This document provides an introduction and overview of HAZOP (Hazard and Operability) analysis. It discusses that HAZOP is a systematic approach to identifying hazards and deviations from design parameters like flow, temperature, and pressure. The objectives of HAZOP are to investigate potential deviations from design intent and their causes, consequences, safeguards, and recommended actions. An example HAZOP analysis is provided to illustrate the methodology. Key advantages of HAZOP include improving safety and identifying imaginative risks and operability issues. Recent major accidents in the pharmaceutical industry are also briefly mentioned.
INTRODUCTION & BASIS OF HAZOP
- 2. INTRODUCTION & BASIS OF HAZOP (Hazard and Operability) Hazards Identification During Operation
- 3. Objective Of The Presentation • Give the knowledge or an understanding of analysis and training in how to apply their abilities to improve human • Give an understanding about adequate safeguard (existing setup/new design) to control the risk.
- 4. Agenda • What is HAZOP • The main purpose/objectives. • Advantages of HAZOP • The basic concept • Methodology • Examples
- 5. What is “HAZOP” ? • Hazards and operability are a systematic, logical approach to determining hazards. • Hazards; which is defined as ”deviation” within parameters that may have dangerous ”consequences”. • The parameters are; flow, temperature, pressure etc. • HAZOP is a team work, people representing from different parts in a plant. • HAZOP is basically for safety.
- 6. Purpose of the HAZOP • To investigate how the system or plant deviate from the design intent. • Create risk for personnel and equipment and operability problems.
- 7. Objectives of HAZOP • Any perceived DEVIATIONS from intended design/operation. • The CAUSES for those deviations • The CONSEQUENCES of those perceived deviations. • SAFEGUARDS to prevent causes and mitigate consequences of the perceived deviation. • Recommend ACTIONS in design and operation to improve safety and operability of the plant
- 10. HAZOP Example
- 11. HAZOP Example • Deviation: Keyword being applied is FLOW/NO. • Cause: Potential causes that would result in deviation is the strainer ”S” blockage due to impurities in the dosing tank T might cause No Flow. • Consequences: Loss of dosing results incomplete reaction in V • Safeguard: Local pressure gauge in discharge from pump might indicate problem was arising". • Action: Fit a differential pressure gauge across the strainer, with perhaps a high dP alarm to give clear indication that a total blockage is imminent.
- 12. ADVANTAGES OF HAZOP • It gives the design ideas with imaginative anticipation of deviations. • HAZOP methodology is widely used to aid LOSS PREVENTION. • Can be used almost all operations in process industries. • No special level of academic qualification is required to perform HAZOP.
- 13. Major accidents/hazards in pharmaceutical plants/companies in recent years • In 2012, there were 3 fatalities and 18 injuries from an explosion at Neptune Technologies. There was 1 death and 8 injuries at Teva Croatia. •In 2012, there was an explosion at an API plant in Punjab causing 4 deaths and 17 injuries. •In 2013, Amgen had an flammable explosion that injured two workers at their South San Francisco branch. Sandoz had a fire which caused major drug shortages but no one got hurt.
- 16. Always Remember! • A single hazard could potentially lead to multiple forms of harm
