SAFETY SHEET

SF6

Use and Handling


Sulphur hexafluoride (SF6) is a gas which in its basic state is colourless, odourless and tasteless. It is

not toxic, but it cannot sustain life. It is a heavy gas that is dispersed slowly into the atmosphere.

In its natural state, SF6 is delivered and stored in pressurized tanks (bottles or spheres) at a pressure

of approximately 20 bar at 20°C (in its liquid form) and complies with IEC standard 376.

However, under the effect of the electric arc, the SF6 molecules break up and the elements mostly

recombine during cooling either due to extinction of the arc or by regeneration caused by thepresence of active absorbent charges within the c ircuit breaker.

Various chemical reactions, associated with the volatilization of the materials in contact with the

electric arc, create either fluoridized or sulphurous secondary gas products or solid products in the

form of metallic fluoride powder ; or again, in the presence of traces of water or moisture,

hydrofluoric acid or sulphur dioxide.

In the life-cycle of the equipment, SF6 can be observed not only in its pure state, but also in its

contaminated state :

- the use of new SF6 for filling or adding,

- leaks under normal operating conditions,

- maintenance involving the opening of circuit breakers containing old SF6 (decomposition

products),

- abnormal conditions (internal arc fault causing the shielding to break),

- circuit breaker recycling on end of life-cycle.

WORK REQUIREMENTS.

Follow the instructions for the transport of pressurized containers.

The storage of these containers is governed by the same storage regulations as compressed gas

bottles :

- keep away from any source of heat and in a cool, dry and well-ventilated area,

- always fit a pressure reducing valve.



GRID


PS 0004EN 03 1996-03-18 2011-03-21 2 / 3


Whilst SF6 in its pure state is not toxic, the decomposition products have varying degrees of toxicity.

They may irritate the skin, the eyes and the mucous membranes; and in massive amounts may

cause serious lesions (oedema, heart failure, c irculatory disorders and unconsciousness).

However, very rapidly and before there is any real danger, signs such as a pungent smell, irritation

of the mucous of the nose, the eyes and the mouth will give a warning and the personnel

concerned will have sufficient time to take the necessary safety actions.

Where the gas is used or handled within enclosed premises, ensure adequate ventilation,especially low down.

If the gas is inhaled, the area concerned must be evacuated immediately.

Under normal operating conditions, leaks are exceptionally minor and not critical, even when the

gas contains impurities (due to the regenerating filters in the circuit breaker).

Filling and where necessary topping up operations must be carried out using the appropriate tools.

During maintenance operations, or at the end of the life-cycle, dust inside the equipment must beremoved by a vacuum extractor and the operator should wear a mask. Gas recovery must be

carried out using the appropriate gas recovery equipment.

Gases and decomposition products must be treated and/or disposed of by specialist organizations.

Under extremely abnormal conditions (e.g. break in the shielding) in an enc losed space, individual

protective equipment is recommended.

Lastly, it is forbidden to smoke, drink, eat or keep food in the vicinity of open SF6 equipment,

whether indoors or outside (harmful dust).





It is essential that both the fitter and the userread IEC Technical Report 1634 regarding the use andhandling of sulphur hexafluoride gas.

Opening On receiving a manual or electrical open order, the energy accumulated in the

operating mechanism’s opening spring (32) is freed.

The control lever (30), activated by the opening spring (32), transmits themovement to the lower pole lever (34) via the rod linkage (31), in turn movingthe moving contact (11), thus separating the contacts.

Opening

Stage 1 :

Start of opening

When tube (12) in the moving contact (11) separates from the permanent con-

tact (21), the current is routed via the arc contacts (17).

2112 1711

Stage 2 :Thermal effect

When the contacts (17) separate, an arc appears, and the energy from thisarc causes a rise in the pressure in the thermal expansion chamber (Vt),which is enclosed by the stem (24) of the fixed contact (23) and the isolating

nozzle (14).

Vt

Continued on next page.






G13--001EN024/4


Opening, continued

Stage 3 :

Breaking

When the stem (24) of the fixed contact (23) is extracted from the nozzle (14),

the thermal overpressure in the chamber (Vt) is released, which causes a jetof gas, just before the current reaches zero, which ensures the arc is com-pletely extinguished.

