What Nasty Stuff do You Work With?

[TURBOs4LIFE]

We make the chemical that goes in pressure treated wood (CCA).

Chemicals that we use in it ...

Arsenic Trioxide

Nitric acid

Chromic Acid

Hydrogen Peroxide (70%)

Potassium Iodine



You always hear on the news about the arsenic being bad in pressure treated wood, but I am here to tell you that the Chromic Acid is alot more hazardous than the arsenic!!



But we also make the non hazardous brand ACQ also

(alkaline copper quartine) This is the new stuff thats is going to replace CCA.

True?

Hey Turbos is it true that they are doing away with the old arsenic treated wood in three months. Got that rumor from a guy at Home depot. I am going to have to hurry and finnish my fence.

dont work with it any more they finnly got rid of it but made by boeing for curosion sp preventaive last thing on the warring was how to give CPR:--) was called bo-shield

By our last report it is supposed to be at the end of the year but only for residential use. You may still buy CCA treated wood for farm use,state use,telephone poles,wood for docks or anything for constant water contact.



The bad things about ACQ is it cost 30% more than CCA treated wood. You cant use anything other than stainless screws or nails.

Also ACQ does not have the 30 year track history as does CCA

(Copper Cromated Arsenic) treated wood.

Thanks

Thanks TURBO , is the CCA wood really as hazardous as they say? Or can you get away with not wearing dust mask and gloves and not have green cohones in two weeks? Its over 100' here daily and a mask and gloves are hard to live with.

If you work with CCA treated wood regularly,Yes it is highly recommended that you use at least a dust mask. You also dont have to look at CCA treated wood like its evil because its relatively safe it just that I dont recommend using it for toothpicks

 

[illflem]

CCA treated posts were banned in WA state for agricultural use a couple of years ago because of arsenic residues in the soil and crops. Growers have switched over to steel and copper treated wood for uses such as trellis posts. CCA is still ok for fence posts.

Thanks

Thanks again TURBO. I will just continue on useing the dust mask and gloves for the major cutting sessions.

Mostly H2S for the last 12 years.



First job out of school was for a large oilfield service company (who will remain nameless) rebuilding MWD (Measurement While Drilling) tools. These items measured direction, formation resistivity and gamma ray emission. To test the gamma ray detector, we used a Cesium source. Not quite as bad as all of the Carbon Tetrachloride I used to clean parts with, or the Beryllium Copper stabilizer subs that I would machine on the lathe. We also had an EMR tool (elect. magnetic resonance), but I didn't mess with that.

One day the head cheeze of Development came through and said we will be using a new tool. This one measured Neutron porosity of the formation. I asked "what source will we use to test it?" He replied, "Americium 241" (I think, I'm not real good with neuclear chemistry). Anyway, I inquired as to how we are to handle the source. I was told that we would use a 14' pole, and the neutrons would collide out in that distance of atmosphere. All I remember from one of my neuclear safety classes is that Neutrons "might" collide out in 3' of CONCRETE. I quit shortly thereafter.

Plutonium, Americium, Cesium, & Thorium to name a few favorites... .

 

[JR2]

me4osu- Heck I run those tools (for one of the big companies), they are not bad if you follow all the procedures involved and wear your monitoring badge. The sources never leave the shielding and all is well. I would be more worried about the dust from the BeCu subs. We don't use that stuff any more. It will kill ya...

 

[me4osu]

Yeah, we used to flood the cutting tool with coolant and take shallow passes. All I really did was true up the API sealing face, when our thread inspector failed them. Also, we made sure not to breathe the dust, although we obviously should have been wearing respirators.



Oh well, the things we learn. The gals at the Radium Dial factory used to sharpen their radium paint-brushes by sticking them in their mouths. There's a "lesson learned".

 

[Morphious]

Lets see, right out of high school, I worked for a perforating company where we blew holes in the oil wells. The primer cord burned a mile a second... .



On one BSing occasion at somebodies shop, they didn't believe the explosive power of the primer cord, so he took an inch long piece and whacked it with a 5lb sledge hammer. Blew the sledgehammer out of his hand and through the roof 15' up.



Another time, we were on a well site and some moron had used regular cement to cement the head in (instead of the porous well cement), the pulling unit crew was out there with pickaxes, shovels and rock bars trying to break it away. We finally got tired of watching the spectacle and offered our assistance. We took a 3 foot piece of primer cord with a cap on the end and burrowed a hole down alongside of the cement, placed some large rocks on top of it and got back pretty far before we ignited it. BOOOOOOM... . after the dust settled, we inspected it and found that we had only cleaned out dirt around the hole and made a pocket around the pipe below the well head. Sooooo, we took 10' of the primer cord this time, packed even more dirt and rocks on top of the charge and got way in the hell back this time and BOOOOOOOOOOOOM... . this time, we blew head sized chuncks of cement 90' up in the air past the top of the derrick, but we did get the job done.



On that job we also used cessium nuclear sources to log the formations in the ground.



Other things I have worked with are Blue, Red and Ultra Violet lasers, electroforming acid baths, 2500 ton presses, assembly lines with robitic welders, shooting mail 180 inches per second down conveyer belts, Chicken Remote Access Programs (CRAP) for controlling environments... .



Oh yeah... forgot the current job, now I am working with goverment buerocrats ... .



Morph.

In 1971 I got out of the Army and went for work for a company which sprayed noxious mixtures on the outside of stone buildings in Wash. D. C. , and then hosed it all off with high pressure washers. We worked on scafolding, descending from roof top.



One day I walked though the warehouse with the boss, and I pointed out a 50 gal. drum which was leaking. Boss said, "Oh don't worry about that stuff, it won't hurt ya. " I don't know what it was... but about 15 min. after I walked through it, the soles of my work boots both fell off and also the skin of my feet peeled off.

check out this list of nasties I have to watch out for.



Tungsten Hexafluoride (WF6)

Silane (SiH4)

Nitrogen Trifluoride (NF3)

Aqueous HF (Hydrofluoric Acid)

Germanium

Arsenic

Phosphine (PH3)

Arsine (AsH3)

Hydrogen Bromide (HBr)

Hydrochloric Acid (HCl)



and some real nasty mixtures of crap that pH out at close to 0.



I really hate being in full acid gear and forced air ventilation (SCBA), but it saves my butt!

Our MSDS book lists some 1400 chemicals and compounds. I can respect and deal with the ones I have to. It's the politics and the slump the electronics industry are in that scare me.

How about Bio-Hazards in a moving vechile?

Our book is pretty big too. We go through a lot of haz-mat training.

The thing that scares me the most:

We were doing a meeting on HAZ-WOPER (I forget what it's short for) in the meeting it was disgussed that "if the pentane tank was ever attacked, the hole would be 1/4 mile round".

I work about 100 feet from this tank. :--)
