8522851.ppt - Mechanical Integrity Application

Mechanical Integrity Application

1. 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
