Fire Extinguisher Supply and Service in Bangladesh

Which extinguisher goes where?

Match the extinguisher to what will burn. Cutting tables, fabric stores and offices are mostly ordinary combustibles, where water, foam or ABC powder works. Electrical panels, server racks and generator controls need CO₂ or clean agent, which leave no residue and do not conduct. Kitchens with fryers need a wet chemical unit, and fuel stores need foam or powder.

Placement matters as much as type. NFPA 10 sets maximum travel distances and mounting heights so a person can reach one quickly. Extinguishers should sit on exit routes, near hazards but not so close that the fire blocks access, and clearly signed. A unit hidden behind stacked cartons is a common finding on factory audits.

Why is powder not always the right answer?

ABC dry powder is popular because one type covers most risks, and it is cheap. But it makes a dense cloud that cuts visibility in a small room, and the fine powder is corrosive to electronics and hard to clean from machinery. For sewing lines with electronic machines or for control rooms, CO₂ or foam is often a better first choice.

We size the mix of types to the floor, not to a single standard order. A typical production floor might combine foam or water units with CO₂ near panels, which makes the right extinguisher easy to grab and avoids unnecessary damage after a small fire.

What does servicing actually involve?

NFPA 10 sets three layers. A monthly visual check by your staff confirms each unit is in place, charged and undamaged. A yearly maintenance by a technician checks the mechanism, seals and agent. Periodic hydrostatic testing proves the cylinder can still hold pressure, at intervals that depend on the type, for example every five years for CO₂ and water units.

Dry powder stored-pressure units also need an internal examination at a set interval, longer than for CO₂, when the powder is emptied and replaced. We keep the dates for every unit in the register and tell you in advance which ones are due, so nothing lapses between audits and units rotate without leaving gaps on the floor.
