+ | ===== Identify & mitigate common hazards ===== | ||
+ | |||
+ | * Metalworking when done properly is much quieter than woodworking. | ||
+ | * Knows the common causes of noise and which hazards they indicate (vibration, deflection, dull tooling). | ||
+ | * Heavy things – tooling, work holding equipment & workpieces. | ||
+ | * Sharp things - cutting tools, chips, burrs on work piece. | ||
+ | * Spinning things – spindle, axis wheels. | ||
+ | * Hot things - chips, work piece, tools. | ||
+ | * Toxic Fumes - avoid prohibited metals. | ||
+ | * Hot flying debris - use appropriate tools, work holding, and clear work area. | ||
+ | * Fire/Gas Leak - stay vigilant (listen/ | ||
+ | |||
+ | ===== Allowable Materials ===== | ||
+ | |||
+ | * Can name one common material that is safe for use on the mill. | ||
