Precautions for storage and use of raw material melamine

Precautions for storage and use of raw material melamine

As a chemical raw material, melamine can be used in the production of plastics, coatings, adhesives, and food packaging materials. This article will introduce the precautions for the storage and use of related melamine raw materials.

 

(1) Introduction of melamine

Melamine is a nitrogen-rich heterocyclic triazine, which is mainly used to synthesize melamine-formaldehyde resin for the manufacture of laminates, plastics, coatings, commercial filters, glues or adhesives, and molding compounds (tableware and kitchenware). According to reports, melamine is also used as a colorant (paint coating) and fertilizer.

 

(2) Precautions for the storage and use of melamine raw materials

Note that melamine raw materials can decompose at high temperatures to produce highly toxic cyanide gas.

The product is non-flammable. In case of accidental skin contact, please take off contaminated clothing immediately and rinse with plenty of running water. If you accidentally contact melamine with your eyes, please lift your eyelids immediately, rinse with running water or normal saline, and seek immediate medical attention.

If you accidentally inhale, please leave the scene to a place with fresh air. Seek medical attention.

Ingestion: Drink enough warm water to induce vomiting. Seek medical attention.

Hazardous combustion products: carbon monoxide, carbon dioxide, nitrogen oxides, hydrogen cyanide.

Extinguishing methods: Firefighters must wear filter gas masks (full face masks) or isolation respirators, wear full-body fire-proof and gas-proof clothing, and put out the fire in the upwind direction. Move the container from the fire scene to an open place as much as possible. Operation precautions: airtight operation, full exhaust. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust respirators, chemical safety glasses, protective clothing and rubber gloves. Avoid generating dust. Avoid contact with oxidants and acids. When handling, load and unload with care to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment. Empty containers may be harmful residues.

Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. It should be stored separately from oxidants and acids, and avoid mixed storage. The storage area should be equipped with suitable materials to contain the leakage.

 

(3) Safety problems of melamine

The main problem with melamine is that people may suffer from melamine poisoning due to infiltration into food.

A small study published in 2013 JAMA Trusted Source of Internal Medicine allowed 16 healthy volunteers to consume hot noodle soup in a melamine bowl. The researchers collected urine samples from participants every 2 hours for 12 hours after eating the soup.

The researchers detected melamine in the urine of the participants, which peaked 4 to 6 hours after they ate the soup for the first time. Although the researchers pointed out that the amount of melamine may vary depending on the plate maker, they can still detect melamine in the soup. They did take samples before consuming the soup to ensure that the participants did not have melamine in their urine before starting the study. The authors of the study concluded that the potential for long-term harm from melamine exposure is “still worthy of attention”.

If a person is to consume high levels of melamine, they are at risk for kidney problems, including kidney stones or kidney failure. According to an article in the International Journal of Food Contamination, persistent, low-level exposure of melamine may be associated with an increased risk of kidney stones in children and adults. One of the other concerns about the toxicity of melamine is that doctors do not fully understand the effects of long-term exposure to melamine. Most current research comes from animal research. They do know that some signs of melamine poisoning include:

Blood in urine

Side pain

hypertension

irritability

Almost no urine is produced

Urgent need to urinate

If you have these symptoms, be sure to seek medical attention as soon as possible.
