Assemblies Available Through the Parker Stores

thread id workshopNorthborough, MA (03-20-2018) -
The Hope Group announced today that it now has Parker's Twinhammer™ bonded air and water jackhammer hose assemblies available to its customers at a special introductory price. The 7084 series hose provides a wet method suppression system that complies with the recently created OSHA respirable crystalline silica (RCS) standard.

It is the first factory-assembled dual hose system that delivers both air and water in a single, unitized configuration for silica dust suppression in pneumatic jackhammer operations.

Product specifications and part numbers are printed on page 2 in the downloadable Twinhammer Hose PDF.

New OSHA Standard for Construction Industry

OSHA Violation PenaltiesThe U.S. Occupational Health and Safety Administration (OSHA) has created a new standard to address the problem of crystalline silica dust control associated with pneumatic jackhammer and breaker operation in the construction industry. The mandated compliance date of the new silica rule is September 23, 2017. As of 2018, the penalty per violation is $12,675. (Going forward, the agency will continue to adjust its penalties for inflation each year based on the Consumer Price Index.)

A wet method suppression system is a compliant solution suggested by industry practices and government research. However, some hose-oriented deployment methods may be less efficient and less effective than others:

  1. Manual Water Spraying Using a Helper
    A two-person job where a helper holds a water hose with a nozzle and sprays water at the locus of the jackhammer tip and work object
    • Efficiency is diminished by requiring two workers
    • Effectiveness is reduced by inconsistent water angle, distance, flow and spray pattern

  2. Independent and Unconnected Air and Water Hose Lines
    Hoses typically use bands or clamps to attach fittings

    • Effectiveness is hampered by requiring the operator to take time to regularly inspect the security of the fittings
    • Operator must maneuver independent hoses around debris, equipment and other obstacles to avoid hose damage and kinking

  3. Inefficient Hose Deployment Methods

    Taping hoses together

    Zip tie or strapping hoses together


  4. Independent and Mechanically Connected
    Air and Water Hose Lines

    Hoses typically use bands or clamps to attach fittings

    Apply zip ties, straps, tape or other connectors at multiple intervals along the lengths of both hoses to mechanically connect them

    • Effectiveness is hampered by requiring the jackhammer operator to devote attention, effort and time to:
      − Select, procure and apply zip ties, straps or tape to hoses,
      − Regularly inspect the security of the fittings and attachment components, and
      − Maneuver hoses whose zip ties, straps, tape and gaps between the hoses may become snagged by debris, equipment and other obstacles at the jobsite, becoming potential safety hazards
