This place does not cover:
Attention is drawn to the following places, which may be of interest for search:
Methods to fight fires (e.g. by inerting) |
In this place, the following terms or expressions are used with the meaning indicated:
Intumescent | permanently changing properties under the influence of high temperatures, best known example is graphite, which expands when subjected to large amounts of heat, thus forming a layer which isolates one side from the heat on the other side |
This place covers:
Devices which physically prevent fire from passing the point where the device is installed.
This place does not cover:
Layered materials | |
Fire proof paints or coatings | |
Fireproofing materials |
Attention is drawn to the following places, which may be of interest for search:
Emergency operation for doors and windows | |
Curtains | |
Devices for use where pipes or similar pass through walls or partitions | |
Air-flow control members for ventilation, air-conditioning or similar |
Attention is drawn to the following places, which may be of interest for search:
Laminated safety glass or glazing with intumescent layers for fire protection | |
Fireproof doors or similar closures, or adaptations of fixed constructions therefor, with sealing arrangements between the door or window and its frame, e.g. intumescent seals specially adapted therefor | |
Flameproof or explosion-proof arrangements structurally associated with lighting devices using intumescent material, i.e. using materials which swells up as a result of heat exposure |
This place covers:
Devices and Methods which are used for specific circumstances or in specific places.
This place does not cover:
Fire fighting in oil wells | |
Prevention of fires in mines or tunnels | |
In turbines or jet engines | |
For nuclear reactors |
Attention is drawn to the following places, which may be of interest for search:
Extinguishing devices for cigarettes, pipes, ash-trays, etc... | |
Christmas tree decorations including fire fighting/fire prevention means | |
Floating covers for liquids in large containers | |
Prevention of fire due to dust build-up | |
Forming a firebreak device for pipes, cables or similar passing through walls or partitions | |
Extinguishing-devices, e.g. for blowing-out or snuffing candle flames | |
Heat or fire protective means for installations of cables or lines in buildings or vehicles |
This place covers:
Devices which stop the expansion of pressure waves or fires by their constructional features, e.g. by cooling down the passing gas, thus suffocating the flame.
This place does not cover:
Pressure relief valves/safety valves |
This place covers:
Devices and methods which allow the preparing of extinguishants directly before use, e.g. by mixing water and additives on their way to the fire-extinguishing nozzle.
This place does not cover:
Nozzles for fire-extinguishing | |
Chemical composition of fire extinguishants |
Attention is drawn to the following places, which may be of interest for search:
Flow mixers for foam |
This place does not cover:
Portable fire extinguisher with manually-operated pumps | |
Filling of pressurized vessels |
Attention is drawn to the following places, which may be of interest for search:
Pressurized containers/vessels | |
Mounting devices for pressurized containers |
This place does not cover:
Supporting devices for portable extinguishers |
Attention is drawn to the following places, which may be of interest for search:
Knapsacks, carrying-frames, pack-frames carried on the body |
Attention is drawn to the following places, which may be of interest for search:
Launchers for projectiles | |
Explosive charges in projectiles |
This place covers:
Vehicles or platforms floating in water adapted to fight fires (on other ships or platforms).
This place does not cover:
Fire extinguishing in ships or other vessels floating in water |
Attention is drawn to the following places, which may be of interest for search:
Fire extinguishing in ships |
This place covers:
Devices which are used to deliver the fire-extinguishants to the point where they are needed.
Attention is drawn to the following places, which may be of interest for search:
Hose accessories specific to fire fighting | |
Fire-extinguishing sprinklers with integrated fire sensor (e.g. glass bulb) | |
Nozzles | |
Hydrants in streets | |
Water cannons |
Attention is drawn to the following places, which may be of interest for search:
Making tubes of specials shapes, e.g. T-splits, connecting pieces | |
Reels for filamentary or thin materials | |
Devices for coupling hoses |
Since most devices for collecting fire hoses do this by ensuring that the fire hose is empty (thus dry), devices for collecting hoses are in A62C 33/02.
This place does not cover:
Devices for forming water curtains | |
Delivery of fire-extinguishing material | |
Control of fire fighting equipment |
Attention is drawn to the following places, which may be of interest for search:

Fire alarms without automatic activation |
This place covers:
Special methods of fire fighting (e.g. inerting), training methods and equipment for training fire-fighting as well as any devices for fire-fighting which cannot be classified in other groups.
This place does not cover:
Heat-resistant garments |
If devices use certain methods which are represented by a subgroup in A62B 99/00, they will be classified in the respective device group and in the respective method group. For example, devices to inert luggage compartments of airplanes will be classified in A62C 3/08 and A62C 99/0018.
