Final answer:
Before digging, you must call a service like "Call 811" to have utility companies mark underground lines, generally giving a notice of at least 48-72 hours. In unique situations, such as a meteorite landing at your home, contact local authorities, experts, and insurance providers.
Step-by-step explanation:
Before digging anywhere, it's essential to call the appropriate utility services to avoid damaging any underground infrastructure. This is often handled through a national service like "Call 811" in the United States, which is a free service that will notify the relevant utility companies of your intent to dig. The timeline for providing notice can vary, but typically, you must give at least a few days notice—commonly at least 48 to 72 hours before the planned digging. Utility companies will then send representatives to mark the location of underground lines so you can dig safely.
If you are dealing with a specific scenario, such as finding a meteorite at your home, the first call would be to local law enforcement to report the incident. Following local authorities, contacting a local museum or university with an astronomy department for professional advice on handling the meteorite sample would be needed. Additionally, it would be wise to reach out to your insurance provider to discuss whether any potential damage is covered under your homeowner's insurance policy.
