Handbook for Process Safety in Laboratories and Pilot Plants
by CCPS (Center for Chemical Process Safety)
Part 3 – Understanding Hazards and Risks
This part of the LAPP Handbook covers the two Elements in the RBPS program's Pillar II shown in Table 1‐2: Process Knowledge Management (Element 6), and Hazard Identification and Risk Analysis (HIRA) (Element 7) [7]. The purpose of these elements is to help ensure that an organization consistently develops and maintains adequate process technology information to help identify and document the:
- hazardous properties of the materials
- process design basis
- process technologies
- equipment design basis
- control and safety system design basis
- planned operating parameters
In addition, Pillar II is used to identify and document the significant process safety risks that must be managed to prevent incidents. When additional protection layers are needed, appropriate preventive and mitigative safeguards must be designed and implemented, as well.
The types of the material's hazardous properties include its physical properties, such as combustibility, flammability, chemical reactivity, toxicity, corrosivity and compatibility with various materials of construction. The process and equipment design basis includes relevant codes and standards, fabrication and installation (construction) specifications, construction records, commissioning records, equipment operating limits, engineering controls, and preventive maintenance requirements.
This part includes specific examples on how to begin implementing good practices for these elements. Process Safety Knowledge ...
