Twinhammer Hose Created With Efficiency And Safety In Mind

New OSHA Standard for Construction Industry

The 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 2020, the penalty per violation is $13,494. (Going forward, the agency will continue to adjust its penalties for inflation each year based on the Consumer Price Index.). The Twinhammer Hose from Parker is a safe and efficient way to comply with the new OSHA standard. Learn about the pros and cons of traditional industry practices and the benefits of the Twinhammer Hose.

Traditional Industry Practices

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. 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 job site, becoming potential safety hazards.

New Efficient and Safe Solution

Parker’s Twinhammer™ bonded air and water 7084 series jackhammer hose provides a wet method suppression system that complies with the recently created OSHA respirable crystalline silica (RCS) standard.Twinhammer Hose

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.

Jackhammer Hose Spray Kit

Twinhammer Retrofit Kit
Parker’s jackhammer hose spray kit adapts jackhammers for water spray. Sold separately from Twinhammer Hose Assembly.

The jackhammer hose spray kit allows for the transfer of water from the supply hose to the jackhammer bit. The kit is easy and convenient to install and provides efficient and consistent water angle, distance, flow and spray pattern for effective silica dust control.

The kit is used with the Twinhammer hose as part of an OSHA-compliant wet method hose system for silica dust suppression. The kit includes the hardware and attachment components to apply to many models and generations of jackhammers.
