Why Oval for New Construction?
Regardless of which mounting option is selected, Oval low-profile extinguishers provide compelling advantages. These advantages are highlighted below:
Option 1: Surface Mounting

|||
Low-Profile Fire Extinguisher | Conventional Fire Extinguisher | |||
---|---|---|---|---|
Projection from Wall | 3″ (76mm) or 3-1/2″ (89mm) maximum, depending on model | At least 5″ (127mm) | ||
Accessibility | Meets all ADA and code requirements for accessibility | Does NOT meet accessibility requirements | ||
Corridor/Aisle Width | Minimizes loss of usable corridor and aisle width | Reduces usable corridor and aisle width by 5″ (127mm) or more | ||
Collision Hazard | Can create an obstacle and collision hazard in corridors and aisles (though less than conventional extinguishers) | Creates an obstacle and collision hazard in corridors and aisles | ||
Mounting | Uses swivel-type button hook that holds extinguisher securely on wall, even if bumped or pushed | Uses unreliable and potentially dangerous wall hook. Extinguisher can fall off wall if bumped. | ||
Appearance | Visually unappealing. Appearance is usually not acceptable in offices, healthcare facilities, hotels and public spaces. | Visually unappealing | ||
Ease of Installation | Fastest and easiest installation method | Fastest and easiest installation method | ||
Total Installed Cost | Lowest cost option for installing a fire extinguisher | Lowest cost option for installing a fire extinguisher |

Option 3: Semi-Recessed Cabinet with Fire Extinguisher Inside

Cabinets for Oval fire extinguishers can be fully recessed into a 3-5/8″ (92mm) partition wall. A semi-recessed cabinet is therefore never required for Oval extinguishers. This installation option is irrelevant with low-profile fire extinguishers. | Due to the size of conventional fire extinguishers, typical partition walls do not have sufficient depth to accommodate a fire extinguisher cabinet. The wall must be made deeper or the cabinet must project partially out from the wall. Use of such a semi-recessed cabinet is always a “make do” compromise since they are unsightly, create collision hazards, waste floor space and are expensive. |

Design Challenge | Due to the reduced depth of low-profile fire extinguishers, cabinets can be fully recessed into 3-5/8″ (92mm) partition walls. There is no need to add extra depth to walls, widen corridors or create alcoves to accomodate the extinguishers. | Cabinets for conventional fire extinguishers are too deep to be recessed into 3-5/8″ (92mm) partition walls. These cabinets therefore require adding extra depth to walls, widening corridors or creating alcoves just to accomodate the fire extinguishers. | ||
