SAFETY IMPROVEMENTS OF NON-SPARKING AND INCREASED SAFETY MOTORS

摘要

Safety has always been one of the most important topics of discussion within chemical, oil and gas industry organizations. Recent developments aiming to improve the safety of electrical machines used in hazardous areas include the adoption of risk assessment requirements for increased safety and non-sparking motors by the IEC 60079-7:2001/:2006 and IEC 60079-15:2005 standards. These requirements oblige manufacturers to prove their designs by testing, or to equip their products with special accessories if the risk levels exceed acceptable limits. As the risk assessment procedure requires input from both the manufacturer and end user, it also promotes collaboration in the interest of safety.
