There is no safe size for a gas leak. Even a small leak can create serious risks over time, including fire hazards, explosions, and exposure to harmful gases.
Small leaks are often harder to detect and may go unnoticed for longer periods. This can allow gas to build up in enclosed areas, increasing the risk of ignition or health symptoms like headaches, dizziness, or fatigue.
Because of these risks, any suspected gas leak should be treated as urgent. Do not try to locate or repair the leak yourself. Leave your home and have a qualified technician inspect and repair the issue to ensure your system is safe.
