I'm a bit concerned because my husband accidentally mixed bleach with a tile cleaner while cleaning the bathroom, and it caused a really strong smell. He left the bathroom and cleaned it again after about ten minutes, but since then, he's been coughing a bit and feeling some chest tightness. He also can't stop burping. He drank some Electral afterward, and his oxygen levels seem normal at 98. Should I be worried about this? What should we do next?

Your husband's symptoms, such as cough, chest tightness, and continuous burping, are likely due to inhalation of toxic fumes from the bleach and tile cleaner mixture; while his oxygen levels are normal, it's essential to monitor his condition closely and seek medical attention immediately if symptoms worsen or if he experiences difficulty breathing, severe headache, or dizziness; consider consulting a doctor or visiting an emergency room for further evaluation and guidance.
