Fall Protection Engineering, Assessments, Equipment Installations and Training. Certification of fall protection installations by Registered Professional Structural Engineers. We are an organization of experienced and qualified fall protection engineering, safety and training professionals, dedicated to the implementation of Process Improvement (going beyond safety to uncover the roadblocks within the process that prevents employees from working safely and using safety equipment when required). With over 40 years of experience, we have trained over 25,000 managers and workers in fall protection techniques and procedures since 1970. J. Nigel Ellis has been involved with tort cases for over 20 years and over 1000 cases of very serious injury and death resulting from falls from elevation (including stairs and same level). This knowledge base has been woven into our site assessments, engineering, consulting and training courses. Dr. Ellis is a founding member of the ANSI Z359 committee that developed the new Fall Protection Code which became effective in November, 2007. Clients that have engaged DSC and EFSS to evaluate their facilities, provide engineering services and conduct fall protection training for their employees and contractors are among the Fortune 500 list. Our staff is eminently qualified in every aspect of fall protection.
