on carpet and glides or braked castors on hard surfaces.
Some standing tasks may be carried out using a sit/stand chair, for example some process or inspection work. This means that workers can support themselves on the chair while still carrying out the standing task. If the job is primarily carried out while standing, but the nature of the work allows workers to sit from time to time, appropriate seating should be provided. This allows workers to vary their position between sitting and standing.

2.6              Lighting
Sufficient lighting must be provided, whether it is from a natural or artificial source, to allow safe movement around the workplace and to allow workers to perform their job without having to adopt awkward postures or strain their eyes to see.
The following factors should be taken into account:
    * the nature of the work activity
    * the nature of hazards and risks in the workplace
    * the work environment
    * illumination levels, including both natural and artificial light
    * the transition of natural light over the day
    * glare
    * contrast
    * reflections.
Additional lighting may be needed for some types of work or at places of particular risk (such as crossing points on traffic routes). Table 1 provides guidance on the recommended illumination levels for various types of tasks, activities or interiors.
Different lighting levels may be needed for different times of the day. Too much lighting can result in glare. Measures to prevent low or excessive levels of lighting, glare or reflection include:
    * providing additional lighting, such as a lamp on a movable arm
    * changing the position of existing lights
    * changing the location of the workstation
    * increasing or decreasing the number of lights
    * changing the type of lighting used e.g. from white light to blue light
    * changing the diffusers or reflectors on existing lights
    * using screens, visors, shields, hoods, curtains, blinds or external louvers to reduce reflections, shadows and glare.
Emergency lighting must be provided for the safe evacuation of people in the event of an emergency.
