Case Study Context: Critical Challenges in the Energy Sector
The studied company, a power generator with 2,400 employees distributed across five thermal plants, faced critical occupational safety challenges that threatened both Law 29783 compliance and operational continuity.
Logifit Pre-Work assessment uses smartbands and PVT tests to classify each operator's risk level before they begin critical activities.
Critical Data: Energy companies register 4.2 incidents per 100,000 hours worked during night shifts, according to Ministry of Energy and Mines 2024 data.
The initial situation revealed concerning patterns in their safety KPIs. Records from the previous 24 months showed an upward trend in incidents related to operational fatigue, especially during critical hours from 2:00 AM to 6:00 AM, when heat stress and drowsiness combined to create high-risk conditions.
Pre-Implementation Safety KPIs Baseline
Initial indicators showed an incident rate of 3.8 per 100,000 hours worked, with 67% occurring during night shifts. Causal analysis identified fatigue as a contributing factor in 73% of recorded cases.
Regulatory pressure intensified when SUNAFIL scheduled surprise audits focused on SG-SST compliance. The company needed a solution that would not only reduce real risks but also provide the documentary traceability required by Peruvian regulations.
| Baseline Indicator | Initial Value | SG-SST Target |
|---|---|---|
| Incident Rate | 3.8/100,000 hh | <2.0/100,000 hh |
| Night Incidents | 67% | <40% |
| Lost Days/Year | 180 | <90 |
SG-SST Implementation: Real Methodology and Timeline
Implementation followed a three-phase approach specifically designed to meet Law 29783 requirements while minimizing operational disruption. This case study documents each stage with timelines, assigned resources, and intermediate results.

Phase 1: SG-SST Diagnosis and Planning (Months 1-3)
Comprehensive risk assessment according to DS 024-2016-EM, identification of critical positions, hazardous process mapping, and implementation plan development with detailed timeline and management-approved budget.
During Phase 1, the project team conducted an exhaustive evaluation using the IPERC (Hazard Identification, Risk Evaluation and Control) methodology required by regulations. Twenty-three critical work positions were identified where fatigue and heat stress presented high or very high risk.
Organizations implementing comprehensive fatigue management achieve 42% reduction in safety incidents within the first 18 months, according to ICMM 2024 research.
Phase 2 (months 4-8) focused on technological and procedural implementation. The preventive biometric monitoring system was installed in all 23 critical positions, 100% of personnel were trained in new SG-SST procedures, and automatic response protocols were established for fatigue detection.
- System installation and calibration: 45-day actual timeline, including pilot tests at two plants before complete rollout
- Massive personnel training: 180 training hours distributed in 4-hour sessions to minimize operational impact
- Integration with existing systems: Connection with SCADA, access control systems, and human resource management platforms
- Emergency protocol establishment: Specific procedures for each alert level detected by the system
Quantified Results: Post-Implementation ROI and Safety KPIs
Results from this case study demonstrate measurable impact on both safety KPIs and financial indicators. Continuous monitoring during 18 months post-implementation provides robust data on the effectiveness of the implemented SG-SST.
Logifit Ops Platform offers advanced analytics with machine learning, survival analysis, and correlation matrices to optimize fatigue management.
Key fact: The 35% reduction in fatigue-related incidents translated to $2.4 million USD savings in direct and indirect costs, according to audited financial analysis.
The 340% ROI was calculated considering all implementation costs ($180,000 USD) against quantifiable benefits over an 18-month horizon. Benefits included insurance premium reduction, elimination of SUNAFIL fines, reduction of lost days, and improvement in operational efficiency. (Source: McKinsey — Mining Insights)
Calculated ROI Breakdown
Total benefits: $612,000 USD (direct cost savings $240,000 + indirect $180,000 + insurance premiums $95,000 + avoided fines $97,000). Total investment: $180,000 USD. ROI = (612,000 - 180,000) / 180,000 = 340%.
Safety KPIs showed consistent improvements starting from the fourth month of implementation. The incident rate decreased from 3.8 to 2.1 per 100,000 hours worked, exceeding the established target of 2.0. More significantly, night shift incidents reduced from 67% to 31% of the total.
- Reduction in night incidents: From 67% to 31% of total, practically eliminating critical events between 2:00 AM and 6:00 AM
- Response time improvement: Preventive alerts reduced average emergency response time from 4.2 to 1.8 minutes
- Regulatory compliance: 100% compliance in three SUNAFIL audits conducted during the follow-up period
- Personnel satisfaction: 89% of operators reported greater confidence and well-being during their work shifts
Compliance Analysis: Law 29783 and Energy Sector Regulations Adherence
This case study documents how the implemented SG-SST ensured comprehensive compliance with Law 29783 and specific Peruvian energy sector regulations. The systematic approach enabled passing three SUNAFIL audits without critical observations.
Law 29783 requires implementation of a Safety and Health Management System that includes specific elements of prevention, control, and continuous improvement. In the energy sector, these requirements are complemented by DS 024-2016-EM, which establishes additional requirements for operational risk management.
Documented Compliance Elements
The implemented system covered the four pillars of Law 29783: policy and objectives, planning, implementation and operation, verification and continuous improvement. Each element has auditable documentary evidence and complete traceability.
SUNAFIL audits focused especially on the company's ability to demonstrate proactive management of risks related to operational fatigue. The implemented system provided objective evidence of:
- Systematic hazard identification: Updated IPERC matrices with quantitative methodology for fatigue risks
- Real-time risk control: Automatic records of detection, alerts, and implemented corrective actions
- Training and competency: Complete training database with effectiveness evaluations and scheduled refresher training
- Incident investigation: Causal analysis methodology that includes fatigue factors with specific action plans
Implementing a robust SG-SST is not just a legal obligation, but a competitive advantage that transforms safety culture and operational results