Simultaneously, the increase in pressure in the vicinity of the arc spreadsacross to the piston (18) exerting a force on the mobile fittings and thus reduc-ing the loading imposed on the circuit breaker’s operating mechanisms.

Vt

Stage 4 :Complete opening

The arc is extinguished.Themolecules of SF6 gas, torn apart by the arc, are instantaneously reconsti-tuted. The residual gas from the breaking is absorbed by the molecular sieve(9); a few particles are deposited as a coating of dust, which has no effect onthe circuit breaker itself.

Energy store • Closing spring 70.25 stores energy to close the circuit breaker and tocharge trip spring 70.20. Surplus energy ensures that the circuit breakercan be safely closed in all situations.

• Trip spring 70.20 furnishes the energy necessary to trip the circuit

breaker. The trip spring may be in the operating mechanism or in thecircuit breaker, depending on the circuit breaker design.

Energy storeCharging mechanism

• Motor 70.01 and gearing 79.04 serve to charge closing spring 70.25

Closing unit • On closing, the energy of closing spring 70.25 is transmitted to camdisk 70.10 via closing chain 70.26, crank lever 71.43 and closing shaft70.09. The cam disc drives main shaft 70.12 via roller lever 70.11. Thecircuit breaker is closed and trip spring 70.20 charged via drive lever70.18 and the linkage

• Cam disc 70.10 controls the travel/time characteristic of the main con-tact during closing.

Tripping unit • If trip spring 70.20 is mounted in the operating mechanism, its energy istransmitted to the circuit breaker via trip chain 70.19, main shaft 70.12and drive lever 70.18.

• The motion is retarde by trip dashpot 70.17 at the end of the trippingprocess.

Latches • When closing spring 70.25 is charged, closing latch 70.05 supports itthrough crank lever 71.43 and support pin 71.44.

• When trip spring 70.20 is charged, trip latch 70.16 supports it by thelever arm of roller lever 70.11 and main shaft 70.12.

Release device • Closing magnet 70.06 releases closing latch 70.05.

• Trip magnet 70.15 releases trip latch 70.16.




06.04.2011 48-020-212EN025/15

Auxi liaire switch • Auxiliary switch 70.21 Coupled to main shaft 70.12 serves as a refer-ence for the main contact for control, signaling and interlock functions

• When the circuit breaker is closed, one contact of auxiliary switch 70.21interrupts the closing coil circuit and thus prevents further electrical ex-citation.

• When the circuit breaker is in the tripped position, one contact of auxil-iary switch 70.21 breaks the operating release coil circuit and thus pre-vents further electrical excitation.

Motor limit switch • Motor limit switch 70.24 closes and interrupts the motor circuit. It alsoperforms interlock functions.

• While closing spring 70.25 is being charged, one contact of motor limitswitch 70.24 interupts the closing coil circuit and thus preventspremature electrical closing operation.

Mechanical clos inginterlock

• When the circuit breaker is closed, a lever coupled to main shaft 70.12disables closing latch 70.05 and prevents any further release of theclosing system.

Indicators • Circuit breaker position indicator 70.52 displays the position of the maincontact (I or O).

• Spring position indicator 70.31 displays the state (charged or dis-charged) of closing spring 70.25.

Auxi liairy devices

and tools

• Mechanical manual releases 70.07, 70.13 permit switching operations

during field service.• Hand crank 70.53 permits manual charging of closing spring 70.25.

Accessories • Cabinet to protect against weather and contact.

• Heater to prevent condensation.

• Mechanical operating counter

• Mechanical device to delay opening time (option)

• Undervoltage release (option)

• Interior lighting (option)

• Other electrical equipment as specified by customer (option).

Operating states

Note • The two illustrations below show the possible operating states andsequences of an oper ating mechanism. These are characterisedmains by the position of the circuit breaker to which the mechanism isattached, and by the position of the closing spring. The position of thespring is always linked to the position of the circuit breaker. Thepositions of the auxiliary switch and motor limit switch are importantsecondary characteristics.

• An operating mechanism remains in a steady operating state until itsposition is changed by an external control command. It can then passthrough well-defined transient (unsteady) operating states.

