Exposure to high level of nitrogen dioxide may lead to inflammation of the mucous membrane and the lower and upper respiratory tracts. [11] The symptoms of acute nitrogen dioxide poisoning is non-specific and have a semblance with ammonia gas poisoning, chlorine gas poisoning, and carbon monoxide poisoning.
Nitrogen dioxide is a reddish-brown gas with a pungent, acrid odor above 21.2 °C (70.2 °F; 294.3 K) and becomes a yellowish-brown liquid below 21.2 °C (70.2 °F; 294.3 K). It forms an equilibrium with its dimer , dinitrogen tetroxide ( N 2 O 4 ), and converts almost entirely to N 2 O 4 below −11.2 °C (11.8 °F; 261.9 K).
The term immediately dangerous to life or health (IDLH) is defined by the US National Institute for Occupational Safety and Health (NIOSH) as exposure to airborne contaminants that is "likely to cause death or immediate or delayed permanent adverse health effects or prevent escape from such an environment."

If you're going to wear one, “make sure it's not super-tight to the point that you can't breathe,” she says. “You should be able to breathe. You should be able to sit and stand comfortably.
The symbol represents a "third body", a molecular species that is required to carry away energy from the exothermic reaction 2.Equation 4 relates the concentrations of NO x and ozone, and is known as the Leighton relationship.
