Safe Storage and Transportation Specification
of Hydroxyethyl Methacrylate
1. Introduction

Hydroxyethyl methacrylate (HEMA) is an important chemical raw material, widely used in polymers, coatings, adhesives and other fields. Due to its unique chemical properties, HEMA requires special safety measures during storage and transportation. This article will detail HEMA's safe storage and transport specifications.

2. the physical and chemical properties of HEMA

Hydroxyethyl methacrylate (HEMA) is a colorless and transparent liquid with a strong pungent odor. Its molecules contain carbon, hydrogen, oxygen and other elements, with a certain degree of toxicity and corrosion. HEMA is easily soluble in water, ethanol and other solvents, sensitive to light, heat, oxygen, etc., prone to polymerization.

3. HEMA's safe storage specifications

1. Storage facilities: HEMA should be stored in a cool, dry, well-ventilated dedicated warehouse, avoid direct sunlight and high temperature environment.
2. Storage container: HEMA should be stored in a special stainless steel or plastic container, avoiding the use of iron, aluminum and other metal containers to prevent chemical reactions.
3. Storage identification: The name of HEMA, hazard identification and safety precautions shall be clearly marked on the storage facilities and outer packaging.
4. Storage management: A sound HEMA storage management system should be established, including records such as warehousing, outbound and inventory, to ensure that the accounts are consistent.

4. HEMA's safe transportation specifications

1. Transportation vehicles: HEMA should use special dangerous goods transportation vehicles for transportation. The vehicles should meet relevant national standards and have corresponding dangerous goods transportation qualifications.
2. Transport packaging: HEMA packaging should comply with the national dangerous goods packaging specifications, with sufficient strength and sealing to prevent leakage and damage.
3. Transport identification: The name of HEMA, hazard identification and safety precautions shall be clearly marked on the transport vehicle and outer packaging.
4. Transportation route: Choose a safe transportation route and avoid passing through sensitive areas such as densely populated areas and water source protection areas.
5. Transport personnel: transport personnel should have the corresponding qualification and safety awareness of dangerous goods transportation, and be able to master HEMA's transportation safety knowledge and operation skills after professional training.

5. HEMA's safety operation specification

1. Operators: Operators should be professionally trained to understand the nature and safety operation procedures of HEMA, and have corresponding safety awareness and operation skills.
2. Operating environment: The operating environment shall comply with national safety standards and be equipped with appropriate ventilation and fire fighting facilities.
3. operation process: in the operation process should strictly abide by the safety operation procedures, to avoid leakage, splash and other safety accidents. In case of leakage, corresponding measures shall be taken immediately for disposal.

6. Emergency Treatment Measures

1. Skin contact: If you accidentally come into contact with HEMA, you should immediately take off the contaminated clothes, rinse with plenty of flowing water for at least 15 minutes, and seek medical treatment.
2. Eye contact: If you accidentally come into contact with your eyes, you should immediately lift your eyelids, rinse thoroughly with a large amount of flowing water or normal saline for at least 15 minutes, and seek medical treatment.
3. Inhalation: If you accidentally inhale HEMA vapor, you should quickly leave the scene to a place with fresh air to keep the respiratory tract unobstructed. If you have difficulty breathing, you should seek medical treatment immediately.
4. Ingestion: If you accidentally ingest HEMA, you should drink plenty of warm water immediately and seek medical treatment after vomiting.

7. conclusion

hydroxyethyl methacrylate (HEMA) as an important chemical production raw material, in the process of storage, transportation and operation need to strictly abide by the corresponding safety regulations to ensure the safety of personnel and environment. By strengthening safety management and improving the safety awareness and skill level of operators, the risk of safety accidents can be effectively reduced and the smooth progress of production activities can be ensured.
