Question

The threshold limit value, or TLV, of a chemical substance is________________________ A) the maximum level of a chemical to which a worker can be exposed without causing adverse health effects. B) the temperature at which a chemical will ignite. C) the amount of water needed to dilute a chemical for laboratory use. D) the amount of a chemical that can legally be stored in a laboratory.

Answer 1

The threshold limit value (TLV) of a chemical substance is the maximum level of a chemical to which a worker can be exposed without causing adverse health effects. It is an important concept in occupational health and safety.

Step-by-step explanation:

The threshold limit value, or TLV, of a chemical substance is the maximum level of a chemical to which a worker can be exposed without causing adverse health effects.

The TLV is an important concept in occupational health and safety. It is determined by considering the toxicity and other properties of the chemical, as well as the duration and frequency of exposure.

For example, the TLV for benzene is 0.5 parts per million (ppm) for an 8-hour workday. This means that a worker can be exposed to no more than 0.5 ppm of benzene in the air over an 8-hour period without risk of adverse health effects.
