PREPARATIONS

Directly out of Operator manual

IT’S ALL ABOUT HABITS

• Proper PPE– Safety glasses– Dielectric boots/gloves– Grid mats– Hi-Vis vest– Hard hat if working under load or falling objects– Hearing protection

• Inspect PPE to manufacturer’s recommendations

• Remove jewelry• Tie back hair• No loose fitting clothing• Traffic/pedestrian control• Look at surroundings, survey work and

structures• Two-way radios for tracker and operator

PREPARE CREW

• Read operator’s manual

• Know safety signs

– Meanings located in operator’s manual

PREPARE CREW

• An emergency response plan should be created and communicated to entire crew in the case of an underground strike and/or jobsite injury– Plan should include:

• contacts with phone numbers

• procedures for each type of event

• assignments of responsibilities

• exit route(s) if necessary

• meeting place

PREPARE CREW

• Have all underground utilities located– Contact One Call 811 (US/Canada)

• Some companies do not participate in One Call– Business parks, universities, schools, government and military

land

• Rest of world- Contact utility companies individually, One Call service or locating service

– Locate all active and abandoned

utilities

– All utilities that do not participate in

one-call must be contacted

CALL BEFORE YOU DIG – “IT’S THE LAW”

• Standard color codes for utility markings

• Use Ditch Witch Electronics to Sweep for Live Power BEFORE you Bore.

SWEEPING FOR POWER EVERY BORE

Verify all locatesFact: CGA reported that approximately 74% of known

damage events in 2012 had a locate ticket called in.

UTILITY DAMAGE STATS

• Potholing– “Daylight” the utilities– Vacuum excavate or

hand dig only within 24” of utilities

– Always dig 12”-18” below utilities

– Inspect for any evidence of any underground hazards• Manholes, meters, vaults,

light/power poles, sunken ground, etc.

CROSS-BORE AVOIDANCE

PROPER TRAINING REQUIRED

Is it necessary to locate sewer lines on the jobsite prior to drilling?

QUESTION

Yes.

It is highly recommended to locate sewer lines. The most popular method is utilizing a sewer beacon

and tracker to find the running line and depth

Additionally, plan to have a camera inspection of all sewer lines in the area after boring is complete.

ANSWER

• Sewer Locating

CROSS-BORE AVOIDANCE

• Review bore plans

– Make pre-bore profile

– Mark proposed borepath

– Sweep for power

– Soil testing for mud mixture

DANGERS OF OPEN PITS & DHT

OPEN PIT DANGER

Never enter “any” pit with live drill string

(machine must be shut off!)

Keep all rigging to a minimum

Use proper slings, duct pullers, shackles and swivels.

Backreaming Tips• Plan backreaming job before drilling. Plan bore path as straight as possible. Check bend limits ofpullback material. Check that appropriate pullback devices are on hand.• Keep all bends as gradual as possible.• Drilling fluid quality is a key factor in backreaming success. Contact your Ditch Witch® dealer forinformation on testing water, selecting additives, and mixing drilling fluid.• Backreaming requires more fluid than drilling. Make sure enough fluid is used.

Swivels are directionaland require inspection & maintenance

WHY WE SWEEP FOR POWER

86 SERIES BEACON DEPTH CALIBRATION

• Calibration Procedure– Install beacon in housing.

– Place 10 ft. from tracker.

– 20 ft any other metal objects.

– Turn unit on.

– Press/hold depth and up arrow until CAL appears.

– Verify calibration at 15 ft.

– Repeat this procedure for second frequency when calibrating for dual frequency beacon.

86 Series Beacon Depth Calibration

• Calibration Tips– Beacon and tracker should not be

moved/rotated until calibration is complete.

– Large metal objects, rebar, power lines and other kinds of interference will affect calibration.

– Calibrate at the jobsite.

– Only depth estimation is affected by this calibration.

Interference can come in two forms either

• Active

• Passive

These types of interference can cause

- Loss of beacon information

- Erratic beacon signal

- Inaccurate depth estimates

- Difficulty in locating

INTERFERENCE CAN COME IN TWO FORMS:

Forms of Active InterferenceForms of Active Interference

Forms of Passive InterferenceForms of Passive Interference

Checking for interference and noise with your tracking system.

CHECKING FOR INTERFERENCE AND NOISE WITH YOUR TRACKING SYSTEM.

WHAT CAN BE DONE ABOUT SHALLOW NOISE FLOORS?

Identify what the inference is and see if it can be eliminated (see if power can be shut off, turn off the LMS signal if possible, wait for weather system to move through).

Try to separate yourself/bore path away from the interference (change direction of bore, use an offset/drill too technique, change time of day for bore).

Use another beacon with a stronger output signal such as a BH or BHX beacon to help break through the noise.

Try a beacon with a different frequency ( 12kHz vs. 29kHz or 1.75kHz vs. 11.2kHz) or a different tracking system 8500 instead of 750.

TROUBLESHOOTING 752 TRACKING SYSTEM

• Tracker not communicating with remote display.– Ensure radios in both units are on same channel.

