Pkp Vs Plus 50 Flashcards
What is the primary use of High-Flow Purple-K?
Rapid knockdown of high-heat, fast-spreading fires
High-Flow Purple-K is specifically designed for situations where quick suppression is critical.
What is the key advantage of High-Flow Purple-K in fire suppression?
Superior chemical suppression: Potassium bicarbonate is 40% more effective per pound
This effectiveness is crucial in quickly extinguishing fires.
At what temperature does High-Flow Purple-K decompose?
212°F
This high heat resistance allows it to perform better in extreme conditions compared to Plus-Fifty C.
What are the limitations of High-Flow Purple-K?
- Short discharge time
- Lower UL rating
These limitations affect its practical use in certain scenarios.
What types of fires is High-Flow Purple-K best suited for?
- Transformer oil fires
- Flammable liquid pools (fuel spills)
- Industrial equipment fires
- Any situation requiring fast suppression
These scenarios benefit from its rapid knockdown capabilities.
What is the primary use of Plus-Fifty C?
Prolonged firefighting with sustained coverage
Plus-Fifty C is ideal for situations where longer discharge times are beneficial.
What is a key advantage of Plus-Fifty C?
Longer discharge time: Slower flow maintains agent application
This allows for more controlled firefighting efforts.
What is the decomposition temperature of Plus-Fifty C?
158°F
This lower heat tolerance limits its effectiveness in high-heat fires.
What are the limitations of Plus-Fifty C?
- Lower heat tolerance
- More residue
- Less knockdown power
These limitations can affect cleanup and overall effectiveness in certain fire situations.
What types of fires is Plus-Fifty C best suited for?
- Smaller Class B fires (low heat)
- Electrical panel fires (Class C)
- Confined spaces where longer discharge matters
These scenarios benefit from its prolonged application and lower intensity.
Which agent is more cost-effective?
Plus-Fifty C
Sodium bicarbonate used in Plus-Fifty C is cheaper and more widely available.
True or False: High-Flow Purple-K has a higher UL rating than Plus-Fifty C.
False
High-Flow Purple-K has a lower UL rating (20-B:C) compared to Plus-Fifty C (80-B:C).
Which agent is recommended for critical high-heat fires?
High-Flow Purple-K
It is ideal for rapid knockdown in scenarios such as transformer or flammable liquid fires.
Which agent should be chosen for extended coverage in lower-intensity fires?
Plus-Fifty C
It is preferable when longer discharge and UL-rated performance are important.
