        make proper use of a wrist rest when using a mouse or a keyboard.

        make use of anti-glare screens if lighting in the room is incorrect; or use window blinds to reduce sunlight reflecting from the screen
        
        take regular breaks (and try focusing on a point that is some distance away)
        
        change to LCD screens where flicker is less of a problem than with CRT screens
        
        ensure that there is no screen flicker as this can lead to eye problems
    - - proper ventilation should exist to remove the ozone gas as quickly as possible
        
        laser printers should be housed in a designated printer room
        
        change to other types of printer if necessary (e g, inkjet printers)

        don't cover equipment vents (causing equipment to overheat). make sure that the electrics used in the hardware is fully maintained (i.e. portable appliance testing)
        
        ensure good ventilation in the room (again to stop overheating of hardware)
        
        don't overload sockets with too many items
        
        change to low-voltage hardware wherever possible (e.9., replace CRT monitors with LCD monitors)
    - - use cable ducts to make the wires safe
        
        cover wires and/or have them neatly tucked away (under desks, etc.)
        
        use wireless connections wherever possible, thus eliminating cables altogether