• Motor 70.01 starts as soon as the control voltage is imposed. It chargesclosing spring 70.25 via gearing 79.04, chain wheel 71.42, crank lever71.43 and closing chain 70.26. This process comes to an end whencrank journal 70.29 with attached closing chain 70.26 has passed top

dead point A and support pin 71.44 of crank lever 71.43 rests againstclosing latch 70.05.

• At the end of the charging process, the pair of winding levers 71.32 islifted though the (not shown) disconnecting device. Gearing 79.04 andmotor 70.01, which is shut off via motor limit switch actuating cam 70.22and motor limit switch 70.24 can now run down freely without imposingany load on closing latch 70.05.

• Motor limit switch 70.24 has now moved so as to make the closing cir-cuit, and spring position indicator 70.31 has moved to the «closingspring charged» position.

• If motor voltage drops out during the charging process, the return-stopof the pair of winding levers 71.32 keeps chain wheel 71.42 from turning

blackward and thus prevents the unwinding of closing spring 70.25.

• Circuit breaker and operating mechanism are in operating state 2

Operating state 2: steady

• Circuit breaker and operating mechanism are in operating state 2.



• Closing latch 70.05 is released by the electrical command to closingmagnet 70.06 or by actuation of mechanical manual release 70.07.

• Cam disc 70.10 turns roller lever 70.11, which follows it, in the CLOSEdirection. The circuit breaker is closed via main shaft 70.12, operatinglever 70.18 and an attached linkage. At the end of the closing move-ment, after a 60° rotation, specially designed cam disc 70.10 brings

main shaft 70.12 to a safe, low-impact stop against trip latch 70.16 viaa lever arm of roller lever 70.11. At the same time, cam disc 70.10 hasmoved away from roller lever 70.11 and the circuit breaker can be trip-ped.

• In the course of the closing movement, trip spring 70.20 is charged viatrip chain 70.19.

• The return-stop of pair of winding lever 71.32 keeps the fast gearingstages from tracking the motion during the closing operation.

• After closing shaft 70.09 has turned through approx. 180°, crank journal70.29 passes through bottom dead point B. The Kinetic energy stillpossessed by crank wheel 70.30 is returned to closing spring 70.25(recovered) via chain 70.26. By virtue of this principle, the closingmovement is brought to a gentle, impact-free stop.

• Control, indicating and interlock functions at the end of the closingmovement:

− Auxiliary switch 70.21, which is coupled to main shaft 70.12 hasmade the opening release coil circuit and broken the closing circuit.The circuit breaker can be tripped electrically, and further actuationof the closing coil is prevented.

− A lever (not shown) controlled by main shaft 70.12 has disabledclosing latch 70.05, thus mechanically preventing any further releaseof the closing system.

− Circuit breaker position indicator 70.52 has turned to the CLOSEDposition with main shaft 70.12.

Working The densimeter is fitted with two internal contacts. These contacts close suc-cessively if the gas’s density diminishes and determine 2 distinct thresholds.These contacts are wired to the terminal block inside the cubicle and are usu-ally left at the user’s disposal for the following use :

D Alarm pressure ” pae” acts as a warning (topping up necessary).

D Minimum fonctional pressure for insulation ” pme” must be used either tolock the circuit--breaker in position or to cause automatic opening. The optionis chosen by the client in keeping with operating requirements.

All the circuit--breaker’s rated performances are guaranteed up to the mini-mum specified ambient temperature andthe minimum fonctional pressure forinsulation ” pme”.

Gas pressure and density

Introduction The electrical characteristics of switchgear depend on the density of SF6 gas

i.e. the mass of gas pumped into a compartment of a given capacity.

Constanttemperature

At constant temperature, an increase of gas density results in a higher gaspressure against the walls of compartment.

Constant density At constant density, with an invariable compartment volume, the pressurechanges in the same way as the temperature. Since the gas density remainsinvariable owing to the fact that no modification occurs in the quantity of gasor the volume of the relevant compartment, the electrical characteristics of theswitchgear will remain unchanged.

Conclusion Since it is difficult to measure the gas density directly, it is essential to knowaccurately its absolute pressure and temperature.

Pressure measurement

Effective pressure ?

Absolute pressure ?

Absolute pressure = effective pressure + atmospheric pressure

Pressure Description Diagram

Effective

The pressure of SF6 gas is mea-sured by of a standard pressuregauge witha deformable diaphragmactuating an indicating pointer.One surface of the diaphragm is incontact with the SF6 gas, while theother is in contact with the atmo-sphere. The difference between thegas and the atmosphere is thus

measured, taking atmosphericpressure as a reference. This is themeasurement of the effective pres-sure of the SF6 gas.

