Attachment: Purpose Code Definitions

Code Description

* Assigned to paragraphs that require the Owner's Engineer to provide additional information or make a decision.

A Assigned to paragraphs that require approval from the Owner's Engineer before the work may proceed or the design is finalized.

C Assigned to paragraphs whose primary purpose is reduced costs. Reduced cost in this context refers to initial investment cost and does not include life cycle cost considerations. Life cycle cost considerations are captured under reliability, maintainability, or operability purpose codes.

E Assigned to paragraphs whose primary purpose is driven by environmental considerations. Environmental considerations typically include specifications intended to protect against emissions/leakage to the air, water, and/or soil. Deviations from the specifications contained in such paragraphs require formal review and approval according to local environmental policy.

I Assigned to paragraphs that provide only clarifying information, such as Scope statements, definitions of terms, etc.

M Assigned to paragraphs whose primary purpose is to provide for maintainability of equipment or systems. Maintainability provisions are those that facilitate the performance of maintenance on equipment/systems either during downtimes or during onstream operations.

O Assigned to paragraphs whose primary purpose is to assure operability of equipment or systems. Operability is the ability of the equipment/system to perform satisfactorily even though conditions are off-design, such as during start-ups, process swings, subcomponent malfunction, etc.

R Assigned to paragraphs whose primary purpose is to improve or assure the reliability of equipment or systems. Reliability is a measure of the ability of equipment/systems to operate without malfunction or failure between planned maintenance interventions.

S Assigned to paragraphs containing specifications/guidance where the primary purpose is the avoidance of incidents impacting personnel safety, operational safety, and the public in general and/or involving responses to emergency situations. Any deviation from the specifications contained in such designated paragraphs requires formal review and approval according to local safety policy.

Personnel Safety: Refers to incident-related personnel injuries or illness, e.g., burns, cuts, abrasions, inhalation of or exposure to dangerous substances, etc., that could result in medical treatment, restricted work, lost-time incidents, or fatalities.

Operational Safety:

Refers to the prevention and control of process releases, fires, and/or explosions that could result in damage to equipment, process disruption, or personnel injury or illness.
