬁes the minimum working clearance needed. Refer to U.S. Occupa-

tional Safety & Health Administration (OSHA) Regulations (Standards - 29 CFR) Safeguards for personnel pro-

tection. -1910.303(g)(1)(i), or any other applicable national, state or local regulations, for additional information.

Qualiﬁed Person

A Qualiﬁed person is one who, by possession of a recognized degree, certiﬁcate, or professional standing, or

who by extensive knowledge, training, and experience, has successfully demonstrated his/her ability to solve or

resolve problems related to the subject matter, the work, or the project.

Only qualiﬁed persons may work on electric circuit parts or equipment that have not been de-energized.

Refer to U.S. Occupational Safety & Health Administration (OSHA) Regulations Standards - 29 CFR 1926.32(m)

and 1910.333, or applicable national, state or local regulations for additional information.

Irrigation Equipment near Airports and Crop Dusting Aircraft

• If any part of the irrigation machine comes within 3200 ft (975 m) of an airport runway, especially the ap-

proach (ends) of the runway, additional warning markers may be required. In the United States, CFR Title

14, Chapter I, Subchapter E, Part 77 – Safe, Efﬁcient Use, and Preservation of the Navigable Airspace

describes when marking is needed.

This document is available at: www.ecfr.gov

• Marking requirements vary depending on the location of the irrigation equipment relative to the runway, the

type of airport (Civil, Military, or Heliport) and other factors. Contact the local airport authority for guidance

and speciﬁc recommendations. In the United States, guidelines for marking structures near airports are

published by the Federal Aviation Administration in Advisory Circular AC 70/7460-1L – Obstruction Marking

and Lighting.

Available here: www.faa.gov/regulations_policies/advisory_circulars

• For irrigation machines near private or unregulated airﬁelds, including farm-based airstrips, Valley strongly

recommends complying with the same standards and requirements as Civil airports as shown in Part 77.

• Regulations vary by country, contact your local aviation authority for guidance.

Overhang cables, including overhang back cables are a particular danger. In locations where low-ﬂying air-

craft are likely, such as within 1,500 ft (457 m) of an end of an airport runway, or where crop dusting aircraft

are common, Valley recommends adding obstruction markers to overhang cables to improve their visibility.

For large overhangs (36 ft / 10.97 m Heavy Duty and longer), ﬁve 12 in (300 mm) or 20 in (500 mm), aviation

orange marker balls are sufﬁcient. One near the rabbit ears, two in the middle of the back cables and two in

the middle of the highest overhang cables. Refer to Section 3.5 in AC70/7460-1 for additional details. Avia-

tion marker balls are available online and from a variety of aviation and airport safety equipment providers.

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 qualiﬁed 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 as-

sembly, 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 person-

nel 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 equip-

ment 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. De-activate 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 ﬂy-

wheels, 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 ﬁrst checking that no personnel

are exposed, then verify the isolation of the equipment by operating the push button or other normal operat-

ing 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 non-essential

items are removed and that the machine or equipment components are operationally intact.

2. Check the work area to ensure that all personnel are safely positioned or removed from the area.

3. Verify that the controls are in neutral.

4. Remove the lockout devices and re-energize 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.

Safety

Operate Safely

Valley Irrigation machines are designed with safety in mind. However, if this machine is operated incorrectly, it

may pose a safety threat to the operator. A good safety program is much like a chain, it is only as strong as its

weakest link. The manufacturer, dealer, and operator must maintain and improve all safety programs. Following

is a list of safety operating tips which you and all other persons servicing or operating the machine must read

and understand:

!CAUTION

•DO NOT OPERATE THIS MACHINE WITHOUT

FIRST READING THE OWNER’S MANUALS

FOR THE MACHINE.

•READ ALL SAFETY MESSAGES IN THIS

MANUAL AND SAFETY SIGNS ON THE MA-

CHINE.

•DO NOT LET ANYONE OPERATE THIS MA-

CHINE WITHOUT PROPER INSTRUCTIONS.

•UNAUTHORIZED MODIFICATIONS MAY IM-

PAIR THE FUNCTION AND/OR SAFETY OF

THE MACHINE.

•IF YOU DO NOT UNDERSTAND ANY PART

OF THIS MANUAL, CONTACT YOUR VALLEY

DEALER.

EMPLOYEE INSTRUCTION ON SAFETY

It is very important to instruct your employees on

the safe use of this equipment at the time of their

initial assignment to operate it. DO NOT let anyone

operate this equipment without proper instructions.

Safety training should be presented annually and

the service manager should ensure employees fully

understand the safety messages and what to do in

case of emergencies.

EMERGENCY STOPPING

The machine can be stopped at any time at any tower

by turning the disconnect switch, located underneath

the tower box, to the OFF position. Refer to Figure

10-1.

Figure 10-1 1. Disconnect Switch

!WARNING

PROPER GROUNDING

DO NOT attempt to start the machine until the

electrical service is properly installed and grounded

by a qualiﬁed electrician as per the electrical

standards. Refer to Figure 10-2.

If the power supplied to the machine is not grounded

properly, severe injury, or death can result should an

electrical malfunction occur.

It is your responsibility to ensure that your power

supplier and/or electrical contractor has grounded

the irrigation machine as required by the National

Electrical Code and by applicable local electrical

codes. If a machine is properly grounded and fuse

sizing is correct, there is extremely low probability of

an individual being injured by electrical shock.

•All 480 VAC, 60 Hz (380 VAC, 50 Hz) power

supply services MUST be a 4 conductor

service.Three 480 VAC (380 VAC) power lines

and one ground conductor which is as large

as the power carrying conductors for that

service.

•Each time a towable machine is moved,

the ground wire MUST be reattached to the

ground rod and checked for electrical integ-

rity before restarting the machine.
