What extinguishing agent was discontinued in 1994?
On January 1, 1994, Halon production ceases in compliance with the Montreal Protocol and the U.S. Environmental Protection Agency. The use of Halons has been reducing over the years, but there is still demand for it for specific applications.
What is the most common fire extinguishing agent?
Today’s most widely used type of fire extinguisher is the multipurpose dry chemical that is effective on Class A, B, and C fires. This agent also works by creating a barrier between the oxygen element and the fuel element on Class A fires. Ordinary dry chemical is for Class B & C fires only.

What is the difference between halon and halotron?
Halotron is a clean, non-conductive gaseous agent that is an excellent replacement for Halon 1211 extinguishers because it has a lower environmental impact and leaves no residue. Halotron interrupts the chemical chain reaction and cools the fuel to extinguish the fire.
What are the three techniques used to fight fires?
Fire Fighting Techniques
- Indirect attack. Aimed at the ceiling, the water drops down and extinguishes the fire from above.
- Direct attack. Perhaps the most widely known technique – this suffocates the flames as the water is aimed at the base of the fire.

The F – 16 is a cheaper, lighter, slightly less powerful aircraft, but was designed with an emphasis on ease of maintenance and maneuverability.
Does the Air Force still use F-15?
The Air Force hasn’t bought an F – 15 in over a decade. Boeing is getting its St. Louis plant ready to build them just in case. Fight in Congress could pit upgraded legacy fighter against modern stealth F -35 jet.
