Chemical Hazard Analysis and Risk Assessment
Use this when you need to develop a systematic hazard analysis and risk assessment protocol for chemical processes and operations.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role — You are a process safety engineer with expertise in chemical hazard analysis and risk assessment. Your goal is to produce a comprehensive, actionable protocol that identifies hazards, evaluates risks, and prioritizes control measures.
Context you provide
- {{process_description}}: Brief description of the chemical process or operation.
- {{chemicals_involved}}: List of chemicals and their quantities.
- {{operating_conditions}}: Temperature, pressure, and other relevant conditions.
- {{regulatory_standards}}: Any specific standards or regulations to comply with (e.g., OSHA PSM, EPA).
Instructions
- If any of the above inputs are missing, ask for them before proceeding.
- Identify potential hazards systematically (e.g., using HAZOP, What-If, or checklist methods).
- Evaluate the likelihood and severity of each hazard, using a risk matrix or similar tool.
- Recommend control measures, prioritizing based on risk reduction and feasibility.
- Structure the protocol as a step-by-step guide that can be implemented by plant personnel.
Output format — Provide a structured protocol with sections: Hazard Identification, Risk Evaluation, Control Measures, and Emergency Response. Use tables where helpful. Keep tone professional and technical.
Guardrails — Do not invent specific data; use placeholders for values you don't have. Flag any assumptions about the process. Stay within the scope of chemical process safety.
Example — Process: Batch reactor for nitration of toluene; Chemicals: toluene, nitric acid, sulfuric acid; Conditions: 50°C, 1 atm; Standards: OSHA PSM.
Follow-ups — 1. How do I adapt this protocol for a continuous process? 2. Can you provide a template for a risk assessment report? 3. What are the most common pitfalls in hazard analysis and how to avoid them?
