The area in which the laser is used should be defined as a laser controlled area and access to this area should be limited to personnel whose presence at the operation is essential. Ideally the dors of the laser controlled area should be latched shut by a remote interlock which comes into operation when laser is switched on; appropriate warning notices bearing the words, Danger— visible and invisible laser radiation—avoid eye or skin exposure to direct or scatter radiation-class IV laser product, must be displayed at all points of access to the area.
