[The National Survey on Working Conditions: data for reflection]

Area of Science:

• Occupational Health and Safety
• Industrial Hygiene
• Ergonomics

Background:

• The National Survey on Working Conditions in Spain (1993) provides critical data on workplace hazards.
• A significant gap exists between identified occupational risks and implemented preventive measures.

Purpose of the Study:

• To analyze the prevalence of occupational risks and preventive activities in Spanish industry and services sectors.
• To investigate worker exposure to physical and chemical agents, and ergonomic stressors.
• To examine the relationship between work conditions and worker morbidity, particularly posture problems.

Main Methods:

• Cross-sectional survey of 3,148 workers in Spanish industry and services sectors.
• Data collection through individual interviews at the workplace and questionnaires.
• Analysis of findings by activity sector and detailed morbidity assessment.

Main Results:

• Only 11.8% of companies conducted occupational risk surveys.
• High worker exposure rates: 59% to accident risks, 33% to noise, 32% to chemical substances.
• Approximately 50% of workers experienced prolonged static postures or repetitive hand-arm movements.
• 60% of workers reported posture problems linked to their jobs.
• High work rates or short-cycle repetitive tasks affected an estimated 60% of workers.

Conclusions:

• Workplace preventive activities are notably lacking despite high exposure to occupational hazards.
• Ergonomic factors, including static postures and repetitive movements, significantly contribute to worker morbidity.
• Worker perception of their work environment is crucial for effective occupational health and safety strategies.
