A winter service vehicle (WSV), or snow removal vehicle, is a vehicle specially designed or adapted to clear thoroughfares of ice and snow. [ 1 ] [ 2 ] [ 3 ] Winter service vehicles are usually based on a dump truck chassis , with adaptations allowing them to carry specially designed snow removal equipment.
An Aeroflot Airbus A330 being de-iced at Sheremetyevo International Airport Econ Salt Spreader. De-icing is the process of removing snow, ice or frost from a surface. Anti-icing is the application of chemicals that not only de-ice but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier.
Windshield washer fluid being poured into a vehicle's storage tank, or reservoir. Windshield washer fluid (also called windshield wiper fluid, wiper fluid, screen wash (in the UK), or washer fluid) is a fluid for motor vehicles that is used in cleaning the windshield with the windshield wiper while the vehicle is being driven.
Owners of large buildings or building complexes generally have mechanized snow-removal equipment, but individual house owners mostly clean the sidewalk with hand tools. One example of the longstanding debate over the obligation of snow removal comes from the Czech Republic. In Prague, evidence of such a duty is documented since 1838. [13]
In 1923, the brothers Hans and Even Øveraasen of Norway constructed an early snowplow for use on cars. This proved to be the start of a tradition in snow-clearing equipment for roads, railways [14] and airports, as well as the foundation of the company Øveraasen Snow Removal Systems. [citation needed]

Nozzle design is the most significant factor in carbon dioxide snow cleaning performance, affecting the size and velocity of the dry ice particles. [ 4 ] : 277–278 Variations in nozzle design have been developed by W.H. Whitlock, L.L. Layden, Applied Surface Technologies, and Sierra Systems Group.
Air-aspirating nozzles use an opening in the cone shaped nozzle to inject air into a stream of water based foam (CAFS/AFFF/FFFP) to make the concentrate "foam up". Most commonly found on foam extinguishers and foam handlines. Swirl nozzles inject the liquid in tangentially, and it spirals into the center and then exits through the central hole ...
