Zone 1 Grille Shutter - Explosion proof motor.
GlaxoSmithKline is a well-known worldwide pharmaceutical
company.
Drathmore had the task of installing a shutter grille with
the added feature of being suitable for use in a hazardous
area (requiring specialised equipment). From the motor to
the simple 3 button push switch, all components had to be
suitable for ‘Zone 1 area’ (flammable atmosphere
possible but unlikely to be present for long periods, see
below), due to the type of chemicals that would be stored
in the bay.
Hazardous areas are defined by three main criteria:
• The type of hazard
• The likelihood of the hazard being present in flammable
concentrations.
• The (auto) ignition temperature of the hazardous material.
Job completed November 2008.
