After swallowing cleaners, pesticides or medicines, do not induce vomiting; seek urgent help with the container, and flush exposed eyes or skin for at least 15 minutes
Do not induce vomiting after suspected poisoning; corrosive liquids can burn the esophagus again on the way up. Seek urgent poison-expert or medical guidance and take the container and instructions with you; call China's 120 for an emergency. Do not routinely give milk, egg white, food or drink for an unknown substance. Poison Control limits small amounts of water or milk to caustic or irritating exposures when the person is conscious, not convulsing and able to swallow. For skin or eye splashes, rinse with abundant clean water for at least 15 minutes, holding eyelids open and not rubbing. Mixing disinfectant with toilet cleaner can release chlorine gas.
What it takes
Free prevention steps: store cleaners, disinfectants, pesticides and medicines high out of children's reach or locked away. Never decant them into drink bottles.
What you may gain
China's CDC National Institute of Occupational Health and Poison Control describes four routes in its strong-acid/alkali-cleaner guidance. For ingestion, that cleaner-specific article advises an appropriate amount of milk or egg white, explicitly no induced vomiting, and prompt care with packaging/instructions to identify ingredients. This is a description of the original article, not general treatment for pesticide, medicine or unknown-substance ingestion; obtain substance-specific professional advice. For inhalation, move to good ventilation and loosen the collar; severe cough, shortness of breath or breathing difficulty needs immediate care. For skin contact, rinse abundantly for at least 15 minutes without splashing eyes or unaffected skin. For eyes, immediately irrigate with clean water or saline for at least 15 minutes while holding lids open so water reaches the eye and inner lids; do not rub, and go directly to ophthalmology afterward. Products below pH 3 include toilet cleaners, descalers, floor cleaners and stainless-steel brighteners; some powerful drain cleaners contain dilute sulfuric acid. Products above pH 11 include drain cleaners, strong kitchen degreasers, dishwasher powder, oxygen-cleaning powders and scouring powder. Mixing disinfectant with hydrochloric-acid toilet cleaner releases chlorine, causing severe cough and breathlessness and potentially threatening life.
Context & considerations
Grade B because the official educational material gives recognition and response steps without a quantified reduction in harm. Safety correction: the original generalized milk/egg-white advice from a strong-acid/alkali-cleaner article to cleaners, pesticides and medicines. That blanket recommendation has been removed; its original context is retained above, and current action follows the cited Poison Control conditions and professional advice. Vomiting corrosives can burn the esophagus a second time. If the substance is uncertain, the source advises bringing its container, instructions and any vomit to the hospital. Prevention is cheaper: store separately from food/drinks, tighten caps, discard empty containers and never reuse water bottles. Wear rubber gloves and goggles, ventilate and do not mix cleaner types. See carbon monoxide and thermal burns.
