Abstract: Apparatus is disclosed for quickly delivering a flow or spray of an eyewashing liquid such as water to the eyes of the wearer of a helmet or hard hat. A reservoir of appropriate liquid is formed within the helmet or hard hat. Air pressure is applied to the body of liquid by means of an associated pneumatic priming pump. Conduits communicate between the reservoir and duct members which are positioned to direct the flow of liquid into the eyes of the user. The duct members are opened by the pulling of a string which releases plugs located therein.
