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

2. 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

3. 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)

4. 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

5. 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

6. 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

7. 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
