“Instrument Calibration on Client’s Site in Situ (or at Clients’ Workshop)”

Risk Assessment Task: - “Instrument Calibration on Site in Situ (or at Clients‟ Workshop)”

The following risk assessment has been completed to ensure adequate controls are in place to eliminate or reduce the risk to as low as is reasonably practicable.

In considering who may be harmed we have included C&P Calibration Technicians, but for each task, depending on where it takes place, then further

consideration should be given to others who may be affected by our activities e.g. other contractors.

L = Likelihood HR = Hazard Rating (with NO controls in place).

C = Consequence RR = Risk Rating (with controls in Place).

7.Objects falling from Height

5 5 25 C&P

Employees

Permanent metal toe boards on process plant working platforms and on MEWP‟s. Good housekeeping across whole plant. When working at height area below to be cordoned off by use of bunting and signage to at least 10 metres. Items secured when being transported in a MEWP basket.

Discussion to take place at Induction to prevent other workers/contractors working immediately above Calibration Technicians.

Where overhead cranes move overhead, either isolate cranes (plant to isolate or with their permission) or bellman required to alert Calibration technicians to stop work and move away from area.

2 5 10

8.Falling from Height (Working at Height) 5 5 25 C&P

Employees

Where access to Instrumentation only requires a “step up” of a few centimetres then this can be achieved on most levels. Where the need to work at height exposes the individual to a fall to danger then additional controls will need to be in place. These will involve scaffolding platforms. MEWP to be supplied and maintained to a high standard. Trained and certificated C&P operatives to operate the MEWP.

Where Instruments are at height and close to platform edges then scaffold extensions should be requested. The scaffold extensions should be erected by recognised Scaffolding Company. Stepladders with handrails and Fibre glass ladders can be used in many locations where the work is of short duration and the height to work at is relatively low, ladders can be secured or footed and supported.

2 5 10







L C RR

When working from stepladders near to platform edges and there has been NO scaffolding extensions attached to the handrail then full body fall arrest harnesses should be worn. Full body fall arrest harnesses are a last resort and should be worn in conjunction with other controls for working at height.

9.Gas / Oxygen Depletion

5 5 25 C&P

Employees

Individual gas monitors and procedures for evacuation from Process Areas. Regular Operational checks for gas leaks by trained and competent operators. Regular Planned Maintenance checks and repairs by client.

Site Inductions.

1 5 5

10.Impulse Lines /Pneumatics/Hydraulics- high pressure, corrosive chemicals

5 5 25 C&P

Employees

Where instruments involve impulse lines / pneumatics /hydraulics, they MUST be isolated prior to work commencement. Ensure isolation valves at tapping points are closed, isolate impulse lines at instrument manifold (if differential pressure ensure equalising valve is only opened AFTER closing high pressure and low pressure isolation valves and prior to opening drain valves/bleed screws. Be careful to open drain valves/bleed screws very slowly in the first instance and wear goggles and appropriate gloves whilst doing so)

Do NOT assume impulse lines / pneumatics/hydraulics have been isolated – physically check i.e. tapping point isolation valves are closed, instrument manifold valves are closed, drain valves/bleed screws are open - open drain valves/bleed screws very slowly.

17.Operating/driving MEWPS on site


Trained and competent operators holding certificate for Driving and operating MEWPS.

Equipment to be fully maintained and inspected.

Driver to use harness at all times when driving on site or when working from MEWP basket at height.

When stationary prior to work commencing outriggers must be fully deployed on solid, level ground. If ground is soft or uneven, boards are to be placed under outrigger legs.

Whilst working at height, operator is to control movement of basket from the basket and not the floor.

Operators working from basket not to over-reach or lean out of basket.

Under no circumstance are operators to exit the MEWP basket as a means of access to a place above ground level (except in an emergency). All loose equipment placed in the basket for use will be secured to ensure they cannot fall. The area around the base of a MEWP will be bunted and have cones to prevent collision from other vehicles and road users and also to prevent persons working or walking underneath.

