How do you dispose of sodium azide?
Destruction. Solutions of 5% or less of sodium azide can be destroyed by reaction with freshly prepared nitrous acid. Destruction MUST be conducted in a working fume hood and in an open container due to the release of toxic nitric oxide (NO) gas.
Can sodium azide go down the drain?
Sodium azide should never be flushed down the drain since this practice can cause serious incidents when the azide reacts with lead or copper in the drain lines and explodes. Moreover, sodium azide has high acute toxicity as well as high toxicity to bacteria in water treatment plants.
Is sodium azide acutely hazardous waste?
Click here to enter a date. Sodium Azide (NaN3) is acutely toxic, water reactive, and a potentially explosive chemical.
How do you dispose of sodium?
Waste Disposal: All waste sodium must be disposed of as hazardous waste. Scraps must be in a bottle under mineral oil, properly labeled, and given it to EH&S for disposal. Scraps of sodium can be destroyed in the lab shortly after generating them to reduce the hazards of storing sodium as hazardous waste.
Does sodium azide react with water?
When it is mixed with water or an acid, sodium azide changes rapidly to a toxic gas with a pungent (sharp) odor. It also changes into a toxic gas (hydrazoic acid) when it comes in contact with solid metals (for example, when it is poured into a drain pipe containing lead or copper).
How do you quench sodium azide?
Cool down the reaction mixture to 0 deg C and slowly add water to quench the excess sodium azide. just adding water will not destroy the sodium azide, my reaction is in water. If you extract your product first, you can quench the aqueous phase with sodium nitrite and acid without losing your product.
What chemicals can be poured down the drain?
The only substances allowed down drains are those that meet all of the following criteria:
- Nonhazardous. No radioactive waste. No hazardous chemical waste.
- Liquid. No solids, sludges, or viscous substances.
- Will not interfere with sewage treatment operations. No corrosive pH levels. No grease or oil.
How do you quench azide waste?
- In a three-neck flask with a stirrer, dilute the azide with water so that it does not exceed 5%
- With stirring add a 20% solution of sodium nitrite containing 1.5 g of sodium nitrite per gram of azide.
How do you handle azides?
Azides should be stored plastic amber containers, and away from light. 6.1 Organic azides should be converted to a stable derivative (such as an amine) prior to being disposed as chemical waste. 6.2 All azide-containing materials should be disposed via the University’s chemical waste program.
What chemicals should not go down the sink?
Chemicals That Should NOT Go Down the Drain
- Ether (both ethyl and methyl ethers)
- Halogenated hydrocarbons.
- Nitro compounds.
- Flammables (immiscible in water)
- Explosives such as azides and peroxides.

What is the most explosive element on earth?
Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state.
What happens if you touch sodium azide?
Following release of sodium azide into the air, you could be exposed by breathing in the dust or the gas that is formed. Sodium azide can also enter the body and cause symptoms through skin contact. An explosion involving sodium azide may cause burn injury as well as expose people to the toxic gas, hydrozoic acid.
Can sodium carbonate go down the drain?
Soda ash may be able to be washed down the drain but be aware that it’s quite alkaline and could create pH problems if you have a septic system. It probably won’t do any harm to wash a small amount of soda ash solution down the drain followed by a lot of water.
Can you put poop down the sink?
Things You Should Never Flush This is quite simple, actually. The only three things that really should ever be flushed down the toilet is urine, fecal matter, and toilet paper. It definitely isn’t rocket science, but yet people flush plenty of other things that they think they can get away with all the time!
Is it OK to pour vinegar down the drain?
Vinegar is both safe and beneficial to pour down your drain. It acts as a natural cleaning solution and can remove blockages and harmful bacteria that cause foul odors.
If using the sewer system for disposal, flush sodium azide with 100 times more water than the solution itself Label all containers, waste disposal fixtures, and any medical instruments which use products containing the compound Don’t store tubing or any other materials that could have come into contact with sodium azide solutions
What is involved in deactivating sodium azide?
All personnel involved in deactivating sodium azide shall conduct inspections, maintenance, or other activities to ensure that the process does not result in spills, leaks, or emissions into the environment prior to deactivation of the material.
What are the safety precautions for sodium azide?
HANDLING AND STORAGE. Prior to working with sodium azide you should be trained on its proper handling and storage. Use appropriate personal protective equipment such as safety glasses, goggles, gloves, and laboratory coat when handling sodium azide.
