If you find yourself in a situation where a stranger needs first aid, you should ask before attempting to treat them. If a person is unconscious, they usually fall under implied consent. This means that their consent is given even though they cannot physically do so - they would consent if they could. Only perform first aid if you are trained and feel comfortable with the situation. You should also always take steps to protect yourself, including using disposable gloves.

Dr Charles Sophy, MD, Adolescent Medicine, answeredYou can use first aid on strangers as long as you do so with caution. When rendering first aid to strangers, avoid direct contact with their blood. If not, use sanitized gloves, clean fabric or your clothing to protect you.
