NPK launches dust suppression kits for PH hammers

In 2016 OHSA introduced a new regulation regarding occupational exposure to respirable crystalline silica in construction work (1926.1153). Part xvii specifies acceptable work practices pertaining to heavy equipment used to break silica-containing materials, i.e. concrete demolition. The first option is to work from within an enclosed cab. If this is not possible, the standard is to apply water and/or dust suppressants as necessary to minimize dust emissions. NPK’s solution is the all-new add-on — water-ready dust suppression kit.

NPK dust suppression kits are available for PH1, PH2, PH3 and PH4 hydraulic hammers in redesigned enclosed brackets. Starting in Q4 2019, all PH1 – PH4 enclosed hammer brackets will be manufactured with the new design elements that allow these hammers to dispense water with the addition of a hose and a couple of fittings. Just connect to an existing water supply.

An integrated water spray nozzle eliminates the need for manual spraying. Located in the bracket of the hammer keeping it safe from flying debris, the nozzle is aimed at the point where the hammer’s tool makes contact with the breaking area. This, combined with a wide spray angle, provides maximum dust suppression coverage.

This kit helps to control airborne dust/silica in two ways. Upon breaking, particles are sprayed with mist. The mist combines with particles, which increases weight and leads them to drop back to the ground. Secondly, the mist douses the breaking area prior to impact, reducing the amount of dust generated. However, water flow rates are low enough that the likelihood of flooding the work area is minimal.

This is designed for use with mini excavators, backhoes or skid steers within the recommended carrier weight ranges. Visit the Attachment Wizard on the website to see which NPK attachments are suitable for your carrier.
