Application – Identifying, Listing Equipment, and Documentation Mechanical Integrity Application – Identifying, Listing Equipment, and Documentation

Lesson Objectives Identify Types of Equipment Covered Identify Regulated Non-Process Equipment to be Covered Identify Non-Regulated, Non-Process Equipment to be Covered Describe How Equipment Information Should be Recorded and Typical Methods of Tagging Identify Equipment Documentation Required to Be in Place to be Able to Demonstrate Mechanical Integrity

Types of Process Equipment Covered Pressure Vessels and storage tanks (Interpreted by OSHA to Mean both Atmospheric and Pressurized) Piping systems (including piping components such as valves) Relief and Vent Systems and devices Emergency shutdown systems Controls (including monitoring devices and sensors, alarms and interlocks) and Pumps (Interpreted By OSHA as Applying to any Mechanical Device Moving a Fluid)

Regulated Non-Process Equipment Equipment Supporting a Regulated Process Equipment Critical to Safe Operation of Primary Processing Equipment or Controls and Limits Catastrophic Releases, e.g. Ventilation Systems Fire Suppression Systems Deluge Systems Emergency Power Systems Blast and Fire Doors Alarms and Interlocks to Detect Releases

Non-Process Exempt Equipment Cannot Contain HHC Have any Pathway to a Source Have any Controls or Relief Systems that Potentially Could Create Hazardous Conditions Be an Integrated Safety Support System for Covered Equipment

Identifying and Tagging Equipment For Each Item of Covered Equipment Document: Descriptive Name Location (Plant, Unit, Area, etc.) Manufacturer’s Name, Item Number, Serial Number Field Verify Tags Durable Paint Marking Low Stress Stamps Etched or Stamped Nameplates Metal Tags

Equipment Documentation for Mechanical Integrity Institute Document Control System for Life of Plant Initial Verification of MI Requires Proper Identification Date of Fabrication Engineering Specifications and Methods Used for Design Materials of Construction Electrical Classification Relief System Design Basis and Specifications Design Codes, Standards, and Practices Employed Current Service Much of this Can be Organized During Development of the Risk Based Inspection Program
