Pressure Relief Systems and Process Flow Diagrams
CSP written lesson, 8 min read. CSP Domain 1: Advanced Application of Safety Principles
Written with AI help from the rules it covers, then fact-checked against them. Study aid, not site-specific safety advice. The official rule controls.
What you'll learn
- Tell a block flow diagram, a process flow diagram (PFD) and a piping and instrumentation diagram (P&ID) apart
- List the relief-system information OSHA requires in process safety information
- Explain where relief devices sit in mechanical integrity and process hazard analysis
- Calculate wetted area and emergency relief venting for an aboveground tank using 29 CFR 1910.106
What this lesson covers
This lesson covers two process safety tools the CSP blueprint names: pressure relief systems and process flow diagrams. You will learn what OSHA requires you to document about each, how to read a block flow diagram, process flow diagram and P&ID, and how to size emergency venting for a tank exposed to fire.
