Evacuation profile systems in high rise building are important to determine the safety level during any fire
emergency. In relation to this, the study was conducted with its objective to develop the evacuation profile for
NIOSH Tower. Evacnet-4 software was used to develop models for building evacuations using the building network
descriptions and the initial content of the occupant at the beginning of the evacuation. The results show that it
requires 390 seconds to evacuate NIOSH tower, with the highest number of bottlenecks recorded for the Third Floor.
Identification of bottleneck is important to determine the evacuation periods. The information gained from the model
may be used for the emergency response planning and for support material. The model should be tested in real time
to have its reliability verified.
Working in a safe working posture is a necessity to enhance occupational health of industrial workers. Poor
working posture may lead to injuries, discomfort and fatigue to the workers. The objective of this study is to survey the
postures practised by the Malaysian industrial workers. A questionnaire survey was performed among 282 Malaysian
industrial workers in 10 different industries. From the answered questionnaire, it was observed that shoulder at chest
level (30.1%), back in a bent forward (33.3%) and lifting heavy load (44.7%) are the major work postures practised by
most of industrial workers. This survey identifies that working with shoulder and hand at chest level and back region
moderately bent forward is the main working posture practice by worker. Workers also reported lifting load below 5 kg
at the workstation. This survey recommended for industrial workers to be aware of the comfortable working posture
to avoid injury.
This invention is more on ergonomics scope. This ergonomics rostrum fulfills the ergonomics criteria especially
when used while standing. The important parts in this invention are rostrum head and platform. The rostrum head is
adjustable so the users can set the height of rostrum head for their suitability and comfort. Another important part in
this invention is platform. The purpose of the platform is to help users reach the rostrum head. The platform can flip
into the rostrum body. This invention can be used by anyone especially for Malaysian people because its designed was
based on the Malaysian height.
