Section 5(a)(1) of the Occupational Safety and Health Act of 1970: The employer did not furnish employment and a place of employment which were free from recognized hazards that were causing or likely to cause death or serious physical harm to employees in that employees were exposed to: (a) In the machine shop for the employee operating the Hwacheon HI-ELO21HS CNC lathe machine #41, serial #M058346D6K, where the lathe was not equipped with a functioning door interlock device exposing the employee to the potential hazard of being struck by parts expelled from the turning lathe or being caught in the moving machinery inside the turning lathe by opening the lathe door during the machine operating cycle. (b) In the machine shop for the employee operating the Hwacheon HI-ECO21HS CNC lathe machine #40, serial #M058346D6K B, where the lathe was not equipped with a functioning door interlock device exposing the employee to the potential hazard of being struck by parts expelled from the turning lathe or being caught in the moving machinery inside the turning lathe by opening the lathe door during the machine operating cycle. (c) In the machine shop for the employee operating the Mori Seki SL-20 CNC lathe machine #45 where the lathe was not equipped with a functioning door interlock device exposing the employee to the potential hazard of being struck by parts expelled from the turning lathe or being caught in the moving machinery inside the turning lathe by opening the lathe door during the machine operating cycle. (d) In the machine shop for the employee operating the Mori Seki SL-20 CNC lathe machine #44 where the lathe was not equipped with a functioning door interlock device exposing the employee to the potential hazard of being struck by parts expelled from the turning lathe or being caught in the moving machinery inside the turning lathe by opening the lathe door during the machine operating cycle. (e) In the machine shop for the employee operating the Hwacheon HI-ECO31A A CNC lathe machine #39, serial #M0573460B2L-B, where the lathe was not equipped with a functioning door interlock device exposing the employee to the potential hazard of being struck by parts expelled from the turning lathe or being caught in the moving machinery inside the turning lathe by opening the lathe door during the machine operating cycle. (f) In the machine shop for the employee operating the Mori Seki SL-25Y CNC lathe machine #38, serial #159, where the lathe was not equipped with a functioning door interlock device exposing the employee to the potential hazard of being struck by parts expelled from the turning lathe or being caught in the moving machinery inside the turning lathe by opening the lathe door during the machine operating cycle. (g) In the machine shop for the employee operating the Mori Seki SL-25Y CNC lathe machine #43, serial #1294, where the lathe was not equipped with a functioning door interlock device exposing the employee to the potential hazard of being struck by parts expelled from the turning lathe or being caught in the moving machinery inside the turning lathe by opening the lathe door during the machine operating cycle.(h) In the machine shop for the employee operating the Fadal machine center machine #53, serial #012001062518, where the machine center was not equipped with a functioning door interlock device exposing the employee to the potential hazard of being struck by parts expelled from the machine center or being caught in the moving machinery inside the machine center by opening the machine center door during the machine operating cycle. (i) In the machine shop for the employee operating the Doosan Diamond Series DMV 4020 machine center, serial #AV5E 2443, where the machine center was not equipped with a functioning door interlock device exposing the employee to the potential hazard of being struck by parts expelled from the machine center or being caught in the moving machinery inside the machine center by opening the machine center door during the machine operating cycle. Among other methods, one feasible and acceptable abatement method to correct this hazard is to install a door interlock device on the CNC lathes and machine centers as required by ANSI B11.2-2002 Safety Requirements for Turning Centers Automatic Numerically Controlled Turning Machines, paragraphs 6.21 Safeguarding and 6.21.1.2 Automatic Mode which states: 1. Paragraph 6.21: Machines shall be safeguarded wherever practical by fixed or interlocked moveable guards: 2. Paragraph 6.21.1.2: Machine operation shall only be possible when the guards are closed and the safeguarding (protective) devices are active. If it is possible, in this mode, to open an interlocked moveable guard, the hazardous movement shall cease and be inhibited. Abatement Note: Abatement certification is required for this item (see enclosed "Sample Abatement Certification Letter").tion
