Background
In this test, we want to:• Examine how to provide effective protection using various
types of PPE– Gloves
– Suits
• Compare the protection efficiency of two very different protective suits
• Explore the importance of pressurisation
• Identify the issues associated with decontamination & safe removal of contaminated PPE

A Word on PPE
• High standard of protection expected
• Simple to use
• Recognise limitations
• Training to match hazards
• Last line of defence
• Sometimes PPE is only option

Important:
This is not a scientific experiment — rather an informal way of exploring some basic aspects of personal protection equipment against hazardous substances

• Glows under UV light
• Dispensed as aerosol from 4 nozzles inside the tent

The test begins
A white inner suit is used for easy detection of any contaminant leaking through outer suit

How pressurisation works
• When user does not need air (e.g. when breathing out), clean air is channelled into the suit instead of the respirator
• The suit inflates at every exhalation
• A slight positive pressure is maintained within the suit at all times
