AFS 2002:1
Use of pressureequipment
Provisions for use
AFS 2001:1
Systematic Work Environment Management
AFS 2003:3 Work in explosive environments
AFS 2006:4
Use of work equipment
AFS 2002:1
Use of pressure equipment
AFS 2002:1Use of pressure equipment
Risk analysis Continous surveillance Continous surveillance of gas cylinders Supervision of boilers Work alone Repair or change Follow up of accidents and incidents Marking of equipment
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
