While exploring abandoned mines can be dangerous, the majority of deaths on mine property are actually unrelated to mine exploration. The leading causes of accidental deaths on abandoned mine properties are drownings in open quarries and ATV accidents. These types of accidents often occur when people engage in recreational activities on abandoned mine sites without taking proper precautions or following safety guidelines. It is important for individuals to recognize the risks associated with these activities and to take steps to ensure their safety. Property owners and managers also have a role to play in preventing accidents by implementing safety measures and providing adequate warning signs and barriers. The U.S. Department of Labor notes that since 1999, "more than 200 people have died in recreational accidents at the surface and underground active and abandoned operations across the country."<sup id="cite_ref-11" class="reference"><a href="#cite_note-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> Due to these circumstances, the <a href="/wiki/Mine_Safety_and_Health_Administration" title="Mine Safety and Health Administration">Mine Safety and Health Administration</a> launched the "Stay Out – Stay Alive" campaign, which is a national public awareness campaign aimed at warning and educating children and adults about the dangers of exploring and playing on active and abandoned mine sites. </p><p>In the U.S., the Abandoned Mine Land Initiative, launched by the Western Governor's Association and the <a href="/wiki/National_Mining_Association" title="National Mining Association">National Mining Association</a> is also an effort focusing on reporting the number of high-priority AML sites.<sup id="cite_ref-12" class="reference"><a href="#cite_note-12"><span class="cite-bracket">[</span>12<span class="cite-bracket">]</span></a></sup> The initiative identifies, measures, and reports on the progress of current reclamation cleanup programs on an annual basis.
