BLOCK 10: ENVIRONMENTAL HEALTH II - Unit 1: Occupational and Environmental Health Site Assessment (complete) Flashcards
The key operational health tool BE uses for producing data used for health risk assessment (HRA) and to satisfy OEH surveillance requirements. It provides a standardized OEH framework for developing sampling strategies, selecting monitoring equipment, and collecting samples.
Occupational and Environmental Health Site Assessment (OEHSA)
Any environment where a potential OEH exposure may occur.
WORKPLACE
The _______________ is the heart of OEHSA, and is automatically generated through the completion of the Joint Service Occupational and Environmental Health Site Assessment (JS-OEHSA) template.
CONCEPTUAL SITE MODEL (CSM)
Six steps to the OEHSA process:
The process in which assessors visually and physically observe the site, structure(s) located on the site, and the area surrounding the site for indications of impacts or potential impacts to the environment or human health and safety.
SITE RECONNAISSANCE
Six steps to the OEHSA process:
This step is focused on considering information that is already known about a site. The objective is to identify present and past factors that could have adverse health effects on personnel.
PRE-DEPLOYMENT/BASELINE ACTIVITIES
Potential sources for this information include:
- Existing home station documentation
- Intelligence sources
- Service organizations and support agencies
- Vulnerability assessments
- Previous After Action Reports
Six steps to the OEHSA process:
Generally includes a written and graphical depiction of OEH threats and how people come into contact with the threats. The data is presented in a manner that shows the threats, exposed populations, and exposure routes.
CONCEPTUAL SITE MODEL (CSM)
Six steps to the OEHSA process:
An AOR can be large or small. It can be administrative, industrial, or all encompassing. There may be one AOR or many associated with the OEHSA. This step focuses on establishing the boundaries of the site assessment. Within this step, workplaces and AORs are delineated and similar mission activities are associated to each other.
SITE IDENTIFICATION/SECTORING
Six steps to the OEHSA process:
If changed, the data may need to be recollected and assessed.
REASSESSMENT
Six steps to the OEHSA process:
Assessments are conducted to detect or identify ambient threats or hazards that pose potential health risks. Additional sampling through specialized assessment may be required to better quantify the contaminants of concern and assess the health risk.
ROUTINE AND SPECIALIZED ASSESSMENT
This is the defining element of the OEHSA as it lists potentially and actual completed exposure pathways that personnel may/will be exposed to.
CONCEPTUAL SITE MODEL (CSM)
This will be any situation, building, or activity that releases OEH threats to exposed personnel.
SOURCE
This will be all media through which an OEH threat can travel to the member.
ENVIRONMENTAL MEDIA
Any chemical, biological, radiological, or physical OEH threat that has the potential to cause short- or long-term health effects.
HEALTH THREAT
This is the mode in which the OEH threat enters or interacts with the population at risk. Remember, from block one what routes you might be concerned with.
ROUTE OF EXPOSURE
This is known as the population at risk and is intended to capture the estimated number of personnel for that given population.
POPULATION AFFECTED
