Abstract In recent years, petrochemical industry accidents occur frequently. The reason was that the existing safety measures were not comprehensive enough to protect all layers of production. It is an urgent problem for enterprises to improve the existing safety measures and form a system to cover all stages of production. Safety barrier can protect and control every layer of production, so as to protect the production process comprehensively, avoid, prevent and control accidents. Four action layers of safety barrier in petrochemical production were established, and the specific implementation method of safety barrier was proposed. This method was applied with taking atmospheric and vacuum distillation unit as an example. The results show that the atmospheric and vacuum distillation unit can be fully protected by the safety barrier through physical or non-physical means, and its safety has been significantly improved. Finally, the safety barrier database of petrochemical plant was designed and developed in order to manage the safety barrier information and make it convenient for personnel to use. The database functions include storing, querying, adding, modifying and deleting the names, categories, functions and specific description of the safety barrier.

Abstract This paper provides a specific deliberation on occupational hazards confronted daily by Malaysian Traffic Police. Traffic police is a high-risk occupation that involves a wide range of tasks and, indirectly, faced with an equally wide variety of hazards at work namely, physical, biological, psychosocial, chemical, and ergonomic hazards. Thereupon, occupational injuries, diseases, and even death are common in the field. The objective of this paper is to collate and explain the major hazards of working as Malaysian traffic police especially in Point Duty Unit, their health effects, and control measures. There are many ways in which these hazards can be minimised by ensuring that sufficient safety measures are taken such as a wireless outdoor individual exposure indicator system for the traffic police. By having this system, air monitoring among traffic police may potentially be easier and accurate. Other methods of mitigating these unfortunate events are incorporated and addressed in this paper according to the duty and needs of traffic police.

AbstractThe past 18 months have seen an unprecedented approach to vaccine development in the global effort against the COVID-19 pandemic. The process from discovery research, through clinical trials and regulatory approval often takes more than 10 years. However, the critical need to expedite vaccine availability in the pandemic has meant that new approaches to development, manufacturing, and regulation have been required: this has necessitated many stages of product development, clinical trials, and manufacturing to be undertaken in parallel at a global level. Through the development of these innovative products, the world has the best chance of finding individual, or combinations of, vaccines that will provide adequate protection for the world’s population. Despite the huge scientific and regulatory achievements and significant investment to accelerate vaccine availability, it is essential that safety measures are not compromised. Here we focus on the post regulatory approval testing by independent laboratories that provides an additional assurance of the safety and quality of a product, with an emphasis on the UK experience through the National Institute for Biological Standards and Control (NIBSC), an expert centre of the UK’s Medicines and Healthcare products Regulatory Agency (MHRA).

Background: May Measurement Month (MMM) 2020 was not officially executed globally due to the COVID-19 pandemic. But in Nepal, the MMM 2020 was conducted by following COVID-19 safety measures. Methods: We used an opportunistic screening campaign for blood pressure measurement among individuals ≥18 years in Nepal. Of the three measurements, the second and third measurements were used to estimate the mean systolic and diastolic blood pressure(BP). We defined hypertension as the systolic BP ≥ 120 or diastolic BP≥90 mmHg and or currently taking antihypertensive medicine. Results: Among the total 11,486 participants, 57%(6568/11486) were females. The mean age of the screenees was 45years(SD=17.0). The mean systolic and diastolic BP were 125.8(SD= 18.0) and 81.6(SD=10.5) respectively. About 31.3%(3592/11481) participants had hypertension. Among the hypertensive persons, 40.2%(1444/3592) were aware of their hypertension status. Among these who were aware, 79.4%(1146/1444) were taking antihypertensive medicine. However, the overall proportion of hypertensive patients taking medicine was 32.0%(1146/3592). The BP was controlled among 46% ( 527/1444) of participants who were under medication. Logistic regression analysis adjusting age, sex, body mass index(BMI), and smoking status found males, higher age groups, higher BMI, and smokers had higher odds of being hypertensive. (Figure 1) Conclusion: The results suggest a need to address the gap in awareness, diagnosis, and treatment of hypertension in Nepal. The results are limited due to the non-random participation of screenees. Figure 1. Odds ratio plot

Since the World Health Organization announced in early 2020 that the COVID-19 pandemic was accompanied by an infodemic of misinformation, we are left with the question of public perspective-driven compliance to safety measures. This preliminary study evaluated some claims about COVID-19 including vaccine conspiracy theories among Nigerians with factors influencing it. An online structured questionnaire was designed to collect one-time data from voluntary participants. Demographically, major respondents were; bachelor: 284 (75.1%), age-group between 18 and 30 years: 312 (82.5%) and male: 207 (54.8%). Those that do not know the range of infected population in the country accounted for 260 (72.2%). In opinion, 57 (15.1%) supported that SARS-COV-2 cannot survive the warm climate of African continent, and 41 (10.8%) believed the hoax theory about COVID-19. Unapproved herbal medication was reported to be used by 251 (66.4%) of the respondents while 92 (24.3%) made use of Chloroquine. For transmission related conceptions, 52 (13.8%) indicated that an asymptomatic carrier cannot spread the virus to another healthy individual. About half of the respondents 182 (48.1%) suspected that SARS-COV-2 was an engineered virus and 173 (45.8%) supported that there are underlying negative intentions on the clinical trial of COVID-19 vaccines on Africans. There is a weak correlation between the demographic data of the respondents and the claims. The level of misconception Nigerians have about COVID-19 is a major concern. Thus, it is imperative to continuously engage in community awareness and education using proven facts about the virus, and its available prophylaxis measures in order to avoid the dangers that are associated with the prevailing misconceptions.
