Sonic Blast Mini Signal Horn - with Velcro Strap

Over the years, HFC-134a has been a common propellant used for horns as it is a non-volatile organic compound (non-VOC) and is also non-flammable.
With the EPA ban on the use of HFC-134a as a horn propellant, Falcon has launched a line of signal horn products that use alternative propellants.

The new HMO1234ze used in sonic blast horns is a specially formulated non-flammable propellant that has an ultra-low global warming potential (GWP). It has a 99.5% lower GWP than HFC-134a and is ideal for uses where flammability is a concern, including boating, manufacturing plants, construction sites, etc.
It is not considered HAZMAT, and needs no special documentation.

This 1 oz Sonic Blast horn provides up to 12 blasts per can.
