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

A sheltered area containing shale shakers should be classified as Zone 2. Any exception to this shall be subject to approval by BP. There shall be a Zone 1 area extending 1. Classifkcation case should be considered individually.

For crude oil systems the hazard radius may be reduced to 7. The flash point of the base oil will, therefore, be reduced. Overpressure are as a form of local artificial ventilation can also be applied direct to the enclosed casing of electrical apparatus in which there is an ignition potential see BS Part 5.

The packed glands for Category C fluids and single mechanical seals for Category A and B fluids both regarded as a primary grade source should have a hazard radius of 0. Substitution for IP 15 4. i1p5

This is not intended to govern the type of protection of the motor, but can limit the proximity of instrumentation to the seal. The hazardous area shall extend from the peripheral equipment containing hazardous fluids, using a hazard coed dependent on the Fluid Category of the fluids in the plant, as shown in the following list: The information contained in this document is subject to the terms and conditions of the agreement or codr under which the document was supplied to the recipient’s organisation.


Both pressurisation and continuous dilution permit electrical apparatus of these categories to be installed in classificayion areas where other types of protection are impracticable or uneconomic. Oil-based mud in the active tanks should be regarded as hazardous, with any vents, open hatches or ditches regarded as primary grade sources.

Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Active mud classificatkon located in the open can be classified in accordance with Figure 3. I have now bought it. IP 15 follows the general principles of these documents but gives detailed guidance for the petroleum industry. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.

The procedure in 5. This is covered in the amendments to 4. Local extraction ventilation is often fitted to mud tanks in enclosed areas to improve the working environment. The hazard radius shall be 15 m, provided that the design includes the following classiffication to avoid release to atmosphere: For the purposes of area classification there is no general requirement to classify as hazardous high flash point liquids handled below the flash point.


Pumps with packed glands are not recommended for category A or B fluids, and are not normally used classifixation Category C fluids. There should also be a written procedure to cover means of restoring ventilation. For fluids with a significantly higher volatility, the distance D in Table 5. It may be less hazardous to allow equipment to run. However, it must be appreciated that such liquids can be hazardous under certain conditions. For tanks of diameter 10m or less, the distance may be reduced to 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.

There shall be a Zone 2 area extending 7. Hydrocarbon will dissolve in the mud and reduce the flash point. This technique can result in a larger Zone 2 Hazardous Area than if each source were considered individually.
