This page provides an overview and basic descriptions of the Occupational Requirements Survey (ORS) environmental conditions elements. These requirements describe surroundings or conditions experienced by workers as they perform critical tasks in support of critical job functions.
The incidence of personal protective equipment (PPE) is identified for occupations that have exposure to hazardous contaminants; moving mechanical parts; high, exposed places; and loud noises. The duration of exposure workers have to these elements will be identified if exposure is not completely mitigated by PPE. These definitions correspond to the 2018 reference year estimates.
Job requires work outdoors with workers unprotected and exposed to the elements. This does not include the commute to/from work.
Exposure to non-weather related temperatures that are:
40 degrees or colder if the exposure is 2/3 or more of the work day
32 degrees or colder if the exposure is for less than 2/3 of the work day
Exposure to non-weather related temperatures that exceed:
85 degrees in a humid atmosphere
90 degrees in a dry atmosphere
Any non-weather related contact with water or other liquids.
Non-weather related exposure to conditions where the air contains a high amount of water or water vapor and the atmosphere is oppressive.
Exposure to a shaking object or surface that causes a strain on the body or extremities.
Exposure to a substance that negatively affects the respiratory system, eyes, skin or other living tissue via inhalation, ingestion, or contact.
Operation of or proximity to moving materials, mechanical parts, settings, or any moving objects (most commonly moving machinery or equipment) that could cause bodily harm.
Exposure to possible bodily injury from falling.
The noise intensity level to which the worker is exposed in the job:
Quiet, Moderate, Loud and Very Loud (Pictured clockwise)