SF6

Atmospheric pressure

Standard pressure gauge

Absolute

If the deformable diaphragm, onesurface of which is in contact withthe SF6 gas, blocks a volume wherea vacuum has been developed, thepressure gauge measures the pres-

sure difference between that of theSF6 gas and the vacuum. Since thelatter is zero, the pressure gaugemeasures the absolute pressure of the gas.The absolute pressure of the SF6

gas, independent of atmosphericpressure, reflects the quantity of gas introduced into the compart-ment and hence its density at thepresent temperature.This is measured by means of anabsolute pressure gauge which is

less generally used and more deli-cate than a effective pressuregauge. This is the reason why a ef-fective pressure gauge is used, pro-vision being made for correctionsrequired by atmospheric pressurevariations resulting from atmo-spheric disturbances and differ-ences of elevation.

Measuring density

Pressure units D The international unit pressure is the Pascal (Pa), and hectopascal (hPa)used for atmospheric pressure measurements.

D The practical unit is the bar (14.503 p.s.i.)

1 bar = 1 000 hPa = 14.5 psi1 bar = 100 kPa10 bar = 1 MPa

D Standard atmospheric pressure is equal to 1,013 hPa at sea level and anair temperature of 20°C (68°F).

Measuring density When it is not possible to directly measure density, this maybe checked usingan industrial pressure gauge capable of measuring the effective pressure.

An effective pressure value corresponds to the rated density, determined fornormal atmospheric pressure (1,013 hPa) and an ambient temperature of 20°C (68°F).For each pressure reading (filling, inspection of densimeter thresholds...), therated effective pressure should be corrected according to the ambient tem-perature and atmospheric pressure of the site at the time thereading is taken.The real pressure is therefore :

Preal = Prated effective in accordance with temperature + ΔPp *

* ΔPp : correction in accordance with atmospheric pressure.

G31--401EN021/10


Presentation

Introduction At the time of the PRE-COMMISSIONING INSPECTIONS AND TESTS,

the resistance of apparatus’ main circuit must be, necessarily, mea-sured at site.

This first measure will be used as reference to estimate the apparatus evolu-tion in the time.

The read off measures asked will be consigned in the pre-commissioning testreport by checking them with acceptance criteria, joined to the manual.

Flexible connections

Process The ALSTOM supply being restricted to the end pads of apparatus, flexible

connections and bolting hardware excluded, this manual does not give anyregulations concerning the contact resistance existing between the pads andthese connections.

However, the attention is pointed out on the importance lying with the qualityof these contacts, which depends on the assembling conditions (surfacecondition, tightening torque for screws and bolts) andhaving these conditionsmaintened times goes.For more information purposes, no total contact resistance should exceed

0.5mΩ.

Subject D This subject of this document is to describe the sequence of repair proce-dures necessary to correct any surface damage to the paint on the GCBenclosure.

D It is not in the realms of the procedure to details repair to the enclosureitself. The supervisor on site is to determine the severity of the damage to theGCB enclosure (aluminium alloy). This procedure covers damage fom smallscratch’s and scuffs. Greater damage than this would require the interventionof a site inspector.

Used products D Alcohol isopropanol.

D Paint PU780 (FARBATHANNE NF) (colour RAL 9006).

D Paintbrush.

D Emery paper.

D Not supplied : Cleaning rags, and gloves.

Process INSPECTION AND CLEAN :

D Once it has been determined that the damage is limited to only surfaceabrasion of the paint, the area of the damage will require cleaning and prepa-ration.

D Any mud, dirt orgrease must be removed from aroundthe areato berepai-

red.

D Mud and dirt can be cleaned and wiped off with wet rags and/or a sponge.Grease will need to be removed with alcohol. Once complete, leavefor a shorttime to dry. Wipe down with a clean rag.

D Use the emery paper to clean up the damaged area.

D Wipe away metal dust with a clean rag.

PAINTING :Open the pot of paint, stir if necessary, if the product has been in storage for

a long period of time.

