Hazardous Chemical Identification

The identification of hazardous chemicals is based on the characteristics of the chemical (compound, mixture or element) itself and relevant standards to determine whether it is a hazardous chemical and to delineate possible hazard categories and categories.
According to Article 3 of the "Regulations on the Safety Management of Hazardous Chemicals" (State Council Order No. 591), the term "hazardous chemicals" as mentioned in these regulations refers to highly toxic chemicals and other chemicals that are poisonous, corrosive, explosive, burning, combustion-supporting, etc., and are harmful to the human body, facilities, and the environment.
In hazardous chemicals identification cases, Zhongke Testing can provide hazardous chemicals identification services.

1. Material property identification: Test and evaluate the physical properties, chemical properties, explosion properties, etc. of chemical substances to determine their characteristics and performance.
⒉Composition analysis: Use chemical analysis methods to analyze the composition of chemical substances to determine their main components and impurities.
3. Hazard assessment: Based on the nature and composition of the substance, evaluate the toxicity, corrosiveness, explosiveness and impact on the environment of chemical substances, and determine their hazard level.
4. Relevant regulatory compliance assessment: According to relevant national and local regulations and standards (such as "Hazardous Chemicals" concentration limits, necessary labeling and documentation requirements, etc.

was commissioned by an emergency management agency to conduct identification and analysis on whether the liquid suspected of being methanol fuel involved was a hazardous chemical.
quality analysis results:
The quality analysis expert team conducted a sampling investigation and inspection of the "suspected methanol fuel liquid" involved in the case, conducted a comprehensive quality technical analysis, and made the following recommendations and conclusions:
According to the gas chromatograph test results, the methanol content detected in the suspected methanol fuel liquid was 99.5%. The flash point of the suspected methanol fuel liquid is 10.0°C. According to the "Safety Specification for Chemical Classification, Warning Labels and Warning Statements Flammable Liquids" (GB 20581-2006), the suspected gasoline liquid belongs to flammable liquid category 1 and complies with the regulations of flammable liquids in the "Catalogue of Hazardous Chemicals" (2022 Adjusted Edition) and is a hazardous chemical.
