The Importance of Helipad Safety &

Potential Dangers to Helipad Operations

David Muthoka Airport Safety Officer, Fujairah International Airport
Potential Dangers to Helipad Operations
Around your helipad establish a safety zone and always wait for the helicopter from the safety zone and only approach when asked to.
safety zone
Never approach the helicopter from the rear
Helicopter Safety Zones
Always approach the helicopter from the front and in full view of the pilot

approach the helicopter
Crouch when approaching or leaving the helicopter. This creates more space between head and rotor blades
 leaving the helicopter
Always approach or leave on the downslope
approach or leave on the downslope
If blinded by swirling dust or sand ; sit down and wait for assistance.
sit down and wait for assistance
Helipad maintenance
Foreign Object Debris‐ FOD
Foreign Object Debris
Clear all FOD (loose stones, metal pieces, clothing etc) on the helipad.

Wind sock

Wind sock
It is good practice to put up a wind sock to assist pilots in determining wind speed and direction. Periodically check for wear & tear.

Helicopter approach path

Helicopter approach path
Ensure that there are no trees power lines trees, lines, poles, or overhead obstructions on the arrival /departure path of the helicopter.

Landing area

Landing area
Ground helipads need to be checked for uneven areas. It should be kept evenly leveled and the grass/ vegetation growth cut low.

Fire fighting equipment

Fire fighting equipment
Ensure that there are fire fighting extinguishers in place just in case of any fire emergency.

Helipad lighting

Helipad lighting
Ensure that the helipad lights are in good working condition and the fittings are not loose.

Operations & Standard Operating Procedures


For a safe and efficient operation procedures should
be developed.
General
Be aware of rotor wash.
•Beware of protrusions e.g. radio antenna , pitot tubes (don’t use as handles, at eye level when crouching).
•Remove all loose items or hold tightly onto them.
•Beware of tail rotor (invisible when spinning).
•Only delegated people should handle the loading/ unloading of cargo.

Ground to Air radio communication( if using a radio).
Know how to use the radio properly.
• Pre‐arrange with pilot on a common frequency.
• Ensure your radio is programmed on the frequency.
• As pilot approaches convey information on wind ‐ if steady or gusty, visibility, cloud cover or fog.
• Be brief & concise.
•To contact the pilot use the last 3 letters of the helicopters registration e.g. A6‐
ABC
Safety Management practices
• On the morning of helicopter flying organise a procedural/ safety briefing.
• Keep a log book for helipad operations and log all information relating to helipads here.
• Record what kind of FOD items are found at your helipad.
• Keep a record of mitigations & their effectiveness.
• Do a periodic trend analysis of this data.
• Always ask the pilots what hazard(s) they encountered operating on your helipad & then log it. Always mitigate your hazards.
• Ensure that your helipads are regularly inspected as per your schedule and log all your observations.


Important‐ Appoint a person(s) to be in charge of the helicopter operation and be his/her responsibility to ensure that the procedures are adhered to.


Arriving aircraftcheck helipad for FOD, wind sock, lighting, fire extinguishers in place, safety zones established, crowd moved to safety zones, cargo neatly parked and kept away from helipad. No smoking in /around the helicopter.

Aircraft on ground approach only when pilot or
guide indicates,
Exiting aircraft:‐
Do not remove your seat belt until
the pilot instructs you to do so or a designated
person has opened the door.
Final check:‐Do a final safety check before giving the thumbs up sign. Verify that all seat belts, racks and cargo compartments are properly locked and latched.

AGGREGATES CIVIL WORKS FOR UNDERGROUND CABLE INSTALLATION

Aggregate Civil Works

Aggregated Civil Works and Construction Materials Management in Cable Installation Site

The underground cable installation project is not a contemporary high-tech major aggregates civil work, but some special complaint and engineering practice  should followed to keep the power cable safe and liveliness for long lifetime.

This article is introduced on the aggregated civil work for high voltage electrical power transmission underground cable installation project. The scope of civil works for such project as highlighted as below:
  • Cable trench cutting, bedding, backfilling;
  • Cable protection RCC slab;
  • Pipe trench, bridge trench, road and canal crossing etc;
  • Piling for bridge trench and terminal equipment structure;
  • Cable joint and cable earthing or grounding RCC Bay construction;
  • Concrete structure and foundation for outdoor steel structure, etc.

