HEALTH AND SAFETY
Take all necessary steps to ensure your safety and the safety of others:
-
Ensure adequate ventilation or mechanical dust extraction when cutting or drilling.
-
Ensure the timber and fibre cement sheets are well supported when cutting and nailing.
-
Wear appropriate safety equipment, clothing, footwear and eye protection.
-
Use all tools in accordance with relevant instruction manuals.
-
Ensure all tooling is sharp.
-
Plan and monitor a safe approach for working at height; select and use the right equipment. Do not step directly on the sheets between roof purlins. Always use stepping ladders or crawling boards supported by a minimum of three roof structural elements.

Storage
Store boards in a flat area undercover and off the ground. Place on a pallet
or supported by timbers running the length of the boards. Store rolls of wrap
in a dry location and undercover.
TOOLS AND EQUIPMENT REQUIRED
Install the system using standard carpentry tools and equipment.
