This case study analyzes real implementation at a thermoelectric plant that transformed its safety KPIs through 10 documented best practices. (Source: OSHA — Commonly Used Statistics)
Case Study Regulatory Context: SG-SST Framework Under Decreto 1072
Energy company Termocosta S.A.S. faced critical inspections from Colombia's Ministry of Labor under Decreto 1072. Their safety KPIs showed 23 heat stress incidents in 2023, with potential fines up to 500 SMMLV according to Resolution 0312.
Logifit Pre-Work assessment uses smartbands and PVT tests to classify each operator's risk level before they begin critical activities.
Decreto 1072 Article 2.2.4.6.8
Mandates hazard identification and risk assessment for worker health. In environments with WBGT >28°C, requires specific administrative and technical controls documented within the SG-SST system.
Initial diagnosis revealed critical deficiencies in the system. The hazard matrix lacked quantitative heat stress assessment. Existing controls were reactive, based on worker complaints after evident symptoms appeared.
Critical Data: 78% of energy plants in Colombia operate with WBGT >30°C for 6+ hours daily, according to ACOLGÉN 2024 study
Internal audit identified specific gaps. Absence of continuous vital sign monitoring. Generic hydration protocols without worker-specific personalization. Shift rotation without objective physiological criteria.
| SG-SST Indicator | 2023 Baseline | Decreto 1072 Target |
|---|---|---|
| Heat Stress Incidents | 23 cases/year | <5 cases/year |
| Emergency Response Time | 8.3 minutes | <4 minutes |
| Biometric Monitoring Coverage | 12% workers | 100% workers |
Best Practice #1-3: Preventive Monitoring and Fitness Assessment
Implementation began with preventive technology. Logifit Pre-Work Assessment enabled physiological fitness evaluation before extreme heat exposure, complying with Article 2.2.4.6.15 of Decreto 1072 regarding health surveillance.
Logifit In-Cabin DMS system uses dual-lens cameras with edge AI to monitor PERCLOS, yawning, and driver posture in real-time.
Best Practice #1: Biometric Smartbands
Band 9 implementation for continuous monitoring of core temperature, heart rate, and hydration levels. Data transmitted every 30 seconds to supervisors, automatic alerts when physiological WBGT >32°C.
Results were immediate. In the first month, the system detected 47 pre-heat stress cases, enabling intervention before clinical symptoms. The mobile app generated APTO/NO APTO status based on 12 objective physiological parameters.
Best Practice #2: PVT (Psychomotor Vigilance Test)
Pre-shift reaction time tests identify fatigue that amplifies heat stress risk. Workers with PVT >300ms receive modified shifts in lower caloric exposure areas.
The third practice integrated clinical assessments. The STOP-BANG protocol identified workers with sleep apnea, a condition that increases heat incident risk by 2.4x according to NIOSH. Academia Logifit trained supervisors in biometric data interpretation.
Best Practice #3: Personalized Exposure Matrix
Machine learning algorithm calculates maximum exposure time per worker, considering age, BMI, medications, cardiovascular history, and thermal acclimatization. Daily updates based on smartband data.
Companies implementing preventive biometric monitoring achieve 71% reduction in heat stress incidents during the first year, according to ICMM 2024 study.
Best Practice #4-6: Data-Driven Administrative Controls
Traditional administrative controls failed due to lack of objectivity. The case study implemented a three-tier system based on data science, meeting Resolution 0312 requirements for structure, process, and outcome indicators.
Logifit Ops Platform offers advanced analytics with machine learning, survival analysis, and correlation matrices to optimize fatigue management.
Best Practice #4: Intelligent Shift Rotation
Automatic rotation system based on individual biometric data. Workers with core temperature >37.2°C receive mandatory 20-minute rest in climatized area, automatic replacement by standby personnel.
Implementation required redesign of operational procedures. Each workstation received thermal load classification using WBGT ISO 7243 methodology. The Logifit Ops Platform integrated environmental data with individual biometrics.
Key Fact: Biometric data-based rotations reduce recovery time post-exposure by 43% vs. fixed-time rotations (Safe Work Australia 2024)
The fifth practice transformed hydration management. Generic protocols ("drink every 30 minutes") were replaced by personalized recommendations based on individual sweat rates, measured by smartband bioimpedance.
Best Practice #5: Personalized Hydration
Automatic calculation of fluid needs per worker: [Sweat rate (ml/h) + Insensible loss + Activity factor] × Shift duration. Push alerts when hydration falls <85% of individual optimum.
The sixth administrative control implemented predictive breaks. Instead of fixed 2-hour rest periods, the system scheduled breaks when ML algorithms predicted heat stress risk 15 minutes in advance.
Best Practice #6: ML Predictive Breaks
Machine learning analyzes individual patterns of temperature, heart rate, activity, and environmental conditions. Heat risk prediction with 92% accuracy, automatic breaks 15 minutes before critical point.
Best Practice #7-9: Technology Integration and Emergency Response
The seventh practice revolutionized thermal emergency response. The Logifit DMS system in vehicles detected heat stress signs in drivers, activating automatic emergency protocol when core temperature exceeded 38.5°C.
Best Practice #7: Automatic Emergency Detection
Computer vision algorithm identifies heat stroke symptoms: excessive sweating, facial flushing, erratic behavior. Automatic alert to medical center with exact worker geolocation.
Response results were dramatic. Average medical attention time reduced from 8.3 to 2.1 minutes. Logifit's 24/7 call center coordinated medical evacuation while gathering pre-incident biometric data for more precise diagnosis.
The eighth practice integrated environmental IoT with individual data. WBGT sensors distributed throughout the plant transmitted data every 60 seconds, creating dynamic heat maps that optimized work routes to minimize cumulative thermal exposure.
Best Practice #8: Dynamic Thermal Mapping
Network of 47 IoT sensors creates real-time heat map. Routing algorithm optimizes work trajectories to maintain cumulative thermal exposure <150 WBGT-hour units per shift.
The ninth practice established executive dashboards for regulatory compliance. The Ops Platform generated automatic reports for Ministry of Labor inspections, documenting implemented controls according to Decreto 1072 required structure.
Best Practice #9: Automatic Compliance Reporting
Executive dashboard with real-time KPIs: incident frequency index, average exposure time, preventive control coverage. Automatic export in format required by Resolution 0312.
| SG-SST KPI | Month 1 | Month 6 | Month 12 | Month 18 |
|---|---|---|---|---|
| Heat Stress Incidents | 19 | 12 | 8 | 7 |
| Response Time (min) | 7.1 | 4.2 | 2.8 | 2.1 |
| Heat-Related Absenteeism (%) | 3.4 | 2.1 | 1.2 | 0.8 |
