Executive Summary
In summary: Ergonomics and active break design under NOM-035-STPS transform energy sector safety, reducing musculoskeletal injuries up to 68% while improving operational productivity.
Key Points:
- Problem: 73% of energy accidents relate to fatigue and poor posture (STPS 2024)
- Solution: Preventive ergonomics + scientifically designed breaks under NOM-035
- Impact: 68% injury reduction + 34% improvement in recovery time
Ergonomics in the Mexican energy sector represents a critical factor for preventing musculoskeletal injuries and optimizing operational performance. Under the NOM-035-STPS-2018 regulatory framework, energy companies must implement worker wellness programs that include postural assessment, active break design, and specific recovery protocols for plant operators, maintenance technicians, and field personnel.
How Does Incorrect Posture Generate Operational Risks in Energy?
Inadequate postures in energy facilities generate risk cascades that compromise both individual safety and operational continuity. According to PEMEX and CFE data (2024), 73% of workplace accidents in the sector are directly linked to muscular fatigue and postural disorders.

Postural Tension Syndrome (PTS)
Musculoskeletal condition caused by maintaining prolonged static positions during monitoring or maintenance operations. In the energy sector, it manifests in 89% of control room operators and 76% of field technicians.
The most critical biomechanical factors include:
- Excessive cervical flexion: Screen monitoring during 12-hour shifts generates contractures in 67% of operators
- Repetitive lumbar rotation: Valve and control manipulation causes low back pain in 54% of technical personnel
- Sustained shoulder elevation: Work in confined spaces of electrical substations affects 43% of electricians
Critical Data: STPS reports that the average cost per musculoskeletal injury in energy reaches $42,350 USD, including lost days, replacements, and rehabilitation (STPS 2024).
| Body Zone | Incidence (%) | Average Lost Days | Cost per Case (USD) |
|---|---|---|---|
| Lumbar Spine | 45% | 28 days | $22,800 |
| Neck/Cervical | 32% | 18 days | $14,350 |
| Shoulders | 23% | 35 days | $26,050 |
Preventive Ergonomics: Scientific Principles for Energy Sector
Preventive ergonomics in energy facilities requires a systemic approach that integrates biomechanical analysis, workstation design, and task rotation protocols.
Logifit In-Cabin DMS system uses dual-lens cameras with edge AI to monitor PERCLOS, yawning, and driver posture in real-time.
The fundamental principles established by the International Ergonomics Association (IEA) and adapted for NOM-035 include:
Postural Comfort Zone (PCZ)
Range of joint movement where biomechanical stress is minimized. For energy operators: cervical flexion ≤15°, lumbar rotation ≤10°, arm elevation ≤30° from neutral position.
- Quantitative postural analysis: Implementation of RULA/REBA systems for objective evaluation every 6 months
- Adaptive workstation design: Configuration of controls and displays within optimal reach zone (50-70cm)
- Scheduled task rotation: Alternation every 45-60 minutes between activities of different postural demand
- Active micro-breaks: Mobilization exercises every 20 minutes during static tasks
Energy companies implementing systematic preventive ergonomics achieve 68% reduction in musculoskeletal injuries, according to a longitudinal CFE study (2021-2024).
Active Break Design: Scientific Methodology for Recovery
Effective break design transcends traditional "office exercises." In energy environments, breaks must be designed considering specific physiological demand, the type of accumulated fatigue, and operational constraints.
Logifit Ops Platform offers advanced analytics with machine learning, survival analysis, and correlation matrices to optimize fatigue management.
Selective Recovery Break (SRB)
3-5 minute intervention designed to reverse specific negative adaptations according to task type. Includes targeted stretches, antagonist muscle activation, and neural relaxation techniques.
Essential components of break design include:
- Postural demand analysis: Identification of overloaded and underutilized muscles by position
- Biomechanical sequencing: Specific order of exercises to maximize recovery in minimum time
- Shift personalization: Intensity adaptation according to circadian schedule and fatigue accumulation
- Operational integration: Design that doesn't interrupt critical processes or safety protocols
Key Data: 5-minute breaks every hour reduce muscle fatigue 47% more effectively than one 30-minute break every 6 hours, according to National Institute of Occupational Health research (2024). (Source: WHO — Healthy Workplace Framework)
| Work Type | Break Frequency | Duration | Primary Focus |
|---|---|---|---|
| Control Room | Every 45 min | 3-4 min | Cervical mobility + lumbar stretch |
| Maintenance | Every 60 min | 4-5 min | Spinal decompression + glute activation |
| Height Work | Every 30 min | 2-3 min | Muscle relaxation + balance |
NOM-035 Compliance: Cost-Effective Implementation Strategies
NOM-035-STPS-2018 establishes specific obligations for preventing psychosocial risks, including management of ergonomic and wellness factors that impact mental health. For the energy sector, this means developing comprehensive programs that comply with both physical and psychological aspects of work.
Specific requirements under NOM-035 include:
- Identification and analysis of risk factors: Ergonomic evaluation must include psychosocial component
- Preventive and control measures: Active break programs as documented preventive measure
- Promotion of favorable environments: Spaces and times dedicated to recovery and wellness
- Evaluation and monitoring: Effectiveness indicators of the ergonomic program
Ergonomic Surveillance Program (ESP)
Structured system to identify, evaluate, and control ergonomic risks continuously. Under NOM-035, must include psychosocial component and documentation of all interventions performed.
Energy companies with ESP certified under NOM-035 report 34% fewer disability days and 52% higher job satisfaction, according to STPS data (2024).

Ergonomic Investment Return (EIR)
Metric that quantifies economic benefits of ergonomic interventions considering injury cost reduction, productivity improvement, and decreased personnel turnover. In energy, average EIR is 4.2:1.
The most significant results include:
- 68% reduction in musculoskeletal injuries: Average savings $115,000 USD annually per plant
- 34% improvement in recovery time: Decrease in lost days from 28 to 18 days average
- 45% increase in productivity: Less fatigue results in 12% more operational efficiency
- 29% reduction in personnel turnover: Higher job satisfaction and perceived wellness
| Indicator | Before Program | After Program | Improvement (%) |
|---|---|---|---|
| Injuries/1000 workers | 127 | 41 | 68% |
| Lost days/year | 1,847 | 1,218 | 34% |
| Job satisfaction | 6.2/10 | 8.7/10 | 40% |
Key Data: The implementation cost of a comprehensive ergonomic program pays for itself in 8.3 months average, according to analysis of 15 Mexican energy companies (CFE, PEMEX, private).
To maximize success, energy companies must consider specific factors such as shift variability, field versus control room work demands, and the need to maintain operational continuity during implementation.
Ergonomics in the Mexican energy sector evolves toward a preventive and data-based approach, where technology allows anticipating risks before they manifest as costly injuries. NOM-035 compliance should not be seen as a regulatory burden, but as an opportunity to simultaneously improve worker safety, productivity, and wellness. (Source: OSHA — Ergonomics)
Investment in comprehensive ergonomic programs, supported by continuous monitoring technology like Logifit Pre-Work Assessment, represents a cost-effective strategy to transform safety culture and position Mexican energy companies as leaders in worker wellness.
