13. MARKING AND FENCING

Before starting a job, delimit and signal the work area, to warn and prevent access of people not involved in the activity.Signals should be clear when interpreted, legible from a prudential distance and should state reality, no to mislead regarding the warning. Remove signals when they are no longer requiredThe openings made on floors, either excavations or removal of gratings should have a rigid protection and signaling fencing.The stakes used to tie danger or warning tapes should have 1 m of useful height, make sure there are no underground installations (wires, pipes, etc.) and place them at a safe distance from risk.Protect the free end of the stake with caps, to avoid the risk of impaling.During reduced visibility hours, flashing lights signaling should be used.Danger or warning tapes offer no physical protection. Remember: the yellow and black tape means precaution; the red and white tape, danger. Use the corresponding one, and replace signaling if it was damaged by the wind.Do not jump over or go underneath the danger tapes or safety fencings.

14. EQUIPMENT AND FACILITIES BLOCKINGWhen working on electrical lines, pipelines or pieces of equipment that can be activated suddenly, perform the corresponding lock out and signaling of the facilities with pliers, padlocks and/or tags.Remember to remove the tag and the lock once the job is completed. The tag should be destroyed not to be used again. Do not put in service a facility with a tag that is not yours nor remove it.

29

15. LADDERS AND SCAFFOLDS

Ladders:•Ladders that are cracked, broken, spliced or have missing elements and

accessoriesshould be taken out of service.• In order to prevent hiding cracks or failures, they will not be painted, if protection is required, colorless products will be used.• The ground under the ladder should be level and firm, and the ladder should be tied in its upper part.• The three top rungs should not be stood on. Use a ladder that has the proper length for the jog.• All ladders should have slip resistant feet.• The support angle will prevent ladder sliding or turning over. The base separation distance will be 1/4 the height of the ladder support point, approx. 75° from horizontal.•When performing electrical jobs or working near electrical lines use dielectric ladders.• Movement on the ladder will be facing the ladder and holding it with both free hands.

• Do not use the ladder as working platform, the have not been designed to withstand such effort.• Extension ladders should have their safety hooks well locked and all accessories in good conditions (anti-slipping feet, pulley wheel, rope and locks).•Scissor-type ladders should be opened, and the opening limiting device fully extended. Level ground support for all four of its side rails should be provided. Do not work on top rungs and do not straddle.• If work has to be performed behind a door or in transit areas, delimit and signalthe place.• Do not leave objects or elements hanging from or resting on ladders.•Keep them clean, free of grease and mud, and store them in appropriate

places.

Scaffolding:

• The scaffolding used should be complete. This means: 60 cm working platform as minimum, toe board, midrail (at 50 cm), toprail (at 100 cm) and independent access ladder. The scaffolding structure should not be used as ladder.• The working platform planking should be firmly tied to the scaffolding

structure,

30

no planking will overhang more than 20 cm or less than 10 cm. They will be 5 cm (2”) thick and will be free of cracks and knots.• Well leveled and firm ground support should be provided for the scaffolding, they should be rigid and if necessary tied to fix and safe point to prevent falling. When higher than 6 meters, they should be sized or verified by means of calculation.• Assembly or disassembly will be performed by competent personnel, under the supervision of the operator crew chief. The materials should be moved safely, with ropes and appropriate containers as required.• Mobile scaffolds should have their wheels locked when working on them. When moving them, there should be no operators/tools on the platform.•Before starting any job, perform a general inspection of the scaffold, checking that all parts in perfect conditions.• Do not alter, by cutting, drilling or welding, any piece of the scaffoldSuch as scaffold bodies, pipes, knots, bases, wheels, etc.• It is forbidden to climb or work on the rails or ledgers of the

scaffold, the ladder and the platform will be used.

Hanging work platforms:• Hanging scaffolds and chairs suspended from a hoisting device require special control. Hoisting accessories, either manual or electrical should be inspected before starting the work day.• The operator will have its safety harness hooked to an individual

lifelineand independent from the work platform.

16. JOBS WITH RISK OF FALLING INTO WATERWhen performing jobs in the jetty area or in vessels, the following requirements should be considered:• Whenever possible, install rigid guard-railsto prevent falling into water.•Use safety harness and/or lifejackets, as appropriate.•Have a lifebuoy with a rope available in the workplace.