To ensure quality and follow engineering layout the aggregates for all concrete should be take approval of the Engineer. Un-reinforced mass cement may use first class broken brick, aggregate. Reinforced concrete should use only stone aggregate.

They must be hard, strong, durable, clean and free from adherent coatings and should be protected from contact with any deleterious mater whatsoever.

Sponsored:

Delivery and Storage System

Sufficient quantities of each grade of aggregate should be kept on the site to ensure continuity of work. 


Aggregate of different sizes should be stored in different stacks and the arrangements for storage should be subject to the approval of the Engineer.

Aggregates for Reinforced Concrete

For reinforced concrete work the fine aggregate should consist of clean well graded Sunarganj, Jaladia or Savar sand.

The coarse aggregate for reinforced concrete should consist of well graded Sylhet shingles.
The fine and coarse aggregate should be kept well separated during storage on site and during mixing, measured separately and mixed in the proportions specified or permitted. 
The individual and combined grading should be to the satisfaction of the Engineer.

 Aggregates for Mass Concrete

All brick aggregate should be tested periodically and as often as the Engineer should decide to be necessary, to ascertain the proportions of the sand contents. In such testing the following conditions should be observed:
o  All material passing a 5mm square mesh should be defined as sand and the residue on such a sieve as coarse aggregate.
o The sand and coarse aggregate are to be separated by sifting a dry sample and the proportion of each ascertained.
o  The proportions by volume in a shaken measure are to be approximately one part sand and two parts coarse aggregate.

Sponsored:

Aggregate for cement Mortar

The aggregate for cement mortar should consist of natural sand as specified in British standard BS 1200; sands for mortar for plain and reinforced brickwork. Mortar for brickwork should generally consist of 1 part cement to 0.5 parts to 4 or 4.5 parts of sand as per BS 5628.

Water for Concrete

The size of aggregate effects on workability and strength of concrete and also influences the water demand for getting a certain work-strength and fine aggregate content required for achieving a unified mix.

Water for concrete, cement mortar and grout should be free from salt, oil, alkali, organic matter or other deleterious substances and the Engineer’s approval must be obtained prior to its use. Any tests required by the Engineer on the suitability of the water should be carried out in accordance with BS 3148.

HOW SELECT CONTROL SWITCHES, SELECTOR SWITCHES AND AUXILIARY SWITCHES

Control Switches

Electrical Control, Selector and Auxiliary Switches

Electrical Engineering defines a switch is an electrical device for an electrical circuit to make or break, interrupt or divert the current flow from one conductor to another.

Electrical switch is a very wide range of electrical component sect that control consisting electrical, mechanical, electronic, even more latest micro component devices for making, breaking or changing the circuit connection.

Switches Types

From different point of concept we also can say more about electrical switches- an electrical switching mechanism that controls the operation of a machine is known as control switch or controller; an electrical switch that uses to select for any alternative from provided is known as selector or selector switch; Heavy loaded equipment directly switching is not safe to use line current and voltage, these are operate by some auxiliary devised switches are known as auxiliary switch; an electrical switch that uses for reversing the direction of electric current is known as switch commutator; an electrical device that interrupt electrical continuation is known as cutout switch or fuse; an electrical switch that operates by setting a time device is known as time switch; a switch that operate the solenoid to ignite or starter is known as ignition switch; There are so many electrical switches like push button switch, toggle switch, on-off switch etc..

Switch Selection Criteria and Guideline to Execute an Electrical Construction Project

This guide will show how to select electrical control switch, selector switch and auxiliary switch to execute an electrical construction project by a service provider ensuring national and international standard.

Here below considering al control switches, selector switches and auxiliary switches for construction a high voltage power transmission project. Described switches are used in power grid substation control and switching equipment.

Control Switches

Control switches should be of the three-position type with a spring return action to a central position and without a locking feature.

Circuit Breakers should have control switches which should be labeled open/N/close or (O/N/I) and arranged to operate clockwise when closing the circuit breakers and anti-clockwise when opening them, and should be of the pistol grip type.

Control switches of the discrepancy type should be provided where specified, i.e. mimic panel. Such discrepancy control switches should be arranged in the lines of the mimic diagram. Such switches should include lamps and be of the manually operated pattern, spring loaded such that it is necessary to push and twist the switch past indicating position for operation. The lamp should be incorporated in the switch base and should flash whenever the position of the circuit breaker is at variance with the position indicated by the control switch. Hand dressing of the control switch to the correct position should cause the lamp to extinguish.

