Text in italics is Commentary. Fixed roof tanks with a nitrogen blanket and i;15 to atmosphere shall be classed as a primary grade source of release. The resulting Zone 1 should extend vertically from the island base to 2 m above the walkway.

The form shown in Figure 1 may be used. The following sentence shall be added: The clause now agrees with 5. Theoretically, the fresh oil-based mud is non-hazardous. Amendment to IP 15 Figure 3. Higher viscosity liquids are less likely to form a mist. A vent or drain to atmosphere which is blanked in normal operation and used only on depressured shut-down equipment should not be regarded as an operational vent or drain.

It does not cover: Deletion and Addition to IP 15 6. Equipment in the enclosure will, by definition, be suitable for use in Zone 2 and therefore suitable for short term use in a flammable atmosphere.


However, the Zone 2 Hazardous Area is often extended to readily identifiable features, e. On shale shakers, there can be significant gas release from associated gas which could be the major factor in estimating the air rate required. In this Table the terms ‘high integrity’ and ‘enhanced integrity’ refer to pumps in which the system design reduces the probablility of release, and the likely rate of release.

The Eng-Tips staff will check this out i;15 take appropriate action. Offshore and in onshore areas with severe weather conditions this can be impracticable.

Warning of main seal failure is therefore required. Thanks for your link JL Seagull.

However, the principles of this document may be used classiication discretion to guide the location of non electrical ignition sources. Active mud tanks located in the open can be classified in accordance with Figure 3. The use of this method is especially helpful in the early stages of design when the location of equipment features is unknown. BP Group RP recommends seal types for specific applications.

Pumps in continuously manned areas, with single mechanical seal, throttle bush and either a back-up or lip seal will normally be regarded as classificarion enchanced integrity.


These valves would normally be considered to come into the infrequently-used valve category. For gases or Category A and B fluids, the size of the Hazardous Area will normally be determined by the initial vapour release. 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.

To reduce the extent of the Hazardous Area from tanks located within a module, a local artificial ventilation extraction system should be used.

Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. All pumps are now classified in a consistent manner.

The assessment of any toxic risk in the vicinity of equipment handling petroleum or other flammable fluids. In this case the ventilation air shall be taken from an area classified as non-hazardous. The amendment also adds guidance on access between Zone 2 and non-hazardous areas. Substitution for IP 15 1.
