Introduction
Pyrotechnic fireworks displays are hazardous to people's health and release a lot of poisonous metals into the atmosphere. The pyrotechnics industry uses the strontium nitrate detailed in this article. Nitrogen and strontium combine to form strontium nitrate. Understanding the potential human health impacts of strontium is crucial. The days before July 4th and New Year's Day had 19 of the 22 largest peaks (i.e., higher than 0.15 g/m3) of strontium (Sr) in airborne particles in the U.S. Due to the rarity of strontium compared to other polluting sources and the widespread use of red hues in fireworks, strontium can serve as an effective environmental indicator of fireworks activity.
Furthermore, it is also hazardous since combustibles, including wood, paper, and oil, may catch fire when exposed to strontium nitrate. Strontium Nitrate may explode if exposed to heat, stress, or friction over an extended period. Nitrates may impact the oxygen delivery in our blood. The oxygen-carrying protein in the blood, hemoglobin, can change into methemoglobin when exposed to nitrate. High concentrations can cause the skin to become blue or gray, and more significant health consequences include weariness, weakness, and dizziness. Read on to learn more.
What Is Strontium Nitrate?
This article discusses the strontium nitrate formula, commonly known as the strontium dinitrate formula or the strontium nitrate formula. It is an inorganic compound comprising two elements, strontium and nitrogen. Strontium nitrate's chemical name is strontium nitrate, or Sr(NO3)2. The substance strontium dinitrate is a white, crystalline solid. Although it is a fireproof substance, it improves the burning of substances that are. If an excessive amount of nitrate de strontium is involved in the fire, it may explode. Additionally, it may explode if heated for an extended time. It releases poisonous nitrogen oxides when burned.
What Is Strontium Nitrate Used For?
Applications of strontium nitrate are:
-
Manufacturing of pyrotechnics as it imparts brilliant color to a flame (red fire).
-
Signal lights.
-
Marine signals.
-
Railroad flares.
-
Matches.
-
Military tracer bullets.
-
In electron tubes.
-
As a pigment.
-
In matchsticks, railroad flares, marine signals, signal lights, and pyrotechnics (red fire).
-
Used as an oxidizer and colorant in fireworks.
What Is Strontium Nitrate Toxicity?
1. Methemoglobinemia:
A nitrate of strontium is strontium nitrate. In fireworks, it serves as an oxidizer and colorant. Once nitrate enters the body, it is converted to nitrite, which causes nitrate poisoning. Methemoglobinemia is a hazardous condition caused by nitrite ingestion. Nitrites may have negative effects on development and complicate pregnancies.
Moreover, they could potentially cause cancer. If nitrate is consumed, oxyhemoglobin is autocatalytically oxidized to hydrogen peroxide and methemoglobin. As methemoglobin cannot bind oxygen, the condition when methemoglobin levels are elevated is known as methemoglobinemia and is characterized by tissue hypoxia.
Cyanosis, cardiac dysrhythmias, circulatory failure, and developing Central Nervous System (CNS) consequences are among the symptoms. CNS side effects might vary from slight drowsiness and lethargy to convulsions and coma.
2. Other Acute Health Effects of Exposure:
It is a severe skin irritant, a moderate mucous membrane irritant, and an eye and respiratory tract irritant. Due to its potent oxidizing properties, it poses a fire risk when in contact with organic materials. Shock or heat may also produce an explosion, causing burn injuries.
3. Other Risk Factors
Alcohol consumption might worsen liver damage from strontium nitrate. Strontium nitrate intake may raise the chance of developing bone deformities in those whose diets are deficient in calcium.
How Is Strontium Nitrate Toxicity Diagnosed?
Any evaluation should include a careful history of past and present symptoms with a clinical examination. The following diagnostic methods are advised if symptoms appear if overexposure is thought to have occurred:
-
Lung function tests.
-
Nervous system examinations.
-
Kidney function tests.
-
Electrocardiogram (EKG).
-
Bone Density Scan.
How Can Strontium Nitrate Toxicity Be Managed?
Acute Health Effects Management:
Primary Treatment: Seek medical assistance. If there has been eye contact, rinse with water. If skin contact occurs, immediately rinse with water. While being transported, continually irrigate both eyes with normal saline. If consumed, sip on water, milk, or activated charcoal before making oneself throw up. Please take note that one should not attempt to feed water or milk someone unconscious. Create a clear airway. Monitor for indications of respiratory insufficiency and help with ventilation if required.
Advanced Treatment: If a patient is unconscious or experiencing respiratory arrest, orotracheal or nasotracheal intubation may be used to manage the airway. Keep an eye on the heartbeat and, if required, treat arrhythmias. If there are hypovolemic symptoms, use lactated Ringer's. Fluid should be administered with caution in cases of hypotension and hypovolemia. Vasopressors may be useful if the patient does not respond to these treatments. Keep an eye out for indicators of fluid excess. Use Diazepam to treat seizures. If the patient exhibits symptoms of severe hypoxia, cyanosis, and cardiac compromise that are not responding to oxygen, provide a 1% solution of methylene blue. Proparacaine hydrochloride can be used to help in ocular irrigation.
Methemoglobinemia Management:
Supplemental oxygen and methylene blue 1% solution given intravenously slowly over five minutes, followed by an IV flush with normal saline, are effective treatments for methemoglobinemia. Iron in hemoglobin is returned to its natural (reduced) oxygen-carrying condition by methylene blue.
What Are the Ways to Prevent Strontium Nitrate Toxicity?
1. Personal Protective Equipment: Avoid getting strontium nitrate on the skin. Wear personal protection equipment made of a material resistant to this substance's permeability or degradation. Safety equipment suppliers and manufacturers might suggest the industry's best glove and apparel materials.
2. Spills: If Strontium nitrate is spilled, take the following steps:
-
Secure and control the entry of the area while evacuating the personnel.
-
Remove all potential ignition sources.
-
The most practical and secure way to gather powdered material is to deposit it into sealed containers for disposal.
-
After cleanup is done, ventilate and disinfect the area.
-
Do not wash down the drain. Currently, the criteria for land treatment or burial (sanitary landfill) disposal procedures are significantly under review. Consult with environmental regulatory organizations for advice on proper disposal procedures before implementing land disposal of waste residue (including waste sludge).
3. Storage: Protect from friction and shock and store in firmly closed containers in a cool, well-ventilated environment apart from moisture.
Conclusion
The fundamental principle of worker protection is limiting exposure to hazardous and chemical risks. The workable and efficient controls and environment are decided using a hierarchy of controls. And to avoid problems, it is best to seek medical attention once symptoms appear.
