■ Storing gaskets
Store gaskets in a clean, cool and dark room. If they are stored in a place where they are exposed to direct sunlight, ozone, high tempera- ture, high humidity, or a corrosive environment, the materials of the gaskets will deteriorate.
Store gaskets horizontally on shelves, leaving them packed in order to prevent lodgment of dirt, and so on. Also, place a cushioning sheet between the gaskets.
Do not suspend a gasket from a hook, or store it with a heavy object placed on it, because this may cause the gasket to break.
■ Handling gaskets
When handling a gasket, avoid the following behavior because this will lead to deformation or deterioration of the sealing per- formance.
・ Do not throw a gasket, tread on it, pull it, bend it, fold it, rub two gas- kets together, hold a large diam- eter gasket in one hand, or shake a gasket while holding it.
■ Disposing of gaskets
Dispose of used gaskets and scraps generated by shaping them in a dedicated disposal container and store and dispose of them separately from other items.
When disposing of such items, observe the related laws and regulations in your area. Do not incinerate these items. Note, however, that they can be incin- erated using incinerating facili- ties that have suitable treatment equipment.
