What does TLV-STEL stand for in terms of exposure limits?

The term TLV-STEL refers to "Threshold Limit Value - Short-term Exposure Limit." This designation is used to indicate the maximum concentration of a substance to which workers can be exposed for a short duration, typically 15 minutes, without suffering from any adverse health effects. TLV-STEL provides critical guidance in the field of occupational safety and health by establishing limits that help ensure worker protection during brief, but potentially hazardous exposure scenarios.

Understanding TLV-STEL is essential for Hazardous Materials Technicians as they assess risks in environments where hazardous substances are present. This knowledge helps in implementing appropriate safety measures and determining the need for personal protective equipment (PPE) or engineering controls. The significance of TLV-STEL lies in its role in maintaining workplace safety standards, thus preventing overexposure to harmful substances that could lead to acute health issues or longer-term consequences.
