Class 5 Boiler Practice Exam

Are boilers under 400k BTU exempt from CSD-1 requirements?

1. True

2. False

3. Only if they are older than 10 years

4. Only if they are used for residential purposes

The correct answer is: False

Boilers under 400,000 BTU are not exempt from CSD-1 requirements. CSD-1, which stands for the Code for Safety Devices for Automatically Fired Boilers, sets standards for the safety and operational reliability of boilers. These requirements apply regardless of the boiler's BTU rating. The reasoning behind this is rooted in safety; even smaller boilers can present significant hazards if not properly equipped with safety devices. CSD-1 ensures that all automatically fired boilers, regardless of size, adhere to specific safety protocols to prevent hazards such as explosions or uncontrolled boiler operation. The other options introduce specific scenarios, such as age or usage type, which do not alter the fundamental requirement that all boilers, independent of size, must comply with safety standards set forth by CSD-1. Safety is paramount across all boiler operations, hence the necessity for these regulations to apply universally.
