Occupational Alliance for Risk Science
The Occupational Alliance for Risk Science (OARS) is an initiative to facilitate sharing of information with workers and occupational health and safety professionals. OARS provides a forum for information exchange about exposure guidance for chemical stressors, methods for improving occupational risk assessments, and training opportunities. The OARS serves as the home of exposure guide values, and related guideline documents, for chemical stressors. These guide values and supporting documentation related to worker and community exposure levels for chemical and physical agents and stressors are published by the OARS. OARS is managed by Toxicology Excellence for Risk Assessment (TERA).
Second OARS WEEL for Octamethylcyclotetrasiloxane (D4) now available. The OARS-WEEL for Octamethylcyclotetrasiloxane (D4) has been posted.
Workplace Environmental Exposure Levels (WEELs)™ are health-based guide values for chemical stressors. The WEELs provide air concentrations intended to protect most workers from adverse health effects related to occupational chemical exposures.
Occupational Alliance for Risk Science Sponsorship
There are two types of sponsorship.
OARS Sponsorship: Grants intended to support the development and implementation of the Alliance mission.
WEEL Sponsorship: Grants to support the development of a WEEL for a specific chemical stressor.

OARS is a collaborative initiative with the goal of promoting worker health protection through increased access to high quality occupational exposure limits, enhancements in methods for establishing worker-health exposure guidelines, and education and training in occupational risk assessment methods.
OARS Guiding Principles
A purpose of OARS is to prioritize and recommend Workplace Environmental Exposure Levels (WEELs)™ by:
Communicating the basis for selection of candidate agents.
Harmonizing methods to obtain and analyze relevant data.
Defining a transparent process for development, approval and communication of
Sharing resources effectively among organizations.