31

• Know how to proceed in an emergency.• Perform tasks with another operator, to provide aid in case of an emergency.

• Bear in mind the emergency phone number 106 of Prefectura Naval Argentina.

17. EXCAVATIONS• Before starting the excavation work, the possible presence of underground facilities should be considered. For this purpose, interference diagrams will be requested and the corresponding permits will be required to the Engineering and Development Department of this Consorcio, or to the Utilities Companies (electricity, water, gas, telephone, etc.).• Uncover the facilities manually, do not use machinery.•Signal and fence to prevent people or vehicle falling. Foresee an access to inside the fencing.• According to the type of ground and the excavation depth, accidental cave-ins should be avoided by soil supporting (timbering or sheet piling, or sloping.

• Before starting the working day, and periodically, inspect the excavation, particularly after rain or frost, checking soil stability.• The excavation access and exit should be made using ladders.• Extracted soil and materials should be collected at a minimum distance of one

32

meter from the excavation edge. If the excavation is significant, check that the weight of the material extracted does not cause the sliding and cave in of the edge. In this case, the storage area distance should be bigger.• A deep excavation must be considered a confined space, due to its escape way restrictions or due to the presence of gases and chemicals heavier than air.• No operator should remain in the excavation if there are machines or pieces of equipment operating nearby. Vibrations may affect soil stability.• Do not jump over an excavation and do no improvise way

through with pieces of wood orloose planks, use appropriate walkways.

18. ELECTRICAL RISK•The supply of electrical energy to the facilities and machinery will be made with a board with the corresponding protections: thermo magnetic keys, differential circuit breaker and grounding.•The boards and terminal blocks will be covered and closed on every side, for protection against any accidental contact. If they are outdoors, they will be weatherized.• At the end of each working day, the machines, pieces of equipment and boards will be unplugged. Cables and extension cables will be coiled.•Cable extensions will have double insulation and the connection will be made with standardized plugs. They will be laid over dry places, where they do not interfere with vehicle or people traffic. The use of extension cables in reels or coils will be avoided, they will be fully laid or, even better, appropriate length extensions will be used.• All equipment, ladders, and manual tools and personal protection elements used to work on electrical installations will be dielectric.•Work on electrical circuits:

· The operator assigned to perform tasks related to electricity should be trained and skilled accordingly.· Work on electrical equipment and facilities should be performed with no voltage.· Every electrical facility should be considered energized until the absence of voltage is tested.· Lock out the facility and consider the main 5 steps without skipping any:

33

1. Visible cut of electrical energy supply.2.Cut off elements locked open. Use of tag and lock to prevent accidental activation.

3. Check the absence of voltage with appropriate instruments.4. Make the corresponding grounding and shortcuts.5. Signal and delimit the work area.

• Electrical safety distances:To avoid electrical discharges between energized lines or pieces of equipment and non insulated materials or tools, the electrical safety distances should be respected, considering the voltage level present and the atmospheric conditions.

19. MACHINES AND TOOLS•Machines, pieces of equipment and tools should be and kept ingood use conditions. Perform a periodic inspection of every part.• The elements with operating or use deficiencies should be taken out of service until repair. The will be tagged DO NOT USE.• The operators will use the tools according to their training. Each tool is designed for a specific job, do not alter or modify it.• Work in a comfortable and safe position.• Hand tools:

· Tools in bad conditions are dangerous. A hammer with a loose handle may fly away and hit a person or object; a wrench may slip and generate an operator abrupt movement.· Do not use homemade or bad quality tools.· Keep them in good condition, clean, sharpened and oiled.· Do not subject tools to efforts higher than their capacity; do not use pipes or similar elements to increase the lever arm.· Use a tool bag to take hand tools, or to climb up or down stairs. Do not hang them from the safety harness. Do not carry them in your pockets.

• Electrical and pneumatic tools:· When repairing a machine, or replacing accessories, disconnect the machine electrical or pneumatic supply. Purge the air

34

in the hoses.· Use appropriate tools to adjust or release cutting discs, bits, etc.· Fire risk is always present, keep the area free of clothes, papers, oils and greases and control sparks. We aware of fire extinguishers location.· Do not operate any machine without the corresponding guards and protections.· When operating electrical drills, circular saws, grinders, etc., be always aware of the possibility of jamming up, which considerable increases the torque that may take the machine out of the hand. Take it with both hands and in a firm position.· Be alert to release the trigger upon any abnormal situation.· Use tight clothes, hair tied and keep finger away from moving parts. Use a brush to remove shavings.· Use cutting discs and bit appropriate for the material to work on and the rotating speed of the machines.· Electrical machines will have the corresponding grounding.

