What activities are prohibited in relation to fire protection sprinkler systems?

• A. Only installation.
• B. Planning, selling, installing, maintaining, or servicing a fire protection sprinkler system in violation of the chapter or its rules.
• C. Only selling.
• D. Only maintenance.

Answer: (B)

The key idea is that the regulations prohibit any of the listed activities if they’re done in violation of the chapter or its rules. Planning, selling, installing, maintaining, or servicing a fire protection sprinkler system are all subject to those rules, and engaging in any of them in a way that violates the chapter is prohibited. This broad approach ensures every stage of work on a sprinkler system is controlled for safety and compliance, not just a single task.

The other options are too narrow because they focus on just one activity (like installation, selling, or maintenance) and imply the others could be done in violation without penalty, which isn’t the case.
