Occupational Exposure to Resin Acids

Resin acids are terpenoid compounds (diterpenes) found in coniferous tree sap or rosin (also referred to as “pitch” or “colophony”). Rosin is formed by conifer trees and shrubs to protect and preserve wood and bark and is largely composed of a mixture of resin acids from two main classes of carboxylic acids: abietic acids (e.g., abietic acid, dehydroabietic acid, neoabietic acid, palustric acid, levopimaric acid) and pimaric acids (e.g., pimaric acid, isopimaric acid, sandaracopimaric acid).

Colden’s Favorite OSHA Letters of Interpretation (LOI): Eyewash and Shower Requirements

In 2020, exposure to harmful substances or environments accounted for 4,830 cases of eye-related injury or illness cases that resulted in at least one day away from work.

Research estimates that eighty to eighty five percent of our perception, learning, cognition and activities are mediated through vision, (Politzer, 2008).  A team of neuroscientists from MIT has found that the human brain can process entire images that the eye sees in as little as 13 milliseconds — the first evidence of such rapid processing speed. (Trafton, 2014). An eye injury can have serious implications for employees including their ability to drive, watch a game, or effectively communicate.
