Sample interview questions: Can you provide an example of a project where you successfully mitigated a process-related safety risk in a high-volume production facility?
Sample answer:
-
Project: Mitigation of Explosion Risk in High-Volume Production of Alkyl Halides
- Objective: To reduce the risk of explosion in a facility producing alkyl halides, highly reactive and flammable compounds.
- Challenge: The main safety risk was the potential runaway reaction during the alkylation process, leading to a rapid release of heat and pressure.
- Methodology:
- Hazard Identification: Conducted a thorough hazard assessment to identify all potential hazards associated with the alkylation process.
- Risk Assessment: Evaluated the likelihood and consequences of each identified hazard.
- Risk Mitigation: Implemented various measures to mitigate the risks, including:
- Upgrading the reaction vessel with a temperature-controlled jacket and pressure relief valve.
- Installing a dedicated scrubber system to remove unreacted alkyl halide vapors.
- Implementing strict temperature monitoring and control procedures.
- Enhancing the ventilation system to ensure adequate dilution of flammable vapors.
- Providing comprehensive training to operators on safe handling and emergency response procedures.
- Outcome:
- The risk of explosion was significantly reduced, ensuring a safer working environment.
- The facility was able to continue production without any major incidents.

Project: Minimization of Toxic Emissions in Pharmaceutical Manufacturing
- Objective: To minimize the emission of toxic chemicals during the manufacturing of a pharmaceutical intermediate.
- Challenge: The process involved the use of a highly toxic solvent, which posed a health risk to workers and the environment.
- Methodology:
- Process Modification: Explored alternative re… Read full answer
