When using a laboratory hood, which statement about the volume of Class I liquids applies?

When working with laboratory hoods and Class I liquids, it is essential to follow safety regulations due to the flammable nature of these liquids. The correct statement indicates that the volume must be under 5 gallons. This limitation is in place to minimize the risk of fire and ensure proper ventilation within the hood. By restricting the volume, the likelihood of a fire hazard is reduced, and the hood can effectively ventilate any vapors generated from the liquid.

This regulation is designed to ensure that the use of Class I liquids remains safe within the laboratory environment, balancing the need for accessibility to these substances while also prioritizing safety protocols. Adhering to this guideline helps maintain a controlled space where the risks associated with flammable liquids are minimized.
