In the event of an emergency, dial 911.
In the desert you should play it safe by being prepared and taking a few simple safety precautions. Always travel with a companion, especially if you are not familiar with the area. Let someone know about your trip, destination, and estimated time and date of return. Carry a cell phone as a precaution, but know that reception in the desert can be spotty at best. Before setting out, make sure that your vehicle is in good condition. Carry a jack, tools, and tow rope or chain. Fill up your tank whenever you see a gas pump -- it can be miles between service stations. Stay on main roads: if you drive even a few feet off the pavement, you could get stuck in sand. Plus, venturing off-road is illegal in many areas. When driving, watch out for wild burros, horses, and range cattle. They roam free throughout much of the desert and have the right-of-way.
Drink at least one gallon of water per day, preferably more (three gallons if you plan on hiking or engaging in other strenuous activity), even if you don't feel thirsty. Dress in layered clothing and wear comfortable, sturdy shoes and a hat. Keep snacks, sunscreen, and a first-aid kit on hand. If you suddenly have a headache or feel dizzy or nauseated, you could be suffering from dehydration. Get out of the sun immediately and drink plenty of water. Dampen your clothing to lower your body temperature.
Avoid canyons during rainstorms. Floodwaters can quickly fill up dry riverbeds and cover or wash away roads. Never place your hands or feet where you can't see them. Rattlesnakes, scorpions, and black widow spiders may be hiding there.
