Respiratory diseases are one of the most common causes of occupational illnesses in the United States. Many occupations use personal protective equipment (PPE) in the form of respirators to protect against respiratory hazards when other control methods are not effective. However, some workers may not have had adequate training on their use. An e-learning module was developed to provide information about respirators and their use in agriculture. The interactions of matching, sorting, and review questions require the user to be an active participant with the goal of reinforcing the information. It was hypothesized the average summative assessment score would increase as the completed education level of the module users increased. It was also hypothesized the module users with previous respirator experience would have a higher average summative assessment score for the module. Outcomes were analyzed using descriptive statistics and the Kruskal-Wallis test. The latter was used compare the median summative assessment scores between gender, age, education, occupation, and respirator experience groups. The results indicated there was not a statistically significant difference between the medians of these groups. Post-module survey responses were mostly positive regarding the benefit of the E-learning module. In the future, a larger sample size with a more varied population will be needed to determine if the hypotheses are supported.
