Exposure SPONSORED BY to Dust EXTRACTION PLAN! The experts at EJOT UK discuss a new solution to protect against airborne concrete dust and debris contamination. The airborne distribution of dust and debris created from a variety of construction site activities has become a priority focus for the UK Government’s Health and Safety Executive (HSE). For example, the HSE’s CIS69 document provides guidance on choosing, using and maintaining on-tool extraction to control construction site dust. This dust may contain some very fine dust called respirable crystalline silica (RCS) and exposure to RCS dust can be the cause of varying levels of health 1 problems – many serious. This and other documents also highlight the legal responsibilities for employers to either prevent or adequately control ‘worker exposure’ to high levels of dust created by a variety of tasks that include cut-off saws, grinders, breakers and sanders. Logical then, that SDS drilling into concrete, brick and block substrates presents the same potential hazards. What is SDS drilling? Our German colleagues will Modularity makes sense Optional Vortex Vacuum say that SDS stands for “Steck-Dreh-Sitz” or “Plug in-Twist-Take-up device”. Internationally, the abbreviation means “Special Direct System”, whilst in the UK “Slotted Drive System” is also commonly used. Whichever version you favour, the SDS design utilises these slots to allow the drill’s hammer action to thrust the drill bit forward whilst being retained by ball bearings seated within the slotted indentations. The bottom line is that a standard SDS Plus drill is an 2 4 6 DUST-FREE DRILLING into dense concrete brick and block Standard SDS drilling into concrete, brick and block substrates Standard SDS drilling sends dust and debris into the air while correct installation requires necessary time to clean the drill hole. EJOT vortex-SDS drilling virtually eliminates dust at source, reducing hazards and saving site time. !

EJOT vortex-SDS: solutions-driven R&D Significantly, global fastener manufacturer EJOT acquired the Liebig ‘metal anchoring into concrete’ brand in 2017. This has naturally contributed to EJOT’s R & D team in the UK having a heightened awareness e, POWERFUL DUST REMOVAL AT T SOURCEE Instant t dust extraction at source EJOT vortex-SDS drilling components have specially ly designed carbide tips, specifically for SDS S extraction systems. Dust is drawn inside the drill bit and directl ly to the H-class vacuum. The drill trigger automatically powers the vacuum and extraction continues for a full 10 seconds once re eleased. Cleaner er air , cleaner installation The four-cutter design creat tes a cleaner, more precise drill hole, drastically reducing time spent removing dust for metal anchor installation. ation. Virtually no dust means less friction leading to faster drilling. Job done! Best practice means safer practice. Virtua ally dust-free drilling and a more efficient ent installation process. www.ejot.co.uk EJOT has produced this handy infographic that talks through the process of its vortex-SDS tool. of the HSE’s focus on airborne concrete dust contamination. Working alongside industry partners, the company has developed ‘EJOT vortex-SDS’; a modular drilling system engineered from high quality materials, and providing instant dust-removal drilling, at source. The modular nature of EJOT vortex-SDS provides drilling options from 8 to 20mm diameter and appropriate depths up to 440mm, with obvious replacement and inventory advantages. Dust extraction at source The vented four-cutter design of each carbide drill tip initiates the powerful ‘vortex’ dust extraction force that is created within each operating component, drawing dust and debris directly through the system and into the industrial vacuum cleaner. An integral 16amp socket connector means that the vortex action is instant and occurs as soon as the drill is activated and continues for ten seconds after drilling has finished. The removal of dust lessens friction between the substrate and drill bit, thereby speeding The vortex-SDS kit comprises: • 4 x standard carbide tipped drill bits. • 8mm, 10mm, 12mm and 14mm diameters. • 70mm, 95mm, 120mm and 145mm lengths. • 1 x special drill-to-bit connector. • 1 x modular extension bar, 220mm length. • 3 x modular carbide tipped drill bits, 40mm length. • Choice of 16mm, 18mm and 20mm modular diameters. • Optional extra extension bar offers 20mm diameter holes at 450mm depth. • Components available individually on a replacement basis. installation and creating a cleaner, more accurate drill hole. For example, that can drastically reduce time accrued removing dust from the drill hole when installing mechanical anchors, virtually eliminating the need to blow the hole clean of dust. EJOT vortex V Industrial Vacuum The EJOT Vortex-SDS drilling system can be attached to any H-class industrial vacuum cleaner. As part of the system offering, EJOT partnered with international manufacturer Addex to provide a customised version of the MV-DV20 VAC. The vacuum can be used on a variety of surfaces and can withstand the toughest of treatment. Contact EJOT 01977 687040 www.ejot.co.uk @EJOTUK_Building 86 TC SEPTEMBER <strong>2019</strong>
