Part II Composition/composition information
LABSA is an organic weak acid that dissolves in water and is diluted with water to give off heat. Dodecylbenzenesulfonic acid is a brown viscous liquid.
Density: 1.2
Melting point: 10°C
Boiling point: 315°C

Part III Risk Overview
If swallowed, it can cause serious burns.
Potential health effects:
Eyes: Causes eye burns.
Skin: Causes skin burns that can be absorbed through the skin.
Ingestion: Harmful if swallowed. Causes Digestive tract burns.
Inhalation: If inhaled may burn respiratory tract.

Part IV First Aid Measures
Eyes: Remove and isolate contaminated clothing and shoes. Wash skin with soap and water. Keep your patient warm and keep quiet. Ensure that medical personnel understand the relevant personal protective knowledge of the substance and pay attention to its own protection.
Skin: Immediately seek medical assistance and rinse skin and clothing attachments, remove with plenty of water for at least 15 minutes.
Ingestion: Do not induce vomiting. Seek medical assistance immediately.
Inhalation: seek medical assistance immediately. Remove skin and clothing attachments and immediately transfer to a ventilated place. If breathing is difficult, give oxygen.
Part V Fire Fighting Measures
Extinguishing media: Use foam, dry powder or carbon dioxide.

Part VI Emergency Response to Leakage
General Information: Use appropriate personal protective equipment.
Spill/leakage: Use inert material to absorb liquids (such as vermiculite, sand, or earth) that overflow the container and do not allow the chemical to spread.
Small Spills: Dilute with water and mop, or absorb containers with inert dry matter and place in a suitable waste disposal.
Large spill: corrosive liquids. If there is no risk of stopping the leak. Absorption and arid earth, sand or other non-combustible materials. Do not let water in the container. Do not touch spilled material. Use water spray curtains to shift steam drift. Prevent entry into sewers, basements or narrow places; if needed. Eliminate all sources of ignition. Seek help.

Part 7 Operation and Storage
Treatment: Do not breathe dust, vapors, mist or gas. Do not touch the eyes, skin or clothing directly. Do not ingest or inhale.
Storage: Store in a cool, dry place.

Part 8. Exposure Control/Personal Protection
Monitoring method:
Engineering Controls: Provide exhaust ventilation or other engineering controls to keep the air concentration below the respective steam threshold limits. Make sure that nonsense and safety showers are also near the station's work-station location.
Personal protection: masks. All clothes. Protective mask for steam. Make sure to use an approved/certified mask or equivalent. gloves. boots.
Personal protection against large spills: Splash goggles. All clothes. Protective mask for steam. boots. gloves. A self-contained breathing apparatus should be used to avoid inhalation of the product. Proposed protective clothing may not be sufficient; consultants are working on this product. Eye wash facilities and shower facilities should be provided. Use proper air circulation to maintain a low concentration in the air.
Personal Protective Equipment
Eyes: Wear chemical splash goggles.
Skin: Wear suitable protective gloves to prevent skin contact.
Clothing: Wear appropriate protective clothing to prevent skin contact.

Part XIV Transport Information
Dangerous goods number: No data
UN number: UN2584 PG: II
Packaging logo:
Packing category:
Packing method: No data available.
Hazardous: Corrosive liquids
Health: 3
Flammability: 1
Reactivity: 0
Transportation Note: LABSA should check whether the packaging container is complete and sealed before transport. Ensure that the container does not leak, fall, fall, or damage during transportation. It is strictly prohibited to mix and transport with oxidants, acids, and food chemicals. Transport vehicles must be thoroughly cleaned and disinfected, otherwise no other items may be shipped. When shipping, the fitting position should be far away from the bedroom, kitchen, and isolated from the engine room, power supply, fire source and other parts. When driving on roads, follow the prescribed route.
Firefighting: The number of water drives used is in the fog. A solid river may also be ineffective. Cold and flooding affect the amount of water in the container. Using water far away is feasible. Drinking foam, dry powder extinguisher and carbon dioxide. Use water spray to knock down steam.
Part XV Regulatory Information
Regulatory Information: Regulations on the Safety Management of Chemical Hazardous Substances (promulgated by the State Council on February 17, 1987), Regulations for the Implementation of Safety Regulations for Chemical Hazardous Substances (Chemical Work [1992] No. 677), and Regulations on the Safe Use of Chemicals in the Workplace ([1996] Law of the Ministry of Labor issued No. 423 and other laws and regulations have made corresponding provisions for the safe use, production, storage, transportation, loading and unloading of chemical dangerous goods.
