Must be of a suitable material for the type of work to be carried out. Worktops must be chemically resistent for the types of chemicals that need to be used in the space. Materials such as Trespa offers good chemical resistence with a hard, flat surface to work on. Epoxy resin and laminated particleboard with upvc edging can also offer a good surface. Having a seam-free surface will prevent ingress of chemicals into any gaps. A few surface materials may be able to accept a range of uses. Some may resist certain acids or stains, but not others, while others may resist abrasion and cutting and suffer moderate staining or wear. Knowing what chemicals are to be used and what activities are to be carried out in the space will be needed to determined early to identify the most suitable worktop surface.
Sufficient benches and working space for the number of people to be working in the laboratory must be considered to enable a safe working environment. There should also be sufficient space for trolleys to move around.
Work surfaces may need to also take the load of equipment, processing and analytical machines. Machines that are particularly heavy should be identified early as these may warrant their own mobile or fixed machine stands to be built.
The workbenches must be set at a minimum height of 900mm unless there is a need for a height adjustable workbench to be introduced for accessibility reasons.
Any chairs or stools placed in the laboratory must be of impervious material and be of a suitable height to work safely.
