Alignment,levelling,control and survey tasks conducted in relation to or directly associated with construction,reconstruction,renovation,alteration, demolition,maintenance or repairs to buildings, structures or infrastructure.
Some examples of projects which will typically be associated with such tasks are as follows:
(a) Buildings, towers, tunnels.
(b) Roads, railways, bridges, wharves, and other transport infrastructure works.
(c) Works for drainage or irrigation.
NOTE: Operations involving the use of high power lasers and laser products for industrial processing applications (e.g. cutting, welding, annealing, scribing) and not directly associated with alignment, levelling, control or survey tasks are excluded from this definition and do not come within the scope of this Standard (AS/NZS IEC 60825.14 is applicable to such exclusions).
Scenarios where the level of illumination is low enough to cause the pupil of the eye to dilate to more than 5 mm diameter. In general it corresponds to a light level of less than approximately 100 lux.
NOTE: Recommendations on lighting conditions for various industrial applications are given in AS/NZS 1680.2.4.
The visible light (400 to 700 nm) or invisible optical radiation emitted by a laser product.Generally, the laser output is highly directional (collimated) and of a single wavelength (or colour). In other contexts, the terms‘ electromagnetic radiation’, ‘ optical radiation’ or ‘laser radiation’ may be used.
Specular reflections are those arising from shiny, mirror-like surfaces such as polished metals or glass. A laser reflected from such surfaces largely retains the properties which make it hazardous. A diffuse reflection arises from matt, non-glossy surfaces, such as paper or untreated wood. In general terminology this phenomenon would not be described as ‘reflection’. A laser reflected (scattered) from a diffusing surface is not hazardous, except when the laser is Class 4.
In the context of this Standard, ‘laser beam’ refers to the visible or invisible laser output emerging from the device. The majority of low-powered lasers used in the construction industry emit a narrow collimated beam which is most often used as a visual guide or alignment reference, or to obtain distance measurements.AS 2397 pdf free download.
