1.4. OSHA Guidelines for High Voltage Lines

Try these first

1. 1.

   What is the minimum distance required from high voltage lines according to OSHA?

   Hint

   Think about safety distances discussed in class.

2. 2.

   What should be provided if the ground is weak?

   Hint

   Remember the support concepts for outriggers.

3. 3.

   What is the minimum distance a crane should maintain from high voltage lines?

   • 1 meter
   • 3 meters
   • 5 meters

   Hint

   Consider the overview of electrocution hazards we've discussed.

4. 4.

   True or False: Outriggers are optional when setting up cranes.

   • True
   • False

   Hint

   Recall the statistics about accidents related to improper setups.

5. 5.

   A crane needs to lift a load weighing 15000 kg to a height of 45 meters, while the load is located 25 meters from the crane. Using the crane range diagram, determine the appropriate boom length required.

   Hint

   Refer back to the range diagram for your height and distance.

6. 6.

   Discuss the implications of using a crane in windy conditions. How would you mitigate risks associated with high wind speeds?

   Hint

   Think about what the guidelines say about safety precautions.
