This research project aims to design and fabricate a test chamber for testing Personal Protective Equipment (PPE) to ensure effective particle filtration. The chamber has a special purpose, which is to measure ultrafine and submicron particles concentration in the air and test the ergonomic design of PPE based on its effective filtration. The project also considers the environmental aspects of the chamber such as the level of noise and vibration. The chamber will be designed to measure upstream and downstream particle count. Initially, the chamber was going to be made from wood, but the research team encountered difficulties in the manufacturing process. Therefore, the chamber was redesigned to use aluminum t-slot structural brackets, which made it easier to assemble. The walls of the chamber are made of plexiglass for visibility into the chamber, and they are sealed with caulk and rubber lining. This project includes a finite element analysis of the chamber using a 200lb person in the middle and 50lb of equipment. Additionally, the functionality, sustainability, and economics of the design are analyzed. The total cost of the chamber's structure is less than $1000, and it will be compared to existing chambers based on efficacy and cost. The results of this project have the potential to be beneficial in creating sufficient ventilation and protection against harmful airborne particles in medical or heavy industrial settings. The findings can also prove invaluable in creating safer work environments for those in various industries.
