https://en.wikipedia.org/wiki/Sodium_azide
Sodium azide is the inorganic compound with the formula NaN3. This colorless salt is the gas-forming component in legacy[citation needed] car airbag systems. It is used for the preparation of other azide compounds. It is an ionic substance, is highly soluble in water and is very acutely poisonous.[5]

The Reagent Solution contains a harmful chemical (see table below). If the solution
contacts the skin or eye, flush with copious amounts of water. If irritation persists, seek

Sodium azide, used mainly as a preservative in aqueous laboratory reagents and biologic fluids and as a fuel in automobile airbag gas generants, has caused deaths for decades. Its exposure potential for the general population increases as the use of airbags increase. In order to characterize the known health effects of sodium azide in humans and the circumstances of their exposure, the authors conducted a systematic review of the literature from 1927 to 2002 on human exposure to sodium azide and its health effects. The most commonly reported health effect from azide exposure is hypotension, almost independent of route of exposure. Most industrial exposures are by inhalation. Most laboratory exposures or suicide attempts are by ingestion. Most of the reported cases involved persons working in laboratories. The time between exposure and detection of hypotension can predict outcome. Fatal doses occur with exposures of >or=700 mg (10 mg/kg). Nonlethal doses ranged from 0.3 to 150 mg (0.004 to 2 mg/kg).

What about repeated exposure to micro doses, right inside the nose?
