1.  Educate yourself properly. Know and identify the possible scenarios for injury regarding your activity in order to prevent them. Learning basic first aid is also invaluable for outdoor recreation.
2. Always pack accordingly for your activity. A first aid kit with basic, versatile supplies is a must, and tools such as a hatchet or compass can be essential in the outdoors. Also make sure you have packed an ample supply of drinking water, especially during the summer.
3. If you are going hiking, camping or any other outdoor activity in a remote location, notify someone of where you are going, what you are planning to do and the time you expect to return. Leave a phone number to call if you do not return on time.
4. When engaging in water sports, always wear a floatation device and abstain from consuming alcohol.
5. Be aware of your surroundings and what you have on hand. Knowing where your nearest sources of water and shade are located can be crucial when dealing with heat stroke or other types of injury. And common items like a bandana or other items of clothing can be used as bandages or slings.
6. Know your and your companions’ medical histories to anticipate any complications that may arise and prepare accordingly. For example, if you have an allergy to stinging insects, it’s a good idea to carry an EpiPen.
7. Remember that you are “number one.” Never put yourself at risk to help or rescue someone in distress. Seek help and let trained first responders do their job.
