What does TLV-Ceiling refer to?

TLV-Ceiling refers to the maximum concentration of a substance in the air that workers can be exposed to without experiencing harmful effects. This value is particularly important because it represents a threshold that should not be surpassed at any time during the work shift. If the concentration exceeds this level, it poses a risk to workers' health, regardless of the duration of exposure.

This understanding is crucial in occupational health and safety practices to ensure that environments are maintained within safe exposure limits. By adhering to the TLV-Ceiling, employers can better protect their employees from potential acute toxic effects associated with high levels of exposure to hazardous substances.
