Answer :
Final answer:
High-pressure accessory hoses used on wheeled extinguishers should be tested at 600 psi to ensure their reliability and safety in emergency situations. The correct answer is option b).
Explanation:
The question regarding the testing pressure of high-pressure accessory hoses used on wheeled extinguishers is focused on safety and maintenance standards within fire safety equipment. When it comes to testing these hoses, the standard requires that they be tested at a specific pressure to ensure their reliability and safety in emergency situations.
According to safety protocols and maintenance guidelines often adopted by fire safety equipment manufacturers and regulatory bodies, the standard testing pressure for high-pressure accessory hoses on wheeled extinguishers is 600 psi. This testing ensures that the hoses can withstand the operational pressures they might encounter during use without failing, thereby ensuring the safety of the operators and efficiency in firefighting efforts.
