Specific Responsibilities for Additive Manufacturing:

• Follow Manufacturer Instructions: You must ensure that all additive manufacturing equipment is installed, operated, and maintained in strict accordance with the manufacturer’s instructions.
• Dust and Metal Compliance: If your operation involves combustible dusts or metals, you must also comply with the specific requirements of CFC Chapter 22 (Combustible Dusts) and/or Chapter 59 (Flammable Solids), including conducting a Dust Hazard Analysis.
• Powder Combustibility: You are responsible for determining the combustibility and explosibility of any metal powders used in the process. This may require testing in accordance with ASTM E1226.
• Fire/Explosion Protection: Continuously maintain all required fire and explosion protection systems, such as specialized fire suppression, explosion venting, or inert gas systems, in full working order.
• Dust Control: Regularly inspect and maintain the dust collection system to ensure it is operating effectively and preventing the accumulation of combustible dusts on surfaces.
• Control Ignition Sources: Strictly control all potential ignition sources in the manufacturing area, including static electricity, open flames, and hot surfaces.
