The proper storage of construction chemicals is a critical component in ensuring both construction safety and material performance. The core principles involve classification and segregation, environmental control, and standardized management; any improper storage practices could trigger fires, toxic exposure, or hazardous chemical reactions.
Classify by Nature and Strictly Segregate Storage Zones
Construction chemicals should be scientifically classified based on their hazardous properties to prevent the risks associated with mixed storage:
Flammable Substances (e.g., diluents, resin solutions): Should be stored in a cool, well-ventilated area, kept away from ignition sources and heat sources, and housed in explosion-proof cabinets.
Corrosive Substances (e.g., acidic or alkaline admixtures): Must be placed in specialized corrosion-resistant cabinets to prevent the erosion of metal components and must be kept segregated from organic materials.
Oxidizers (e.g., peroxide initiators): Must not be stored alongside reducing agents or flammable materials to prevent violent oxidation reactions.
Toxic Substances (e.g., chromium-containing retarders): Require a "dual-person, dual-lock" management protocol and must be accompanied by emergency equipment, such as gas masks.
Control the Storage Environment to Ensure Physical Conditions Meet Standards
The temperature, humidity, lighting, and ventilation of the storage facility directly impact the stability of the chemicals:
Temperature Control: Warehouse temperatures should ideally be maintained within the range of 5°C to 30°C. During hot seasons, air conditioning or sprinkler systems can be utilized to lower temperatures, and direct sunlight exposure must be avoided.
Humidity Management: Relative humidity should not exceed 80% to prevent moisture absorption, caking, or deliquescence-a precaution that is particularly critical for powdered admixtures (such as accelerators).
Ventilation Requirements: A mechanical ventilation system must be installed to ensure that the concentration of flammable gases remains below one-quarter (1/4) of the Lower Explosive Limit (LEL). Exhaust ducts should be constructed from non-combustible materials and properly grounded to prevent static electricity accumulation.
Explosion Prevention Measures: Flooring should be constructed using non-sparking epoxy resin materials; all electrical equipment must be of the explosion-proof type; and the warehouse facility should be a standalone structure with no basement levels.
