Consider the following scenarios within a chemical engineering plant. For each scenario, identify whether

it pertains to personal safety or process safety $($No explanation required$)$:

a$)$ Implementing a system of double$-$checking procedures.

b$)$ Installing pressure relief valves on storage tanks to prevent over$-$pressurization and potential

explosions.

c$)$ Conducting ergonomic assessments of workstation design to minimize the risk of musculoskeletal

injuries.

d$)$ Implementing a comprehensive training program on emergency response procedures, including

evacuation protocols and first aid training.

e$)$ Developing a maintenance schedule for equipment inspections and repairs to prevent equipment

failures and process disruptions.

f$)$ Installing gas detection sensors throughout the facility to monitor for leaks and prevent the buildup of

hazardous concentrations.
