It is industry recognised that biological safety is of the upmost importance when handling pathogenic microorganisms within a laboratory environment. In line with the World Health Organisation Biosafety Guidelines we have developed level 2 and 3 biosafety mobile laboratories which deliver on function, cost and quality.

To determine the correct level of laboratory usage a risk assessment must be carried out. The risk assessment will provide a suitable biosafety level based upon all factors of the microbiological pathogen in question.

Once the correct biosafety level has been determined standard operating procedures can be developed to ensure the safest possible conduct of work.

Our design process follows a base model system which is then customised to meet the needs of the customer. We have a pre-selected equipment list which is used to meet the functional objectives of the customers needs. 

 CSC Plate Provision 

Each container developed by GLSI must pass a technical requirement of the ‘International Convention for Safe Containers’ in order to be awarded a re-plate after modification. This is carried out on completion from the factory, whereby the modified ISO shipping container is given a CSC plate valid for 5 years. GLSI use an independent accredited inspector to carry out this service.

Any container used for international transport must have a valid safety approval plate or "CSC plate". CSC is the abbreviation for Container Safety Convention. A CSC plate is required on all ISO containers that are being used for Intermodal transport. The CSC plate acts as a container’s certificate of safety, and allows container depots, and international ports the assurance that a container is safe to be handled and transported whilst fully loaded.



Commissioning and Installation

The commissioning and acceptance criteria is defined early on at the project. The commissioning process provides the institution and the surrounding community with a greater degree of confidence that the structural, electrical, mechanical and plumbing systems, containment and decontamination systems, and security and alarm systems will operate as designed, to assure containment of any potentially dangerous microorganisms being worked with in a particular laboratory or animal facility.

We provide a commissioning agent who is independent of the architectural, engineering and construction team involved in the design and construction. The commissioning agent serves as an advocate for the institution client, involvement of the agent in the early programming phase of the project is essential.

BSL 2 & 3

Biocontainment Laboratories 


Laboratory certification is the systematic examination of all safety features and processes within the laboratory (engineering controls, personal protective equipment and administrative controls). Biosafety practices and procedures are also examined.

Laboratory certification is an on-going quality and safety assurance activity that should take place on a regular basis. GLSI do not provide certification for a BSL level 2 & 3 facility as this is a process of continued accreditation through an external auditing body and the responsibility of the institution.

We can of course work with you to ensure the laboratory meets the requirements needed.
