PMT 103A Industrial Hygiene Practice Test

The essential idea is that portable eyewash stations must deliver enough water for a long enough time to properly flush eyes after exposure. The standard specifies a minimum flow of 0.4 gallons per minute for at least 15 minutes. This combination ensures a continuous, adequate rinse to remove contaminants from both eyes. The statement that matches 0.4 gpm for 15 minutes meets these minimum requirements exactly. A shorter duration (5 minutes) wouldn’t provide enough flushing time, while a higher flow (like 1 gpm) may still meet the standard but doesn’t reflect the required minimum pairing the question is asking for.
