Abstract

PM2.5 consists of fine particles with a size of less than 2.5 micrometers, which can be easily inhaled and enter the respiratory tract, causing various health problems. Transportation plays a major role in increasing PM2.5 levels in urban areas. Some things that can be done to minimize the impact of PM2.5 are the establishment of strict air quality standards, the development of environmentally friendly technologies for industry and transportation, and increasing public awareness of the impact of air pollution on health. In addition, government policies are also needed such as the use of public transportation and greening. So that the negative impact of PM2.5 on health can be minimized and air quality can be significantly improved.

Abstract

Background: In the pharmaceutical tablet manufacturing industry, health risks involve high occupational health risks, especially in handling active pharmaceutical ingredients (APIs). This research addresses the challenge that effective risk management is essential to safeguard worker health, particularly in the production of critical products such as Non-Beta Lactams (NBL) and Penicillin. Objective: evaluating and investigating occupational health risks in the NBL and Penicillin production units, identifying key risk factors and proposing strategies to reduce exposure. Methods: This study used an observational cross-sectional design was used, focusing on environmental conditions, particulate concentrations, and compliance with personal protective equipment (PPE). The framework based on the concept of Hazard Identification and Risk Assessment (HIRA) assessed the level of risk across all stages of production, including weighing, mixing, granulation, and coating. Findings: Unit NBL indicated higher particulate levels (140 µg/m³) compared to unit Penicillin (100 µg/m³), especially during high exposure stages such as granulation, exceeding the WHO guideline (PM2.5 exposure is 25 µg/m³ for a 24-hour period) . The compliance with PPE was found to be lower in the NBL unit, which correlated with an increased incident rate. The risk assessment identified weighing and granulation as high-risk stages, requiring stricter controls. Conclusions: Reducing occupational health risks in the NBL and Penicillin units urgently requires improved engineering controls, PPE protocols and worker training. Model limitations highlight the need for enhanced risk assessment tools to improve safety outcomes.

Abstract

Longhouses in Sarawak were deeply rooted in Indigenous culture but faced significant fire risks due to their wooden structures, open-flame cooking, and poor electrical installations. This study aimed to explore fire safety knowledge, attitudes, and practices (KAP) among a longhouse community in Miri, Sarawak, Malaysia. A cross-sectional survey was conducted among 46 respondents using a 25-item questionnaire (Cronbach’s α = 0.76), and data were analyzed with the Statistical Package for the Social Sciences (SPSS). The results revealed that 61% (M = 21.39, SD = ±5.43) of respondents had good fire safety knowledge, 87% (M = 27.74, SD = ±4.77) demonstrated a positive attitude, and 63% (M = 14.72, SD = ±2.56) engaged in good fire safety practices. However, correlation analysis showed no significant relationships (p > 0.05) between knowledge and attitude (r = -0.05), knowledge and practice (r = 0.27), or attitude and practice (r = 0.11), suggesting that knowledge alone did not ensure behavioral change. Factors such as lack of training and risk perception might have influenced fire safety practices. These findings highlighted the need for targeted fire safety interventions, including hands-on training, community engagement, and improved access to fire prevention tools, and emphasized that strengthening fire safety education and policy enforcement was essential to reduce fire incidents in longhouse communities.
