Safety & Health

+
Safety and Tolerability
  • Operating Personnel should be grounded by wearing static dissipative type I footwear.Wetting floors in the immediate operating areas with water before handling the hydroquinone may increase the dissipation of static charge accumulation.
  • Discharging hydroquinone from drums and supersacks can create significant static charge accumulation in the dry powder and should be done slowly. A good fugitive dust collection system is highly recommended to reduce the potential for personnel exposure during loading operation.
  • An inert gas atmosphere should be maintained at all times within any vessel into which hydroquinone is charged.The introduction of the dry powder can be the source for static discharge and ignition. When charging hydroquinone into inerted vessel,it is recommended that the oxygen content of vessel be monitored frequently since oxygen rich atmosphere can be created inside the vessel with the introduction of oxygen via the solid void space.
  • Minimize distances hydroquinone powder must free-fall in processing equipment.
  • Vessels and processing equipments should be electrically grounded.
