Circle 301 on Reader Service Card the innovative protective equipment designed for coaters, blasters and painters. TheASH-301 has approval through MSHA/NIOSH as a type C or CE respirator to be used as a paint hood, as well as an abrasive blast hood. The hard shell meets

ANSI standards for face and eye protection, yet the complete unit weighs less than five pounds. The foam inner liner gently holds the head in order to hold the wide view- ing window in place. The foam also distributes quieter air throughout the inner chamber and fits over the ears for additional hearing protec- tion.

The 301-14 airline filter was de- signed to provide cleaner, safer air on a more stable base for use in blasting yards or in a shop environ- ment. The replaceable filter car- tridge traps and removes 98 percent of impurities down to 1/2 micron in size. Northstar also manufactures a disposable hood, full face constant flows respirator and approved breathing air hoses.

REED MINERALS

Reed Minerals, a Harsco Com- pany, manufactures a coal slag abra- sive under the trade name of Black

Beauty® at 15 different plants throughout the U.S.

Reed Minerals has been manu- facturing Black Beauty since the early 1940's and is one of the largest coal slag abrasive processors in the

U.S. Black Beauty is utilized by the marine industry for their abrasive needs.

The product name Black Beauty refers to a by-product of the combus- tion of coal which is processed into abrasive products. Typically, it is fused ferro-alumino-silicate of com- plex composition, formed when the molten slag is quenched in cold wa- ter. The quenching instantly solidi- fies the molten solution into an amor- phous or non-crystalline glass, and by thermal shock, fractures the slag into rough, angular particles. The overall appearance of the material is that of a coarse, black aggregate.

Black Beauty has a range of six to seven on the Moh's Scale of Mineral

Hardness, and is characterized by low friability and low-dusting, which is especially important on jobsites in congested areas or where emis- sion containment is specified. The abrasive is also classified as a "low free silica" abrasive and can be used where "low free silica" abrasives are specified. Black Beauty is also re- ported to be chemically inert and virtually non-leachable as demon- strated by independent laboratory testing.
