According to OSHA regulations, should an operator wear contact lenses when dealing with ammonia refrigerant?

Wearing contact lenses while handling ammonia refrigerant is not advisable according to OSHA regulations due to the potential hazards associated with ammonia exposure. Ammonia is a corrosive substance that can harm the eyes and respiratory system. If exposure occurs, contact lenses can trap the ammonia against the eye surface, leading to more severe injuries or complications.

In environments where ammonia is present, safety protocols typically emphasize the use of protective eyewear that provides a barrier against splashes or airborne materials. This ensures that the eyes are adequately protected from corrosive agents, which is essential for safe operations. Thus, the recommendation against wearing contact lenses helps to minimize health risks and protect the operator effectively.
