Yes sodium azide is dangerous for human health. Symptoms and indicators of sodium azide poisoning are given below:

Symptoms and indicators of sodium azide poisoning

People who are exposed to a little quantity of sodium azide by inhaling, skin absorption, or consuming food containing it may experience any or all of the symptoms listed within minutes:

People who are exposed to a little quantity of sodium azide by inhaling, skin absorption, or consuming food containing it may experience any or all of the symptoms listed within minutes:

  • Nose discharge should be clear
  • Coughing (gas or dust exposure)
  • Dizziness
  • Migraine
  • Vomiting and nausea
  • Breathing fastly
  • A heart rate that is quite fast
  • Eyes that are bright red (gas or dust exposure)
  • Anxiousness
  • Weakness
  • Burns and blisters on the skin 

Other health problems may occur as a result of exposure to a substantial quantity of sodium azide through any route:

  • Convulsions
  • Blood pressure that is too low
  • Awareness loss
  • Injury to the lungs
  • Respiratory failure that results in death
  • Heart rate is low.

It is not always the case that a person has been subjected to sodium azide by displaying these signs and symptoms.

What should individuals do if they are subjected to sodium azide and how can they protect themselves?

You can protect yourself by following the guidance given below:

  • To begin, leave the place where the sodium azide was emitted and seek some fresh air. Moving to a location with fresh air may help to lower the risk of mortality from sodium azide exposure.
  • If the sodium azide leak occurred outdoors, walk away from the source of the sodium azide.
  • Get out of the area if the sodium azide was released inside.
  • If you can’t get out of the location where you were subjected to sodium azide, keep as low to the ground as possible since sodium azide fumes ascend.
  • If you are near a sodium azide leak, emergency responders may advise you to flee the area or “take shelter” inside a facility to prevent exposure to the toxin. 
  • If you believe you have been subjected to sodium azide, you should immediately remove your clothes, wash your whole body with water and soap, and seek medical attention.

Taking off your clothes:

  • Remove any clothes that may have sodium azide on it as soon as possible. Any garment that has to be dragged over the head must be cut off the body rather than dragged over.
  • If you’re assisting others in removing their clothes, keep your hands away from any contaminated places and remove the garments as fast as possible.

Washing yourself:

  • Wash any sodium azide from your skin as soon as possible with a lot of soap and water. People may protect themselves against toxins on their bodies by washing with water and soap.
  • If your eyes are burning or your sight is blurry, rinse them for 10 to 15 minutes with plain water. Take your contacts and place them with the infected garments. Do not re-insert your contacts into your eyes. Wash your glasses with soap and water if you wear them. After you’ve cleaned your glasses, you may put them back on.

Getting rid of your clothes:

  • Place your clothes inside a plastic bag once you’ve washed them. Touching contaminated portions of clothes should be avoided. Wear rubber gloves or place the garments in the bag with forceps, tool handles, sticks, or similar things if you can’t avoid handling contaminated parts or aren’t sure where they are. Anything that comes into contact with the contaminated clothes should be put in the bag as well. Put your contacts in the plastic bag as well if you wear them.
  • Seal the bag, then place it inside a second plastic bag. This kind of garment disposal can help safeguard you and others from any contaminants that may be present in your clothing.
  • Tell the state or local health agency or emergency officials what you did with your garments when they come. Further disposal will be arranged by the health dept or emergency responders. Do not attempt to carry the plastic bags on your own.
  • Do not induce vomiting or provide fluids to someone who has consumed sodium azide. If you’re certain the victim has consumed sodium azide, don’t try CPR with mouth-to-mouth breathing. If you do CPR on someone who has consumed sodium azide, you may be exposed to the poison.
  • When sodium azide is consumed, it reacts with stomach acid to produce hydrozoic acid, a deadly gas. To prevent exposure to the poisonous gas, separate the individual who has consumed sodium azide and remain away from the gastric contents (vomit).
  • Food, drink, or vomit containing sodium azide should not be poured down the drain, since the drain may burst and cause severe injury.
  • Seek medical help as soon as possible.

Characteristics od Sodium Azide

COLOR: A hexagonal crystalline solid that is colorless to white in appearance.

Description: Sodium azide is a colorless substance with no odor. When it comes into contact with water or an acid, it quickly transforms into a poisonous gas with a strong stench and releases hydrazoic acid (HN3). The gas’s stench may not be enough to tell you that you’ve been exposed to it. Regular car mechanics are more likely to be exposed to sodium azide, which is used as an airbag propellant. Sodium azide is also used to make a variety of chemicals, as a preservative and a microorganism fumigant in agriculture, in clinical and research labs, in sponge rubber, in detonators, and as an intermediary in the production of explosives. Sodium azide poisoning is very dangerous.

Response to a Crisis

Here’s how sodium azide respond to a crisis:

Chemical Danger:

  • Acids with various metals cause explosive reactions and/or the formation of explosive and/or shock-sensitive compounds.
  • With hot water, it reacts quickly.
  • Aluminum and copper are corroded.
  • When metals come into contact, hydrogen azide may form, which is combustible.
  • The fumes of hydrazoic acid are hazardous when they come into contact with acid.
  • Acid causes poisonous hydrazoic acid vapors to form when it comes into contact with it.

