Wisconsin Pesticide Applicator Practice Test

What type of goggles should you wear when tank mixing highly toxic sprays?

1. Loose-fitting goggles

2. Tight fitting goggles with antifog lenses and indirect venting

3. Regular safety glasses

4. Standard construction goggles

The correct answer is: Tight fitting goggles with antifog lenses and indirect venting

Wearing tight-fitting goggles with antifog lenses and indirect venting is essential when tank mixing highly toxic sprays because these types of goggles provide an effective barrier against chemical splashes and vapors. The tight fit ensures that there are no gaps through which potentially harmful substances can enter, offering a higher level of protection for the eyes compared to other types of eye protection. Antifog lenses are particularly important in situations that may involve contact with liquids or heat, as they help maintain clear vision by preventing fog build-up on the lens, which can obstruct sight and increase the risk of accidental exposure. Indirect venting plays a critical role by allowing air to circulate and minimize fogging while reducing the likelihood of liquid entering the goggles. Other options like regular safety glasses do not provide the same level of protection against chemical exposure, as they may not seal around the eyes effectively. Loose-fitting goggles and standard construction goggles may also fail to adequately protect against splashes and the potential inhalation of toxic pesticides, making tight-fitting goggles the appropriate choice for safety when handling hazardous materials.
