If liquid ammonia comes into contact with the eyes, what is the usual result?

Liquid ammonia is a highly corrosive substance that can cause severe damage upon contact with human tissues, including the delicate tissues of the eyes. When ammonia comes into contact with the eyes, it can lead to serious chemical burns that may result in extensive damage to the cornea and other structures within the eye. This damage can be profound and, in many cases, may lead to non-reversible blindness.

The severity of the injury is heightened by the fact that ammonia can penetrate tissues quickly and lead to inflammatory responses that further impair vision. While some injuries might be treatable, the potential for permanent damage is significant, making it critical for anyone exposed to liquid ammonia in an occupational setting to seek immediate medical attention.

The other options do not accurately reflect the serious nature of ammonia exposure to the eyes. Temporary irritation or redness and swelling may occur with many irritants but are less applicable to the severe effects of liquid ammonia. While complete restoration of vision might occur with certain ocular injuries, the risk of non-reversible blindness associated with ammonia exposure is a crucial factor to consider.
