T/JYBZ 018-2021 Secondary and elementary school hazardous chemical storage cabinets technical specifications

Scope

Scope: This document specifies the basic requirements for dangerous chemical cabinets in primary and secondary schools, including terms and definitions, classification, general requirements, special requirements, test methods, marking, packaging, and usage instructions, etc. This document is mainly applicable to dangerous chemical cabinets for precursor chemicals and explosive precursors in primary and secondary schools. Other dangerous chemical cabinets in primary and secondary schools can be referred to as appropriate. Main technical content: The preparation of this standard fully investigated the properties, classification, storage, and related safety management requirements of dangerous chemicals, as well as the current technical status of dangerous chemical cabinets. Relevant domestic and foreign materials were consulted, and experimental verification of key performance indicators was organized. Relevant process indicators in actual production were also referenced to make the standard content and indicators more in line with actual needs. Based on the nature of stored dangerous chemicals, primary and secondary school dangerous chemical cabinets are divided into corrosion-resistant safety cabinets and fire-resistant safety cabinets. Among them, the corrosion resistance of corrosion-resistant safety cabinets is mainly achieved through the lining of high-molecular materials (corrosion-resistant materials) and the design of the shell with certain corrosive properties; fire-resistant safety cabinets combine FM 6050, EN 14470-1:2004, and the current achievable levels of domestic products, and requirements for the fire resistance time and temperature rise of the cabinets are also proposed.