Hazards of explosion:

  • When heated over its melting point, sodium azide may explode, particularly if heated quickly.
  • Shock, concussion, or friction may cause it to dissolve explosively.
  • Bromine, carbon disulfide, and chromyl chloride all have explosive reactions with it.
  • When phosgene, brass, zinc, trifluoroacrylol fluoride, and nitrogen-diluted bromine vapor are combined, explosive chemicals are formed.
  • Shock-sensitive compounds are formed by combining copper, lead, silver, mercury, and carbon disulfide.
  • When combined with acids, hydrazoic acid is formed.
  • When heated, vapors may combine with air to generate explosive combinations, posing an explosion risk both inside and out, as well as in sewers.
  • Heat may cause containers to burst.

Information on fire prevention:

  • Combustible sodium azide
  • Although the agent may burn, it is difficult to ignite.
  • Inflammable, caustic, and/or hazardous gases may be produced by fire.
  • It is possible to carry the agent in a molten state.
  • Dry chemical, co2, or water spray may all be used to put out minor flames.
  • Dry chemical, co2, alcohol-resistant froth, or water may all be used to put out huge flames. If it is feasible to do so without endangering employees, move containers away from the fire. Don’t distribute the debris; dike fire control water for later disposal.
  • Use autonomous hose holders or monitoring nozzles to combat fires involving containers or car/trailer loads. Water should never be allowed to enter containers. Cool containers by filling them with water once the fire has been extinguished. If you hear a loud noise coming from the venting safety devices or see discoloration in the tanks, you should get out of there very once. Keep a safe distance from burning tanks.
  • Dilution or run-off from firefighting. Water has the potential to be caustic, poisonous, and polluting.
  • Control and dispose of run-off as needed if the circumstances permits (effluent).

Symptoms

Time course: Following sodium azide exposure, clinical symptoms might be virtually immediate or delayed, and they can take days or months to entirely resolve in certain situations.

Short term exposure has following impacts:

Sodium azide is a metabolic poison (toxin) with a wide range of effects that impairs the body’s capacity to utilise oxygen to sustain life. Low blood pressure (hypotension) is the most generally reported health consequence, and it may happen via any route of exposure: ingesting, skin contact, or inhaling. Headaches, short-term unconsciousness (syncope), loss of muscular tone and strength, long-term unconsciousness (coma), and seizures are all possible side effects of ingesting and inhaling exposure. 

Laboratory results show an increased white blood cell count after mild to moderate exposure. As a result of the body’s inability to utilise oxygen, there is a build-up of acids in the circulating blood (lactic acidosis). Sodium azide intoxication may be lethal in the most severe circumstances.

Eye exposure

Conjunctivitis is characterized by inflammation and damage of the membranes, impaired vision, and pupil dilation (mydriasis).

Exposure to ingestion

  • Mild to moderate: headache, overall sensation of unease and being sick, syncope (brief loss of consciousness), uneasiness, vomiting (emesis), diarrhea, stomach discomfort, and extreme thirst (polydipsia).
  • Severe: Serious low blood pressure (hypotension), which may be predated by hypertension, lowered state of consciousness (Central nervous system depression), convulsions, coma, pain in the chest, slow or fast heart rate, unusual or disturbed heart rhythms (atria and ventricles dysrhythmias), breathing difficulties or shortness of breath (dyspnea), buildup of fluid in the lungs (pulmonary e Convulsions, coma, and death are all possible outcomes.

Exposure to inhalation

  • Exposure via ingestion or inhalation may both have negative health consequences.
  • Inhalation exposure may result in less severe gastrointestinal symptoms (stomach pain, vomiting, and diarrhea).
  • In addition, vapors of sodium azide (hydrazoic acid) might induce the following symptoms:
  • Irritation of the eyes and respiratory mucous membranes (nose and throat), probable airway inflammation (bronchitis), and fluid build-up in the lungs (pulmonary edema).

Exposure to the skin

  • Irritation and inflammation are the two most common side effects on the local level. There’s a chance you’ll break out in a rash.
  • Low blood pressure has a whole-body (systemic) impact (hypotension).

Frequently Asked Questions(FAQs), “Is sodium azide flammable”

Is sodium azide hazardous?

Inhaling the gas generated by sodium azide is the most dangerous, although eating (swallowing) sodium azide may also be harmful. The gas produced by sodium azide is particularly hazardous in confined spaces where it will be retained. The hazardous gas disperses fast in open areas, making it less dangerous outside.

Is sodium azide an explosive?

When sodium azide is coupled with moisture or acid, it quickly hydrolyzes to generate hydrazoic acid, a very dangerous and destructive gas. Sodium azide gets statically charged and quickly evaporates in fume hood airflow.

Is sodium azide heat sensitive?

These compounds, like several organic azides, are famously heat and stress sensitive, and may dissolve rapidly with little external power input. Sodium azide forms strongly degradable chemicals when it combines with carbon disulfide and dimethyl sulfate.

What makes Azidoazide azide explode?

1-Diazidocarbamoyl-5-azidotetrazole, often known as “azidoazide azide,” is a 14-nucleotide heterocyclic chemical molecule. The compound is very explosive due to the enormous amount of high energy nitrogen bonds.

How do you clean up a sodium azide spill?

Metal equipment should not be used to clean up a little spill of sodium azide. Chemical absorbent pads may be used to clean up spills. Using sand, cover the solids, scoop them up, and put them in a non-metal container. Wipe the area off with a soap and water solution at least twice once the spill has been entirely absorbed.

What happens if you inhale sodium azide?

Furthermore, contact to sodium azide fumes (hydrazoic acid) may cause eye irritation and mucous membranes of the respiratory system (nose and throat), as well as probable airway inflammation (bronchitis) and fluid buildup in the airways (pulmonary edema).
