Are you an Engineering professional? Isolation of such equipment could cause problems and each case must be considered individually.

Area Classification to IP 15 (BP) () (RP )_百度文库

None of the information contained in this document shall be disclosed outside the recipient’s own organisation without the prior written permission of Manager, Standards, BP International Limited, unless the terms of such agreement or contract expressly allow.

Where there are adjacent non-hazardous Zone 2 and Zone 1 areas, which it is desired to keep separate by this means, then the pressure in the non-hazardous area must be classlfication than in the Zone 2 area, which must have a greater pressure than the Zone 1 area.

The tighter requirements for processing areas do take account of the fact that processing areas normally contain hot lines. Any continuous or primary grade sources shall be considered individually, together with sumps and any assessment classifivation the effect of spillage. In such cases air or an inert gas may be used and may serve other purposes also, such as a coolant for motors see also Table 7. On an operating site the responsible person could be, for example, the site Operations Manager who would be responsible for ensuring that classification was complete and updated as required.


Warning, preferably both audible and visual, should be provided for a loss of pressure differential. Substitution for IP 15 2.

There shall be a Zone 1 area extending 1. The location and number of ventilation apertures required depend on the enclosure size, shape and location relative to adjacent enclosures or obstructions. The local ventilatin system should be of high reliability.

Again each case should be considered individually. 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.

However, at the operating conditions of a typical degasser, not all of the dissolved hydrocarbon will be removed.

The use of this method is especially helpful in the early stages of design when the location of equipment features is unknown. Promoting, selling, recruiting, coursework and thesis posting is forbidden. In accordance with Table 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.

The liquid will however be at a temperature close to or at the boiling point. Theoretically, the fresh oil-based mud is non-hazardous. In such cases the air flow may be sufficient to classify the volume within the tank shell as Zone 2. Classivication this case there shall be a Zone 1 hazardous area extending 3 m horizontally classifiation vertically upwards from the ditch and vertically downwards to a solid floor, or for 9 m, whichever is less.


There shall be a Zone 1 area extending 0. The assessment flassification any toxic risk in the vicinity of equipment handling petroleum or other flammable fluids.

Red Flag This Post Please let us know here why this post is inappropriate. On high integrity and enhanced integrity pumps, there shall be no operational vents or drains, or other likely release sources for Category A or B fluids direct to atmosphere.

Hi Thanks for the post.

It’s easy to join and it’s free. The shutdown procedures should be planned to avoid the release to atmosphere of quantities larger than those considered in area classification. Classification of storage tanks should be in accordance with Chapter 3 claxsification IP 15 as clssification by this document.

With a correctly designed system with a hood the flow of air will almost certainly be sufficient to avoid classifying the volume within the tank as Zone 1.

A sheltered area containing shale shakers should be classified as Zone 2. Because the classifidation differential can drop momentarily during use of an air lock, some delay on activation of any shutdown of electric equipment may be considered. A classification and c They tend to be less specific than IP 15 and in particular do not necessarily take account of handling temperature or volatility.
