Finding Proper Shipping / Technical Name 2

[mgau]

Dear All,

I have came a cross a chemical some kind of liquid solvent (Which appeared to be voliatile and on explosive nature) which contains the following properties, which was described as "POLISH WAX".

No. 1

Silicone Fluid 30%
Xylene 70%

No. 2

Silicone Fluid 15%
Phospheric acid 10%
Surfactant 20%
Water 55%

Please help me to identify the

1. Proper Shipping or correct technical name.
2. The nature of each product.
3. Whether they are catergeised under Dangerouse Goods Cargo under the IMDG, if so belongs to which class ?


Thank you

SM

Get the MSDS that should tell you. If you don't have it contact the manufacturer.

I don't see how it is explosive. But with 70 percent xylene it could be flammable. A Class 3 flammable liquid has a flash point less than 60.5 degrees C. A Class 3 combustible liquid has a flash point between 60.5 C and 93 C.

The one with phosphoric acid could be corrosive which is Class 8.

OK so why are you shipping it? If you are disposing it. You are now shipping a hazardous waste. Use a hazardous waste manifest with the proper identification. The licensed transporter will complete the form. You have to sign it.

Dear Vintage70,

Thank you for your post. The information is well received. Let me give you a bit more information concerning the content. The LEL (Low Explosive Level) was found over 135, I undertand that once LEL is over 56, the exposed area of this liquid could be hazadouse.

One more question regarding the contents, Should this liquid able to create an explosive envirment within its container under the normal pressure / temperature, however if the flash point is 65 centigrade, this seems impossible. Am I correct ?

thanks

You need to contact a local Industrial Safety Consultant or Industrial Hygienist. Your evidence is very convoluted. Please re-read the information from Vintage70. The LEL can not be over 99.99999+ by definition as the LEL and UEL are percentages of the vapor in a air mixture. A measurement of 1/5 of the LEL is by OSHA standards a point of control, but this is not a shipping issue.

If you meant the FP/flash point is 135 C, then it is above the definition of combustible and is not a shipping issue. Also, FP has nothing to do whatsoever with explosive potential.

phoward answered the question. There are 6 divisions of Class 1 explosives. If you read them, it does not appear that this particle product, understand it's called Polish Wax,is an explosive. You didn't answer my question as to why are you shipping it.

Dear Vintage70,

I am not shipping this substance, it had shipped by another party and we had a problem (Explosion and fire) with it. However there was a another substance nearby stowage alled PU RESIN., this also appeared quit voliatile, but may be less voliatile than that of Polish Wax. I want to deffernciate this two substances, which one is more explosive.

Many thanks for your reply.

You had an explosion and a fire because of these chemicals?
Generally explosive materials create a blast or a projectile. They include explosive and detonating devices.
It appears you have flammable liquids. I don't see how they can be explosive, by shipping definition, especially at ambient pressure. If the pressure of the containers are greater than atmospheric due to volatility or elevated temperatures, you have a dangerous condition. They may not be stored properly. There must be some instructions or special requirements for the storage of these compounds.

mgau, It sounds as if what you had may have been a "BLEVE" ( boiling liquid expanding vapor explosion). What happens when volatile (high vapor pressure substances), especially flammable substances get hot (high atm. temp. in some cases can cause this) the fluid expands in the container above the allowable pressure, the container ruptures throwing out a flammable vapor plume that is then set off, a deflagration, that appears to be an explosion and fire.

In terms of safety, this requires proper storage procedures in proper containers, in proper Class/Division areas, paying particuliar attention to storage temperatures and potential energy sources that can light of the vapors.

Another question to ask, is did your personnel accidently mix incapatible materials that resulted in an exothermic reaction that caused the deflagration?

Hope this provides some insight.
