Prioritize safety

Before helping, consider whether the environment is safe for you and the person who needs assistance.

Know important information

Emergency information can include allergies, medicines, known conditions and emergency contacts when available and appropriate.

Use appropriate training

First-aid procedures should follow recognized training and current guidance. Do not attempt unfamiliar procedures when professional help is available.

Preparing for common first-aid situations

Basic first aid focuses on immediate practical steps while appropriate medical help is obtained when necessary. A useful first-aid kit may contain items such as clean dressings, adhesive bandages, gauze, gloves, and other appropriate supplies. Check supplies periodically and replace items that are damaged or expired.

For a minor injury, the first step is to make sure the surrounding area is safe. Depending on the situation, basic care may involve protecting the injury, controlling minor bleeding, and keeping the affected area clean. More serious injuries require professional assessment rather than relying only on home treatment.

First-aid knowledge has limits. Severe bleeding, major burns, loss of consciousness, serious breathing difficulty, suspected stroke or heart attack, severe allergic reactions, poisoning, major trauma, or other emergencies require urgent medical assistance. Follow local emergency guidance and contact emergency services when appropriate.

Learning before an emergency

First aid is easier to apply when people learn the basics before an emergency happens. Consider taking a recognized first-aid or CPR course if one is available through a reputable training organization. Practical training can teach skills that are difficult to learn from written instructions alone.

Knowing the limits of first aid

First aid is intended to provide immediate basic assistance while a person receives appropriate care. It does not replace professional treatment. The correct response depends on the injury or illness, the person's condition, and the resources available at the time.

Before helping, check that the environment is safe for you and the injured person. If there is a serious emergency, contact the appropriate emergency service as soon as possible. Follow instructions from emergency responders and avoid attempting procedures that you have not been trained to perform.

For minor injuries, basic measures may include protecting the affected area, controlling minor bleeding, and keeping wounds appropriately clean and covered. Serious bleeding, severe burns, suspected fractures, major head injuries, difficulty breathing, unconsciousness, poisoning, or other severe conditions require prompt professional medical attention.

Preparing before an emergency

A first-aid kit should be checked regularly so that important supplies are available when needed. Learning first aid and CPR through recognized practical training can also be valuable because emergency situations can be difficult to manage from written instructions alone.

Keep emergency contact information accessible and make sure household members know where basic first-aid supplies are stored. Preparation can reduce confusion when a situation develops unexpectedly.
