Occupational Exposure Limits

Today we are going to talk about Occupational exposure limits and all things that Many procedures generate hazardous air contaminants that can get into the air that people breath. Normally, the body can take in limited amounts of hazardous air contaminants, metabolize them and eliminate them from the body without producing harmful effects. Safe levels of exposure to many hazardous materials have been established by governmental agencies after much research in their short term (acute) and cumulative (chronic) health effects using available human exposure data (usually from industrial sources) and animal testing. When the average air concentrations repeatedly exceed certain thresholds, called exposure limits, adverse health effects are more likely to occur. Exposure limits do change with time as more research is conducted and more occupational data is collected
                 An occupational exposure limit is the maximum average air concentration that most workers can be exposed to for an 8 hour work day, 40 hour work week for a working lifetime (40 years) without experiencing significant adverse health effects. A very small percentage of individuals experience some discomfort or adverse health effects at or below the exposure limit because of a wide variation in individual sensitivities or pre-existing conditions. When employee's work a shift longer than 8 hours per day, the exposure limit must be adjusted (lowered) to prevent the employee from over exposure.

PEL’s (permissible exposure limit0 is a regulatory limit on the amount or concentration of a substance in the air. This is usually based on an eight-hour time weighted average (TWA), although some are based on short-term exposure limits (STEL).

 I find this picture very interesting. it is an easy way too calculate your permissible exposure limits. This shows that it is easy and accesible for anyone to fins out their Pel's

This picture shows that Occupational Exposure Limits is a very broad topic. There are so many topics under OEL's It's crazy to think about.