Using the paintbrush, apply an even coat of paint over the damaged area.Paint an area slightly larger than the damaged area, covering all the surfacetouched by the emery cloth. Thus ensuring a good coverage of the exposedarea.

It have been determined that under normal circumstances one coat of paintis all that is necessary. Should the client require it a second coat of paint maybe added. To this end please refer to the details printed on the paint pot con-cerning drying times between paint applications.

I -- Introduction

During the elimination phase for a High Voltage gas insulated circuit

breaker, at the end of its service life, the quality of the treatment of wastesgenerated represents the essential environmental aspect.

This manual proposes, for each element of a High Voltage gas insulatedcircuit breaker, the recommended method of elimination for the variousmaterials it comprises, as well as any possible precautions to be taken.






G80--000EN023/6


II -- General remarks

It is necessary to proceed with a maximum amount of dismantling, so as to

ensure the best recycling possible of the materials.

Various categories of materials can be distinguished depending on thewaste processing channel followed:

DSThe SF6 gas to be recycled or reprocessed

DSThe metals to be recycled (without taking into account any surfacetreatment, paintwork or electro--silverplating)

DSWaste products to be destroyed by incineration or sent to the wastedump depending on the channel available.

DSSpecial wastes






G80--000EN024/6


III -- Categories and treatment of the materials

1 -- Treatment of

SF6 gas

The SF6 gas will be recycled in accordance with the recommendations of

the IEC 60480 Standard.

However, when recovering the SF6 gas, it is important to respect thefollowing precautions:

-- Weigh the recipients used before and after filling, so as to ensuretraceability of the weights recovered

-- For each recipient, carry out a measurement of the purity of the SF6gas and a search for the decomposition products (SO2, HF)

In case of absence of a local waste processing channel for the recycling of SF6, we recommend a return to our site in Villeurbanne, where we

propose reprocessing via our European service providers.

2 -- Materials to berecycled

Metals form the main constituent of a gas insulated substation.

The main types of metal making up a substation are:

-- Steel: steelwork structure, fasteners, electrical cubicle frames, etc.

-- Aluminium: moulded or mechanical welded enclosures, conductor bars,electrodes, etc.

-- Bolted fasteners, threaded rods, rating and name plates

-- Bare copper: electrical contacts, etc.

-- Insulated copper: electrical cable

It is important to separate these different metals when dismantling thesubstation at the end of its service life. In particular for small sub---assemblies made up of various materials.

In certain simple cases, it is sufficient to remove the fasteners ensuring theassembly and, in other cases, specific instructions shall be given.

The aluminium and copper elements must, under no circumstances,be mixed. Specific waste processing channels associated with thesematerials do not allow for perfect separation during their processing.

In cases where it is impossible to separate them, the componentmust be sent for incineration.






G80--000EN025/6


III -- Categories and treatment of the materials (contd.)

3 -- Waste products to

be destroyed byincineration

This type of waste includes the rest of the materials used in the

composition of a gas insulated substation, other than for a few veryspecific cases.

These waste products mainly include:

-- Parts in epoxy resin: insulating cone in the case of circuit breakers withinsertion resistance

-- Plastic parts loaded with glass fibre (insulating tubes, etc.)-- Seals and gaskets, rubber bands, roller bearings

-- Insulators (support or interrupting chamber) composites etc.

Where possible, we recommend that this type of waste be sent viaincineration channels with waste heat recovery.

4 -- Special wastes Certain elements, due to their function or the material constituting them,cannot be sent via a recycling or incineration channel.

They include the following components:

-- Insulating parts from the interrupting chamber

-- Absorbent molecular sieves

-- The active elements in electrical cubicles

-- Ceramic insulators (support or interrupting chamber) or those still calledporcelain, etc.

These waste products will follow specific channels and/or undergo certaintypes of processing.Precise instructions will be supplied for these types of components.

Management of SF6 gas

G80--001EN021/6


SF6 gas : Environmental impacts

Introduction The SF6 gas contributes to the greenhouse effect:

The greenhouse effect is a natural phenomena, which by capturing a part of the infra--red rays reflected from ground to space, enables the Earth to havean average temperature of 15°C.

