Europe and US maintain distinct machine safety standards, but a migration is beginning.
EU Machinery Directive 2006/42/EC • National laws of the European Union (EU) require that machines meet Essential Health and Safety Requirements (EHSR) • All new machinery must fulfill the same legal requirements when supplied throughout the EU.
Role of 2006/42/EC Defines the Essential Health & Safety Requirements (EHSR) Ensures that a machine is designed and constructed to be safe so that it can be used, configured, and maintained throughout all phases of its life, causing minimal risk to people and environment
