Comprehensive Guide to Montana State Laws and Codes for Smoke Alarms, Carbon Monoxide Alarms, and Natural Gas Alarms

In Montana, state laws and local regulations set forth standards for the installation and maintenance of smoke alarms, carbon monoxide (CO) alarms, and natural gas alarms. This guide provides an in-depth overview of Montana’s requirements and codes related to these essential safety devices, ensuring residents can maintain compliance and protect their homes effectively.

1. Smoke Alarms

Montana Code: Montana Code Annotated (MCA) Title 50, Chapter 60 and the Montana Residential Code

Installation Requirements:

  • New Construction: According to Montana’s codes, smoke alarms must be installed in every bedroom, outside each sleeping area, and on every level of the home, including basements. These requirements align with the International Residential Code (IRC) standards as adopted by the Montana Residential Code.
  • Existing Homes: For existing homes, smoke alarms should be updated to meet current standards if they are older than 10 years. Smoke alarms must have a sealed, non-removable battery with a minimum lifespan of 10 years.

Power Source:

  • Smoke alarms must be hardwired with a battery backup or powered by a sealed, non-removable battery with a lifespan of 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:

  • Ensure smoke alarms are interconnected so that all alarms sound simultaneously when one detects smoke.
  • If a smoke alarm activates, evacuate immediately and contact emergency services.

2. Carbon Monoxide Alarms

Montana Code: Montana Code Annotated (MCA) Title 50, Chapter 60 and the Montana Residential Code

Installation Requirements:

  • New Construction and Existing Homes: CO alarms are required outside each sleeping area and on every level of the home, particularly in homes with fuel-burning appliances or an attached garage. This is crucial to prevent CO poisoning and ensure safety.

Power Source:

  • CO alarms must be either 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 test them frequently.
  • 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

Montana Code: Local Building Codes and Utility Regulations

Installation Requirements:

  • New and Existing Homes: While Montana does not have a statewide mandate for natural gas alarms, 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 guidelines, and replace the entire unit based on the manufacturer’s timeline.

Key Points:

  • Natural gas alarms are essential 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.

Local Ordinances and Updates

Billings:

  • Installation Requirements: In Billings, smoke alarms must be installed in every bedroom, outside each sleeping area, and on every level of the home, including basements. CO alarms are required outside each sleeping area and on every level of the home. Local codes may also provide additional guidelines for natural gas alarms.
  • Power Source: Both smoke and CO alarms must be hardwired with a battery backup or powered by a sealed battery with a lifespan of at least 10 years.
  • Natural Gas Alarms: Billings may have specific local requirements for natural gas alarms depending on the area and the building's age. Consult local regulations for the most current requirements.

Conclusion

Montana’s regulations for smoke alarms, carbon monoxide alarms, and natural gas alarms are designed to safeguard residents and enhance home safety.
