Check What Matters When Choosing a Fire Extinguisher for Home

The Busan Sasang Fire Station's 2026 guidance suggests at least one per household, and a home that uses several floors should also check the per-floor standard.

What do you check first to decide how many to prepare?

The Busan Sasang Fire Station's 2026 material describes extinguishers and single-station smoke alarms as separate residential fire safety equipment. Having a detector installed doesn't let you skip preparing an extinguisher.

The Incheon Fire and Disaster Headquarters' 2017 guidance states the number of extinguishers as at least one per household and per floor. That material covers detached houses, multi-household houses, row houses, and multi-unit houses. Write down your building type and the floors you use, and confirm the current local installation standard with your local fire station.

How do agent weight and gross weight differ?

Agent weight is the weight of the extinguishing agent in the container, and gross weight is the weight of the whole product. Daedong Fire Safety's official page for the MAX 3.3KG lists the two values separately. Don't guess at the weight you'll have to lift from the number in the name alone.

This is based on Daedong Fire Safety's published specs, checked on 2026-10-08. The table is just one model's example of how to read a spec sheet. It isn't a table for ranking products, and it doesn't mean the same values apply to other models.

How do the two candidates differ in agent weight and overall size?

Based on Daedong Fire Safety's official specs for the stainless steel 3.3KG and the domestic-made 4.5KG, checked on 2026-10-08. These are different models from the MAX 3.3KG example above. Even though the amount of agent differs, the two models have the same official fire-fighting capacity listing. Check prices and what's in the box through the links, as of the check date.

If the stainless steel container and the smaller gross weight matter, compare the 3.3KG specs; if the amount of agent comes first, compare the 4.5KG. The two models differ in height and width, so measure the spot where you'll put it in advance. For places that need an agent or class other than ABC powder, don't apply these two candidates as they are; ask your local fire station first what type is required.

What information do you cross-check before you order?

First check that the manufacturer and model name of the product on sale match the official spec sheet. Then compare the number you need, the type of agent, the fire-fighting capacity, and the gross weight. If you can't confirm the model name, don't treat a product as the same one just because it looks similar.

The fire station material in this article alone can't pick a specific product that suits every home. If your building type or per-floor layout is unclear, finish checking the installation standard first.

What goes on your home checklist?

Write down the four items below before you order, and it's easier to compare against the sales page.

• Your building type and the floors you use
• The number of extinguishers you've prepared per floor
• The manufacturer, model name, and address of the official spec sheet
• Whether you've checked agent weight and gross weight separately

An extinguisher is equipment for the initial response. This article is not guidance on firefighting procedure or on judging whether to keep fighting a fire at the scene. The sources were checked on October 8, 2026.
