Introduction: Responder’s action during mass environmental chemical incident involves collaboration of multiple agency. They clean the exposure site, control public safety and safe lives. The health of the responder is also as valuable as the public and always been neglected. Hence, this study is to highlights the method used and challenges during the incidents. Methods: A modified Occupational Health Surveillance Programme designed by Baker and Matte (Thirteen Steps in designing and implementing an Occupational Health Surveillance Programme) was imple-mented. These method full fill the criteria of impossible further reduce exposure to known hazards and uncertain health effect of the offending chemicals. Two core workplace namely the source of chemical contamination locale and victims’ evacuation centre were identified. The exposed responder is identified and categorised according to their expected exposure. Offending chemicals identified were known hazardous to health. An electronic survey form was developed and the surveillance were conducted during the event and post-exposures of one, third and sixth months. Laboratory tests were performed as a grab sample randomly and strategically to represent responder exposure. Results: During the event, 1338 responders were surveyed and twenty percent had symptoms of cough, headache, sore throat, nausea and skin irritation. After one-month post-exposure, three percent of responder noted to have continue symptoms. Laboratory tests were performed randomly due to the sheer numbers of responders in action. Only sixty-one samples were collected and sixteen percent had positive metabolites for urine cyanide. Re-sponders with abnormal laboratory result (FBC/LFT/RP/Urine) were interviewed and a repeat sample were performed. Conclusion: The health surveillance of the responder in mass environmental chemical incident is a great challenge when the exposure level is unsure and involve more than one chemicals. Likewise, reliability and validity adopting statistical test for health surveillance instruments is unattainable due to urgency. However, a proper method of occu-pational surveillance need to be devised and implemented to ensure the protection of worker’s health is guaranteed.

Objective: Increasing amount of waste concurrently increases the risk of exposure to hazardous materials among waste collectors. Vigorous exertion in the field intensifies the abundance of contaminated inspirable droplets. If left undetected and untreated, it may provoke significant pernicious health effects and redundant burdens to employees and employers. The purpose of this study is to determine the prevalence of respiratory symptoms and their associated factors among domestic waste collectors.
Method: A cross-sectional study was conducted in Kota Kinabalu, Sabah between January and April 2020. Data were collected using a validated questionnaire which encompasses details about sociodemographic, health status, environment, and employment characteristics.
Results: A total of 290 waste collectors with a mean age of 40 (±9) years old were participated in the study. Most of them were from Kadazan-Dusun-Murut ethnic origin with educational background till secondary school. The average monthly income of the workers was USD 298.45 (±171.9) per month, and they had been in service for 11 (±9.04) years. Respiratory symptoms were seen in 21% of the workers. The identified significant risk factors were determined as underlying chronic diseases (OR=2.34; 95% CI=1.054, 5.219) and contact with pets (OR=1.87; 95% CI=1.004, 3.288).
Conclusion: Respiratory symptoms are prevalent amidst domestic waste collectors and related to their health and field activities.

An increasing amount of waste concurrently further extends the risk of exposure to hazardous material among waste collectors. In light of the COVID-19 crisis, municipal waste collectors are one of the most at-risk groups of SARS-Cov-2 exposure. Risk assessment included hazard identification, evaluation of existing control level at the workplace, estimation of likelihood and severity of hazard, risk determination, and control measure recommendations. Five waste collection activities were identified and reviewed. High-risk exposure includes collection of garbage, mechanical manipulation of compactor lorries and unloading of garbage at the disposal site. There is poor practice of personal hygiene and unestablished continuous monitoring of personal protective equipment supplies. The preventive measures in the waste collection industry are influenced by several factors. Until the preventive measures are adopted into practice and adapted according to each company's requirements, biological agents continue to be risk factor to the health workers.

