Threshold Limit Values (TLVs), often determined by the American Conference of Governmental Industrial Hygienists (ACGHI), is a key component in determining the PEL. [11] [10] Other things that contribute to determining the PEL are toxicity and particle size. [10] PELs for chemicals are measured in mg/M 3 (milligrams per cubic meter). [2]

Although there have been efforts to improve safety in work zones, fatal crashes related to construction zones have increased by 53% in California since 2010, the Caltrans Division of Research ...
The first test is called a baseline. It provides a standard to compare future audiometric tests. If a significant change in hearing capabilities occurs (called a standard threshold shift) greater steps must be taken to ensure the employee is protected from high levels of noise exposure. The third aspect is the implementation of hearing protection.
