This paper describes the development of U.S. Army Public Health Command (Provisional) Technical Guide 312, Health Risk Assessment Methods and Screening Levels for Evaluating Office Worker Exposures to Contaminants on Indoor Surfaces Using Surface Wipe Data. Surface sampling of indoor surfaces may be performed to determine whether a building is safe for re-entry following an event (for example, fire, pesticide application) or change in building use (for example, laboratory to administrative office). Surface wipe sampling results may be used to assess either the degree of contamination before cleanup or to determine whether post-abatement (also post-remediation, post-clearance) actions were effective. The U.S. Army Public Health Command (Provisional) Environmental Health Risk Assessment Program has conducted risk assessments based on surface wipe sampling data and, over time, has evolved the methodology into a technical guide. The technical guide addresses the need to develop an approach to characterize potential health risk to exposed populations using surface wipe sampling results and to provide surface wipe screening levels to facilitate initial assessments. The methodology provides a means to estimate office worker exposures from inhalation of resuspended particles, dermal contact, and incidental ingestion exposure routes. Potential chemical health risks from aggregated intakes are evaluated using conventional U.S. Environmental Protection Agency risk assessment methods.

During the 1970s, the Army health hazard assessment (HHA) process developed as a medical program to minimize hazards in military materiel during the development process. The HHA Program characterizes health hazards that soldiers and civilians may encounter as they interact with military weapons and equipment. Thus, it is a resource for medical planners and advisors to use that can identify and estimate potential hazards that soldiers may encounter as they train and conduct missions. The U.S. Army Center for Health Promotion and Preventive Medicine administers the program, which is integrated with the Army's Manpower and Personnel Integration program. As the HHA Program has matured, an electronic database has been developed to record and monitor the health hazards associated with military equipment and systems. The current database tracks the results of HHAs and provides reporting designed to assist the HHA Program manager in daily activities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
