What gas does the green label on a respirator indicate protection against?

The green label on a respirator indicates that the respirator is designed to provide protection against ammonia. Ammonia is a common irritant and can be found in various agricultural settings, especially in relation to certain fertilizers and pesticides. The labeling system for respirators is important as it helps users identify the specific gases or chemicals against which the respirator is effective. This is crucial for ensuring safety and compliance with health regulations in environments where exposure to harmful substances may occur.

In the context of pesticide application, knowing the specific protection level offered by a respirator can help applicators make informed decisions about their personal protective equipment, thereby minimizing risks associated with inhalation of toxic substances.
