| dc.description.abstract | Majority of the respirator used in Malaysian industries are imported from America. Therefore the facial characteristics of Malaysian were not considered in the design process. Thus, leakages may occur when respirator does not fit users. This study aims to develop a prototype of a half-mask respirator using some new techniques. Facial anthrophometric data collection was conducted based on 47 samples of Malaysian Malay males. Statistical method was applied to establish design information from the data. Reverse engineering was utilized to make the mock-up part of the respirator from the face model using clay modeling. 3D scanner was used to digitize the mock-up part. Then, the digital model was prototyped by FDM machine. It was found that there were some differences in measured anthropometric data of this work to that of the American, where the Malays have relatively wider nose and lip length while the American has bigger face shape and narrower nose compared to that of the Malays. Four different sizes (small, medium, large and extra large) of respirators were determined using statistical method. The study showed that, American designed respirator products are not suitable for Malaysian. Therefore, the current work also established an applied technique for respirator product development based on anthropometric data, RE and RP. A simple verification test of the sample model on Malay subjects shows that the average leakage percentage was 21%. Future research is suggested to extend the data collection with larger sample size by using randomized sampling techniques and completing the final prototype with real material for fit performance test purposes. | en_US |
