Abstract

Engineering laboratories serve as vital venues for practical engineering education and scientific research innovation in universities. However, safety hazards in these settings are often highly concealed and difficult to detect in advance, characterized by the intersection of multiple risks. Currently, laboratory safety inspections face three prominent issues: the disconnection between inspection and rectification, a lack of targeted control standards, and insufficient support from information technologies. Integrating the theories of hierarchical risk control and grid-based governance, this study constructs a laboratory safety governance system based on the “Three-Tier Four-Dimension” model. Grounded in micro-grid responsibility management and supported by a lightweight information platform, this system organically integrates three progressive tiers—risk identification, classified governance, and comprehensive supervision—with differentiated control measures for four types of laboratories: electrical, mechanical, telecommunications, and computer rooms. This forms a complete governance closed loop of “discovery–governance–supervision–verification. “Using the Engineering Experimental Center of Guangzhou College of Technology as an empirical sample, the practical application demonstrates that after implementing the system, the hazard rectification completion rate increased from 58.9%to 95.5%, the average rectification cycle was reduced from 8.6 days to 3.2 days, and the recurrence rate of similar hazards decreased from 62.7%to 34.7%. Furthermore, the comprehensive pass rates for specialized inspections across all four types of laboratories exceeded 95%. The “Three-Tier Four-Dimension” model provides a practical reference for the safety governance of multi-type mixed engineering laboratories.
