What safety precautions should be taken when using a mitre saw?

• Use the mitre saw without ear protection
• Wear a face shield instead of safety goggles
• Touch the blade while it is still spinning
• Wear safety goggles, ear protection, and a dust mask. Keep hands away from the blade, use clamps to secure the workpiece, and wait for the blade to stop completely before lifting it.

Roof trusses are structural components typically made of wood or metal, consisting of interconnected triangles designed to ___________ the load of the roof.

Joists and bearers are essential components in construction for supporting the ____________ of a building.​ (a)  

• Floor
• Wall
• Roof
• Windows

What is the SOP's (Standard Operating Procedures) when using a mitre saw?​

• Ensure the mitre saw is placed on a stable and level surface. Adjust the table and fence as needed for the specific cut.

• Switch on the mitre saw and allow it to reach full speed before bringing the blade down to the workpiece.

• After completing the cut, release the trigger and allow the blade to come to a complete stop before lifting it.

• Check the saw blade for any damage or dullness before operation. Replace or sharpen the blade if necessary.

The National Construction Code (NCC) typically outlines requirements for bracing roof trusses to ensure structural stability and compliance with building codes and standards.

• Follow the requirements outlined in the National Construction Code (NCC) to ensure structural stability and compliance with building codes and standards.

• Ignore the requirements in the National Construction Code (NCC)

• Use rubber bands instead of proper bracing for roof trusses
• Brace the roof trusses with duct tape

Answer explanation

In building and construction, roof trusses are important Structural components that support the weight of the roof and distribute it evenly to the walls of a building. The National Construction Code (NCC) sets out guidelines for how roof trusses should be braced to ensure they remain stable and secure. Bracing helps prevent the trusses from buckling or collapsing under various loads such as wind or snow. The NCC specifies minimum requirements for bracing, which typically include the type of bracing materials to be used, their placement, and the method of installation. By following these requirements, builders can ensure that roof trusses are properly supported and meet the necessary safety standards.

Roof trusses are composed of interconnected ___________, which provide structural support and stability to the roof of a building.
