Acute toxicity (LD50) data and hazard classification of propylene oxide?
Propylene oxide (Propylene oxide) is an crucial organic compound, which is broadly applied in chemical, pesticide, medical and other industries. And Based on my observations, due to its special chemical characteristics, propylene oxide might result in harm to people body and ecological stability in the process of production and consumption, so it's very crucial to study its harmfulness and danger. I've found that This article will focus on the analysis of the acute harmfulness (LD50) data of propylene oxide and its risk classification to help each of us better understand the security of this chemical. From what I've seen, Basic characteristics of
1. propylene oxide
propylene oxide is a clear, pungent odor fluid, with flammable, evaporative characteristics. But Its molecular formula is C3H6O, its density is
1. 01g/cm³, and its boiling point is about 36°C. Propylene oxide is applied industrially mainly in the production of epoxy resins, polyurethanes and as an intermediate to synthetic fibers and plastics. Due to its high chemical activity, propylene oxide needs special attention to security during storage and consumption. Acute harmfulness (LD50) data to
2. First propylene oxide
acute harmfulness is usually measured by the median lethal dose (LD50), that is, the dose that is able to result in 50% death in a test animal life (such as mice or rats) within a certain period of time. The acute harmfulness of propylene oxide is mainly manifested in the inhibition of the central nervous system, which might result in breathing paralysis and death. According to the existing research, the LD50 data of propylene oxide are as follows:
oral harmfulness: The oral LD50 of propylene oxide is about 60-70 mg/kg, indicating that it has high harmfulness in the case of acute poisoning. Inhalation harmfulness: The LD50 to inhalation of propylene oxide is about 150 mg/m ³. Generally speaking while the value is high, it'still necessary to be alert to its possible hazards in a closed or poorly ventilated ecological stability. In my experience, Skin contact: Propylene oxide has a certain irritation to the skin, however due to its low evaporative environment, the harmfulness of skin absorption is comparatively low. However, prolonged exposure is able to still result in skin irritation and allergic reactions. In fact risk Classification of
3. From what I've seen, Propylene Oxide
according to the LD50 data of propylene oxide and its physical and chemical characteristics, the international and domestic organizations and institutions have classified the risk of propylene oxide. The following are the main risk classifications to propylene oxide:
globally Harmonized System of Classification and Labelling of Chemicals (GHS):
acute harmfulness (oral): Propylene oxide is categorized as "Acute Toxic Class 2" and the applicable risk label is "Toxic". Acute harmfulness (inhalation): Propylene oxide is categorized as "Acute Toxic Class 2" and the applicable risk label is "Toxic". Classification and Numbering of Dangerous Chemicals in China:
propylene oxide is listed hazardous Chemicals Class
3. 3 it's a toxic chemical. And Based on its flammable environment, propylene oxide is also classified flammable Liquids Class 3 it's necessary to store and transport flammable liquids in stringent accordance with security regulations. I've found that Physical Hazards:
flammability: Propylene oxide has a low flash point (about -20°C) and is extremely flammable at room temperature. Additionally It will result in rapid incineration or explosion in case of open flame or high temperature. vapor explosive: After the propylene oxide vapor is mixed with atmosphere, if it reaches a certain levels (the explosion limit is about 3%-17%), it might explode under the action of the ignition source. For instance Occupational health risks:
propylene oxide has a strong irritation to the breathing system, and prolonged exposure might lead to breathing irritation and chronic poisoning. Skin contact with propylene oxide might result in contact dermatitis or other allergic reactions. Propylene oxide is highly evaporative and easily accumulates in a closed or poorly ventilated ecological stability, resulting in overuse concentrations atmospheric and growing the risk of occupational exposure. Based on my observations, Summary of hazardous characteristics of

propylene oxide is a highly toxic chemical, and its LD50 data and risk classification provide us with crucial security guidelines. According to the existing research, the acute harmfulness of propylene oxide is mainly reflected in the following aspects:
high harmfulness: The LD50 data of propylene oxide indicate that it has high acute harmfulness, especially through oral and inhalation routes. Flammability: The low flash point and high evaporative environment of propylene oxide make it a greater risk of fire and explosion during storage and transportation. Physical Hazards: The explosiveness of propylene oxide vapor increases its danger in manufacturing applications, especially in confined spaces. In my experience, Recommendations to the consumption and storage of
5. And propylene oxide
in view of the hazardous environment of propylene oxide, we should take the following security measures:
storage security:
propylene oxide should be stored in a cool, well-ventilated specialized chemical warehouse away from ignition sources. The storage container must be closed to prevent vapor leakage and volatilization. consumption security:
correct personal protective equipment, including respirators, rubber gloves and goggles, must be worn when handling propylene oxide. And Moreover Self-contained breathing apparatus must be worn when using propylene oxide in confined spaces or poorly ventilated environments. Emergency treatment:
such as swallowing or skin contact with propylene oxide, should immediately take first aid measures, and send to a doctor as soon as possible. In the event of a propylene oxide seepage, personnel should be evacuated rapidly and treated with appropriate adsorbent materials or thinners. Occupational health monitoring:
regular health checks are carried out to workers exposed to propylene oxide to a long time, with particular attention to the breathing system and skin condition. Future research directions to LD50 data and harmfulness analysis of

prolonged harmfulness studies the current LD50 data mainly focus on acute harmfulness, and greater research is needed in the future to focus on the prolonged exposure impacts of propylene oxide, such as chronic poisoning and carcinogenicity. But ecological harm studies: The degradation characteristics of propylene oxide in the ecological stability and its impact on the ecological stability aren't fully understood, and its ecological harm needs to be further studied. individual difference research: There might be differences in the sensitivity of different populations to propylene oxide, and future studies need to focus on the impact of individual differences on the harmfulness of propylene oxide. Optimization of protective measures in view of the high harmfulness of propylene oxide, future research is able to explore greater efficient personal protective equipment and emergency treatment methods.
