Handle ideation sketched from design requirements that include: the ability to hold with two hands, intuition through product semantics and accessibility of key operational features when in use.
One of the major design considerations of the fire extinguisher is the usability factor.
The device requires less hand strength to operate compared to the existing lever mechanism. The semantics illustrate how the product is used and handled.

This design uses an adapted version of the aerosol can mechanism to allow the user the easiest method of operation.
The main body is made from a die-pressed aluminium alloy. The handle and nozzle is injection moulded from thermosetting, heat-resistant polyurethane. The internal mechanism components are made of brass.

Unlike fire extinguishers today, the handle can be held at two points allowing for a better distribution of weight. The handle includes a release button and sliding lock, which all have symbols to show its action. At the top of the handle is an instruction to aim at the base of the fire as this is a ‘must do’ which many are unaware of.
