Oxygen tent. An infant placed under an oxygen tent. An oxygen tent consists of a canopy placed over the head and shoulders, or over the entire body of a patient to provide oxygen at a higher level than normal. Some devices cover only a part of the face. Oxygen tents are sometimes confused with altitude tents as used by athletes and those ...
Respiratory protective equipment (RPE) is a type of personal protective equipment designed to protect the wearer from a variety of airborne hazards in the form of gas, fume, mist, dust or vapour over the long or short term. Respirators filter the ambient air to remove harmful materials and atmosphere supplying breathing apparatus provides clean ...
Mist. Mist is a phenomenon caused by small droplets of water suspended in the cold air, usually by condensation. Physically, it is an example of a dispersion. It is most commonly seen where water vapor in warm, moist air meets sudden cooling, such as in exhaled air in the winter, or when throwing water onto the hot stove of a sauna.
Tent. A modern two-person, lightweight hiking dome tent; it is tied to rocks as there is nowhere to drive stakes on this rock shelf.

While smaller tents may be free-standing or attached to the ground, large tents ...
The international definition of fog is a visibility of less than 1 km (3,300 ft); mist is a visibility of between 1 km (0.62 mi) and 2 km (1.2 mi) and haze from 2 km (1.2 mi) to 5 km (3.1 mi). Fog and mist are generally assumed to be composed principally of water droplets, haze and smoke can be of smaller particle size.
Fumigation is a method of pest control or the removal of harmful microorganisms by completely filling an area with gaseous pesticides, or fumigants, to suffocate or poison the pests within. It is used to control pests in buildings (structural fumigation), soil, grain, and produce. Fumigation is also used during the processing of goods for ...
A katabatic wind (named from Ancient Greek κατάβασις (katábasis) 'descent') carries high-density air from a higher elevation down a slope under the force of gravity. Such winds are sometimes also called fall winds; the spelling catabatic winds[1] is also used. Katabatic winds can rush down elevated slopes at hurricane speeds, but most ...
Haze is traditionally an atmospheric phenomenon in which dust, smoke, and other dry particulates suspended in air obscure visibility and the clarity of the sky. The World Meteorological Organization manual of codes includes a classification of particulates causing horizontal obscuration into categories of fog, ice fog, steam fog, mist, haze ...
