Which type of fire extinguisher is considered obsolete and should be removed from service?

• A. Soda Acid extinguishers
• B. Water Mist extinguishers
• C. ABC Dry Chemical extinguishers
• D. Halotron extinguishers

Answer: (A)

Soda acid extinguishers are considered obsolete primarily due to their limited effectiveness and potential hazards. These extinguishers operate by using a mixture of sodium bicarbonate and sulfuric acid to create a chemical reaction that produces carbon dioxide, which helps to extinguish fires. However, they have significant drawbacks, including a higher likelihood of leaving corrosive residues and being inefficient against certain types of fires. In addition, their use has been largely replaced by more effective and safer fire suppression options, such as ABC dry chemical extinguishers, water mist extinguishers, and halotron extinguishers which can address a wider variety of fire classes. As a result, most fire safety regulations and standards now categorize soda acid extinguishers as outdated and recommend their removal from service in favor of more modern and effective extinguishing agents.
