For nearly 60 years, Clemco’s Blast Off and then Blast Off 2 have been the gold-standard, pocketbook, reference manuals for the abrasive blasting industry. That’s why more than 1 million copies have circulated around the globe in numerous languages. Clemco distributors across the country for decades have used the booklets as training tools for their staffs. Industry educational organizations such as the Finishing Trades Institute and Contractor Campus have used the booklets in their classrooms. However, you’re even more likely to find the booklets in the pockets of operators in the field.

The manual for abrasive blasting

Blast Off was first published in 1963. As the abrasive blasting industry evolved, so did Blast Off. It went through several revisions, and the current edition is now titled Blast Off 2. It covers everything from how to position a blast machine, how to choose the best nozzle for a job, how to use safety equipment and to identify potential safety hazards, an overview of the elements of a complete blasting system, and every other imaginable topic in between.

In 1997, Clemco published the first edition of Abrasive Blasting Safety Practices. Subsequent editions of this booklet have become as popular as Blast Off 2. Both Blast Off 2 and Abrasive Blasting Safety Practices also are published in Spanish.

Clemco offers free copies of its manuals for workers in the industry. Request your copy of Clemco’s safety and training books here.

16 mm films—In color!

Shortly after Clemco published the first edition of Blast Off, it produced two films that illustrated the booklet’s content: Blast Off  the movie and the ABC’s of Surface Preparation. Clemco literature at the time proudly advertised free showings of these two 16 mm color films.

Through the magic of modern technology, Clemco has converted these 16 mm films into digital format. Before viewing these films, remember that Clemco was originally a division of Clementina, a contractor equipment-rental business headquartered in San Francisco, which is why San Francisco backdrops prominently appear in these films. So sit back, relax, and enjoy a bit of blasting industry nostalgia (in color!).

What do shotguns and sandblasting have in common?

In the 1950s, Clemco (sometimes under the Clementina name) began publishing information about the abrasive blasting industry. Two notable booklets were Sandblasting with Clemco and Sandblasting from a Practical Standpoint, which on Page 1 describes the “Similarity of a Shotgun with Sandblasting.” Today, the abrasive blasting industry recognizes that sand should NEVER be used in abrasive blasting operations because of the respiratory hazards associated with the use of abrasive containing free silica. Breathing abrasive containing crystaline (free) silica can lead to serious or fatal lung disease. However, this was standard practice at the time.

Within the booklet, several colorful comparisons were made between hunting with a shotgun and blasting with a Clemco machine, such as:
