Heat Emergency Protocol — El Niño Extreme Heat Response
Heat Emergency Protocol
When extreme heat hits, here’s how to protect residents and building systems.
Understanding the Threat
Wet-Bulb Temperature (WBT) combines heat + humidity. When WBT reaches 31-35°C with 90%+ humidity, the human body literally cannot cool itself through sweating.
| WBT Level | Risk Level | Symptoms |
|---|---|---|
| 26-28°C | Warning | Discomfort, fatigue |
| 29-31°C | Danger | Heat exhaustion, dizziness |
| 31-33°C | Severe | Heat stroke risk, rapid onset |
| 34°C+ | Critical | Life-threatening within hours |
Heat Emergency Levels
Level 1: Heat Warning (WBT 28-30°C)
- MO issues WhatsApp alert to all residents
- Pool hours may be restricted (safety concern)
- Outdoor workers reduce hours during peak heat (11AM-3PM)
- Residents advised to stay hydrated, limit outdoor activity
Level 2: Heat Danger (WBT 31-33°C)
- Immediate Actions:
- Check on vulnerable residents (elderly, those with medical conditions)
- Common areas maintain AC, check backup systems
- Pool closes if water temperature exceeds safe levels
- Residents advised: minimize outdoor activity, check on elderly neighbors
Level 3: Heat Emergency (WBT 33°C+)
- Emergency Response:
- Establish building-wide cooling center (lobby, community hall)
- MO prioritizes AC for vulnerable residents
- All outdoor work suspended
- Emergency contacts activated for medical needs
- Coordinate with security for building-wide welfare checks
Vulnerable Resident Registry
Residents can opt-in to priority check-ins during heat events:
- Elderly living alone
- Residents with heart/lung conditions
- Those with medical appointments
- Residents with power-sensitive medical equipment
Privacy note: Opt-in only, data not shared with management office, used solely for emergency welfare checks.
Building System Protocols
Cooling Systems
- Pre-emptive: Schedule maintenance before peak season
- During: Monitor common area cooling loads
- Emergency: If main AC fails, prioritize cooling for vulnerable residents
Power Systems
- Monitor: Track transformer load during peak hours
- Surge Protection: Ensure building-wide surge protection is active
- Backup: Test genset capability before El Niño season
Communication Protocol
Daily Updates (During Heat Events)
- Morning: Current WBT reading, forecast for day
- Afternoon: Building system status, emergency alerts
- Evening: Next day outlook, recovery protocols
Emergency Contacts
| Role | Contact | Hours |
|---|---|---|
| Security (24/7) | 03-7660 4754 | Always |
| Management Office | 03-7660 4752 | 8AM-5PM |
| Medical Emergency | 999 | Always |
| TNB (Power) | 1-300-88-6444 | Always |
Resident Self-Care Checklist
- Stay hydrated (aim for 2-3L water/day during heat)
- Keep blinds closed during peak heat hours
- Use exhaust fans in kitchen to prevent heat buildup
- Check on elderly neighbors daily
- Know your building’s cooling center location
- Have emergency contact numbers handy
