Rainbow Trays™ – Anaesthetic Drug Safety

Designed to aid in the reduction of medication errors in anaesthesia and improve patient safety.


Innovative anaesthetic drug safety trays

Designed to aid in the reduction of medication errors in anaesthesia and improve patient safety. Rainbow Trays™ are colour coded anaesthetic trays for use in operating theatres by anaesthetists supporting the colour coded critical care labelling system as adopted by the AAGBI and RCoA.

The trays provide a safe environment for the transportation, administration and storage of syringes and ampoules.

The objective of the Rainbow Trays™ is to deliver standardised storage of drugs using a tray system that incorporates logical progression integrated with the established international colour coding for critical care drug labelling, without interfering with or confining the normal working practices of individual anaesthetists.

Rainbow Trays™ have been designed with the collaboration of anaesthetists, pharmacists and healthcare workers in response to the demands of best practice, clinical governance and patient safety​.

Rainbow Trays™ are an innovative but simple product that will make a significant contribution to patient safety in all areas where anaesthesia is delivered.

Rainbow Trays™ comprise three separate trays; The Main Tray for routine drugs, The Local Tray for local anaesthetics needing to be kept separate from the routine drugs to avoid accidental use and The Emergency Tray for drugs only to be used in emergency situations.

This configuration enables the routine, local and emergency drugs to be clearly separated with the two smaller trays being situated beneath the main routine tray if desired.

Current Practice

Current practice for the transportation and storage of anaesthetic drugs prior to administration usually involves all the drugs being placed in a single non-compartmentalised tray made from either paper pulp or polypropylene. This means that drugs can be swapped or misplaced and the respective ampoule is not at hand for quick checking prior to administration.

How it works

Rainbow Trays deliver on four important issues:


  • Supports the ASTM critical care colour code labelling system
  • Standardises the logical progression of use from induction to reversal


  • Physical separation of all drug types to reduce the risk of syringe swaps
  • Complete segregation of emergency and local anaesthetics
  • Keeps relevant ampoule with syringe for effective double checking

Infection Control

  • Bacteriostatic material will not harbour any bacterial growth
  • No dispersal of harmful pulp fibres in operating area
  • Single use trays

Patient Safety

The AAGBI & RCoA critical care labelling system for anaesthetic drugs is internationally recognised as an ASTM standard. This means that any healthcare professional worldwide will instantly understand the Rainbow Tray™ system and be able to use the trays with virtually no instruction. They are simple and effective in design and fully support an established mode of practice

NEW – Tamper Evident Rainbow Tray

Tamper Evident is the new addition to the Rainbow Trays portfolio which has been developed to address the new challenges faced by anaesthetic departments to provide secure carriers for anaesthetic drugs that keep the drugs safe and free from interference whilst they may be left unattended.

The design has had to meet a number of needs and benefits from the standardisation, segregation and infection control benefits already provided by the Rainbow Trays to deliver the gold standard in patient safety for this type of product

It complies with the requirements of the CQC to provide a system to account for controlled substances within the anaesthetic department and is a valuable tool to all Accountable Officers who need to quality assure processes for managing controlled drugs in their organisation.
