About BA Control Board

Adding a New Entry:

• Enter the firefighter's name
• Select the team number (1-20) - this groups firefighters working together
• Input the current cylinder pressure in bar
• Add any relevant comments
• Choose to either "Add Entry" (for immediate entry) or "Stage Entry" (to prepare crew for later entry)

Team Management:

• Multiple firefighters can be assigned to the same team number (e.g., both "John" and "Sarah" can be assigned to Team 1)
• Team members are grouped together in the display for easy monitoring
• The system automatically prioritizes teams based on their most critical member's status
• Teams are sorted by their highest priority member - if one team member reaches whistle time, the entire team is flagged for recall
• This ensures teams stay together and the weakest link determines when the team should exit

Managing Staged Crews:

• Staged entries appear in a separate section and are not actively monitored
• When a staged crew is ready to enter, click "Enter" - this sets their entry time to now and begins active monitoring
• This allows you to prepare multiple crews in advance and activate them when they actually enter the hazardous area

Monitoring Air Supply:

• The system automatically calculates air depletion time based on pressure
• Countdown timers show time remaining until whistle time (6 minutes before empty)
• Entries turn red and show "OVERDUE" when past their calculated empty time
• Audio alerts notify when entries become overdue
• Click on any active operator row to update their current pressure and comments during radio checks
• Updating pressure automatically recalculates exit times based on current air consumption

Additional Features:

• Download operational history in CSV or PDF format
• Clear all entries when operations are complete

• Visual Alerts: Overdue entries are highlighted in red
• Audio Notifications: Sound alerts for overdue conditions
• Real-time Monitoring: Countdown timers update every second
• Pressure-based Calculations: Accurate air supply estimations
• Whistle Time Warning: 6-minute safety buffer before calculated empty time

• Entry Time: When the firefighter entered the hazardous area
• Pressure: Current cylinder pressure in bar
• Minutes to Empty: Calculated air supply duration
• Whistle Time: Time when safety signal should be given
• Time Remaining: Countdown to whistle time (MM:SS format)

Air supply calculations are based on the CFA BA Control Board reference data for 300 bar cylinders:

Whistle time is calculated as 6 minutes before the projected empty time, following CFA protocols.