Safe Working Procedure Final Risk Rating The risk rating for the activity of “Instrument Calibration on Client‟s Site in Situ and in Clients Workshop” has a final Risk rating of “10” if all the controls are applied at all times. Failure to implement the controls will lead to a higher risk of injury. The level of 10 is adequate (yellow section 6-15) but improvements should be made to reduce the overall risk down to acceptable (green section 1 - 5). This Risk assessment needs to be reviewed in the next 12 months (see review date). Persons and Competency All the C&P Engineering employees who calibrate instruments must have been taken through this SWP and must sign the register(on the last page of this document) to demonstrate that they understand the controls and how they are to be applied. They must be competent and have the relevant certification for the equipment they are working on. PPE Requirements The individuals are required to wear the following PPE depending on site rules and procedures. Check with the site beforehand as any/all of the following PPE may be required:- Safety Footwear with minimum 200Joules toe cap. The ankles must be protected. General purpose gloves or Kevlar gloves over surgical nitrile gloves (depending on the task). Safety helmet – centurion or equivalent Safety glasses to be worn or safety over-glasses to be worn if wearing their own prescription glasses. High visibility waistcoat. General proban treated overalls or proban treated trousers and jacket in potential fire atmospheres. Ear defenders when working in areas which require mandatory hearing protection.





In addition to the above goggles are required in plant areas instead of safety glasses and Kevlar gloves when using open blade knives, harnesses will be used when working from a MEWP basket. Some process areas may require chemical suits and this will be stipulated on the Dow Corning permit to work. NOTE:When working from stepladders near to platform edges and there has been NO scaffolding extensions attached to the handrail then full body fall arrest harnesses should be worn. Full body fall arrest harnesses are a last resort and should be worn in conjunction with other controls for working at height. Plant Status In almost all cases isolations will be required for the instrument that is to be worked on. This is most likely to be an electrical isolation, although it could be hydraulic or pneumatic isolation, depending on the type of instrument to be calibrated. Permits, Certificates or Registers A general permit to work is required for all work locations and access onto process plant. Isolations will be recorded on this permit. A separate hot work permit may be required for battery operated equipment or any specific hot work depending on the site. Access and Egress Before accessing any part of a process plant then an authorisation to work permit will be obtained from the Site permit issuing office for that particular area. Access and egress will be by recognised walkways, pavements, road crossings, working and process platforms. Access to areas where there is a risk of falling to danger will be by additional access equipment such as scaffolding, MEWP, fixed or secured and supported ladders. Procedure

1. Clearly know the address and directions to the client‟s premises.

2. Contact the process area/client representative in advance and agree that access to the specific work area is acceptable, arrange site inductions (if required), and confirm ranges of instrumentation to be calibrated.

3. Collect calibration equipment and tools required for testing at site. Ensure all calibration equipment has a current calibration certificate, is in good working order and batteries are in good condition.

4. Complete daily vehicle pre-flight check list having inspected the vehicle to take technician(s) to site.

On arrival at site premises report to the main gate for induction and site pass. Contact the client

representative to inform him you have arrived.

5. Wear the PPE that is required for the particular process area that you will be working in. N.B. There is minimum requirement as highlighted in the PPE section above for all areas. Ensure that the PPE is in good condition and affords adequate protection.

6. Report to the permit office before accessing process plant areas. Obtain a site permit to work and comply with all requirements stated and explained verbally by the issuer. Additional PPE stated must be worn. Agree access and egress routes. Agree any isolation required before commencing work.

7. Where process plant isolations are required, obtain an isolation permit from the site personnel on completion of the relevant isolation, confirming that the correct isolation has been made.

8. If a local isolation is adequate, obtain permission from site personnel prior to carrying out the isolation.





9. Where the inspection revealed working at height is a risk, then the appropriate control(s) must be adopted. We must follow the hierarchy of working at height and aim to prevent the fall in the first place i.e. permanent platform, scaffold, MEWP, stepladder with handrails on top step, harnesses.

10. Tools for use in calibration should be taken to site in a tool box, and checks need to be carried out as to the type of tool permitted by the site as some clients do not allow adjustable spanners etc. If using retractable knives then see Safety Contact on use of retractable knives.

