An explosion vent panel is a safety device that is designed to protect equipment or buildings against excessive internal, explosion-incurred pressures. If an explosion occurs, the pressure will be released (sometimes via a fitted duct) as soon as its activation/opening pressure is reached.
Explosion vent panels Containment Although the provision of explosion relief vents is the most widely used technique for protecting process plant from dust explosions, suppression and containment are equally valid alternatives. It is not generally practicable to produce plant capable of withstanding such pressures unless it is of small volume and simple circular or spherical shape. Hammer mills and certain other grinding equipment is, however, often strong enough to contain an explosion. However, the design should consider any associated equipment (such as ducting or pipework) to ensure that it is of similar strength. E3.2 Summary In this section we have covered: Appropriate control measures to minimise fire and explosion risks • Control of sources of ignition • Control of sources of fuel • Control of sources of oxygen • Safe systems of work; safe-operating procedures; planned preventive maintenance programmes; management of contractors (in relation to fire safety); permits-to-work for 'hot work'; provision of information and training to workers and others; maintaining fire protection systems during maintenance; construction work on an existing building
• Actions to minimise risks from arson • The principles of preventing explosions • The methods for mitigating the consequences of explosions
