Users shall work to Diamond's SHE Policy, and applicable Procedures & Handbooks.
As part of its endeavour to be a leading-edge scientific research facility, the Board of Diamond Light Source Ltd (Diamond) considers the effective management of safety, health and environmental (SHE) matters to be of prime importance. As such, it undertakes to provide a safe, healthy and environmentally sound workplace.
The Chief Executive Officer (CEO) has overall responsibility for SHE and ensures that the Executive and the Board proactively considers and reviews SHE issues. Executive members and associated management and supervisory teams will determine and commit sufficient resources and effort within their functional area to achieve SHE obligations. This includes the appointment of competent persons and advisers.
Executive members are committed to ensuring cooperation and coordination across Diamond groups and expect management to actively lead this process within Diamond and with contractors, users, and other interested parties.
Diamond’s SHE management system is modelled on recognised standards and will be achieved by integration with its management processes. This includes a commitment to continuous improvement and the setting of objectives. Clear performance indicators will be monitored, together with suitable audit and review processes.
Compliance with relevant SHE legislation, codes of practice and guidance are regarded as the minimum standard to be achieved. Diamond is committed to injury and ill-health prevention, minimisation of pollution and resource usage and promotion of positive mental and physical wellbeing. This includes designing, managing and maintaining its premises, structures and equipment so as to minimise the SHE risks associated with their construction, maintenance, use and decommission.
Diamond actively consults employees on SHE matters and fully accepts its responsibilities to users, visitors, contractors and others affected by its activities. Diamond requires such persons to cooperate with implementing this policy, associated rules and procedures. Employees are expected to work safely and adhere to the letter and spirit of this policy and report any practices or conditions that pose risk to safety, health or the environment.
Users bringing radioactive samples to Diamond shall read and adhere to Procedure for Radioactive User Samples at Diamond
Users accessing the Active Materials Laboratory (AML) shall read and adhere to Local Rules for the Active Materials Laboratory.
Good laboratory practice (GLP) and good hygiene standards shall be adhered to in chemical labs at all times, including:
Hazardous Substances
All processes using or generating hazardous substances require a COSHH assessment prior to starting the work. For users, this can generally be covered in the experimental risk assessment and lab assessment forms.
Fire Prevention and Precautions
Heat Sources
Where furnaces are used, the following precautions must be taken:
Storage of Substances
Storage of hazardous or dangerous substances must be in accordance with the hazard classes and the compatibility of classes.
Lab Equipment General Considerations
Local Exhaust Ventilation
Fume Cupboard Working Practice
Fume cupboards provide ventilation and partial containment of substance risks. Risk and COSHH assessments will inform you of when a fume cupboard is required.
Before use
Chemical Spills
For hazardous spills (less than 1 litre) you should take the following action:
For larger spills (greater than 1 litre):
Security
Good laboratory practice (GLP) and hygiene standards shall be adhered to in biological labs at all times, including:
Biological Materials
All biological work must be risk assessed and approved by an appropriate person and Biological Safety Officer (BSO) before the work starts. For Users, this can generally be covered in the experimental risk assessment and lab assessment forms.
All biological material being transferred between laboratories must be carried within a secondary container. The outer container must be decontaminated before leaving the laboratory. Therefore, no gloves must be worn outside of the laboratories.
All vessels containing substances must be clearly labelled at all times with contents, date and owner. Where possible, plastic storage containers should be used in preference to glass ones.
Aerosol production should be minimised and where an aerosol risk has been assessed by risk assessment, all work with HG2 agents shall be carried out in a Microbiological Safety Cabinet (MSC)
Storage of Biological Material
All biological material must be stored such that their containment cannot be breached. The containers should be labelled, leak-proof and their outer surfaces cleaned and/or decontaminated.
Refrigerators and freezers in which biological materials are kept must be labelled with biohazard labels.
An up-to-date inventory shall be maintained. A list, with references to the location of hazardous biological material in fridges and freezers, should be held in the laboratory.
If moving or transporting biological material on site, adequate precautions must be taken to minimize the risk of leakage and spillage. If there is a requirement to transport hazardous materials to or from site, contact the local Health and Safety department.
Hazardous Substances
All processes using or generating hazardous substances require a COSHH assessment prior to starting the work. For Users, this can generally be covered in the experimental risk assessment and lab assessment forms.
Storage of hazardous or dangerous substances must be in accordance with the hazard classes and the compatibility of classes.
Lab Equipment General Considerations
Fire Prevention and Precautions
Heat Sources
Where furnaces are used, the following precautions must be taken:
Spillages
Small Spill of Biological Material (<500ml) Outside of a MSC
Large Spill of Biological Material (>500ml) Outside of a MSC
Biological Spills inside a MSC
Biological spillages in centrifuges and shaking incubators
Security
Human tissue samples ('"relevant material" i.e. material that consists of, or includes, human cells) are not permitted at Diamond unless they are covered by a UK Research Ethics Committee (REC) approval.
Ethical approvals obtained locally within the UK or outside the UK do not apply.
UK REC approval can take 6-8 weeks to obtain. Evidence of approval shall be provided three weeks to Diamond before a User visit.

IEC 62471 describes the degree of risk from potential optical radiation hazards to minimise the need for further control measures for risk management. The defined risk groups are Exempt Group (RG0) for no risk, Risk Group 1 (RG1) for low, Risk Group 2 (RG2) for medium and Risk Group 3 (RG3) for high risk. For more information, read the UV radiation safety guide (CEO-HP-PRC-0022).
Users shall follow the relevant lab standard risk assessment(s) for the type of experiment they are conducting at Diamond. Contact your Local Contact to discuss details.
