Improving the safety of diving units by using specialized equipment

The current research was carried out with the aim of explaining the dimensions, components and items of equipment needed to improve the safety of diving units by using specialized equipment based on a mixed and applied approach with a descriptive method of exploratory-causal type. The statistical population for the interview process included experts in the field of diving at the Nadaja level, who were identified using a purposeful judgment method based on criteria, and 8 people participated in the interview process until the theoretical data saturation stage. Also, the statistical population for the distribution of the questionnaire included some commanders, diving experts in the number of 40 people who had at least 20 years of direct activity in the field of diving, and all of them were used for the distribution of the questionnaire. The data collection tool in the first stage includes the study of documents and semi-structured interviews with experts to provide a model, and in the second stage, a 20-question questionnaire for its validation, the reliability of which has been confirmed by Cronbach's alpha method. Qualitative data analysis after coding was done in three stages of data classification, processing, and judgment, and quantitative data was done using descriptive statistics. The results showed that the equipment needed to improve the safety of diving units has three dimensions: "special floating units for diving", "diving operation support equipment" and "diving operation implementation equipment" and the components and items counted are good equipment needed to improve the safety of diving units.
