🔍 Key Concepts

• Look for symbols that indicate control or release stations (where you operate the system), not just the extinguishing agent storage cylinders. • Note that on this chart different agents are marked by letters: CO₂, F (foam), P (powder/dry chemical), etc. • Compare how a releasing station is drawn for other fixed systems (like CO₂) and look for the matching style used for the dry chemical system.

💭 Think About

• First, identify which symbols on the sheet clearly represent dry chemical (powder) equipment rather than foam or CO₂. • Then, among those powder-related symbols, decide which one represents the place you stand to operate or release the system, rather than a tank, hose, or nozzle. • Compare the numbering and shapes of the symbols in the 40s group and see which one pairs logically with the CO₂ and foam releasing stations shown elsewhere on the sheet.

✅ Before You Answer

• Verify which letter on the symbols corresponds to dry chemical (powder) on this chart. • Check whether the candidate symbol shows cylinders vs. a control point or station with an operating device or reel. • Confirm that the style of the symbol you pick is consistent with how other releasing stations (for CO₂ or foam) are depicted on this same illustration.