11. At site undertake the appropriate isolation to the instrument to be calibrated. This may be electrical, pneumatic or hydraulic. Never assume that the instrument has been totally isolated. Always check prior to working on the instrument to be calibrated i.e. if electrical check there is no power to the instrument (even if low voltage it may still affect the process plant) if working on pressure systems close isolation valves / isolate impulse lines at manifold (if differential pressure ensure equalising valve is opened AFTER closing high pressure and low pressure isolation valves and prior to opening drain valves/bleed screws. Be careful to crack valves very slowly in the first instance and wear goggles whilst doing so). If removing temperature probes, know the temperature ranges and wear insulated gloves.

12. If instrument can be calibrated in situ, then this is the best option. If unable to calibrate in situ then instrument should be removed and taken back to client‟s workshop and calibrated there, before returning it to process area and re-installing.

13. Calibration Test on Site in Situ or in Clients Workshop This procedure applies to transmitting, receiving and direct reading instruments other than local pressure gauges, temperature gauges or switches

i. Check instrument at „zero‟ reading and adjust if necessary.

ii. Raise the process input signal and record the corresponding output signal and/or scale readings at 0, 25, 50, 75 and 100% of instrument range.

NOTE: The readings must always be taken when the signal is in a „rising‟ state.

iii. Lower the process input signal and again record the corresponding output signal and/or

scale reading at 100, 75, 50, 25 and 0% of the instrument range.

NOTE: The readings must always be taken when the signal is in a „falling‟ state.

iv. The percentage error calculated from the above tests shall not exceed the manufacturer‟s stated limits for accuracy and hysteresis.

v. Where necessary, adjustments shall be made according to the manufacturer‟s instructions

and the above tests repeated. Accuracy of readings must be better than or equal to the accuracy limits stated in the manufacturer‟s specification.

vi. Once an instrument has been calibrated we must demonstrate repeatability. Do not calibrate once only and assume it is correct. Repeat the test 2 or 3 times. (Remember that repeatability is often more important than accuracy).

vii. On completion of calibration local isolations can then be removed.We must NOT put the process power back on. This must be done by the plant personnel. Once this has been done there may be a requirement to vent off or bleed valves etc. Check with the process plant personnel that the instrument is reading correctly in the control room.





viii. Once the instrument has been calibrated the calibration results sheet must be completed

and signed. The instrument must also be labelled to state that it has been calibrated with a calibration sticker.

ix. A calibration certificate may be produced to sit alongside the calibration results sheet if required.

x. Records must be kept of all calibrations carried out and records made available to the client.

These records must be kept by the Client, C&P Engineering Services Ltd or both.

13.1 Pressure Gauges

i. Pressure gauges should be removed and checked by means of Hydraulic Pressure Gauge

Comparator firmly fixed to a bench. This is a means of testing a gauge against a Standard

Test Pressure Gauge. (A hydraulic dead weight tester, pneumatic calibrator, liquid filled

manometer and compressed air source may also be used depending on the gauge range

and application).

ii. Readings shall be checked for pressures corresponding to 0, 50 and 100% of the range of

the gauge under test.

iii. Actual gauge readings shall be noted for both rising and falling signals.

iv. Test gauges shall have an accuracy of or better than 0.25% of full scale and shall be

periodically checked (12 months maximum) for accuracy against a dead-weight tester.

13.2 Pressure Switches

i. Pressure switches shall be tested at their operating point using either a compressed air source or a dead-weight tester depending upon the range of the switch under test. A continuity test-circuit shall be connected across the contacts to ensure correct operation.

ii. Care should be taken to ensure that the switch operation is in the correct mode, ie. with a

rising or falling signal according to the instrument specification.

iii. Where the switching differential is stated in the specification, this shall also be checked.

13.3 Temperature Indicators (Local)

i. Local temperature indicators (dial thermometers) shall be checked using a temperature bath.

Temperature baths are generally only suitable for use in the workshop. If required for use in

the field, they must be used under cover and in a non hazardous environment.

ii. The temperature indicators (TI‟s) shall normally be checked at approximately 50% of the

range unless agreed otherwise with the client.

