What equipment is needed in a hazardous waste temporary storage area for storing chemicals?

Thread Content

A hazardous waste storage area for chemicals must meet five key requirements: the \"six protections\" (protection from wind, rain, sunlight, leakage, seepage, and corrosion), explosion safety, proper classification and separation, fire emergency preparedness, and proper labeling. I. Construction and Sealing (Core Foundation) #Jingye Environmental Protection • Independent Enclosure: Dedicated buildings that are separated from production, office, and living areas. #Hazardous chemicals storage area • Ground impermeability: hardening + anti-corrosion impermeabilization (epoxy resin/HDPE membrane), with a permeability coefficient ≤10⁻¹⁰ cm/s. • Curb protection: At least 1.2m in height, with waterproof and anti-corrosion properties; the entire wall in corrosive areas shall be treated accordingly. • Overflow barrier: A liquid barrier with a height of ≥15–30 cm is installed at the entrance. • Conveyance and collection: ground slope (≥2%) → diversion ditch → liquid collection tank (≥maximum leakage volume per bucket). II. Electricity and Ventilation (explosion-proof is mandatory) • Fully explosion-proof: lighting, switches, fans, sockets, electrical control boxes, and cameras are all of explosion-proof type. Forced ventilation: ◦ General: ≥3 air changes per hour ◦ Volatile substances/VOCs: ≥6 air changes per hour • Gas monitoring: combustible/toxic gas detectors, thermohygrometers. III. Classified Storage and Containers (Key to Compliance) • Zonal Separation: Acids/bases, flammable/oxidizing/toxic substances – separate by physical partitions/independent enclosures. • Stacking specifications: ◦ Minimum height from the ground: 15 cm, minimum distance from the wall: 50 cm, minimum width of aisles: 80 cm. ◦ Maximum stack height: 3 m; a maximum of 2 layers of barrels are allowed. • Container requirements: properly sealed, made of compatible materials (HDPE/steel barrels), with no damage or leaks. • Label: Attach national standard hazardous waste labels to each barrel (name, code, hazard characteristics, date). IV. Fire Protection and Emergency Response (Life-saving Equipment) • Fire extinguishing equipment: dry powder fire extinguishers, fire sand, fire blankets. • Leak prevention: leak-proof trays (≥1.1 times that of a single barrel), oil-absorbing cotton/sponges, leak-sealing tools, emergency barrels. • Emergency flushing: eye wash station + emergency shower (essential in corrosive areas). • Personal protection: acid and alkali resistant gloves, protective clothing, goggles, gas mask. V. Identification and Management (Key inspection points) • External identification: Hazardous waste warning signs (≥40×40 cm), “No entry for unauthorized persons”. • Internal announcements: ◦ Posting of management systems and emergency plans ◦ Designated persons, contact numbers, and emergency phone numbers ◦ Categories of hazardous waste and maximum storage amounts • Records: inventory entry/exit records, transfer forms, and generation records. • Access control: double locks for two people, managed by a dedicated person. VI. Basis for core standards • GB 18597-2023 \"Standards for Pollution Control in the Storage of Hazardous Wastes\" • HJ 1276-2022 \"Specifications for Labelling of Hazardous Wastes\"
