Pressure measured relative to atmospheric pressure. Most pressure gauges read gauge pressure (not absolute pressure).
GCCA (Cold Chain Certification)
Definition: Industry-specific cold chain certification under development by the Global Cold Chain Alliance (GCCA). Aims to provide a comprehensive standard specifically designed for temperature-controlled logistics operations. Why It Matters: A dedicated cold chain certification would provide industry-specific standards beyond general food safety schemes. GCCA membership provides early access to developments and input opportunities. Proposed Scope:– Cold storage facilities– Refrigerated transport–…
GDP (Good Distribution Practice)
Quality system focused on ensuring pharmaceutical products are consistently stored, transported, and handled under suitable conditions as required by regulatory authorities.
Gel Pack (Ice Pack)
Reusable refrigerant pack containing water, gel, or phase-change material, frozen and used for passive cooling in insulated containers.
GFSI (Global Food Safety Initiative)
Definition: Global Food Safety Initiative. An industry-driven initiative providing benchmarking for food safety standards, enabling mutual recognition between certified schemes and reducing audit duplication in global supply chains. Why It Matters: Major global and South African retailers require GFSI-recognized certification from supply chain partners. GFSI certification demonstrates internationally accepted food safety credentials. Essential for cold chain operators serving major retail…
GMP (Good Manufacturing Practice)
Quality assurance system ensuring products are consistently produced and controlled according to quality standards. Foundation for ISO 22000 and pharmaceutical manufacturing.
GPRS Tracking (Cellular Monitoring)
Temperature monitoring system using cellular network (2G/3G/4G/5G) to transmit data from refrigerated vehicles or containers to cloud platform in real-time.
Green Cold Chain
Definition: Holistic approach to cold chain sustainability encompassing energy efficiency, natural refrigerants, renewable energy, reduced emissions, and minimal environmental impact throughout temperature-controlled logistics operations. Why It Matters: Growing customer demand for sustainable logistics. Regulatory pressure on emissions and refrigerants. Long-term cost savings through efficiency. Competitive differentiation and ESG reporting requirements. Key Components:– Energy Efficiency: Optimized refrigeration, insulation, operations– Natural Refrigerants:…
GWP (Global Warming Potential)
Measure of how much heat a greenhouse gas traps in the atmosphere compared to CO₂ over specific time period (typically 100 years). GWP of CO₂ = 1 (baseline).
HACCP
Definition: Hazard Analysis and Critical Control Points. A systematic, science-based approach to food safety that identifies, evaluates, and controls hazards throughout the food production and handling process. Why It Matters: HACCP is the foundation of modern food safety management. Required by R638 regulations, retail customers, and export markets. Forms the basis for more comprehensive standards like ISO 22000 and FSSC…
