Safe DrıvıngVehicle Considerations

• Pre-Trip Inspection - Ensure mirrors, signals and

lights are clean and not broken, tyres are properlyinflated with acceptable tread wear.

• Inside the Vehicle Adjust your seat and fasten seat belt. Check and adjust all Mirrors. Adjust your Headrest. Assure doors fully closed and secured.

Check windows/windshield. Sufficient fuel for the planned journey. Adjust the vents, windows, heater & air conditioner. Where ever possible material and passengers are to

be carried separately. If carried in the same spacethe materials are to be secured to prevent injury to

P a g

passengers in the event of a collision.

• Routine maintenance

Get regular tune-ups, oil changes and brake inspections.• Tyres

Maintain proper pressure (measure when cold),under or over-inflated tires can lead to a blowout.

Check tread wear. Ensure appropriate tyres are fitted. Rotate tires.

• Windshield Wipers

Change if hard, cracked or brittle; check wiper fluid.• Check fluids

Oil, transmission, radiator and brakes. Fill the antifreeze in the winter and coolant in the

summer. Fluid leaks are a sign you are overdue for

maintenance.

• If equipment comes into contact with a power Line: Do not attempt a rescue until the electric has been de-

energized. Keep non-emergency personnel at least 90maway.

Notify the emergency services immediately.

Have the equipment operator stay on the equipment until

advised that it’s safe to get off. If fire or other danger forces the operator off, have them

jump clear without touching the ground and theequipment at the same time, shuffle or hop until at least9 metres clear.

Fire SafetyFire Rules

If You discover a fire or suspect a fire

• Raise the ALARM and initiate an evacuation• Call for the Fire Service• Evacuate to the assembly point• ONLY IF it is SAFE to do so attempt to extinguish

the fire. Always position yourself with an exit or means of

escape at your back before you attempt to use anextinguisher to put out a fire.

• Leave IMMEDIATELY on hearing the alarm or ifinstructed to leave the area.

P a g

Never Fight a Fire• IF YOUR INSTINCTS TELL YOU NOT TO.• If you don't know what is burning.• If the fire is spreading rapidly .• That is producing a large amount of smoke .

• If you don't have adequate or appropriate equipment.

Fire SafetyHow to use Fıre Extinguishers

Most fire extinguishers operate using the P.A.S.S.technique:

PASS = Pull - Aim - Squeeze - Sweep

PULL... Pull the pin. This will also break the tamperseal.

AIM... Aim low, pointing the extinguisher nozzle (orits horn or hose) at the base of the fire.

SQUEEZE... Squeeze the handle to release theextinguishing agent.

SWEEP... Sweep from side to side at the base of

P a g

. Watch the area. If the fire re-ignites, repeat steps.

If you have the slightestdoubt about your ability tofight a fire

....EVACUATE IMMEDIATELY!

Excavations

P a g

Ensure that the sides of an excavation pit are properlyshored before you go down to work.

• Proper shoring,access ladders andbarricades areessential safety itemsin excavation works.

• Ensure their presencebefore you enter anexcavation to work.

Confined Spaces

• Confined spaces can include cellars, pits, tanks,drains, manholes, sewers, and even some typesof excavation. Some are more obvious thanothers, but confined spaces are more commonon construction sites than we realize.

Consider what may

comprise a confined

s ace on our site!

Main Points:

P a g

A risk assessmentshould be carriedout for all confinedspaces.

Never ever workalone in a confinedspace.

Confined Spaces

• Other Points: Confined space atmospheres should be checked

prior to entry.

Suitable PPE should be worn which may includebreathing apparatus, and may require specialisttraining.

Work in confined spaces must be supervised,

either physically or by communications/monitoringequipment (remember failure procedures).

Ensure any recovery equipment is checked and

serviceable prior to starting work.

P a g

Don’t attempt a rescue without first sounding thealarm.

Always leave a confined space immediately if toldto do so.

Don’t eat, drink, smoke, or used naked flames inconfined spaces or in close proximity to entry.

Remain alert to any changes in thesituation/environment. If in doubt - get out.

