*Use as a part of an OSHA compliant silica dust suppression system.

OSHA's new Respirable Crystalline Silica (RCS) Standard has taken effect as of September 2017 and will be fully enforced in all industries beginning June 23, 2018.

Very small particles of respirable crystalline silica are created when drilling, crushing, cutting or grinding materials such as stone, brick, mortar and concrete. Occupational exposure to RCS is associated with pneumatic jackhammer and breaker operation in the construction industry. Without suppression methods, this exposure can cause serious health effects such as silicosis, lung cancer and COPD. OSHA requires a wet method suppression system, a solution that is compliant with industry practices and government research.

Parker's air-water jackhammer 7084 series hose helps companies comply with the new standard. The 7084 series Twinhammer™ hose is a chemically bonded air/water hose assembly that is easy to handle and serves as an integral component of a silica dust suppression system. It is specifically designed for use with industrial air compressors and jackhammers.
