Purpose The purpose of this paper is to identify the facilities maintenance employees’ priority on safety management practices and relationship to safety performance. The study aims to increase the safety performance among the facilities maintenance contractor by implementing safety management practices. Design/methodology/approach The data were collected by distributing questionnaire forms to the employees of selected facilities maintenance contractors representing general workers, technicians and executive- and the management-level employees. Data were analysed using descriptive statistics, t-test, one-way analysis of variance, Pearson correlation and multiple regressions. Findings The descriptive results revealed that the employee priority on safety management practices is fairly “low”. The correlation and regression analyses tested and satisfied that management commitment, workers involvement in safety, safety training, safety communication and feedback, safety rules and procedures, and safety promotion policies significantly and strongly correlate with the degree and level of satisfaction to the safety performance. Research limitations/implications This research focuses only on facilities maintenance contractors working in the Klang Valley, Malaysia. It is possible that respondents from other areas or states may allow comparisons across different locations. Practical implications There are many factors affecting safety performance. By implementing safety management practices, high safety performance can be achieved in the facilities maintenance organisations in Malaysia. Originality/value This paper presents empirical findings on the relationship between employee priority on safety management practices elements and safety performance.

Gas Leaks

In recent years, concerns about the safety of laboratories have been caused by several serious accidents in school laboratories. Gas leaks in the laboratory are often difficult to detect and cause serious consequences. In this study, a comprehensive model based on the Bayesian network is established for the assessment of the gas leaks evolution process and consequences in school laboratories. The model can quantitatively evaluate the factors affecting the probability and consequences of gas leakage. The results show that a model is an effective tool for assessing the risk of gas leakage. Among the various factors, the unsafe behavior of personnel has the greatest impact on the probability of gas leakage, and the concentration of toxic and harmful gases is the main factor affecting the consequences of accidents. Since the probability distribution of each node is obtained based on the experience of experts, there is a deviation in the quantitative calculation of the probability of gas leakage and consequences, but does not affect the risk analysis. This study could quantitatively assess the probability and consequences of gas leakage in the laboratory, and identify vulnerabilities, which helps improve the safety management level of gas in the school laboratory and reducing the possibility of gas leakage posing a threat to personal safety.

Floating Bridges

In this paper, according to the characteristics such as great traffic throat role, obvious target and easy-to-expose, and poor protection ability of the floating bridges established in wartime and on the basis of comprehensively analyzing all risk factors affecting the floating bridges, a floating-bridge safety evaluation indexes system and a grey matter-element evaluation model 41 specific factors in the complex environment containing are established using enemy's threat, commanding decision, river environment, personnel's operation, equipment's quality, load passing and other risk factors encountered by the floating bridges as the primary indexes. Then, a safety evaluation is made in combination with a floating bridge setting-up case, thus drawing up a conclusion that the safety of this floating bridge is in a moderate state. Meanwhile, the main factors affecting the safety of the floating bridges are determined, thus providing certain references for the safety evaluation of other engineering.

Cardiovascular diseases (CVD) may be mediated through increases in the cardiovascular risk factors. Hemoglobin A1c (HbA1c) also called glycated hemoglobin is presently used for the diagnosis and management of diabetes. It has adverse effects on cardiovascular system. This review deals with its synthesis and effects on the cardiovascular system. The serum levels of HbA1c have been reported to be affected by various factors including, the lifespan of erythrocytes, factors affecting erythropoiesis, agents interfering glycation of Hb, destruction of erythrocytes, drugs that shift the formation of Hb, statins, and drugs interfering the HbA1c assay. Levels of HbA1c are positively correlated with serum glucose and advanced glycation end products ( AGE), but no correlation between AGE and serum glucose. AGE cannot replace HbA1c for the diagnosis and management of diabetes because there is no correlation of AGE with serum glucose, and because the half-life of protein with which glucose combines is only 14-20 days as compared to erythrocytes which have a half-life of 90-120 days. HbA1c is positively associated with CVD such as the carotid and coronary artery atherosclerosis, ischemic heart disease, ischemic stroke and hypertension.HbA1c induces dyslipidemia, hyperhomocysteinemia, and hypertension, and increases C-reactive protein, oxidative stress and blood viscosity that would contribute to the development of cardiovascular diseases. In conclusion, HbA1c serves as a useful marker for the diagnosis and management of diabetes. AGE cannot replace HbA1c in the diagnosis and management of diabetes. There is an association of HbA1c with CVD which be mediated through modulation of CVD risk factors.
