Reading: Cutting and Shaping Metals Safely

Cutting and shaping require safety precautions to avoid injuries in metalwork. Cutting tools include hacksaws for straight cuts on thicker metal and shears for thin sheets. Shaping tools include files for smoothing edges and hammers with anvils for bending and forming. Wear protective gear like gloves and goggles to shield against debris and sharp edges. Secure clamping of workpieces prevents slipping, and deburring removes sharp edges promptly. Key techniques include steady pressure and proper tool handling to minimize risks.

Indigenous practices in the Kimberley and Pilbara used natural tools for cutting and shaping, emphasizing harmony with nature and safety through community knowledge. For example, stones or bones were used to shape metals, avoiding harm to the environment. These methods promote sustainable use and cultural respect, integrating with modern safety standards. Students learn to blend traditions for inclusive design. Safe cutting and shaping ensure precision and prevent accidents, aligning with indigenous values of care and respect. This lesson builds practical skills while honoring cultural heritage. (Word count: 167)