Selector Switches

Selector switches should be of the two or more position type as required, and have a stay-put action to remain in any selected position which should be lockable and separate padlocks each with duplicate keys should be provided. Each position of the selector switches should be suitably labeled to denote their function. The switch handle should be of the pistol grip type to the approval of the Engineer.

It should not be possible at any time to operate any switchgear equipment from more than one location simultaneously, and suitable lockable selector switches should be provided to meet this requirement.

The contacts of all control and selector switches should be shrouded to minimize the ingress of dust and accidental contact, and should be amply rated for voltage and current for the circuits in which they are used.
Auxiliary Switches
Auxiliary switches should be to approval and contacts should have a positive wiping action when closing.

All auxiliary switches, whether in service or not in the first instance, should be wired up to a terminal board and should be arranged in the same sequence on similar equipment.

Auxiliary switches mechanically operated by the circuit breakers, contactors, isolators, etc. should be to approval and contacts mounted in accessible positions clear of the operating mechanism of the circuit breaker, contactor, isolator, etc. and they should be adequately protected against accidental electrical shock.

Auxiliary switches should be provided to interrupt the supply of current to the trip coil of each circuit breaker and contactor immediately the breaker or contactor has opened. These auxiliary switches should make before the main contacts, during a closing operation.

A minimum four spare auxiliary switches, two normally open, two normally closed should be provided for each circuit breaker, and contactors and also for isolators.
Final Talk about Switches
It strange to finish the talk about switches in a single article, but at least we understood in a simple that an electrical switch makes either completely on “closed” or completely off “open” to operate an electrical circuit.

SEALING AND DRUMMING PROCEDURE OF UNDERGROUND CABLE


clip_image004[4]

Underground Power Cable Sealing and Drumming Procedure under High Voltage Cable Installation Project

This document established for only on high voltage underground power transmission project’s personnel who are related with underground power cable Packaging, shipping and handling in site; to protect the cable from any damage and easy understand the right handling procedure.

Cable end sealing correctly protects the cable from damage and cable pulling in site become more easy and safe.
·        Wearing cable sealing cap in both side of cable as soon as possible, protect ingress of moisture or water;
·        Cable sealing cap with eye-bolt, helps to cable pulling attaching pulling string;
·        Cable Sealing cap attached with metallic armor rather than copper core, helps to cable laying without damage;
·        Cable sealing metallic cap for metallic sheathed cable ensure long life.

Cable drumming in correct way helps the cable shipping and handling in site becomes less damage and manage to easy.



How Sealing and Drumming the Cable

Immediately after tests at the Manufacturer’s Works, both ends of every length of metal sheathed cable should be sealed with a metal cap which should be plumbed to the sheath.

Non-metal sheathed cables should have both ends of the cable sealed with a suitable cap which should not become punctured during transportation.

The ends of the factory lengths should be marked “A” and “Z”, “A” being the end at which the sequence of core numbers is clockwise.

Both cable ends should be kept within the drum flanges and battens. For oil filled cables, cable drums should incorporate and oil tank. The oil pressure in oil-filled cables should be constantly maintained above atmospheric pressure at all times. The oil pressure measured at the factory should be recorded on the drum, together with the temperature at which this measurement was made.

The cables should be wound on strong steel cable drums provided with wooden battens to protect the cable form damage. The drums should be arranged to take a round spindle and should be marked to indicate the direction of falling. Timber should be impregnated against for and termites.

Any cable required to be recovered is to be capped, connected to oil tanks if necessary and re-drummed following lifting.

Ensure Safety Induction during Commissioning

Considering the Cable Installation Site Situation

It is the service provider’s responsibility to ensure that he acquaints himself with the nature of the ground conditions prevailing in site transporting and in particular with the proposed cable routes.

The installation site situation for cables should be consider during financial quote in the schedule, should include for any and all types of excavation and back-fill on the “As found” basis.

Where cable routes pass along narrow roads the Service provider should allow for removal of trench spoil as it is excavated to avoid blocking access to the trench and to local houses and shops. If the road is surfaced back-fill is required to be sand of approved quality. All measurements should be made in lineal meters.
