The ventilation system shall be designed to avoid stagnant areas where a hydrocarbon-rich atmosphere could collect. Are you an Engineering professional?

Higher viscosity liquids are less likely to form a mist. On any such pumps there is likely to be some small continuous vapour leak around the seal. The maximum extent of the Hazardous Area should be based on Figure 3. Join your peers on the Internet’s largest technical engineering professional community.

The hazardous area shall extend from the peripheral equipment containing hazardous fluids, using a hazard radius dependent on the Fluid Category of the fluids in the plant, as shown in the following list: 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.

The user should adapt or supplement this document to ensure compliance for the specific application. The flash point of the base oil will, therefore, be reduced. Where fluids in more than one category are present, then the most volatile of the fluids present shall be used as the basis for estimating the extent of the Hazardous Area, i. You need some real world information like the fluid, some inlet properties and outlet requirements.

On shale shakers, there can be significant gas release from associated gas which could be the major factor in estimating the air rate required. With a hazardous mud the ditch will be a primary grade source of release and therefore should preferably be in an open area.

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. The assessment of any toxic risk in the vicinity of equipment handling petroleum or other flammable fluids.


On typical open-air plant built to BP Group Recommended Practice, it is possible to simplify the classification procedure because the design features which control the boundaries are standardised. In such cases the air flow may be sufficient to allow the Zone 1 area to be classified as Zone 2. Oil-based mud in the active tanks should be ocde as hazardous, with any vents, open srea or ditches regarded as primary grade sources. It classificationn applicable to: 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 air rate required may be estimated from the information in 4. There shall be a Zone 2 area extending 7. For the purposes of area classification there is no general requirement to classify as hazardous high flash point liquids handled below the flash point.

These documents deal classificattion general principles and do not give specific guidance readily applicable to a specific situation or industry. It provides detailed guidance for petroleum fluids and for flammable fluids similar in physical characteristics to fode fluids. 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.

The clause now agrees with 5. Theoretically, the fresh oil-based mud is non-hazardous.

The following sentence shall be added: Digital Transformation may be defined in a number of different ways by analysts or classifiaction software vendors. Substitution for Are 15 5. 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 arrea day.


The local Zone 1 areas around pump seals see 5. See Quarterly Status List for contacts. Hi I am urgent need of a PDF copy of the above file, can anyne help? The hazard radius shall be 15 m for heavier than air gases, or 5 m for lighter than air gases. For lighter than air gases, the hazard radius shall be 5 m. 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. Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Substitution for IP 15 6. It is good practice to consider the mud as hazardous in the high-pressure active mud to the well system, and also in the low-pressure return system mud ditch, shale shaker and degasser.

Onshore, it is the preferred practice for classifcation tanks to be located in an open area. There should also be a written procedure to cover means of restoring ventilation. What values or data Do I need first. With an open area derrick non enclosed and an open area substructure it is good practice to classify all of the space within the derrick as Zone 2.

Each case shall be considered individually. Classificatikn is not intended to govern the type of protection of the motor, but can limit the proximity of instrumentation to the seal. Local extraction ventilation is often fitted to mud tanks in enclosed areas to improve the working environment. The recommended distances can normally be based on the solvent properties. The valve stem would thus be considered as a secondary grade of release source, unless operating experience indicates leakage is a problem.

The local ventilatin system should be of high reliability. However, coode Zone 2 Hazardous Area is often extended to readily identifiable features, e.
