Styrene-acrylic emulsion is an important raw material for chemical production, which is widely used in coatings, adhesives, textile printing and other fields. Due to its flammable and toxic properties, it is necessary to strictly comply with relevant regulations during storage and transportation to ensure safety. This article will detail the safety storage and transportation specifications of styrene-acrylic emulsion.

1. styrene-acrylic emulsion physical and chemical properties and risk overview

styrene-acrylic emulsion is a kind of styrene and acrylate monomer copolymer of emulsion, is flammable, toxic substances. The main hazards include: flammability, toxicity, corrosion and reactivity. Therefore, special attention is required during storage and transportation.

2. styrene-acrylic emulsion storage specifications

1. The storage place should choose a dry, ventilated, cool place, avoid direct sunlight and high temperature.
2. The storage container shall be a container with good sealing performance to prevent leakage and volatilization.
3. The storage area should be away from fire and heat sources, and smoking and open fire operations are prohibited.
4. The storage area shall be regularly inspected for safety, including the tightness of the container and the safety of the storage environment.

3. styrene-acrylic emulsion transport specification

1. transport vehicles should comply with the relevant standards, with fire, explosion, leakage and other safety measures.
2. During transportation, it should be kept stable to avoid violent vibration and collision.
3. Keep away from fire and heat sources during transportation. Smoking and open fire operations are prohibited.
4. Transportation personnel shall have relevant qualifications and operation skills, and be familiar with the safety properties and transportation specifications of styrene-acrylic emulsion.

4. styrene-acrylic emulsion leakage emergency treatment measures

1. immediately cut off the leakage source, close the valve or take other measures to prevent leakage continue to leak.
2. Absorb the spill with a mixture of sand, dry lime or soda ash and collect it in a closed container.
3. In case of a large amount of leakage, personnel from the contaminated area shall be evacuated to the safe area, isolated and strictly restricted. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and protective clothing. Cut off the leak source as much as possible. Prevent from flowing into restricted spaces such as sewers and flood drainage ditches. Small amount of leakage: Absorb with sand, vermiculite or other inert material. Can also be washed with a lot of water, wash water diluted into the waste water system. Large leakage: build embankments or dig pits to contain. Cover with foam to reduce steam disasters. Spray water or foam to cool and dilute steam, protect site personnel. Transfer to tank truck or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.

5. fire suppression methods

move the container from the fire to an open area as much as possible. Spray water to keep the fire container cool until the end of the fire. Containers in a fire scene that have discolored or produced sound from the safety pressure relief device must be evacuated immediately. Extinguishing agent: atomized water, foam, dry powder, carbon dioxide, sand. Fire extinguishing with water is ineffective.

6. safety protection measures

respiratory system protection: when the concentration in the air exceeds the standard, you should wear a self-priming filter gas mask (half mask). In case of emergency rescue or evacuation, it is recommended to wear air respirator or oxygen respirator. Eye protection: wear chemical safety goggles. Body protection: wear anti-poison penetration overalls. Hand protection: wear latex gloves. Other protection: smoking, eating and drinking are prohibited at the work site. After work, shower and change clothes. Maintain good hygiene habits.

In short, styrene-acrylic emulsion is an important raw material for chemical production, and its safe storage and transportation are very important. Relevant units and individuals shall strictly abide by relevant specifications to ensure safety.
