What are the two general types of sprinkler coverage?

• A. Complete & partial sprinkler coverage
• B. Wet & dry coverage
• C. Local & global coverage
• D. Primary & secondary coverage

Answer: (A)

The concept here is how sprinkler spray protects a space. There are two basic outcomes: complete coverage, where every part of the protected area receives adequate sprinkler discharge, and partial coverage, where some zones aren’t fully covered due to layout, obstructions, or spacing limitations. In practice, you aim for complete coverage so that a fire is reached quickly no matter where it starts in the area. If obstacles like walls, shelves, or high ceilings interrupt the spray pattern, you end up with partial coverage, which may require adding more heads or redesigning placement to fill the gaps. The other terms in the choices describe different ideas (like the state of the piping or notions of scope) and don’t capture the general way coverage is classified.
