Geographically, Malaysia is situated in the equatorial region, thus having a climate of hot and humid throughout the
year. Effect of heat stress and physical work load at construction industry need to be investigated because of the high number of
accidents. Thus, perception of physical workload and heat stress by the construction workers in Malaysia needed to be investigated
and documented. The aim of this paper is to establish a set of questionnaires containing the item generation regarding on physical
workload and the heat stress perception of construction workers. Physical workload factors such as fatigue, risks, concentration,
work rhythm, responsibility, satisfaction, and autonomy are inserted as the items in assessing the physical workload. While heat
stress are assessed using heat risk factors such as temperature, humidity, heat radiation, air movement, workload, clothing and
acclimatisation. A questionnaire has been developed resulted from various reviewing of literatures on physical workload and heat
stress and better suited to the Malaysia working environment.
This invention is more on ergonomics scope. This ergonomics rostrum fulfills the ergonomics criteria especially

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