13.4 Temperature Switches

i. Temperature switches shall be tested at their operating point using a temperature bath. A

continuity test-circuit shall be connected across the contacts to ensure correct operation.





ii. Care shall be taken to ensure that the switch operation is in the correct mode. ie. With a

rising or falling signal according to the instrument specification.

iii. Where the switching differential is stated on the specification, this shall also be checked.

13.5 Resistance Temperature Detectors (RTD‟s)

i. Generally RTD‟s are simulated by means of a resistance decade box.

ii. For critical applications where full simulation of the operating conditions are required a

temperature bath can be used.

13.6 Thermocouples

i. Thermocouple e.m.f‟s are normally simulated by the use of a precision milli-volt signal

generating calibrator.

ii. For critical applications where full simulation of the operating conditions are required a

temperature bath can be used.

13.7 Level Switches

i. Float switches shall be tested mechanically prior to installation with a continuity test-circuit

connected across the contacts to ensure correct operation. Care shall be taken to ensure

that the switch operation mode is correct.

13.8 Solenoid Valves

i. Connect an appropriate power supply via a switch.

ii. Connect an air supply to the appropriate port or ports.

iii. Check the operation of the valve by operating the switch and observing correct changeover

action.

iv. Check the tightness of shut-off by connecting a flexible tube to the outlet port or ports and

immersing the free end in water to ensure that the valve closure is bubble-tight at the stated

design pressure.

v. Check, where applicable, electrical and manual reset, override and time delay features as

called for on the valve specification.

vi. Check that the coil resistance is correct to specification.

13.9 Flow Elements

i. Flow elements such as turbine meters, magnetic flow meters, etc., cannot usually be tested in the field and manufacturers‟ test certificates are normally accepted. Omission of tests shall be agreed with the client.





ii. Before installation, the flow element should be checked to ensure that the data and material

specification stamped on the data plate or tab handle agree with specification.

iii. Orifice plates should be examined for flatness and to ensure that they are undamaged. The bore shall be checked with vernier callipers.

14. Where an instrument cannot be calibrated either in situ or in client‟s workshop, then it should be

reported to the client for further investigation/repair.

15. Remember - On completion of calibration local isolations can then be removed.We must NOT put the process power back on. This must be done by the plant personnel. Once this has been done there may be a requirement to vent off or bleed valves etc. Check with the process plant personnel that the instrument is reading correctly in the control room.

16. Once the work is completed all tools, equipment, waste must be removed from the site.

17. Cancel the permit to work and any isolation permits and sign out of the Plant.

18. Inform the Client representative what progress has been achieved and that you are leaving site.

Hand over any documentation (calibration sheets etc) to the Client representative. If work is not completed agree a return date with the client representative.





Emergency Procedures – Telephone 3333 Internally In the event of an emergency and depending on the site and access to such, the emergency services should be called using the internal emergency number. Raising the alarm is our first priority. All C&P employees must report to their appropriate place of safety, if the alarms are sounded. You must stay at this location and report to the Client representative. Follow the directions of the Client personnel in charge at the muster point. Lifting an eye wash station or stepping on a safety shower will raise alarm to DC Control, who will send assistance to the area accordingly.

Raising the Alarm

Telephone 3333

Use your radio – Channel 15/16 call sign “DC control”

In the event where neither of the above options are possible then use safety shower or eyewash point on

plant as these will activate the alarm in DC control

Use break glass point within building for local alarm

Dow Corning Alarm Signals Klaxon 3 seconds on 3 seconds off – Major Incident All personnel to report to their nearest muster point indoors immediately. Swipe badge on Muster Reader. Fire Alarm Bells All personnel to report to their nearest fire assembly point outside immediately. Blue Flashing Light - Outside a Building No personnel to enter the building until advised by a DCL member. Audible Alarm and Red Flashing Light on Process Plant All personnel to make their work area safe and leave the area. No return until advised by a DCL Member. Note: If the last page of this document is not attached do not worry as it does not contain any relevant information regarding the SWP. The last page is a register of signatories and is intended to be detached and returned to Gorseinon head office for filing.
