EASURES
The following protection measures for avoiding eye damage should apply when the
µSPEED measuring unit is operating:
1. The measuring unit should be solidly fastened before operating it. It is necessary to
ensure that the laser beam does not freely propagate through the area by the use of the
laser tube and in addition by placing a laser blocking device (as shown in chapter 4.3)
e.g. an opaque plate with diffuse reflection.
2. If the measuring unit is not fastened, the unit has to be switched off. If this is not
possible the mechanical shutter has to be closed as shown in chapter 4.5.
3. The 10 cm area around the beam axis is to be signalled as a laser area. In the laser
area, the threshold for direct eye irradiation is exceeded. It is therefore necessary to
prevent anybody from manipulating plane reflecting surfaces or optical instruments in
the laser area. The laser area ends either where the beam is blocked by a target with
diffuse reflection or – when there is no such target – at a distance of 20 m.
4. A person responsible for laser protection should be charged in writing to
supervise the operation of the laser equipment.
5. The employer’s liability insurance association or the equivalent organization should
be informed prior to commissioning of the µSPEED that equipment including a laser
of class 3B will be operated.
6. The exact regulations can be found in BGV B2.
