What are display screen equipment (DSE)? DSE is a set of electronic devices that can be used to produce, transmit and receive images. The most common types of displays include cathode ray tubes (CRT), liquid crystal displays (LCDs) and plasma screens. Other forms of displays such as light emitting diode (LED) televisions or digital projectors may also fall under this category.
The Health and Safety (Display Screen Equipment) Regulations 1992 came into force on 1st April 1993. These regulations were updated in 2002 with amendments made in 2005 and 2010. They cover all aspects of design, manufacture, installation, use, maintenance and repair of display screen equipment including CRTs, LCDs and Plasma Screens.
Technically “Display screen equipment” means any alphanumeric or graphic display screen, regardless of the display process involved. It includes cathode ray tubes (CRT), liquid crystal displays (LCD), plasma screens, projection systems, television sets, computer monitors, video games consoles, mobile phones, personal digital assistants (PDAs), electronic books, e-readers, tablets, smart watches, wearable devices, virtual reality headsets, augmented reality glasses, head mounted displays, heads up displays.
Analysis of workstations
Every employer shall perform a suitable and sufficient analysis of those workstations which are used by employees for carrying out their duties in order to determine whether they comply with this section. The analysis may be performed at intervals not exceeding six months from the date on which it is required to be carried out.
Every employer shall ensure that any workstation first put into service on or after 1st January 1993 (regardless of who has provided it) may be used for it’s correct purpose.
The Health and Safety (Display Screen Equipment) Regulations apply to workers who use DSE daily, for continuous periods of an hour or more. We describe these workers as ‘DSE users’. The regulations don’t apply to workers who use DSE infrequently or only use it for a short time. These are described as ‘non-users’.
