• Employers are responsible for identifying all job site hazards, educating and training all persons who will operate and maintain these products, and ensuring that all blast operators and their assistants understand the warnings and information contained in these instructions relating to safe and proper operation and maintenance of this equipment. • Serious injury or death can result from failure to comply with all Occupational Safety and Health Administration (OSHA)regulations and all manufacturer’s instructions. • This equipment is not intended for use in any area considered hazardous per...

OPERATOR SAFETY EQUIPMENT • OSHA regulation 1910.134 requires appropriate respiratory protection for blast operators and workers in the vicinity of blasting. These workers must wear properly-fitted, properly-maintained, NIOSH-approved, respiratory protection that is suitable for the job site hazards. Blast respirators are to be worn only in atmospheres not immediately dangerous to life or health from which wearers can escape without use of the respirator. • The employer must develop and implement a written respiratory protection program with required worksite- specific procedures and elements...

BLAST MACHINES AND REMOTE CONTROLS OSHA regulation 1910.169 describes the necessity of pressure relief valves on compressed air equipment. Do not operate blast machines with air compressors that are not equipped with properly functioning pressure relief valves. OSHA regulation 1910.244(b) requires the use of remote controls on blast machines. Serious injury or death can result from many sources, among them:  Involuntary activation of the remote controls. Never modify or substitute remote control parts; parts are not compatible among different manufacturers. Welding hose is not suitable for remote...

CLASSIC BLAST MACHINE with MANUAL CONTROLS 1.4 Abrasive Abrasives and dust from blasting may contain toxic materials (e.g., lead paint, silica) that are hazardous to workers. Obtain a safety data sheet (SDS) for the blast abrasive and identify all substances removed by the blasting process. • Silica sand (crystalline) can cause silicosis, lung cancer, and breathing problems in exposed workers. • Slags can contain trace amounts of toxic metals such as arsenic, beryllium, and cadmium and have the potential to cause lung disease. NO DUST IS SAFE TO BREATH. DUST PRODUCED FROM ANY ABRASIVE OR FROM...

CLASSIC BLAST MACHINE with MANUAL CONTROLS INITIAL SET-UP WARNING Clemco supplies an exhaust muffler with all blast machines of 2 cu. ft. capacity and larger. The muffler reduces exhaust noise and prevents abrasive from exhausting upward or sideways into the air. When the blast machine is depressurized, the muffler body pops up to diffuse the air and abrasive. When the machine is fully depressurized, the muffler body drops, permitting trapped abrasive to empty. For the muffler to work properly, it must be installed with the body facing up, as shown in Figure 1. Close Nipple If an application...

CLASSIC BLAST MACHINE with MANUAL CONTROLS AIR LINE RECOMMENDATIONS BASED ON NOZZLE SIZE Orifice Size Recommended Air Supply Line Refer to the compressed air and abrasive consumption table in Figure 6 for approximate air consumption. Hose disconnection while under pressure can cause serious injury or death. Use safety lock pins or safety wire to lock twist-on (claw-type) couplings together and prevent accidental separation while under pressure, and safety cables to prevent hose from whipping should separation occur. 2.4.2 Attach an air line from the compressor to the hose fitting installed on...
