A potentially explosive atmosphere exists when a mixture of air, gases, vapours, mists or dust combines in a way that can ignite under certain operating conditions. Hydrogen is the special gas in this context. Those who have knowledge of the properties and flammability of hydrogen will recognize that hazards due to explosive atmospheres must be assessed more and more frequently as the element is utilized, and, if necessary, appropriate protective measures must be taken. In this kind of atmosphere, special attention should be given to the mechanical equipment that are being used for operational purposes, as they might initiate an explosion. Mechanical equipment used in explosive atmospheres should be assessed through an ignition hazard assessment. They must fulfil the essential health and safety requirements, which implies that they shall be assessed according to their ability to prevent them from becoming ignition sources and their ability to protect against the consequences of an explosion.
This paper presents the issue of the ignition hazard assessment of mechanical equipment and points out some aspects that may be important to consider when assessing mechanical systems for use in potentially explosive atmospheres. Ignition of explosive atmospheres by mechanical equipment occurs when energy supplied by equipment is converted into heat, usually as the result of a mechanical failure of the equipment or associated systems. The ignition hazard assessment procedure also involves a series of specific laboratory tests. These tests demonstrate the non-sparking character of the materials used in the manufacture of mechanical equipment and the fact that the assessed equipmen |
