Should an operator wear contact lenses when dealing with refrigerant ammonia?

Wearing contact lenses while handling refrigerant ammonia is not advisable due to the potential hazards associated with this toxic substance. Ammonia can cause severe irritation and damage to the eyes. If ammonia were to leak or splash, the contact lenses could trap the chemical against the eye, exacerbating injury and making it more difficult to flush the chemical away effectively.

For operators working with ammonia, protective eyewear such as goggles or face shields that provide a secure seal around the eyes are recommended. These forms of eye protection can help prevent exposure to harmful substances, ensuring a higher level of safety in industrial environments. In addition, goggles can be easily removed in case of exposure to a hazardous situation, allowing for immediate decontamination. This approach emphasizes the importance of using proper personal protective equipment when working with hazardous materials.