– Make sure radio is turned on.– Radio Test Mode

• Tracker and Display must be on the same channel. • With Tracker off, press and hold fore/aft/left/right arrow button while

turning the tracker on. Release F/A/L/R when test appears on screen. • Check Remote Display for information changes on screen. • Process of elimination

– Perform visual inspection of keypad and overlay.

BATTERY TROUBLESHOOTING

True or False, batteries are the number one cause of units being sent in for repair?

•Use a very good quality alkaline only. (Duracell Procellrecommended). •Age of batteries, are they new and fresh?•If you change one, change them all.•Do not mix battery brands.•Contacts, make sure contacts are clean and not corroded.

Battery Troubleshooting

• Avoid known battery manufacturer's using

recessed negative contact points. (Such as

Panasonic Alkaline Plus, Panasonic Industrial

manufacturers Alkaline AM-2PI and Kodak

LR14 Alkaline.

VACUUM EXCAVATION

Day 2

Vacuum Training Course

Why We’re Here

•Vacuum Trailers provide operators with:• Ability to keep jobsites free of

debris that can be a safety hazard.

• Ability to “daylight” utilities more effectively and safer than mechanical excavation

• Efficient means to clear work areas to perform tasks.

• Environmentally safe means to store, transport, and dump all debris in designated locations.

Watch Vac Safety Video

Potential Hazards• Struck by• Crushing• Fire• Electrocution• Suffocation

Precautions• When driving, consider effects of sloshing water or

spoils in tanks. Make sure tow vehicle is appropriately sized.

• Wear appropriate personal protective equipment as needed. Consider hard hat, safety glasses, gloves, boots, metatarsal guards, and hearing protection.

• When cleaning filter, use respirator if necessary depending on material excavated.

Dielectric Boots and Gloves• Wear appropriately rated electrically insulated boots

with pant legs tucked in, and appropriately rated electrically insulated gloves when operating on an electrical jobsite. If using water, dielectric boots should be worn.

Precautions• Keep pressure wand away from body parts.• Do not put the end of the suction hose or tools on

any body part.• Do not open spoils tank door or filter doors until

tank has been de-pressurized (reverse flow) and fluids and any flow-able spoils have been emptied.

• Reverse flow should not be engaged unless tank drain valves are open first.

Precautions• No one should be under raised components, such as

the tank door or the raised tank, without using lockout devices.

• Drain fluids and flowable spoils before raising the tank.

• Stay away from door when dumping.• Ensure you have a clear view of the door area and

beneath the tank when closing door or lowering tank.

Precautions• Flammable material should not be vacuumed. If

using vacuum in the presence of natural gas, precautions should be taken to ensure inlet air/fuel ratio is outside of flammability range. This should only be performed by qualified individuals using appropriate measuring devices.

• Do not enter a spoils tank unless it has been evacuated with fresh air.

Information/Facts• High pressure water can cut through skin, wood, and

metal.• Utility age and physical composition can affect

vulnerability to damage by wand.• Suction can quickly suffocate and can pull blood

through the skin.• High pressure water can cut through clothing and

skin.

Information/Facts• Static charge can build in the vacuum hose. This can

generate a spark and depending on the conditions and material being excavated may ignite.

• Hazardous materials require special transport vehicles. Most vacuum excavators are not equipped to transport hazardous materials.

• High pressure water can cause excavated material and rocks to be thrown.

Best Practices

Trailer InspectionVacuum equipment checks are vital to equipment function. Some examples are:

• Checking the fluid levels.

• Checking equipment for wear and tear.

• Trailer hitch inspection.

Job Planning• Identify and communicate any hazards• Have a valid locate on site before starting the

excavation• Classify jobsite (soil, traffic, locate marks, possible

un-marked utilities, etc.)• Work interruption (action plan incase of damaged

underground utilities)• If trying to locate a damaged utility, that line should

be de-energized and isolated prior to excavation.• Appropriate warning signs and/or barriers

Trailer Setup

Positioning the equipment correctly has several steps: – Proper trailer positioning.

– Proper equipment stabilization.

– Chock trailer wheels.

– Maintain proper boom clearance for overhead lines

Personal Protective Equipment• The wand should never remain motionless.• Do not aim directly at utilities.• Maintain as much distance as possible between the

end of the wand and the utility. At least 8” is recommended, depending on the nozzle used.

• Never use more pressure than what is necessary to break up the soil.

When Exposing Utilities• The minimum requirement for safety equipment to

be used by workers should be:• Approved head protection• Approved foot protection• Approved eye protection• Approved hearing protection• Approved clothing (flame-resistant if needed)• Suitable hand protection

Turbo/Rotary Nozzle• The use of a Turbo or Rotary Nozzle

should always be used to minimize any possible damage to utilities and increase excavation production• Maximum water pressure using a rotating

nozzle:All depths -- 3000 psi

• Maximum water pressure using a straight tip:

0-18” deep -- 2500 psiOver 18” deep – 1500 psi
