What is BS EN 16228-6 - jetting, grouting, and injection equipment safety about?
The construction, mining, and civil engineering sectors utilize drilling equipment and procedures to drill into both rock and soil. BS EN 16228-6 is a European Standard that discusses safety requirements for drilling and foundation equipment for the safe and proper operation, maintenance, and service of the drilling and foundation equipment.
BS EN 16228-6 is the sixth part of the ‘Drilling and foundation equipment – Safety’ multi-series; and deals with all significant hazards for jetting, grouting, and injection equipment; associated with the whole lifetime of the machine.
The requirements of this part are complementary to the common requirements formulated in EN 16228-1:2014.
Note 1: BS EN 16228-6 does not repeat the requirements from EN 16228-1:2014, but adds or replaces the requirements for application for jetting, grouting, and injection equipment.
Note 2: Rigs for drilling, vibrating, pile driving, to be used for preparing holes for these applications are covered by EN 16228-2:2014 and/or EN 16228-4:2014.
Who is BS EN 16228-6 - jetting, grouting, and injection equipment safety for?
BS EN 16228-6 on jetting, grouting, and injection equipment safety is useful for:
- The construction industry
- Civil engineering projects
- Relevant government authorities that commission engineering projects
- Contractors
- Drilling and foundation equipment manufacturers
- Entities involved in commissioning, maintenance, and operation of drilling and foundation equipment
- Regulatory bodies / Health and safety bodies
- Site managers
- Machine operators and trainers
- Supervisors
Why should you use BS EN 16228-6 - jetting, grouting, and injection equipment safety?
The activity of drilling has inherent potential safety hazards which need to be addressed. The BS EN 16228 series intends to mitigate these risks. Jet grouting creates in-situ columns of grouted soil using very high-pressure grout injection. The machinery concerned and the extent to which hazards are covered are indicated in the scope of BS EN 16228-6.
BS EN 16228-6 contains all hazards, (hazardous situations and events), identified by risk assessments as significant for jetting, grouting, and injection equipment and which require action to eliminate or reduce risk.
Jetting, grouting, and injection equipment are used in the preparation, transfer, and application of grouting materials used for either:
- The improvement of the ground condition
- The filling of voids e.g. around piles or ground anchors
Jetting, grouting, and injection equipment are constituted by all equipment 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 hook
When a jetting, grouting, or injection unit is intended to use products that generate toxic gases, the manufacturer provides a forced ventilation system and an atmosphere control device with an acoustic or flashlight warning signal.
BS EN 16228-6 provides specific requirements on information for use, such as instruction handbooks and marking. BS EN 16228-6 guides you on ways to improve soil carrying capacity while also lowering settlement, liquefaction risk, and permeability.
BS EN 16228-6 guidelines help you during maintenance, as well as transportation to and from the worksite.
By providing the safety requirements for drilling and foundation equipment, BS EN 16228-6 helps to establish operational stability and reliability, while successfully minimizing the incidence of occupational hazards arising from improper use or product failure. BS EN 16228-6 enables you to mitigate risks and safely accomplish a wide range of complicated jobs.
