Commodity Fumigation License Practice Exam

What does TLV stand for and what does it refer to?

1. Toxic Limit Value, levels of toxic chemicals in soil

2. Threshold Limit Value, airborne concentrations workers can be exposed to without harm

3. Technical Limit Value, safety measures for handling pesticides

4. Transport Limit Value, regulations for shipping hazardous materials

The correct answer is: Threshold Limit Value, airborne concentrations workers can be exposed to without harm

TLV stands for Threshold Limit Value. It refers to the airborne concentrations of substances, particularly chemicals, that workers can be exposed to during a typical workday without experiencing adverse health effects. TLVs are established by organizations such as the American Conference of Governmental and Industrial Hygienists (ACGIH) and are used to protect worker health by guiding regulations and safety measures in occupational settings. The concept of TLV is essential in occupational health and safety because it helps identify safe levels of exposure to various airborne contaminants. This ensures that workers remain in an environment that minimizes the risk of adverse health effects over time, promoting a safer working environment in industries where such exposures are common. The importance of TLV cannot be overstated, as it serves as a foundational guideline for employers to implement necessary safety protocols and for regulatory bodies to set occupational exposure limits.
