If you inhalation urethane what are the side effects?

Answer 1

Urethane, more properly called Polyurethane, is a solid. If cut, sawed or ground into particles small enough to inhale, the effects are likely to be irritation and sneezing or coughing to clear the material from the throat and nose. If the polyurethane was improperly made and contains unreacted residue of one of its components, an isocyanate, then other effects may be experienced. These are primarilly sensitization, so that Asthma and related conditions develope upon subsequent exposure to extremely small concentrations of isocyanate.
