NOM-009-STPS is a critical Mexican standard that outlines safety requirements for work performed at height, specifically when the working surface is 1.80 meters or higher above a reference level or near unprotected edges. The standard was established to minimize the risks associated with falls, which are a leading cause of workplace injuries and fatalities. It encompasses a range of safety measures including the implementation of fall protection systems, which must include personal protective equipment (PPE) such as harnesses, lifelines, and properly installed anchor points. Moreover, the standard mandates the use of scaffolding, portable ladders, and mobile elevated work platforms (MEWPs) to ensure that workers can safely access elevated work areas.
The 2023 revision of NOM-009-STPS introduced significant updates, particularly regarding the competency requirements for MEWP operators. This change reflects the growing recognition of the need for specialized training to ensure that operators are fully qualified to handle the complexities and risks associated with operating MEWPs. The standard also emphasizes the importance of rescue training, ensuring that all personnel involved in work at height are prepared for emergency situations, which may involve retrieval of a worker who has fallen or is otherwise incapacitated at height.
Additionally, NOM-009-STPS specifies that when perimeter guardrails are not feasible, alternative fall protection strategies must be employed. This includes the proper installation and maintenance of safety systems to prevent falls and to provide effective rescue measures. Compliance with this standard is not just a regulatory requirement but also a critical aspect of workplace safety culture that protects workers and enhances overall operational efficiency in industries where work at height is commonplace.
