Ethyl acetate threat and risk assessment
1. Characteristics of ethyl acetate
Ethyl acetate, also known as ethyl acetate, has a special aromatic taste and is a colorless and transparent liquid. Its boiling point is about 77.1 ° C, flash point is -4 ° C, and it is a flammable liquid. It can form an explosive mixture with air, and can cause combustion and explosion in case of open flame and high heat.

2. Hazard identification
1. ** Health hazards **
-Inhalation: Inhalation at higher concentrations can cause eye, nose and throat irritation symptoms, and in severe cases, it can cause pulmonary edema, coma, etc. Long-term exposure can cause neurological disorders, such as headache, dizziness, fatigue, etc.
- Skin Contact: Can cause skin degreasing, dryness, chapping.
- Ingestion: Accidental ingestion can irritate the mouth, throat, gastrointestinal tract, causing nausea, vomiting, abdominal pain and other symptoms.
2. ** ENVIRONMENTAL HARMENTS **
Ethyl acetate is discharged into the environment and has certain hazards to the ecological environment such as water and soil. It can participate in photochemical reactions in the atmosphere and have adverse effects on air quality.

III. Analysis of exposure pathways
1. ** Exposure during production **
In the ethyl acetate production workshop, workers can inhale volatile ethyl acetate through breathing, and the skin may also come into contact with leaked materials.
2. ** Storage and transportation exposure **
Poor sealing of storage containers or leakage during transportation, surrounding personnel are at risk of inhalation or contact, and leaking substances may contaminate the environment.

IV. Threat and risk assessment
1. ** Possibility assessment **
Under normal production, storage and transportation conditions, the possibility of leakage and personnel exposure is low, but equipment aging, operation errors, etc. may increase the risk. For example, a factory has caused ethyl acetate leakage due to pipeline aging and rupture, causing discomfort to surrounding personnel.
2. ** Severity Assessment **
Once a leak causes a fire and explosion, it will cause serious casualties, property damage and environmental pollution; long-term low-dose exposure of personnel may also cause chronic health problems.

V. Risk Control Measures
1. ** Engineering Control **
- Production equipment is airtight and automated to reduce the chance of material volatilization and personnel contact.
- The storage site is equipped with good ventilation, fire protection and explosion-proof facilities, and is equipped with leakage emergency treatment devices.
2. ** Management Control **
- Formulate and improve safety operation procedures, strengthen staff training, and improve safety awareness and operation skills.
- Conduct regular maintenance and safety inspections of equipment to detect and deal with potential hazards in a timely manner.
3. ** Personal Protection **
Equip operators with appropriate personal protective equipment, such as gas masks, protective gloves, etc., and ensure proper use.
