PROXIMITY TO OVERHEAD ELECTRICAL EQUIPMENT
| Normal Phase to Phase Voltage Rating | Minimum Distance |
| 750 – 150,000 Volts | 3 Metres |
| 150,001 – 250,000 Volts | 4.5 Metres |
| Over 250,000 Volts | 6 Metres |

LOADING AND UNLOADING
*Loading and unloading the cage should be done in a manner that will not upset the stability of the cage. E.g.: Do not unload one side of the cage all at once while leaving the other side full. This may cause the cage to tip, roll or fall.
*An example of how to unload a standard form cage of 24” panels would be to remove approximately 5 to 6 panels from one side, then manually lay the other forms one at a time to the opposite side of the cage in a controlled manner. Then remove forms from the opposite side.
*It is recommended that people using this product check the cage’s stability as they are loading and unloading each form to make sure the cage is still stable.
*When loading and unloading the cage it is important to pay attention that the forms do not shift.
*Failure to keep the cage balanced may cause the cage to tip, roll or fall, possibly causing injury or death.
