Flammable aerosols classification for spray aerosols and foam aerosols are different. Aerosolsare suspensions of liquid and solid particles in the atmosphere, excluding clouds and precipitation. The aerosol particle sizes range from 10−4to 10 μm, falling under the following broad categories: sulfates, black carbon, organic carbon, dust, and sea salt. These are all aerosols we constantly encounter when we live in an urban environment. We call them aerosols of anthropogenic origin. Hardly anyplace in the world is free of anthropogenic aerosols, and we inhale them continuously. But aerosols also originate in nature: fog, sand, forest exudates, and sea spray are just a few examples.

Aer­o­sols are sus­pen­sions of fine solid particles or li­quid droplets in a gas. Clouds, for ex­ample, are aer­o­sols be­cause they con­sist of wa­ter droplets dis­persed in the air. There are a few types of aerosols — according to National Geographic, there are primary aerosols, which include anything that comes from the earth's surface, including dust, soot, or sea salt. Then there are secondary aerosols, which form when organic compounds collide, such as organic plant matter, or other materials, that contribute to haze. Aerosols are a part of air pollution from cars, power plants, and factories that burn fossil fuels. Some aerosols are released into the atmosphere, others are made in the atmosphere.

Aerosols are particles that are suspended in the air. When humans breathe, talk, sing, cough or sneeze, the emitted respiratory droplets mix in the surrounding air and form an aerosol. Because The global pandemic of COVID-19 has been associated with infections and deaths among health-care workers. This Viewpoint of infectious aerosols is intended to inform appropriate infection control measures to protect health-care workers.
