Visible emissions opacity is rated on a scale from?

Visible emissions opacity is a measure used to assess the degree to which emissions obstruct light. This measurement is typically expressed as a percentage, indicating how much of the light is prevented from passing through a plume of smoke or emissions.

A scale from 0 to 100% means that 0% opacity indicates that the emissions are completely transparent, allowing all light to pass through without obstruction, while 100% opacity signifies that the emissions are completely opaque, blocking all light. This comprehensive range allows for a detailed and accurate representation of emissions visibility, which is critical for monitoring air quality and compliance with environmental regulations.

This scale is widely used in various industries, including mortuary and cemetery practices, where the management of emissions is important for adhering to environmental standards and maintaining community health.
