Principles Of Hospital Design And Equipment (Part 9) - Laboratory

Standards, per capita and introduction of different wards of the hospital

Engineer Sadegh Pourbakht, Project Manager of Espo

The following spaces are essential in the laboratory:
Input - Acceptance and Response - Waiting for space for patients - Blood sampling cabinets - Separate sanitary facilities for urine and feces sampling - Labeling space - Sample collection area - Clean work - Headroom - Spaces, halls Or laboratory rooms including independent room for microbiology, bacteriology, mycology, virology, environment, hematology, biochemistry, urinalysis, parasitology, immunology, pathology, cytology, etc. - Reporting room of the laboratory doctor-bank Blood, separate toilets for employees - support spaces such as staff rest and locker room, staff watering room, dirty and washing room and sterilization of containers, clean storage warehouse, consumer storage warehouse such as sampling containers, warehouse or laboratory equipment park, sliding storage space, Separate storage space between trash cans, refrigerators or refrigerators for storing medicine and laboratory materials, emergency shower and eyewash
The following spaces in the laboratory are recommended:
Independent Department of Pathology, Archive and Type Room, Pathologist's Room, Preparation Room, Tissue Storage, which should be located inside the Pass Room, Independent Laboratory for the Emergency Department, Distillation Water Room, Independent Sampling Laboratory, for easy collection and transfer of samples, disposal space or evacuation of samples
Laboratory infrastructure:
The best area of ​​medical diagnosis and pathology laboratories is 2% of the total hospital area. In any case, this area should not be less than 160 square meters.
The laboratory section should be designed in such a way that the process of patient admission, sampling, collection and sending of samples, conducting experiments, preparing reports, and responding to the patient is easily possible.
The minimum useful area of ​​the reception and response space in the laboratory section without taking into account the bathroom and the entrance space is 8 square meters.
At least the microbiology room should be closed and not cluttered with other laboratory spaces. The air pressure in this room is negative compared to other laboratory spaces.
Patients and laboratory staff should be able to access emergency exits, and these exits should be marked with clear signs.
Access to the laboratory and sampling for patients is easy. Also, the inter-sectoral relations between the laboratory department and other required hospital services such as emergency rooms, clinics, inpatient wards, facilities, elevators, etc. should be easily provided.

Sewage pipes in the laboratory should be made of polyethylene or polypropylene to prevent corrosion. Laboratory wastewater must enter the absorption well or wastewater treatment plant directly and without human intervention.
3-12-3-9 Hospitals over 240 beds or if the distance between the emergency department of the hospital and the central laboratory is more than 50 meters, it is necessary to have a laboratory with full facilities inside the emergency department.
3-12-3-10 It is recommended that the location of the laboratory department in the hospital be as far as possible up to the first floor due to the need for inter-sectoral communications, equipment, and special infrastructure.
To prevent the transmission of contamination to patients, the place of entry and exit, admission and sampling of patients should be separate and away from laboratory spaces such as microbiology.
Laboratory or sampling should never be used as a transit to access other departments.
The materials, accessories, and lighting used in the laboratory should be such that while creating a hygienic and washable space, they prevent the occurrence of audio, optical, and visual abnormalities.
Due to the nature of the laboratory section, it is necessary to change the air 6 to 10 times per hour for this section.
The air pressure in the main laboratory environment is negative compared to the corridor or common space of the laboratory. Similarly, the air pressure in the hallway or the common space of the laboratory section is negative compared to the spaces outside the laboratory.
Exhaust air passage or preparation room must be independent of other spaces in the pathology department.
The maximum allowable humidity in laboratory sections in different seasons of the year is 60%.
The design of the support spaces in the laboratory section should be by the current conditions of the section, the number of tests during the day and other available per capita, and should meet the needs of this section.
Due to the sensitivity and high cost of laboratory equipment, the electrical system of the laboratory should be equipped with UPS and protective equipment and supplies.
