Yes, a gas leak will often produce a strong and distinctive odor, resembling rotten eggs or sulfur to alert people to its presence. This smell is due to an additive in natural gas called mercaptan, which is specifically added for safety reasons to ensure leaks can be quickly identified. If you detect this smell, it's crucial to act immediately: do not use electronics or open flames, ventilate the area if possible, and evacuate. Then, contact your gas provider or emergency services from a safe distance to report the leak.
