In practical applications, glyoxal will cause toxicity and cause harm to the human body due to heating or burning. Therefore, the precautions for the use of glyoxal are particularly important.

Therefore, Zhonglan Industry has compiled precautions regarding the use of glyoxal, including risk review, first aid methods, fire protection methods, leak emergency treatment, use and storage, and so on.

Detailed description below

Risk overview

Health hazards: Harmful if inhaled, ingested or absorbed through the skin. It has a stimulating effect on the skin and can cause dermatitis; steam or mist has a stimulating effect on the eyes, mucous membranes and upper respiratory tract.
Environmental hazard: It is harmful to the environment and can cause pollution to the atmosphere.
Explosion hazard: This product is toxic and irritating.


Skin contact: Remove contaminated clothing and rinse with plenty of running water.
Eye contact: Lift eyelids and rinse with running water or saline. Seek medical attention.
Inhalation: Remove from the site to fresh air. If breathing is difficult, give oxygen. Seek medical attention.
Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.

Fire-fighting measures

Hazardous properties: Strongly reducing. In case of high heat, open flame, oxidant, fuming sulfuric acid, chlorosulfonic acid can cause combustion and explosion. Contact with water can cause intense polymerization, and self-polymerization can occur during storage and use.
Hazardous combustion products: carbon monoxide, carbon dioxide.
Fire-fighting methods: Firefighters must wear gas masks, wear full-body fire-fighting suits, and put them on the wind. Move the container from the fire to the open space as much as possible. Spray water to keep the fire container cool until the end of the fire. If the container in the fire has changed color or produces sound from a safety relief device, it must be evacuated immediately.
Extinguishing media: water spray, foam, dry powder, carbon dioxide, sand.

Leakage emergency treatment

Emergency treatment: Quickly evacuate personnel from the contaminated area to a safe area, and conduct isolation to strictly restrict access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and wear anti-virus suits. Cut off the source of the leak as much as possible. If it is liquid, it will prevent it from flowing into restrictive spaces such as sewers and flood drains.
Small spill: Mix with sand, dry lime or soda ash. It can also be rinsed with a large amount of water, diluted in water and placed in the wastewater system.
A large number of leaks: building a dike or digging a pit. Cover with foam to reduce steam hazards. Transfer to a tank truck or special collector with a pump, recycle or transport to a waste disposal site for disposal. If it is solid, mix it with sand, dry lime or soda ash. If there is a large amount of leakage, collect it for recycling or transport it to a waste disposal site for disposal.

Handling and storage

Handling precautions: Closed operation, pay attention to ventilation. Operators must be specially trained to strictly follow the operating procedures. Operators are advised to wear self-priming filter dust masks, chemical safety glasses, anti-poisoning overalls, and rubber gloves. Keep away from fire, heat, and smoking in the workplace. Use explosion-proof ventilation systems and equipment. Prevent smoke or dust from leaking into the workplace air. Avoid contact with oxidants and alkalis. Lightly load and unload during handling to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.

Storage Precautions: The product is usually stored after dilution. Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature of the reservoir should not exceed 30 °C. The package is sealed and must not be in contact with air. It should be stored separately from oxidants, alkalis and food chemicals, and should not be mixed. Explosion-proof lighting and ventilation facilities are used. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
