Profile bio

About Joseph Frederick

A versatile and multitalented leader within the occupational health and safety sector, I leverage deep experience in leading job safety analysis, evaluation, planning, and development to manage safety procedures in high-hazard environments. I maximize worker safety through a hands-on and proactive approach, with my greatest success being my ability to methodically manage high-pressure, unsafe incidents, and creating safe and compliant environments. In 2020, I founded Mansa in Port Tobacco, Maryland, to provide consultation for pipeline construction management, including all safety aspects of site development and oversight, restoration, asphalt, and concrete and stormwater system management. As a hands-on leader in workplace health and safety, I conduct thorough, on-site reviews overseeing all components of project life cycles to ensure infrastructure and behavioral compliance while encouraging a safety-first workplace culture. Some of my notable career achievements include: - Overseeing the review and installation of numerous stormwater management, asphalt, concrete roadway, and parking area projects; identifying and correcting potential safety issues while ensuring robust regulatory and environmental compliance. - Developing and implementing safety instructional courses to promote a culture of safety and awareness across organizations and groups while I was within the fire prevention division of Prince George’s County Fire and EMS Department. - Attaining a high-safety metric by losing zero labor hours due to injury or accident on any site I have managed or evaluated since 2014. I am always eager to grow my professional network.
