Firefighting Straw
Overview
The firefighting straw (Korean: 소방 빨대) is an unofficial umbrella term for a tubular evacuation aid used at fire and disaster scenes to help people maintain breathing by avoiding smoke inhalation, or for an extension hose used to suction and supply firefighting water. It is not an official equipment name used by the National Fire Agency or the Korea Fire Institute (KFI); rather, it is closer to a colloquial expression that spread as field personnel, safety instructors, and the evacuation-product market intuitively referred to tubular equipment. Accordingly, in institutional documents, the principle is to use individual official names such as 'evacuation breathing aid,' 'suction hose,' 'water supply hose,' and 'smoke exhaust duct.'
Key details
Nature and origin of the term
Whereas 'fire hose' is an official item with specifications and test methods defined under the national type-approval system, 'firefighting straw' is a generic term with no specification code. It began with the image of sucking air or water through a thin, long tube like a straw, and spread through internet communities and safety-product advertisements. Because the same word can refer to completely different equipment depending on context, documents, contracts, and training materials must specify the equipment in question.
1) Evacuation breathing aid tube
This is the type most commonly called a 'firefighting straw.' It consists of a mouthpiece, a short stretchable tube, and filter material, and is sold for reducing particulate matter in smoke when breathing while crouching low in a burning building. However, a filter-type structure cannot produce oxygen in an oxygen-deficient environment, and carbon monoxide is a gas that binds to hemoglobin, so it is not removed by a particulate filter. In other words, like a wet towel, it is only an 'aid'; considering that smoke suffocation is the main cause of fire deaths, the effective means of extending evacuation time ultimately comes down to securing an emergency exit and moving quickly horizontally and vertically.
2) Extension hoses for water supply, suction, and smoke exhaust
The suction hose of a fire truck (the hose that draws water up from a water source) and strainer, the extension water-supply hose run into a building, and the positive-pressure smoke exhaust duct are also referred to in the field with a similar image. In particular, in large fires requiring entry into underground spaces or long-distance advancement, the number of hose extensions determines suppression speed, so friction loss and the choice of hose diameter and nozzle are treated as key practical variables.
3) Metaphorical usage
The expression 'straw' is used when criticizing a structure in which an organization or business only sucks up budget, personnel, and power, and the metaphor 'firefighting straw' sometimes appears in reference to disaster-response budgets or particular safety projects. In this case, it is not equipment but a political and administrative rhetoric about resource allocation, so it should not be mixed with descriptions of physical equipment.
Safety rules and misconceptions
In smoke, one should crouch as low as possible, touch the wall to check the direction of the emergency exit, and recognize that a wet towel or filter-type evacuation device cannot guarantee life in oxygen-deficient or carbon-monoxide environments. Filter-type products are prohibited for use in low-oxygen enclosed spaces, and smoke-protection masks (hood type) are also not self-contained breathing apparatuses. After evacuating, one must report the situation to 119 and must not re-enter.
Regulations and standards
Firefighting products are managed under the type-approval and product-inspection system under the Act on Installation and Management of Firefighting Facilities, and the performance-test standards and labeling of evacuation devices and smoke-protection masks must be checked. For low-cost 'straw-type' products on the market, it is safer to first confirm whether they are subject to type approval and whether test reports exist.
Recent trends
As awareness of suffocation risk grew after the 2024 Incheon Cheongna electric vehicle fire and subsequent fires in underground parking lots and high-rise buildings, demand for smoke-protection masks and evacuation breathing aids increased rapidly in 2024–2025. At the same time, consumer warnings about exaggerated performance claims for filter-type products and campaigns to verify KFI type-approved products expanded, and local governments are increasingly enacting ordinances recommending the placement of evacuation supplies in multi-use facilities and senior and child welfare facilities. In firefighting field operations, tubular equipment such as nozzles and cooling hoses for responding to battery fires and long-distance smoke exhaust equipment is being advanced, and extension water-supply technology suited to increasing high-rise and underground depths and the lightweighting of personal protective equipment are cited as major tasks for 2025.