The most abundant gases, which participate in the creation of this green-house effect are Water Vapour, Carbon Dioxide, Methane. However, since thebeginning of the industrial era, Man has released gases into the atmosphere,which artificially increase the greenhouse effect.Even if Sulphur Hexafluoride (SF6) is only present in the environment in lowlevels, it creates a greenhouse gas, which has the capacity to absorb theinfra--red rays emitted by the Earth, which is 22,200 times higher than that of Carbon Dioxide.

N.B. : 1 kg of SF6 gas emissions are, thus, the equivalent of22,200 kg of Carbon Dioxide, which corresponds to the green-house effect gas waste released by a gasoline vehicle covering120,000 km.

SF6 gas is used in High--and Medium--Voltageswitchgear for its breakingandinsulation capacities.The SF6 emissions can be generated in the equipment manufacturing, opera-ting, maintenance and decommissioning processes. The losses are, either,accidental (equipment breakage),or structural (equipment’s leaktightness).Under no circumstances, SF6 gas should be released to the environment:

N.B. : In accordance with the International Kyoto Agreements,European Regulations on fluorinated gases and IEC 62271--303applicable standards (e.g.. IEC 61634, SF6 gas handling opera-tions (filling, recovery) must be carried out by trained and quali-fied personnel, using tools and procedures enabling gas releasesto be limited.





G80--001EN022/6


SF6 gas safety rules

New SF6

D Sulphur Hexafluoride (SF6) is a colourless, odourless and non--toxic gas.

D However, it is a gas, which does not maintain life.

This gas is heavier than air and the lower parts such as trenches or cabletroughs can contain a strong concentration of this gas, which could lead toasphyxia.

N.B. : The maximum permissible concentration on a workstation,assuming that people stay there 8 hours a day, 5 days a week,is 1000 ppm (i.e. 0.1%) of the volume. This very low level is astandard value for all non--toxic gases, which are not usuallypresent in the atmosphere.

Every recipient containing new SF6 gas should be labelled as indicatedbelow:

S 7/9 – Keep container tightly c losed in a well --

ventilated place.

S 20/21 – When using, do not eat, drink or

smoke.

S 45 – In the event of an accident, contact a

doctor immediately (if possible show the doctor

this label).

S61 -- Avoid release to the environment. Refer

to special Instructions / Safety Data Sheet.

S 63 – If inhaled, move the victim out of the

contaminated area and keep them still.

S51 -- Use only in well ventilated areas.

SF6 gas safety rules (contd.)

Used SF6 D Under the influence of electrical arcing, SF6 gas can be broken down intosub--products, which are more or less toxic and/or corrosive.

D Depending on their nature, these products can be irritant for the mucousmembranes, the respiratory tracts and the skin.

The SF6 decomposition products are brought to light, even when present invery low levels, by a strong pungent and sulphur odour.

Every recipient containing used SF6 gas should be labelled:Used SF6 gas will be stored in a pressurised, leak--tight container, which mustbe resistant to decomposition products (valves, connectors and piping inclu-ded) and will be regularly inspected in accordancewith thestandards in force.The maximum quantity of polluted gas stored on site will be defined in accor-

dance with the rules in force.

S 7/9 – Keep container tightly closed in a well-- ventilated

place.

S 20/21 – When using, do not eat, drink or smoke.

S 38 – In case of insufficient ventilation, wear suitable respi-

ratory equipment.

S 45 – In the event of an accident, contact a doctor imme-

diately (if possible show the doctor this label).

S61 -- Avoid release to the environment. Refer to special

Instructions / Safety Data Sheet.

S 63 – If inhaled, move the victim out of the contaminated

area and keep them still.

S 51 -- Use only in well ventilated areas.

Evacuation of SF6 gas apparatus

Principle and

precautions

The table below gives the principle of evacuation of SF 6 gas apparatus and

precautions to take :

Step Action

1 De--energize apparatus, switch--off where applicable and earth.

2 Connect the servicing unit to the gas filling nipple by means of ahose and using an adsorber filter.

3 Remove the SF6 gas using the vacuum pump. Depending on thegas volume ; it can be stored for re--use as per indications of IECstandard.

4 Fill gas compartment if possible with nitrogen or dry compressed airat rated pressure and subsequently, discharge outdoors (if possiblethrough an adsorber filter).






G81--001EN033/4


Opening--up SF6 gas switchgear

Precautions to take At the time of the opening--up SF6 gas switchgear, take the precautions

below :

DSOpen--up SF6 switchgear only after the gas has been evacuated and thepressure inside the apparatus has been reduced to that of atmosphericpressure.