20. WELDING AND OXYCUT

• Inspect the equipment before starting to work, check cables, hoses, pliers, spark arresters, pressure gauges and flow meters, etc. and replace any defective element.• Do not lay hoses or cables across places foreseen for transitand circulation.• Avoid breathing the welding gases and fumes. In closed rooms, useextractors, fans or mask with the appropriate filter.• If the tasks will be performed in areas with explosion risks, all

necessary Precautions should be taken; ventilate the area well, measure air explosivity, etc.• Keep spark and slag reach under control, clear combustible materialsfrom the area and have a fire extinguisher at hand.• Put fireproof screens, tents or curtains to protect the other operatorsfrom sparks and radiations.• Use hide apron, jacket and pants, gloves, gaiters or sleevesas appropriate.•All appropriate precautions should be taken at lower levelswhen performing welding jobs in elevated locations.•Electrical welding:

35

· Apply grounding to the piece to be welded and as close as possible to the welding point.· Do not throw to the floor the electrode remains, especially if there are operators working at a lower level. Put them in a container.· Face protections will be provided by welding mask with filter Number 10 or higher.

• Oxyacetylene cut and welding:· The tubes should be protected with valves that prevent back flame (spark arrester), flow excess safety valve, pressure and flow regulators.· Use lighters to start the flame.·Never use grease in any element of the oxygen circuit, as it may ignite.· Joints and connections will be made with appropriate fittings, duly fastened with clamps, no wire will be used.· Never leave a tube or torch inside a container, tanks or closed area, as a small leak may result in a gas explosion.· Goggles with filter Number 3 will be used.· The tubes should always be in vertical position during transport, storage and work.· Store the oxygen tubes separately from fuel gas cylinders, and also separate empty from full tubes. Identify them visibly.·The cylinders stored should be protected against falls with a chain.· Store them in well ventilated areas far from heat sources and protected from the sun.· The tubes should be transported with wheelbarrows or baskets built for that purpose. Do not lift tubes with steel slings and do not lift them from the cap. Do not roll them and do not use them as rollers.

21. COMPRESSED AIR• Use only special hoses for compressed air, able to withstandwork pressure.•Do not choke, connect or disconnect pressurized hoses. Close the valve and purge the hose before disconnecting.•All pressurized hose unions will have safety pins in their connectionsAnd safety chains, to avoid unintended disconnection.• Do not lay hoses across vehicle or people traffic areas.

36

22. FIRE PROTECTION• In every work area there will be enough fire extinguishers, according to the type of fire that may occur and have to be extinguished. They should be visible, signaled and easy to reach.• The fire extinguisher used, even partially, shouldbe reloaded.•Check periodically the expiration cards, and check if the fire

extinguisheris in good use conditions and pressurized.• Fuel recharging of pieces of equipment should be performed with motors off. If deemed appropriate, grounding should be provided to remove static charges. Avoid overflowing the tank, if this happens, collect the fuel spilled and deposit it in appropriate containers. Do not smoke during this operation.• All personnel involved in the tasks should be trained for firefightingand should know the evacuation procedures.

23. HAZARDOUS MATERIALS

•Flammable:· Fuels and flammable materials will be stored in specially designed containers and designated areas, far from any heat source and duly signaled.

•Corrosive or caustic products:· Be aware of the characteristics of the product to be handled, learn how to interpret the technical sheet.· Use the personal protection elements specific for this job, special suits, boots, gloves, masks, etc.·Have an eyewash at hand and abundant water in case of emergency.· All containers should bear a clear label with the product they contain and its characteristics.

37

24. TRAINING• All personnel involved in port area activities should be trained appropriately for the task to be developed and for the work environment. This is also applicable in case of change of task assignment.• The personnel should know the risks they are exposed to and the

prevention measuresto be taken.• The training received should be duly documented and signed by the operator, and available upon requirement of the C.G.P.B.B. The document should state topics, duration and name of the training responsible person.
