Find out who is hosting and where the party is before agreeing to attend
Share the address and your expected return time with someone you trust
Go with friends and agree to check in before anyone leaves or changes location
Identify the main exits soon after arriving
Make sure your phone is charged and you have a backup battery
Carry enough money to arrange independent transportation
Do not rely on someone you have just met for a ride home
Avoid communal punch bowls, open containers, and drinks with an unknown source; open sealed drinks yourself or watch your drink being poured; keep your drink with you and discard it if you lose sight of it
Avoid isolated rooms particularly when alone
Leave if the gathering becomes overcrowded, aggressive, difficult to exit, or otherwise uncomfortable
