I’ve never heard a commercial building make regular periodic noises like that. I started up large package boilers for large commercial buildings and our safety valves never sounded like that when they popped off. The sounds are very weird.
I’ve never heard it or heard of it; but that’s apparently what it was. The person filming the video and others who reported it said that what they saw was steam, not smoke.
