The safe use of construction chemicals must be integrated throughout the entire lifecycle-from procurement, storage, and handling to disposal. The core principles involve standardized management, personal protection, and emergency preparedness; any oversight at any stage could trigger incidents involving fire, chemical poisoning, or environmental contamination.
Before Use: Conduct Risk Assessments and Personnel Preparation
Identify Chemical Properties
Before use, it is mandatory to consult the Material Safety Data Sheet (MSDS/SDS) to understand the chemical's flammability, toxicity, corrosivity, and compatibility restrictions. For instance, acids must never be stored alongside bases, as doing so could generate toxic gases or trigger violent chemical reactions.
Conduct Professional Training
All personnel involved in operations must undergo safety training to master the hazardous characteristics of the chemicals, correct handling procedures, and emergency response methods. Untrained personnel are strictly prohibited from performing these duties.
Equip and Inspect Personal Protective Equipment (PPE)
Select appropriate protective equipment based on the specific type of operation:
Head Protection: Wear a safety helmet to guard against falling objects, and pair it with a face shield to protect against chemical splashes.
Eye Protection: Use tightly sealed chemical-resistant goggles to prevent liquid splashes from entering the eyes.
Respiratory Protection: In poorly ventilated environments or areas with excessive dust levels, wear a self-filtering dust mask or a positive-pressure respirator.
Hand Protection: Select nitrile or rubber gloves that offer resistance to chemical corrosion.
Foot Protection: Wear safety footwear resistant to chemical penetration to prevent skin contact.
Body Protection: Wear anti-static workwear during spraying operations, and utilize air-supplied protective suits when working in confined spaces.
