The framework of this study is based on the prevention of occupational hazards among nurses.  Rosenstock‘s Health belief model was found to be suitable for this study. 

The sample size comprised of 70 nursing officers from critical and non–critical care areas. Separate code number was used for each participant. Based on the objectives, a structured knowledge questionnaire and practice questionnaire was developed to assess knowledge and practice of the nursing personnel on occupational health hazards and occupational safety measures.