DSPut the ventilation system in operation or ensure that fresh air circulatesin some other manner when switchgear which contains decompositionproducts is opened (e.g. circuit--breaker).

DSWear suitable fresh air breathing apparatus if there is even the slightestpossibility that personnel working on the equipment could be put in dangerthrough inhalation of hazardous amounts of gas vapor from powderydecomposition products.

DSWear special overalls when working on opened--up SF6 switchgear whichcontains powdery decomposition products. After completing work removeoveralls.

DS Avoid stirring--up dust and powder from SF6 switchgear. Difficult to removedust can be removed with dry non--fibrous rags. A vacuum cleaner should beused to remove loose dust. Thevacuum cleaner filter should be able to retainsparticles of a least 1 m in size.

DS Items (such as rags, vacuum cleaner, throw--away--overalls, gloves, etc.)which come in contact with thedecomposition products must be collected andneutralized so that the dust cannot be transferred. Before getting rid of theseitems neutralize in a 3 percent soda solution for 24 hours. verify the degreeof neutralization after 24 hours. When soda is added, no bubbles should be

result. If there are bubbles repeat the neutralization.DSUnder all circumstances ensure that the decomposition products neithercome in contact with skin, eyes, clothes, nor that they are swallowed orinhaled. Pay special attention to cleanliness of body, clothes andwork--bench. Dust or powder that comes in contact with skin must be washedaway with plenty of water.It is advisable to wash face, neck, arms and hands with soap and plenty of water before work--breaks and after stoppage of work.

DS Avoid eating, drinking, smoking or storing eatables in rooms or outdoorsnear to opened SF6 switchgear which may contain arc--decomposed powder.






G81--001EN034/4


Recapitulation of important instructions

Reminder Pure, non--contaminated SF6 gas is non--poisonous. Electrical discharges

and fault--switching arcs will give rise to different grades of poisonousdecomposition products. In small amounts gaseous decomposition productsproduce -- within seconds and before any poisonous effects can take place-- warning symptoms, such as an unpleasant piercing odor, nasal, mouth andeye irritations, which enable working personnel to withdraw to safety. Soliddecomposition products (powdery residues from switching) can cause skinirritations. SF6 is about five times heavier than air, and in the absence of turbulence, results in the gas collecting just above ground level and causingsuffocation through a deficiency of oxygen.

Important

instructions

The table below recapitulates the important instructions to follow at the time

of handling of used SF6 gas and decomposition products :No. Instruction

1 As soon as an unpleasant, piercing odor from decomposition productsbecomes perceptible leave the substation room without delay. enterthe room only after thorough ventilation or when wearing suitableoxygen breathing masks (with filtering or fresh air device).

2 After disturbances, enter the substation room only after havingthoroughly aired the room or when wearing independent of ambient--air operating oxygen breathing masks, or alternatively, afterverifying by measurement that the ambient air contains at least 17%volume of oxygen, especially if, one has to reckon with theconcentration of SF6 in hazardous amounts.

3 Enter rooms located below, and connected with the substation--roomsafter thorough ventilation only, or when wearing oxygen breathingmasks which operate independent of the ambient--air, or alternatively,after having verified by measurement that the ambient air contains atleast 17% volume of oxygen.

4 Ensure that the room ventilation operates satisfactorily, whilstmaintenance work is being performed on SF6 switchgear (dischargingand filling of gas, opening and cleaning of equipment).

5 When working on opened SF6 switchgear protect skin against contactwith gas and avoid swallowing or inhaling of gas. Ensure body, clothingand work--bench cleanliness. Wear special work--overalls and aftercompletion of work discard latter.

6 Wash skin which comes in contact with powder deposits with plenty of water. Before work--breaks and after work wash face, neck, arms andhands thoroughly with soap and plenty of water.

7 Do not stir--up powder deposits resulting from arc--switching. Removesticky powder with dry rags. Use suitable vacuum cleaner withpaper--filter to remove loose powder. Discard used items andfilter--bags in such a manner that powder deposit does not spread.Before discarding neutralize used items.

8 Avoid eating, drinking and storing eatables in rooms with opened SF6

switchgear which contains powder deposits.
