Due to the risks of the use and maintenance of hazardous materials, it is of utmost importance to distinguish between the laboratories and the areas where non-laboratory activities are carried out.
- Office areas should be planned separately from laboratories. The specialist and technician offices should be close to the laboratories.
- • There should be different areas from the wet work benches to record and take notes in laboratories.
- When planning laboratory workbenches, the areas required for chemical storage cabinets, fume cupboards, laminar flow cabinets, biosafety cabinets, refrigerators and freezers should be considered.
- The ventilation ducts for the fume hood should not be forgotten.
- • The ceiling height should be at least 300 cm. This height should be increased if there are ventilation ducts hanging from the ceiling.
- The windows should be 30 cm high from the workbench.
- • Aisle width should be at least 150 cm.
- For each person who will work in the laboratory, at least 150 cm laboratory equipment should be provided.
- • center for the purpose of washing the glass material forming the washing space are preferred. The depth of the washbasins and the height of the taps should be sufficient.
- It is important to place the central heating elements in such a way that they do not remain under the bench, if the laboratory is to be heated by heating system instead of heated air.
- Laboratory Bench Surfaces
- The material used in the laboratory floor must have a high chemical resistance and should consist of as few parts as possible. The parts where the floor joins the walls should be concave.
- • Floor material should be raised 100 cm on the wall. This height should be 150 cm in areas where the substance is stored.
- The floor should not be inclined to ground drainage channels. This prevents hazardous liquid chemicals from entering the drainage channel.
Walls and ceiling
- The walls should be non-porous and ideally painted with high gloss paint.
- Laboratories should be painted with light colors to reflect light.
- Lamps should ideally be at the same level as the ceiling, avoiding suspended lamps and hanging pipe systems in the laboratory (for ventilation or fume hoods).
- Laboratory Bench surfaces should be made of materials with high chemical resistance and no chemical substances.
- • Laboratory Bench surfaces should consist of as few pieces as possible. Materials such as tiles should not be preferred on bench surfaces.
- The edges of the workbench surfaces should be slightly raised to prevent the spilled liquid flowing on the wet workbench.
- Laboratory Bench depth should be 75-90 cm, height 90 cm.
- Laboratory Laboratory furniture should not be manufactured from materials with poor water and chemical resistance.
- The height between the under-counter cabinets and the floor must be sufficient for effective cleaning.
- It is important that the workbench or at least the underbench cabinets are of a portable nature and are necessary for the flexibility of the layout.
- There must be wash basins close to the outlet in the laboratory. In laboratories where microbiology and similar studies are carried out, taps should preferably not be opened manually.
- Laboratories must have an emergency exit door.
- Laboratory doors should be over 100 cm wide and should be self-closing.
- • There must be a glass window to prevent collisions in the laboratory doors.
- Laboratory doors should be opened outwards.
- There should be no equipment and laboratory bench to prevent entry and exit near the laboratory door and emergency exit door.
- Place a space for clothes hangers in an area close to the door.
- Security stations should be established in accessible corridors. These stations must have fire extinguishers, emergency showers, eye showers and kits for chemical and biological material spills.
- Emergency showers and eye showers should be within 10 seconds of any point of exposure to chemical-biological material exposure.
- Electrical outlets should not be closer than 50 cm to emergency showers, eye showers and washbasins.
- Must have smoke and fire alarm system.
- • Gas cylinders must be fixed to the wall with a chain.
- Tubes with compressed gas should be away from heat sources.
- • In the case of gas cylinders enclosed in enclosed spaces, these areas should be ventilated. There should be an effective ventilation system in enclosed spaces where tubes containing incompatible gases are combined.
- • There should be a gas detector near the tubes containing very toxic and flammable gases.
