Table: Interpreting Pressure Gauge Readings
| Needle Position | Pressure Status | Refill Required |
|---|---|---|
| Within green/blue zone | Optimal pressure | No |
| Below optimal range | Low pressure | Yes |
| In red zone | Severely low pressure | Yes, urgent refill required |
Extinguishing Agent Exhaustion: When to Refill Extinguishers
Fire extinguishers are an essential part of fire safety and should be regularly inspected and maintained to ensure they are in good working order. One of the most important aspects of extinguisher maintenance is refilling the extinguishing agent when it has been exhausted.
