One person should be sufficient to lift the fire. If for any reason this weight is
considered too heavy then obtain assistance.

!

When lifting always keep your back straight. Bend your legs and not your back.

!

Avoid twisting at the waist. It is better to reposition your feet.

Avoid upper body/top heavy bending. Do not lean forward or sideways whilst
handling the fire.

!

Always grip with the palm of the hand. Do not use the tips of fingers for support.

!

Always keep the fire as close to the body as possible. This will minimise the
cantilever action.

!

Use gloves to provide additional grip.

!

Always use assistance if required.
