A squadron reloading in 2020

Is it safe to stand in the path of the drops like that?

I'd be more concerned about the fish than the drops.

It's usually just water or coloured water. Sometimes it has foaming agents, wetting agents, and other fun chemicals mixed in which are toxic.

Not when they load from a lake like these do. Then it's whatever was near the surface.

They have tanks that can pump the chemicals or iron oxide into the holding tank.

Can America borrow you guys for a little while?

I know bigger fire fighting planes do, but even little ones like these?! I had no idea they had miniaturized that equipment small enough.
At least this squadron appeared to be dropping pure water....and maybe a few fish.

Two water tanks, each holding 3,655 litres (810USgal) of water, are located roughly at the aircraft's centre of gravity. The tanks are located predominately below the floor in the hull, with each side having a header tank that rises into the fuselage compartment. Forward of each water header tank is a 340.5 litre (681 litre total) foam tank, enough foam for 20 drops. Typically, the foam tanks are filled with a short-term retardant that "gels" the water, allowing it to hang up in the forest canopy and delaying run-off when it reaches the ground. https://www.flightglobal.com/flight-test-bombardier-415-the-superscooper/88562.article

Thanks, was just about to post that link.

I can't imagine much of the equipment has needed miniaturization since WW2.
