## Narrative

ASP Field Service Technician splashed with 19% Aqua Ammonia. There was an airlock in line at filter housing restricting flow to pump. Pressure pushed priming plug out and splashed Mono Goggles which pushed up on EE's face. Initial injury was trouble breathing and eye irritation from the Ammonia vapors and some burning on top lip. This all subsided with the introduction of water.
