About 2.5 mg of aqueous sodium azide (or more specifically, about 5 mL of a 0.05% solution); symptoms appearing one week after exposure and worsening for several days (at least three); rash that looks like pimples or very small blisters and spreads for approximate site of exposure to surrounding area over the course of several days.
I'm trying to figure out the cause of an unexplained rash. Don't ask.|||Yes, azides can cause delayed reactions..........go find a doctor NOW!!|||Yes.
The seriousness of poisoning caused by sodium azide depends on the amount, route, and length of time of exposure, as well as the age and preexisting medical condition of the person exposed.
Breathing the gas that is formed from sodium azide causes the most harm, but ingesting (swallowing) sodium azide can be toxic as well.
People exposed to a small amount of sodium azide by breathing it, absorbing it through their skin, or eating foods that contain it may have some or all of the following symptoms within minutes:
Rapid breathing
Restlessness
Dizziness
Weakness
Headache
Nausea and vomiting
Rapid heart rate
Red eyes (gas or dust exposure)
Clear drainage from the nose (gas or dust exposure)
Cough (gas or dust exposure)
Skin burns and blisters (explosion or direct skin contact)
Exposure to a large amount of sodium azide by any route may cause these other health effects as well:
Convulsions
Low blood pressure
Slow heart rate
Loss of consciousness
Lung injury
Respiratory failure leading to death.
There is no specific antidote against sodium azide, only supportive care.
