What to do when accidentally inhale WD-40?
Inhalation of vapors can cause irritation, nausea, and headache. Ingestion can cause vomiting and diarrhea. In some cases, inhalation or ingestion can cause severe lung damage. People with preexisting respiratory conditions such as COPD or asthma can have those conditions worsen after inhaling WD-40. Contact a local poison control center or urgent care center.
