What I Do I work in the chemical industry at a facility that makes plastic pellets: high density polyethylene, polypropylene and a polystyrene plastic known as K-Resin. The plastic pellets are sold to other companies who transform them into the plastic products we buy. My job is to help my company make the pellets safely. We study the process for making the pellets to determine high-risk scenarios, and then we determine what needs to be done to reduce the risk. If the process design cannot be changed, then I design and install safety systems, which monitor the process for unsafe conditions and shut the process down if an unsafe condition is detected.
