Table 1 shows the reliability of all the variables which are five from independent variables and one is from the
dependent variable. In this study, the first independent variable is training and supervision, the value of α is 0.802
where the no of items are 4. Next, the reliability of the second independent variable which is safe work procedure, the
value of α is 0.881 and the no of items are 7.The reliability of the third independent variable which is consultation
shows the value of α is 0.833 where the no of items are 6. Then, the reliability of the fourth independent variable
which is reporting safety, the value of α is 0.913. In this study, the no of items for management commitment is the
highest which is 8 items. The reliability of the last independent variable which is management commitment, the value
of α is 0.833. Besides that, for this research study, the reliability of the dependent variable which is injury management,
the value of α is 0.828. The most important is this variable’s alpha value is more than 0.6
