This document specifies the specific safety requirements for jetting, grouting and injection equipment when used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer. Rigs for drilling, vibrating, pile driving, to be used for preparing holes for this applications are covered by prEN 16228-2 and/or prEN 16228-4. Jetting, grouting and injection equipment is used in the preparation, transfer and application of grouting materials used for either: - the improvement of ground condition; or - the filling of voids e. g. around piles or ground anchors. Jetting, grouting and injection equipment includes all machinery and installations, operated by hand or electrically, pneumatically, mechanically or hydraulically powered, necessary for the following: - mixing, storing, measuring and pumping of substances (cement suspension, mortar or chemical liquids/mixtures); - jetting, grouting and injection processes (of/into subsoil) with low, medium or high pressure or vacuum systems; - all types of pressure and wear resistant grout hoses, fittings, quick release coupling with thread or hose connection, ball valves and flexible pipes; - all control systems, electrical or mechanical pressure and flow recorders, for monitoring the grouting; - all jetting, grouting and injection accessories, such as: special tools, lances, rods, sockets, packers, retention clamps and swivel hooks. This document does not repeat the requirements from part 1, but adds or replaces the requirements for application for jetting, grouting and injection equipment. This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards, hazardous situations and events during commissioning, operation and maintenance of jetting, grouting and injection equipment.
