The green equipment to the right is a silicon flask.
Coats, along with gloves and shoes, prevent contamination of workers' clothes.
It only takes a speck of dust, so protection is essential.
In the operational days of HIFAR, all protective equipment was be required to be worn under all circumstances when accessing the reactor.
Health physics surveyors were always present to monitor personnel health, ensure safe work conditions, and check staff for contamination when leaving the reactor work area.
Silicon Irradiation Handling Flask is part of the Lost Collective 'ANSTO HIFAR' series.
