Procurement and Inventory Management of Hazardous Materials in Laboratories



The NUS Laboratory Materials Management System (LMMS) was developed in 2016 to enhance the management of regulated chemicals. Introduced to laboratory-based departments in phases, the campus-wide implementation of the LMMS was completed in Q4 2018.

The LMMS serves as an electronic inventory management tool that provides a real-time overview of chemicals that are in possession by the respective laboratories. It also ensures that the regulated chemical stocks are within licensed quantities. LMMS is mobile-enabled and will allow authorised personnel to have quick access to inventory records in emergency response situations on mobile devices.

To provide a seamless integration of procurement with the inventory management system, the Laboratory Materials Purchase Requisition System (LMPRS) was introduced in 2019. Chemicals purchased through LMPRS are directly inventorised into the Principal Investigator’s account in LMMS.

With reference to Directive 1902: Requirements on Procurement and Inventory of Chemicals, all chemicals shall be procured using LMPRS. Procurement and inventory management modules for biologics and radioisotopes will be included in LMPRS and LMMS in the future.
