Question

Threshold Limit Values - Short Term Exposure Limits (TLV-STEL) is designed to protect workers from.

A) Chronic exposure to toxic chemicals
B) Acute, brief exposure to high concentrations of chemicals
C) Skin contact with hazardous materials
D) Prolonged exposure to low levels of chemicals

Answer 1

Threshold Limit Values - Short Term Exposure Limits (TLV-STEL) protect workers from acute, high levels of chemical exposure. The guidelines are crucial for preventing immediate health effects from brief exposure to toxic substances in occupational settings.

Step-by-step explanation:

The Threshold Limit Values - Short Term Exposure Limits (TLV-STEL) are designed to protect workers from B) Acute, brief exposure to high concentrations of chemicals. These guidelines are critical for ensuring safety in occupational settings where there is potential for sudden exposure to toxic substances. Unlike chronic exposure, which occurs over an extended period, acute exposure refers to a high level of contact with a chemical for a short duration. Understanding and adhering to TLV-STEL is essential for preventing immediate and severe health effects that can result from such exposures.
