Red Seal Sprinkler Fitter Practice Exam

Question: 1 / 400

Which hazard classification requires a special design for sprinklers?

Low hazard

High hazard

Ordinary hazard

High hazard areas are classified based on the potential for industrial processes that could lead to large fires or explosions. Sprinklers installed in these areas must be designed to operate effectively under more demanding conditions compared to ordinary hazards. These special designs often feature higher flow rates, increased pressure, and may incorporate specialized nozzle types or distributions to ensure complete coverage of the area.

For high hazard classifications, the risk of scenarios requiring rapid and extensive suppression systems is heightened, so the design must consider factors such as the types of materials present, the arrangement of systems, and potential fire load. This ensures that the sprinklers can deliver an adequate water supply capable of addressing intense and fast-spreading fires common in high hazard environments.
