Static Electric

[fishmusic]

Those black plastic jugs are static dissipating. The makers don't want law suits.

I guess the take away here is that factory plastic powder containers are good to go. :thumbsup:

Thanks for clarifying what I knew about the bottles being antistatic. I thought it was carbon.

 

[necchi]

Anyone interested about anti-static compounds added to PVC containers.
We use Markstat AL-14 and AL-15 (and others)you can search for it but here it is in a nutshell, scroll down to "Summary of Invention" for less Greek; https://www.google.com/patents/US5010139
It's a clear-yellowish liquid delivered in 55gal drums and the stuff is a nasty
(this is rubber gloves but basically only a need for Level C PPE in our process)
We only use it at 3-5%, but we're not making bottles

General reply, not directed at anyone in particular.

Static will not cause black powder to burn, as stated above it is not hot enough to cause it to burn due to the electrical conductive properties of the black powder. The explosions you read about are due to black powder dust in the air. Static will ignite dust. Sawmills have exploded because of sawdust in the air set off by static.

Has I said I can only speak on what I witnessed concerning my friend . But if we look at times past back to the Victorian and Edwardian period how many explosions happened at powder mills and badly ventilated cartridge loading places ,not forgetting badly ventilated firing points where black powder is used was it static electric that was the cause All black powder gives of dust you see that when you fill your container it is a build up of this dust in timber ect and can ignite by static electric

According to Goex's MSDS sheet for Black powder, it is susceptible to static electricity.

Read the hazardous reactivity section. https://www.google.com/url?sa=t&rc...08.pdf&usg=AFQjCNEAmcfCvNmX8J9dWmCX0bzTwyDGKw

I think they would know........

From the MSDS for water... :wink:
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.

Skin:
Wear appropriate gloves to prevent skin exposure.

Clothing:
Wear appropriate protective clothing to prevent skin exposure.

Respirators:
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator

In the Unusual Fire and Explosion Hazards:
It is very sensitive to flame and spark and can also be ignited by friction and impact.

No mention of static (other than metal-free and/or non-static producing clothes), yet they claim BP is susceptible to friction and impact...???

 

[Paul_R]

Friction and impact both generate heat. Heat owns a side of the fire triangle.

As for wood dust being ignited my static, that's true. Because unlike black powder, wood dust is not an electric conductor. It's an insulator and static will generate heat when applied to an insulator.

Ralston Purina dog food factory here blew up per dog food dust few years back. Bad deal.

 

[Bo T]

The ignition temperature decreases as particle size increases. So static electricity might have no effect on ffffg powder, but could be sufficient to trigger an explosion with dust particles that are much smaller. Also, contaminates in the powder might be more susceptible to the static electricity, acting as a detonator.

 

[hanshi]

Down in my native Ga, A sugar cane processing plant suffered an explosion that took lives. Just about any dust from an organic source will explode. I use to blow a pinch of white flour into a capped can with a candle or some other fire source. The top popped off the can very vigorously.

Yah but that's a totally different thing.

The cause of the explosion was the extremely flammable gas that's in that dog food.

Usually, it is trapped inside the food and released only after a dog has eaten it.

I'm sure all dog owners know, after eating the Purina, the dog will quietly walk over next to the chair your sitting in, make three small circles and then lay down.

Shortly after that, he will look up and roll his eyes at you.

Almost immediately you will be surrounded by the stench from Hell and with eyes and nose running you will lunge for the nearest door to safety.

If you have the misfortune of smoking at the time, a blinding, white flash may happen resulting in singed eye brows and eye lashes not to mention the final loss of that little bit of hair that was on top of your head.

Oddly, the dog is not effected by this gas.
He will lay there peacefully sleeping with his nose under his tail. :shocked2:

:rotf:

 

[BrownBear]

My wife nailed me on your post Zonie....

She said "Now you're famous! Purina modeled a dog food after you!" :rotf:

 

[Paul_R]

:rotf: :rotf: :rotf:

I'll add that it's not just Purina.

"Oddly, the dog is not effected by this gas.

Most of the time that's true. Our Setter cut one that was so bad he had to get up and leve the room.

Nope - A legitimate MSDS for water. http://www.labchem.com/tools/msds/msds/75335.pdf
See page 3.


I have another MSDS for water that states:
Section 6 Accidental Release Measures
General Information: Use proper personal protective equipment as indicated in Section 8.

Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in
suitable container. http://www.ch.ntu.edu.tw/~genchem99/msds/exp26/water.pdf

One must employ a little common sense when reading these MSDS sheets as companies are looking to cover their posteriors and go a little overboard with the safety warnings.

I vaguely remember the packaging for a desktop stapler stating the user should wear safety glasses...

 

[coloradoclyde]

I think letting manufacturers write their own MSDS sheets is a mistake...
