The dimensions shown in IP 15 Figure 3. The local Zone 1 areas around pump seals see 5. The hazardous area shall extend from the peripheral equipment containing hazardous fluids, using a hazard radius dependent on the Fluid Category of the fluids in the plant, as shown in the following list: Glandless pumps and pumps fitted with a double instithte seal including a tandem seal should be considered as high integrity.
A sheltered area containing shale shakers should be classified as Zone 2.
The more volatile components are likely to be removed in the degasser and also the mud will tend to cool in storage. Further guidance is also contained in BS and Active mud tanks located in the open can be classified in accordance with Figure 3.
For the purposes of area classification there is no general requirement to classify as hazardous high flash point liquids handled below the flash point. Substitution for IP 15 6. Deletion and Addition to IP 15 6. I have now bought it. Where is the project destination?
This is not intended to govern the type of protection of the motor, but can limit the proximity of instrumentation to the seal. If access exists between an external Zone 1 and an overpressure protected non-hazardous area, then an air lock shall be installed to prevent direct connection.
Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. Feedback and Further Information Users are invited to feed back any comments and detail experiences in the application of BP RPSEs to assist in the process of their continuous improvement. It is not capable of assessment by simple rules for all situations and therefore this practice refers the user to a ventilation specialist. The form shown in Figure 1 may be used. Then you will sort of be breaking copyright law!
Because the pressure differential can drop momentarily during use of an air lock, some delay on activation of any shutdown of electric equipment may be considered. Hence it is acceptable to use air drawn from a Zone 2 area. Each case should be considered individually.
In many offshore installations more stringent precautions may be necessary and reference to BP Group RP to should be made for each application. It is applicable to: BP may specify an exception to this if it can be confirmed that the liquid cannot be atomised or raised above the flash point on release.

Overpressure protection as a form of local artificial ventilation can also be applied direct to the enclosed casing of electrical apparatus in which there is an ip115 potential see BS Part 5. One use is to maintain as non-hazardous an enclosed area not containing a source of release but located in a hazardous area. The clause now agrees with 5. I thought pf was a free document. The work, which requires an interdisciplinary approach, should be carried out by engineers who have knowledge of the process systems and equipment, in consultation with safety and electrical engineering personnel as appropriate.
The exception should only be made if the area is free of hot lines and petrpleum fluid viscosity and operating pressure are such that mist formation is unlikely.
Addition to IP 15 6. Oil-based mud in the active tanks should be regarded as hazardous, with any vents, open hatches or ditches regarded as primary grade sources. Such conditions are unlikely and there is no indication from operations that classification of hydraulic system is necessary.
Substitution for to IP 15 1. Both pressurisation and continuous dilution permit electrical apparatus of these categories to be installed in hazardous areas where other types of protection are impracticable or uneconomic. Substitution in IP 15 6. Substitution for IP 15 1. Pumps in continuously manned areas, with single mechanical seal, throttle bush and either a back-up or lip seal will normally be regarded as having enchanced integrity.

Should more volatile oils be used, then it may be necessary to classify the fresh mud tanks as hazardous. Pf roof tanks with a nitrogen blanket and venting to atmosphere shall be classed as a primary grade source of release. The remaining area within the module can be considered as Zone 2. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
Text in italics is Commentary. Warning, preferably both audible and visual, should be provided for a loss of pressure differential. Are you an Engineering professional? C3 Piping Systems This Commentary relates to 5. The pressure of 5 bar g is probably the minimum required to produce a mist with a low viscosity oil.
In this application the ventilation air may be drawn from an area classified as Zone 2 or as non-hazardous.
