Hi,

Could you check the below paragraph please?

"The recommendations and information provided by Reference Organizations (NIOSH, OSHA) were used to design educational materials. Besides the educational sessions, some brochures were distributed among the workers, and educational posters were installed in different places where the intervention group was present. Educational sessions were held in the form of questions and answers, lectures, practices. Each session lasted for 2 hours. Educational tools included videos, PowerPoint, posters, brochures."

Thanks!
