Manual Handling

CSR Hebel recommends using a trolley or other mechanical apparatus to move the panels around the work site. Manual handling, where people physically move a panel, should be kept to a minimum, with the weight being supported by an individual kept as small as possible. Any concerns regarding the weight to be handled should be discussed with the panel installing contractor.

To minimise the possibility of manual handling injuries, CSR Hebel suggests the following:

■ Use mechanical aids, such as trolleys, fork lifts, cranes and levers, or team lifting to move panels.
■ Keep the work place clean to reduce the risk of slips, trips and falls which can cause injury.
■ Plan these quence of installation to minimise panel movements and avoid awkward lifts.
■ Keep the panels dry.
■ Train employees in good lifting techniques to minimise the risk of injury.

Hebel products are cement-based, which may irritate the skin, resulting in itching and occasionally a red rash. The wearing of gloves and suitable clothing to reduce abrasion and irritation of the skin is recommended when handling Hebel products.
