Case Studies and Stories
Solutions to different workplace musculoskeletal disorder (MSD) hazards you can apply in your organizations.
Share your stories and case studies!
Share your success stories to help prevent MSD! Developing effective solutions can be a difficult task. With workers’ Health & Safety in mind, let’s get together and share successful interventions with each other. Whether you are a part of a company, a professional in the field or a student completing a project or placement, we are looking for case studies to showcase on the MSD Prevention Guideline for Ontario website. Let’s work together to create a robust case study database to help companies work towards preventing MSD in the workplace!
Send us your story in narrative format (less than 500 words) or download the Case Study MSD Template and let us know your experiences with preventing MSD. Please submit your story or case study to info@msdprevention.com.