Laser / Fibre Optic Safety

Bare Fiber Safety• If the shards get

into your skin, youwill have to wait forthem to work out.

• Wear eyeprotection!

• Put shards onsticky tape.

• Account for allshards.

Eye Safety Rules

• Never look into theend of a cable thatmight be in use.

• Cap all unusedconnectors.

• Tape un-terminatedfiber ends.

• Mark enclosures withwarning labels.

• Laser test sources aredangerous, don’t leave

P a g

• Only authorized-

trained employeesmay:

Install

Service

Maintain fiber-optic systems

that are notenclosed.

.

NEVER look directly into a fiberend, a laser source or point alaser in your eyes or at others!

RF SafetyCompliance Boundary / Exclusion Zone

Effects of RF Exposure

• Tissue heating (effectsvary with exposed bodyarea).

• Skin sensation - ONLYfrom EXTREMELY highexposure.

• RF burns from touchingan energised source.

• Electric shock frominduced currents.

Compliance Boundary

• In principle, RF levelsdecrease rapidly when aperson moves furtheraway from the sourcee.g. a transmittingantenna.

• The distance at whichthe RF level is alwaysbelow the RF limit iscalled the ComplianceBoundary.

P a g

• Areas which areintended to be accessedby the general public will

not exceed the RF limitsfor either the generalpublic or workers.

• At outdoor base stationsites the RF limits willnot be exceeded atground level for eitherthe general public orworkers.

Exclusion Zone

• The region inside theCompliance Boundary isoften called theExclusion Zone.

RF SafetyGeneral Procedure for Antenna Sıtes

• Assume all antennas are active, all personnel entering

the site must be authorised and obey all posted signs,warnings and instructions.

• Prior to arrival or before approaching transmittingantennas, be sure you aware of and understand thecompliance boundaries and the locations of theantennas.

• If there is a need to climb masts/towers or work within 5metres of a roof top antenna a site safety briefing isrequired before starting work.

• If it is necessary to work within the compliance boundary,follow the procedure for requesting the antenna to be

P a g

.

• Never disconnect RF cables or connectors associatedwith a operating antenna since this may result in an RFburn through direct contact with RF conductors.

• Damaged cabling and connectors can be unwantedsources of RF exposure – report all such cases.

• In addition to RF cabling, some base stations may havefibre-optic distribution systems. Workers shall follow thespecific rules dealing with optical emissions.

• Without further analysis, personnel with active medicaldevices should not enter areas above the general publiclimits .

• Always follow the manufactures installation andoperating instructions.

RF SafetyTypes of Antennas

Omni-directional coverageThese antennas radiate RF energy equally in alldirections in the horizontal plane.

The antenna input power is typically 10 – 80 watts, andthe compliance boundary for a worker typically extends0.1 – 1.5 meters from the antenna.

Sector coverageThese antennas restrict most of their radiated RFenergy to a narrow angular sector in their forwarddirection (typically 60 to 20 degrees in the horizontalplane, typically 8 to 4 degrees in the vertical plane).

The antenna input power is typically 10 – 80 watts, andthe compliance boundary for a worker extends typically0.2 – 3 meters from the front face of the antenna .

Antenna farms (or clusters)Antennas are often grouped together on masts .

P a g

-directional antenna mounted above a cluster of 3 sectorantennas.

In the case that multiple antennas are present on a site,whenever an additional antenna is installed, thecompliance boundary of each antenna should beevaluated again, taking into account the additionalexposure of the newly installed antenna.

Radio relay (Microwave / fixed point-to-point link)These antennas concentrate their RF energy into anarrow beam in the forward direction. Since the powerlevels are typically low, less than 1 watt, the safetydistances in this forward direction (L) are often small (in

centimetres) and in many cases there is no need of anysafety distance for occupational exposure .

Areas above, below and to the sides of the antenna, aswell as the area behind the antenna, are normally safeat even shorter distances.

The Compliance Boundary for safe working around antennas is shown inBLUE - Seek clarification before approaching antenna or working within 5m
