In such cases the air flow may be sufficient to classify the volume within the tank shell as Zone 2.

There should also be a written procedure to cover means of restoring ventilation. I want to size equipments such as separator, pump and valve. With a Contractor involved, the initial work will normally be carried out by the Contractor, preferably with BP involvement as the classification is developed.

Deletion of IP 15 4. All pumps are now classified in a consistent manner. These valves would normally be considered to come into the infrequently-used valve category. The lp15 shall be added to the third paragraph: Agreements reached on area classification shall be recorded formally. Close this window and log in. For lighter than air gases, the hazard classificationn shall be 5 m.

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 greater than in the Zone 2 area, which must have a greater pressure than the Zone 1 area.

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. 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.


Other valves in less onerous intermittent duties, such as remotely operated isolation valves on blending, tankage and other similar duties, or on protective instrumentation and emergency shutdown valves, are operated less frequently, say, once or less per day.

Deletion of IP 15 Table 5. There is no requirement to include details of the type of protection. Deletion and Addition to IP 15 6. Each case should be considered individually.

The clause now agrees with 5. The horizontal extent should cover the total area of the island and should extend at least 2 m from the loading arm in the parked position. Classification as Zone 1 should be considered when more than three vehicles a day unload at a specific point. There need be no hazardous area drawn from apertures in the enclosure beyond that covered by the area within which the enclosures lie.

There are also recommendations for specific definitions and requirements. The shutdown procedures should be planned clasification avoid the release to atmosphere of quantities larger than those considered in area classification.

In such a case, release is unlikely and it may be considered preferable to allow the equipment to run and thus avoid the hazards of a total emergency plant shutdown. Then you will sort of be breaking copyright law! The Eng-Tips staff will check this out and take appropriate action. Deletion of IP 15 5. If ‘in line’ outlet fans are utilised they shall be suitable for Zone 1 application.

Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Should more volatile oils be used, then it may be necessary to classify the fresh mud tanks as hazardous. Click Here to join Eng-Tips and talk with other members!


It can also be used, in conjunction with adequate ventilation, to maintain an enclosed area containing only secondary grade sources as Zone 2 when surrounded by an area classified as Zone 0 or Zone 1.

ckde Note that for this purpose, condensate shall not be regarded as crude oil. Should they be used, however, then there is likely to be a continuous weep of liquid or vapour.

The ventilation system shall be designed to avoid stagnant areas where a hydrocarbon-rich atmosphere could collect. The classlfication in 5. 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 locked door shall be vapour tight and opened only under permit or for escape of personnel.

In this Table the terms ‘high integrity’ and ‘enhanced integrity’ refer to pumps in which classiication system design reduces the probablility of release, and the likely rate of release.

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. Can anyone help adea out. The air rate required may be estimated from the information in 4. Active mud tanks located in the open can be classified in accordance with Figure 3.
