Occupational and Environmental Hygiene
Collaboration at Its BestThe UNC-Chapel Hill School of Dentistry value statement proclaims “passionately serving our people, our community, our field through inclusiveness and beyond excellence.” The School meets this statement through more than 117,000 annual patient visits in the three clinic settings. To meet the patient demand and move beyond excellence, the school replaced components of the vacuum system used to provide suction during dental procedures. The new equipment requires specific preventative maintenance procedures, which is the responsibility of Facilities Services. Additionally, the EPA “Dental Rule” outlines proper handling of mercury amalgam waste from dental procedures, and in 2020 will require the installation of mercury amalgam separators in the vacuum system. To meet the new challenges, the department of Environment, Health and Safety (EHS) initiated the development of a multifunctional team to address the preventative maintenance and mercury handling concerns.
The first goal was to develop a charter to provide the framework for the team’s objective and deliverables. The objective of the group is to review the use of mercury amalgams and maintenance work on the vacuum system at the School of Dentistry to ensure safe handling and proper disposal of amalgam waste and provide a safe working environment for employees. The team consists of members from Occupational and Environmental Hygiene, Workplace Safety, Chemical Safety, Facilities Services Maintenance and Facilities Services Engineering Services. The formation of the team will result in a safe work environment for employees working on the vacuum system and will ensure regulatory compliance.
To ensure a safe work environment, EHS conducted a personal protective equipment (PPE) assessment for vacuum system work to protect employees from mercury exposure until monitoring results were available. EHS adjusted the PPE requirements as monitoring results were obtained for various tasks. EHS also implemented a job safety briefing form to be completed prior to working on the vacuum system. This proactive tool provides the opportunity to discuss safety concerns and procedures, outline PPE requirements and identify hazards and controls prior to performing a specific task. EHS and Facilities Services Maintenance also collaborate on the development of job safety analyses (JSAs) for preventative maintenance activities and fine tune the JSAs once the activities are performed.
Facilities Services’ Maintenance team members provide valuable hands-on insight about the system, as they are the ones that work with the system daily. They provide feedback on the status of the system and the action items required to maintain the system for short and term goals. Engineering Services’ team members provide the technical expertise on how the system operates and improvements required for the system to function as designed.
The ultimate deliverable of the EHS and Facilities Services collaborative effort is a system description of the School of Dentistry’s vacuum system. The document will describe how the system works along with piping and instrumentation diagrams and include preventative maintenance JSAs with the proper PPE and waste disposal procedures required for the tasks. The team hopes this approach sets the precedent for establishing multifunctional teams to proactively tackle the challenges of maintaining a new system after the equipment becomes the responsibility of the University.
