In Ecuador, the lack of attention to occupational safety in small and medium-sized enterprises, which constitute 98% of the total, has increased workplace accidents. To assess this situation, a Checklist based on the Guide of the National Institute for Occupational Safety and Health (INSHT) of the Ministry of Labor was applied. The methodology was then adapted to evaluate specific working conditions in SMEs and the NTP 330 method was used, which considers criteria such as efficiency, exposure, probability, and consequences to determine the risk level. Fifty-eight hazards were identified, including falls of people from different levels, falling objects due to collapse, and blows or cuts caused by tools, each with an incidence of 10%. The distribution area presented the highest number of risks (15), and the high-risk level predominated. The application of the method allowed for a comprehensive assessment, highlighting the urgent need for preventive measures.

Para evaluar esta situación, se aplicó una Lista de Verificación basada en la Guía del Instituto Nacional de Seguridad y Salud en el Trabajo (INSHT) del Ministerio de Trabajo. Luego, se adaptó la metodología para evaluar condiciones laborales específicas de PYMES y se utilizó el método NTP 330, que considera criterios como eficiencia, exposición, probabilidad y consecuencias para determinar el nivel de riesgo. Se identificaron 58 peligros, destacando la caída de personas a diferentes niveles, caída de objetos por derrumbe y golpes o cortes con herramientas, cada uno con una incidencia del 10 %. El área de distribución presentó el mayor número de riesgos (15) y predominó el nivel de riesgo alto. La aplicación del método permitió una evaluación integral, destacando la necesidad urgente de medidas preventivas.
