Personal confinement

Confinement principles

The confinement of potentially dangerous sources as regards operators is assured by the principle of barriers. Depending on the level of risk, one or two barriers are present between the source of danger and the operator. The elements that compose a barrier can be: a surrounding wall, an oven, a closed system, a ventilated hood, or a sorbonne, a glove box, or personal protection equipment.

One or two principle barriers.


Different types of barriers.

These barriers must ensure that it is permanently impossible, in normal operation, that the operator has any contact with the source of danger. For employees other than the operators of the task that has a nanomaterials risk, protection can be ensured by setting up a work place dedicated to handling in order to limit co-activity.
