American Chemical Society (ACS) Laboratory Safety Practice Test

True or False: Safety regulations allow the use of contact lenses in the laboratory at any time.

1. True

2. False

3. Only during low-pressure work

4. Sometimes, depending on the chemicals

The correct answer is: False

In laboratory environments, safety regulations generally recommend against the use of contact lenses due to the potential risks they pose. When working with hazardous or volatile chemicals, contact lenses can trap harmful substances against the eye, increasing the risk of irritation or injury. Moreover, if an accident occurs that results in a chemical splash, contact lenses can hinder effective rinsing of the eyes, which is critical for safety in such circumstances. Therefore, the guidance in laboratory settings is typically to use safety goggles instead, as they provide better protection against chemical exposure. This aligns with standard safety protocols that prioritize eye protection and minimize risks associated with contact lenses in the face of laboratory hazards.
