Fire suppression systems that use FM-200 or CO2 can be used instead of systems that use Halon. When it comes to putting out fires, these systems have some similarities, but there are also some important differences.

What is FM-200?
HFC-227ea is used to put out fires in FM-200 systems. These systems work quickly, don’t hurt the ozone layer, and don’t conduct electricity. FM-200 is a clean agent that can put out Class A, Class B, and Class C fires. It is a clear, odorless substance that doesn’t leave any residue and cuts down on downtime. This system can be used in places where people are.

Applications where FM-200 systems are found:

  • Data centers
  • Telecommunication facilities
  • Military applications
  • Computer rooms
  • Control rooms
  • Museums
  • Historical archive storage
  • Art galleries
  • Pharmaceutical and medical facilities
  • Record storage facilities

What is CO2 Fire Suppression?

CO2 is a system for putting out fires that uses carbon dioxide to reduce the amount of oxygen in space to a point where fires can no longer happen. A CO2 fire suppression system is good for the environment, works quickly, and doesn’t conduct electricity. CO2 systems leave behind no residue, cause no damage to sensitive equipment and require no clean-up. These systems can be used to fight Class A, B, and C fires, but they are not safe to use in areas where people are present.

Applications where CO2 systems are used:

  • Power Plants
  • Metal Production and Processing
  • Printing Facilities
  • Automotive Plants
  • Electronics Operations
  • Electronics/Computer Production
  • Research Facilities
  • Storage Facilities

Factors to Consider When Choosing

Is the Area Occupied?
If your space is used most of the time, an FM-200 system might be safer. CO2 fire suppression should not be used in places where people are, because high levels of CO2 can make people lose consciousness and even kill them. CO2 fire suppression may be a good choice if the area that needs fire protection is usually empty.

How Much Space is Available?
Most of the time, the cylinders for a CO2 fire suppression system take up more space than the cylinders for an FM-200 system. If there isn’t much space where you live, FM-200 might be a better choice.

What is the Cost of Each System?
A CO2 system and an FM-200 system may have different prices. Talk to a fire protection contractor to find out which system will work best for your needs and save you the most money.
