AFS 2002:1Scope

Proffesional use of:- pressure equipment (PED)- certain vessels (AFS 2005:2)

Exclusion:-pressure equipment in nuclear power plant

AFS 2002:1Risk analysis

Risk analysis shall be performed before taking into operation

- finding all hazards originated from the complete installation

- definining the scope of the continous surveillance

AFS 2002:1Analysis method

Purpose Accuracy Input for review Complexity of the system Possible consequences Group´s competence Time

No prescribed method

AFS 2002:1Risk analysis

Could be performed by:

Own staff which is separated from the productionOwn staff which in another way may perform an objective assessment (preventive maintenance)Experienced consultant (own competence should be pursued)

AFS 2002:1Renewed risk analysis

Shall be performed when:

- the plant (installation) - the pressure equipment - general conditions

have been changed in a way that new hazards

may have occured or existing hazards have been

affected

AFS 2002:1Renewed risk analysis - examples

Change of safety equipment

Installation of used pressure equipment

Significantly changed operating conditions

AFS 2002:1Documents needed

According to PED: CE-marking Decalration of

conformity Instructions for use

Could be useful: Process description P & ID Lay – out drawings Risk analysis from manufacturer Detail drawings Control and safety system description Electricity drawings Spare parts list Piping and component list Safety instructions

AFS 2002:1Continous surveillance -definition

”Regular supervision of pressure equipment and safety

equipment in order to be sure that the safety is adequate”

”The goal for continous surveillance is to be reasonably assured that equipment which are inportant for safety maintain its performance and works safely”

If no remarks: Surveillance date Who preformed it (sign)

If remarks: Surveillance date Who performed it (sign) Observation Action needed Cause If cause cannot be defined, state

that Time schedule for action Date when action was taken

AFS 2002:1Documents when performing continous surveillance

AFS 2002:1Updating of program for continous surveillance

Shall be updated at least every year

If deficiencies are found, which have not been taken care of, the plant must not be used until actions have been taken. Assessment must also be performed in order to judge if routines for follow up need to be changed

Inspection by inspection body was performed Safety equipment works No leakages have occured No damages of material have occured The equipment has not been exposed to harmful outer or

inner impact No other damages or deviations have occured Known damages or deficiencies have been corrected Marking of equipment is according to the provisions Instructions for use and P&ID are updated

AFS 2002:1Continous surveillance – what inspections?

A specially appointed person shall be responsible for the work of continous surveillance.

This appointed person shall have:- understanding of the process- understanding of the pressure equipment in the plant- understanding of how the continous surveillance shall be performed

AFS 2002:1Personnel for continous surveillance

AFS 2002:1Continous surveillance of gas cylinders

Gas cylinders shall be continously looked after in order to be sure that the safety is adequate

It shall include:- visual outside inspection of the gas cylinder- visual inspection of the fittings

If damage is found, the gas cylinder shall immediately be shut off

AFS 2002:1Repair or change

Routines shall be present Written permission shall always be obtained when

performing work inside a pressure equipment If the plant or any of the equipment will change during

repair or change, the program for continous surveillance shall be adjusted

AFS 2002:1Follow up accidents and incidents

Accidents and incidents shall be documented and investigated.

Necessary action resulting from the investigation shall be taken.

Operation of the plant must not be resumed until it is established that the plant is safe

AFS 2002:1Marking of equipment

Piping and other pressure equipment shall be marked with name of fluid

All piping shall also be marked with flow direction Safety equipment shall be marked regarding function Main shut-off valves, emergency stop and its

actuators shall be marked in a way which ensures that appropriate measures can be taken quickly in an emergency

Actuators must be provided with information giving clear indications on how the equipment is operated
