👉 The videos you're referring to likely depict the release of toxic fumes or gases, often associated with industrial processes, chemical reactions, or malfunctioning equipment. These fumes can include harmful substances like carbon monoxide, sulfur dioxide, nitrogen oxides, and volatile organic compounds (VOCs), which pose significant health risks to humans and the environment. The visuals typically show plumes of smoke, hazy atmospheres, or chemical reactions that release noxious gases, often accompanied by sounds of alarms or sirens to indicate danger. Such videos are commonly used to raise awareness about industrial safety, environmental hazards, or to highlight the importance of proper ventilation and protective measures in workplaces where these fumes might be present.
