For educational purposes only
This guide is educational information about first aid and home safety — it is not medical advice, and it is not a substitute for professional medical care or hands-on, certified first-aid and CPR training. It does not diagnose, treat, or replace emergency care. Knowing first aid saves lives, but reading about it is not the same as being trained — consider a certified course (for example through the Red Cross or St John Ambulance). In any real emergency — including severe bleeding, a serious allergic reaction, a seizure, suspected poisoning, or heat stroke — call 911 (or your local emergency number) immediately and follow the dispatcher's instructions.
