Fire extinguishers come in varying sizes, indicating the amount of fire extinguishing agent it holds. While fire extinguishers can go up 350 pounds in size, the most common sizing options for portable fire extinguishers are 5-pound, 10-pound, or 20-pound.
The size is an important factor in determining if you have enough fire extinguishers because you need to be sure you have sufficient fire extinguishing agent to address a fire emergency within a specified space. For example, a 5-pound fire extinguisher would not be appropriate for a large commercial space. So, it’s not just how many extinguishers you need, but also the right size.
The physical ability of employees to use a fire extinguisher should also be considered. For this reason, many building owners choose two 5-pound extinguishers over one 10-pound.