Introduction: Much has been known about the psychological issues that can emerge in people who are quarantined and unable to move freely. The COVID-19 pandemic has no contrast from previous outbreaks like SARS and MERS regarding their ensuing worries and boosted anxiety levels. This article seeks to examine the unique psychological changes that occur in students who have been quarantined inside a university campus and assess sociodemographic factors associated with certain psychological factors. Methodology: The data was collected from students in an Agricultural Campus. In the first phase, the factor structure of the modified National Index Psychological Wellness (NIPW) was acceptable, and to establish statistical parameters for validation an exploratory factor analysis was done. In the second phase, Independent T-tests, ANOVA, and Hierarchical Multiple regression were performed. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) version 26.0. Result/Discussion: A total of 46 male and 76 female students enrolled in this study. The Bartlett's test of sphericity was significant (p < 0.001) and the Kaiser-Mayer-Olkin measure of sampling adequacy for the AUDIT-M was 0.901. The Cronbach's alpha of the entire modified NIPW was 0.657 which suggests reasonable internal consistency and subscales between 0.913 and 0.924. Raw scores of 12 positive items were higher for the quarantined group except for "I can do daily routines," "I understand what happens," and "I understand the action that is performed is fair." Raw mean scores of eight negative scoring items were higher in the quarantined group, except for "I feel angry" (2.88 vs. 2.89 for non-quarantined group). There were statistically significant differences between year groups for the questions "I understand what happens," "I understand the action that is performed is fair," and "I think everyone is good." Conclusion: Movement control orders or compulsory quarantine orders can be distressing and may cause understandable psychological sequelae. Holistic management of a quarantine center that addresses the needs and health of an individual student will give a positive impact on psychological wellness. Quarantining facilities can be a place of positivity, allowing people to live a shared experience together, provide peer support for each other, and give each other hope.

INTRODUCTION: Persistent exposure to indoor hazards in a healthcare setting poses a risk of SBS. This study determines the prevalence of and risk factors for SBS among healthcare workers in health clinics.
METHODS: A cross-sectional study was conducted across four health clinics from February 2022 to May 2022. As part of the study, self-administered questionnaires were completed to determine symptoms related to SBS. An indoor air quality (IAQ) assessment was conducted four times daily for fifteen minutes at five areas in each clinic (laboratory, lobby, emergency room, pharmacy, and examination room).
RESULT: Most of the areas illustrated poor air movement (<0.15 m/s), except for the laboratory. The total bacterial count (TBC) was above the standard limit in both the lobby and emergency room (>500 CFU/m3). The prevalence of SBS was 24.84% (77) among the healthcare workers at the health clinics. A significant association with SBS was noted for those working in the examination room (COR = 2.86; 95% CI = 1.31; 6.27) and those experiencing high temperature sometimes (COR = 0.25; 95% CI = 0.11; 0.55), varying temperature sometimes (COR = 0.31; 95% CI = 0.003), stuffy air sometimes (COR = 0.17; 95% CI = 0.005; 0.64), dry air sometimes (COR = 0.20; 95% CI = 0.007; 0.64), and dust sometimes (COR = 0.25; 95% CI = 0.11; 0.60) and everyday (COR = 0.34; 95% CI = 0.14; 0.81). Only healthcare workers in the examination room (AOR = 3.17; 95% CI = 1.35; 7.41) were found to have a significant risk of SBS when controlling for other variables.
CONCLUSION: SBS is prevalent among healthcare workers at health clinics.

The COVID-19 pandemic caught the world by surprise, causing millions of confirmed cases and hundreds of thousands of deaths. Hence, the Malaysian government announced a Movement Control Order at the start of the containment phase to flatten the epidemiological curve. Universiti Malaysia Sabah (UMS), a public university in Borneo, was accelerated into alert phase because of high risk of case importation from more than 400 China incoming undergraduates. Measures to mitigate the potential COVID-19 outbreaks in its population were taken by using conventional public health measures with special attention to task-shifting and widespread community mental health interventions. A Preparedness and Response Centre was established to overseer the mitigating measures happening inside the university. Measures taken included empowerment of frontline staff, strengthening of restrictions, strengthening university health center, vigorous contact tracing, widespread health education, maintaining cultural sensitivity, and establishment of early standard operating procedures and university continuity plans. Hence, UMS was able to ensure no importation of cases into its campus during both acute and containment phases at the nationwide level.
