This comprehensive guide provides an overview of New Hampshire’s regulations and standards for these critical safety devices, helping residents stay compliant and protect their homes effectively.
1. Smoke Alarms
New Hampshire Code: New Hampshire RSA 153 and the New Hampshire State Building Code
Installation Requirements:
- New Construction: In new homes, smoke alarms must be installed in every bedroom, outside each sleeping area, and on every level of the home, including basements. These requirements adhere to the standards set by the International Residential Code (IRC) as adopted by the New Hampshire State Building Code.
- Existing Homes: For existing homes, smoke alarms should be updated if they are older than 10 years. New smoke alarms should feature a sealed, non-removable battery with a minimum lifespan of 10 years.
Power Source:
- Smoke alarms must be either hardwired with a battery backup or powered by a sealed, non-removable battery that lasts at least 10 years.
Maintenance:
- Test smoke alarms monthly, replace batteries annually if the unit is not equipped with a sealed battery, and replace the entire smoke alarm unit every 10 years.
Key Points:
- Smoke alarms should be interconnected so that all alarms in the home sound when one detects smoke.
- If a smoke alarm activates, evacuate the home immediately and call emergency services.
2. Carbon Monoxide Alarms
New Hampshire Code: New Hampshire RSA 153 and the New Hampshire State Building Code
Installation Requirements:
- New Construction and Existing Homes: CO alarms must be installed outside each sleeping area and on every level of the home, especially if the home has fuel-burning appliances or an attached garage. This is essential for preventing CO poisoning and ensuring the safety of residents.
Power Source:
- CO alarms should be hardwired with a battery backup or powered by a long-life, non-removable battery. Combination smoke and CO alarms are acceptable if they meet both smoke and CO alarm requirements.
Maintenance:
- Regularly test CO alarms, replace batteries as needed, and replace the entire unit every 5 to 7 years according to the manufacturer’s recommendations.
Key Points:
- Install CO alarms according to the manufacturer’s instructions and ensure regular testing.
- Symptoms of CO poisoning include headache, dizziness, and nausea. If CO poisoning is suspected, seek fresh air immediately and call emergency services.
3. Natural Gas Alarms
New Hampshire Code: Local Building Codes and Utility Regulations
Installation Requirements:
- New and Existing Homes: New Hampshire does not have a statewide mandate for natural gas alarms, but local building codes or utility regulations may require their installation. It is advisable to install natural gas alarms near potential sources of gas leaks, such as gas appliances or utility rooms.
Power Source:
- Natural gas alarms should be hardwired into the home’s electrical system or powered by a long-life battery.
Maintenance:
- Regularly test natural gas alarms, replace batteries according to the manufacturer’s recommendations, and replace the entire unit based on the manufacturer’s timeline.
Key Points:
- Natural gas alarms are crucial for detecting leaks that could result in fires or explosions. Ensure compliance with local codes for proper installation.
- If a gas leak is suspected, evacuate the home immediately, avoid using electrical switches or open flames, and contact your gas utility provider or emergency services.
