A basic first aid kit helps you respond quickly to small injuries and emergencies at school, home, sports practice, or during outdoor activities. Having the right supplies in one easy-to-find place can reduce panic and prevent minor problems from getting worse. It is especially useful during weather events, field trips, earthquakes, power outages, and other situations where help may take time to arrive.
A good kit does not replace professional medical care, but it supports safe action while waiting for help.
Key Facts
- Check your first aid kit at least every 6 months and replace expired or used supplies.
- Emergency number rule: call 911 or local emergency services for serious bleeding, trouble breathing, chest pain, severe allergic reaction, or loss of consciousness.
- For minor bleeding, apply firm direct pressure with clean gauze for 5 to 10 minutes.
- For minor burns, cool the burn under clean running water for about 20 minutes, then cover it with a sterile dressing.
- Hydration estimate: daily water need during normal activity is about 30 mL per kg of body mass, but heat and exercise can increase this need.
- A useful kit includes bandages, sterile gauze, gloves, antiseptic wipes, medical tape, scissors, tweezers, instant cold pack, and emergency contact information.
Vocabulary
- First aid
- First aid is the immediate care given to an injured or ill person before professional medical help is available.
- Sterile
- Sterile means free from living germs that could cause infection.
- Antiseptic
- An antiseptic is a substance used on skin to reduce germs and lower the risk of infection.
- Emergency contact
- An emergency contact is a trusted person who should be called if someone is injured, sick, or unsafe.
- PPE
- PPE, or personal protective equipment, is gear such as gloves or masks that helps protect the helper and the injured person.
Common Mistakes to Avoid
- Using a first aid kit without checking expiration dates. Expired ointments, medicines, and damaged sterile packages may not work well or may no longer be safe.
- Touching blood or open wounds without gloves. This is wrong because it can spread germs between the helper and the injured person.
- Putting ice directly on skin for a long time. This can damage skin, so an instant cold pack should be wrapped in cloth and used for short intervals.
- Trying to handle a serious emergency alone. Serious symptoms need adult help and emergency services, even if the first aid kit is well stocked.
Practice Questions
- 1 A class first aid kit has 24 adhesive bandages. After a field day, 9 bandages are used. How many bandages remain, and how many should be added to restore the kit to 24?
- 2 A student has a mass of 50 kg. Using the estimate 30 mL of water per kg of body mass per day, how many milliliters of water does the student need in one day during normal activity?
- 3 During a school earthquake drill, a student finds a scraped knee with light bleeding and a student who is unconscious. Explain which situation should be handled first and why.
