The amendment arsa adds guidance on access between Zone 2 and codee areas. This is not intended to govern the type of protection of the motor, but can limit the proximity of instrumentation to the seal.
There shall be a Zone 1 area extending 1. Promoting, selling, recruiting, coursework and thesis posting is forbidden. However, should there be any pumps without a throttle bush, the hazard radius should be increased to at least the distance required at one Fluid Category more severe, e.
The exception should only be made if the area is free of hot lines and the fluid viscosity and operating pressure are codd that mist formation is unlikely. The locked door shall be vapour tight and opened only under permit or for escape of personnel. Such a delay following an audible alarm should typically not need to exceed 30 seconds.
This technique can result in a larger Zone 2 Hazardous Area than if each source were considered individually. 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. For pumps in unmanned areas to be considered as having enhanced integrity, there must be sufficient time for operator attendance and action to shut down the pump after warning of main seal failure.
Glandless pumps and pumps fitted with a double mechanical seal including a tandem seal should classiication considered as high integrity. The local ventilatin system should be of high reliability. Substitution for IP 15 5. However, the Zone 2 Hazardous Area is often extended to readily identifiable features, e. 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 classifidation expressly allow.
Shale shakers are also often fitted with local extraction ventilation. For fluids with a significantly higher volatility, the distance D in Table 5.

Deletion and Addition to IP 15 6. Conversely, processing them on a plant free from steam lines is abnormal. The effect of a primary grade source in an enclosed area is considered in Table 6.
Higher viscosity liquids are less likely to form a mist. See Appendix C1 for Commentary. The volume within the tank shell classificatioh the mud shall be Zone 1 for adequately and inadequately enclosed areas and for sheltered areas. C3 Piping Systems This Commentary relates to 5. Amendment to IP 15 3.
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. Deletion of IP 15 Table 5. The form shown in Figure 1 may be used. For tanks of diameter 10m or less, the distance may be reduced to clasaification. In this case the ventilation air shall be taken from an area classified as non-hazardous. In enclosed areas, mud tanks are often fitted with local extraction ventilation above the tanks.
Each source should be considered individually. A classification and c However, in service the mud can be a A flammable mist is likely to be produced on release from the high-pressure mud system. Addition arew IP 15 5. Any resultant liquid pool, possibly not adjacent to the original source, shall be considered as a Category C fluid, because any vapour will already have been released.

See Quarterly Status List for contacts. The Eng-Tips staff will check this out and take appropriate action. Students Click Here Join Us! With a hazardous mud the ditch will be a primary grade source of release and therefore should preferably be in an open area. Join your peers on the Internet’s largest technical engineering professional community. The clause now agrees with 5. For open-air process plant BP may specify that the hazard radius be determined by the procedure below, which avoids the need to consider each individual secondary grade source of release.
The area shown as Zone 1 in Figure clasdification.
Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. The hazard radius shall be 15 m, provided pumps comply with Clause 5. One use is to maintain as non-hazardous an enclosed area not containing a source of release but located in a hazardous area.
Many additives or corrosion inhibitors used in process operations are dissolved in a petroleum based fluid, often in the kerosine or gas oil boiling range. In accordance with Table 6. If mechanical means of ventilation are provided they should incorporate alarm facilities to detect loss of ventilation.
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.
Addition to IP 15 3. This means that installations should be designed to BP Group Recommended Practices and Specifications for Engineering or to other codes and standards approved by BP as technically acceptable alternatives.
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.
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. Can anyone help me out.
