Health & Safety

Shell Diala Oil DX is unlikely to present any significant health or safety hazard when properly used in the recommended application, and good standards of industrial and personal hygiene are maintained.

For further guidance on Product Health & Safety refer to the appropriate Shell Product Safety Data Sheet.

Storage Precautions

The critical electrical properties of Shell Diala Oil DX is easily compromised by minute concentrations of contaminants.  Typically encountered contaminants include moisture, particulates, fibres and surfactants.  Therefore, it is imperative that electrical insulating oils be kept clean and dry.

It is strongly recommended that storage containers be dedicated for electrical service and include air-tight seals.  It is further recommended that electrical insulating oils be stored indoors in climate-controlled environments.
