Smoke or chemical inhalation
Do not mix ammonia and bleach together, as it can create toxic chloramine vapors that can be harmful when inhaled. If accidentally mixed, immediately leave the area to get fresh air, ventilate the space, and seek medical help if experiencing symptoms like difficulty breathing, coughing, or watery eyes.
Evacuate the area immediately to fresh air and avoid inhaling the fumes. Ventilate the space by opening windows and call for help, as inhaling the fumes can be toxic and harmful to your health. Do not touch the mixture or try to clean it up yourself as it can be dangerous.
Immediately evacuate the area and call emergency services. Do not attempt to clean it yourself, as mixing ammonia and bleach creates toxic fumes that can be harmful or fatal. Let trained professionals with the proper equipment handle the spill.
When it burns gas a gas fire produces hot invisible poisonous fumes that include the odorless gas Carbon Monoxide. Those fumes must be vented to the outside of the building using a good chimney or a properly designed flue pipe otherwise they can easily kill you.If a gas fire is properly set up it should not produce any visible smoke at all so if your gas fire is producing smoke you must urgently call a licensed gas fitter to fix the gas firefor you.If visible sooty smoke comes off a gas fire that could be as dangerous to your health as the normal odorless and invisible fumes produced by a properly set up gas fire which vents them through a proper flue pipe or chimney.
Really you should call 911 and wait for toxic waste cleaners to clean it up.
If you mean Scuba tanks, call a dive shop, if you mean emergency breathing tanks, call your local Fire Co.
