Chlorine poisoning: when to get help

Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.

  1. 1

    Is any of this happening now?

    Call 911

    Follow the discharge instructions given by the emergency department, poison center, or treating clinician.

    Rest and avoid smoke, vaping, aerosol sprays, and strong chemical fumes while breathing symptoms are settling.

    Call emergency services immediately for:

    • Severe or rapidly worsening breathing difficulty
    • Blue or gray lips or skin
    • Confusion, fainting, or inability to stay awake
    • Foamy or pink sputum
    • Collapse or loss of consciousness
    • A major industrial or enclosed-space exposure
    • Serious symptoms after swallowing a concentrated product

    And for anyone, someone who:

    • you believe has taken an overdose or swallowed something poisonous
    Other emergency signs, for anyone
    • Someone who is struggling to breathe, gasping, choking, or cannot get words out
    • Someone who has chest pain, tightness or pressure lasting more than a few minutes
    • Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
    • Someone who is unconscious, or cannot be woken
    • Someone who is bleeding heavily and it will not stop with firm pressure
    • Someone who has had a seizure that will not stop, or does not wake up afterwards
    • Someone who has lips or skin that look pale, blue, grey or blotchy
  2. 2

    Is any of this happening?

    Be seen today

    Seek prompt medical assessment after an exposure if symptoms are new, persistent, or worsening.

    This includes repeated coughing, wheezing, chest discomfort, vomiting, trouble swallowing, significant eye pain, or blurred vision.

  3. 3

    Does any of this apply?

    Book an appointment

    Routine medical follow-up is appropriate if cough, wheezing, chest tightness, unusual tiredness, or reduced exercise tolerance continues after the exposure.

    A clinician may check lung function and decide whether further testing or respiratory treatment is needed.

    Eye or skin burns may require follow-up with an eye specialist or burn-care team.

The article also says

Do not drive yourself if breathing is difficult, vision is affected, or you feel faint.

Symptoms can worsen during travel.
