Maintain a safety distance of at least 15 feet from high voltage power lines for general activities, but the exact distance varies significantly by voltage and the situation

 Maintain a safety distance of at least 15 feet from high voltage power lines for general activities, but the exact distance varies significantly by voltage and the situation. For downed lines, stay at least 35 feet away and do not approach. When working near power lines, remember that electricity can arc to nearby objects like trees, and the ground can become energized. Always call your local power company for specific clearance requirements and safety guidelines, especially when working or driving near lines. 

General safety distances

For voltages up to 50 kV: Maintain a minimum clearance of 6 feet.

For voltages between 50 kV and 345 kV: A minimum clearance of 10 feet is recommended.

For all high voltage lines: A minimum of 15 feet is a general rule of thumb to prevent arcing and allow for safe access for repair crews. 

For downed power lines

Stay a minimum of 35 feet away from any downed power line.

Do not touch the line or anything in contact with it, including a tree or vehicle.

Call 911 and your local electric utility to report the downed line.

Warn others to stay away. 

Tree and vehicle safety

Trees: Never trim branches near power lines. The electricity can travel through the tree and through the ground, making the entire tree and the surrounding area dangerous. If a tree falls on a power line, it can energize the tree and ground.

Buses: Buses are large and can become a hazard if they come too close to power lines. The height of the bus can put it at risk of making contact with overhead lines, leading to a serious accident. If a bus contacts a power line, it can become energized and electric shock can travel through the bus and its occupants. The bus should be moved away from the power line as quickly and safely as possible. 

Additional tips

Listen for crackling or buzzing: If you hear a high-pitched buzzing or snapping sound, you may be too close to a high-voltage line, especially during humid conditions.

Do not use a tape measure: Never use a tape measure or any other measuring device to determine the distance to the power line, as it can become a conductor for electricity.

Call the utility company: When in doubt, call your local electric utility for the specific safety guidelines for your area.

  1. A 20-liter drinking water can should be cleaned thoroughly every 3 to 6 months, or whenever a water filter is swapped, and a daily rinse with soapy water is recommended if the water is left in the can for extended periods. Improperly cleaned cans can lead to bacterial growth and potential health issues, especially for those with compromised immune systems.
    Cleaning frequency
    Deep cleaning: Clean the can thoroughly every 3 to 6 months.
    Filter changes: Clean the can whenever you replace the water filter for it.
    Daily: It is recommended to give the can a quick rinse with soapy water and a brush at least once a day, especially if the water is not consumed quickly.
    Why cleaning is important
    Prevents bacterial growth: Bacteria from your mouth and the air can enter the can and multiply rapidly in moist environments.
    Reduces risk of illness: While many bacteria are not harmful, they can cause illness in people with weakened immune systems.
    Removes residue: Residue can build up and provide a breeding ground for bacteria and mold.
    How to clean a 20-liter water can
    Empty the can: Make sure all water is removed from the can.
    Use a cleaning solution: A mixture of one part white vinegar to three parts water or a few teaspoons of baking soda in warm water is effective for a deep clean.
    Scrub thoroughly: Use a long-handled brush to scrub all internal surfaces. For the best results, use a high-pressure jet if available.
    Rinse well: Rinse the can thoroughly with clean water to remove all cleaning residues.
    Dry completely: Let the can dry completely, preferably upside down with the lid off, to prevent moisture from encouraging germ growth.
    Replace the lid: Once the can is completely dry, put the lid back on to keep it clean for the next use.
