Safe Handling of Single Column Interlock Guards

To install the test stand’s guarding it is required to lift and move the interlocked guard,

improper lifting technique or handling of the guard could lead to injury or damage to the

equipment.

Before moving the guard, an assessment should be carried out by a qualified individual to

determine how to move the guarding safely.

Due to the weight and size of the guarding it is recommended that at least two
people are needed to lift a single column guard during the installation phase.
Refer to Section 9 for the precise weight of the guard.
