Pressure Washer Dangers

Yup, they use water to cut steel with Jet Cutting be carefull around that thinkｴg.

But there are times - for instance suppose you have to climb a ladder to spray. My personal rule is one hand for the ladder and the other for whatever tool.
I've found that it's only the initial pull-the-trigger that has the kick. So I hold both the ladder and wand with one hand and pull the trigger with the other.
* Then once it's spraying I try to use a single hand to hold the wand. A bit dangerous, but so is falling off the ladder.

But the water stream can/will still cut you if it hits you.
That's what happened to me.

When I was in the service we used to get shots (immunizations and the like) from a high pressure gun instead of a needle. It was not like the painless "hypospray" as seen on "Star Trek." We were always cautioned to be sure to NOT MOVE or FLINCH when getting the shot as the tiny high pressure stream would slice you like a scalpel.

Same here when I enlisted in The Ohio National Guard & went to Fort Knox KY for basic traning back in 1963.

My understanding of the dangers of injection injuroes is that its not just the direct toxicity of the injected fluid that might lead to limb needing to be amputated Its the "gangrene" [sp?].

Many bad things happen when you get injected by high pressure fluid: 1. There is deep trauma to the tissues - like a bruise, but from the inside. The damage can go deep into joints and bone. 2. The PH and salinity of the fluid is unlikely to match blood, so even with just water, it causes continued slow trauma just being in there. 3. Even if its just water, its not very sterile. 4. There is little or no cleansing action of the wound from from bleeding - just some slow weeping more like a burn. 5. The dead and dying tissue deep inside of you in an environment that just got loaded with non-sterile fluid is a great place to rapidly start growing a massive infection.

If left untreated by surgery and antibiotics, your situation perhaps escalates to a choice between limb amputation or death.
