| Summary: | The emergence of dust generated from the process of removal orthopedic cast materials pose a
significant potential hazardous to respiratory health among the healthcare workers (HCWs) in the
orthopedic casting room. The study was carried out to determine the total dust concentrations in the
casting room were exposed to environmental and personnel. The personnel and environmental air
sampling were conducted for 6 hours followed the standard method from NIOSH Manual of Analytical
Method 0501. Determination of personnel dust exposure were established for selected six HCWs, who
are highly risk of dust exposed based on their jobs scope in the casting room. The determination of
environmental air sampling was conducted in the casting room for six hours continuously. A set of
questionnaires was administered to evaluate the level of knowledge, attitude and practice related to
the awareness of occupational safety and health among the 43 HCWs from public hospital in Kuala
Lumpur, Malaysia. The result on total dust from the environmental air sampling (casting room) showed
mean concentration are 3.402 ± 0.003 mg/m and personal air sampling showed the mean
concentration are 5.573± 0.040 mg/m The mean total concentration obtained were below the
standard permissible exposure limit of 15 mg/m set by OSHA USA 2005. The result shows the level of
knowledge were 96.75%, attitude 83.7% and practical 82.85% among the HCWs. There are significant
relationship (p <0.05) level of knowledge with age, job titles and area of workplace. There are
significant relationships (p <0.05) level of attitudes with job titles. There are also showed a significant
relationship (p <0.05) level of practices with age, job titles and working hour per week. The potential
risk of dust exposure to the HCWs in the casting room were manageable because the dust
concentration are still low and there are adequate usage of PPE with good functioning exhaust systems
in the casting room. Most HCWs have a high level of knowledge, attitude and practical of occupational safety and health. The study showed HCWs in this study are aware of the potential hazard associated
with their workplace activities. It is the responsibility of the organization and the HCWs for providing a
healthy and safe workplace in accordance with the requirements of the Occupational Safety and Health
Act 1994 (Act 514) and relevant regulations. |
