This article provide an empirical evidence  on the validity of a questionnaire designed to assess safety leadership, as well as safety knowledge-attitude-behaviour (Safety KAB) within Malaysia’s manufacturers which fall under small and medium (S & M) entrepreneurship. The questionnaire’s items were adapted from earlier research conducted in other study contexts. First, modified fuzzy delphi method (FDM) was applied for the research to obtain expert’s consensus regarding the content validity of all items. With some modifications to suit Malaysia’s SME manufacturing setting, the  5 point Likert-scale questionnaire consisting 42 items for measuring safety leadership and safety KAB were finalised. Subsequently, it was distributed to 100 production operators from the manufacturing S& M enterrpises in the Northern Corridor Economic Region (NCER) of Malaysia for pilot testing, 95 respondents had answered. They returned the questionnaires and 89 were best to be chosen for further procedures.The determined Cronbach’s alpha values were more than 0.90 for all items representing those variables, indicating that the questionnaire possessed high reliability and internal consistency. Subsequently, exploratory factor analysis (EFA) employing principal component analysis (PCA) extraction and varimax rotation was performed to determine the construct validity.  According to the PCA results, each item was retained as all the factor loadings were above the decided cut-off value, which is 0.65. Henceforth, the questionnaire is considered valid and reliabile to be used by future researchers.

Abstract-Water is a necessity of life to humans and animals. In Malaysia, Government Link Companies (GLC) or Private Companies manages most of the water treatment plants. Chlorine gas is used as one of the water treatment media to treat raw water that will then be distributed for public or commercial usage. The large volume of Chlorine gases used and stored in these treatment plants has the potential to create a disaster if it leaks. Objective of this paper to highlight a result of Local Exhaust Ventilation (LEV) monitoring system and their performance test in controlling of air flow from the chlorine gas building to prevent leakage and spread to the surrounding environment. Methodology used follows the American Governmental Industrial Hygienist (ACGIH). The Chlorine Gas leakage system is checked and verified by using ACGIH Standard. Finally as a result, all the measured parameters (velocity, flow rate, face velocity and brake horse power (bhp)) show that the measurement and monitoring system of LEV are complied with ACGIH Standard and Local Law and Regulations.Index Terms-Chlorine gas, local exhaust ventilation (LEV), American governmental industrial hygienist (ACGIH), occupational safety and health (OSH).
