Page 4 of 37 Compressed Gas Cylinders and Systems: Health & Safety Policy, Procedures and Guidance for QMUL 1. Executive Summary This Health and Safety Policy establishes the framework for the effective risk management of work with compressed gas cylinders and associated systems by Queen Mary University of London (QMUL) staff, students and others who may be affected by QMUL activities. The Policy defines the requirements for safe management of compressed gas cylinders and systems in the context of QMUL’s activities: This includes the design and installation of compressed gas systems and facilities identifies the roles and responsibilities for Heads / Managers / Supervisors of Schools / Institutes / Directorates responsible for the work and systems the roles of QMUL staff, students and others who conduct or may be affected by the work, Notes the key legal and compliance requirements specified in the relevant health and safety legislation and supporting guidance. Topic guidance, practical information and template procedures are also provided for QMUL. This version of the Policy has been issued following QMUL wide consultation and approval by the QMUL Health & Safety Advisory Group on 08 Oct 2018. PART A: Policy 2. Policy Objective and Statement 2.1 The Policy Objective of Queen Mary University of London (QMUL) is to control and reduce the level of risk from work with compressed gas cylinders and associated systems (pipework and connected equipment) to a tolerable level, and where significant risk is foreseeable, to eliminate the risk/s, and to ensure compliance with the legislation applicable to the work activities and equipment. 2.2 It is the QMUL Statement of Policy that risk assessment/s for work with compressed gas systems and cylinders are conducted before commencing the work and are continuously reviewed and updated in line with work and technology changes, upon an incident and other significant variables. This includes design risk assessments for new and refurbished installations and facilities for compressed gas systems and cylinders. The effective risk control measures identified shall be implemented and maintained throughout the duration of the work until removal of the risks. 3. Applicable Legislation 3.1 Although there is no single ‘topic specific’ H&S regulation concerning compressed gas systems and cylinders, there are a number of statutory instruments that are, in addition to the general provisions of Health & Safety at Work Act etc 1974, relevant to the safe management of compressed gas systems and cylinders: QMUL/HS/113 H&S Policy Procedures and Guidance Compressed Gas Systems and Cylinders Jan 2020

Page 5 of 37 3.2 The Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) along with the Regulatory Reform (Fire Safety) Order 2005 (FSO 2005) require risk assessments to address the management and effective control of hazardous substances and flammable atmosphere conditions (including those from compressed gases) that can cause fires and explosions; 3.3 The Pressure Systems Safety Regulations (PSSR) 2000 apply when a pressure system contains or is likely to contain a relevant fluid (e.g. compressed gas, steam) over with a pressure x volume product of 250 bar litres during normal use and/or if a failure occurs. The requirements under PSSR include a Written Scheme of Examination (WSE), recorded specific equipment testing (thorough examination), safe operating procedures and a recorded maintenance regime. 3.4 The Provision and Use of Work Equipment Regulations 1998 requires that all work equipment is safe for the intended use, is maintained for safe use and is regularly inspected, is used by those who have received the appropriate training and has appropriate safety controls such as emergency stop devices, means of isolating form electrical or other energy sources and hazard warning signs. 3.5 Where toxic or asphyxiate gases are used, The Control of Substances Hazardous to Health (COSHH) Regulations 2002 (as amended) requires the effective containment of the gas and to eliminate exposure to toxic gases and remove asphyxiating conditions where risks to human health may exist or be foreseeable (or reduce to a level where harm to health cannot occur). 3.6 The Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009 are concerned with handling and transporting hazardous materials including compressed gas cylinders. Where QMUL employees handle and transport compressed gas cylinders, the duties to ensure safe transport and compliance with regulations (in particular when on public highways) will reside with QMUL. 3.7 If other risks are involved with the use of compressed gas systems and cylinders (e.g. manual handling, unsafe confined spaces), prior risk assessment should also identify the level of risk and identify risk controls to eliminate or reduce risk to levels where harm is reduced to negligible levels. 3.8 There are also regulations applicable for those who design and manufacture pressure equipment and assembling of pressure equipment to ensure safe design and build for use. Where QMUL aim to sell or transfer a pressurised system to another organisation or Institution, the requirements of these regulations would apply. 4. Application and Scope of the Policy 4.1 This Policy applies to all QMUL staff, postgraduate and undergraduate students and others (e.g. contractors) who are to design, install, use, decommission and dispose of compressed gas cylinders and associated systems for QMUL activities. 4.2 This Policy document does not deal with the following aspects which are addressed in separate QMUL or external documents: QMUL/HS/113 H&S Policy Procedures and Guidance Compressed Gas Systems and Cylinders Jan 2020

Page 6 of 37 4.2.1 Thermal hazards and risks of cryogenic liquids and solids – refer to QMUL policy and guidance at http://www.hsd.qmul.ac.uk/a-z/cryogenicliquids/. 4.2.2 Specialist fire protective measures – refer to QMUL policy, procedures and guidance at http://www.hsd.qmul.ac.uk/a-z/fire-safety/ 4.2.3 QMUL Local Arrangements and Procedures for Compressed Gas Systems and Cylinders: Where the compressed gas facilities are managed by Estates & Facilities, the Estates Management & Arrangements Procedure (EMAP) documents at http://qm-web.estates.qmul.ac.uk/hs/ detail these - particularly applicable for compressed gas systems are EMAPs 31 and 51. QMUL School Institutes and Directorates local arrangements and procedure documents must comply with the QMUL H&S policy and as applicable, with the EMAP documents. 4.2.4 Compressed gas cylinders used in adverse or extreme conditions, such as for breathing apparatus, may require special precautions. Although this policy is valid for normal uses of compressed gas cylinders, special precautions such as different frequencies for periodic inspections, are not covered and specific risk assessments and procedures must be in place prior to such activities commencing. 4.2.4 Detailed technical information on compressed gas cylinders and systems including physical / chemical properties and hazards of gases – these are obtainable from the national industry body, the British Compressed Gas Association (BCGA) documents at http://www.bcga.co.uk/pages/index.cfm. 5. Definitions 5.1 Compressed Gas: a non-flammable material or mixture having in the container a pressure exceeding 41 psia (absolute) (3 bar) at 70 F (21 C), or any flammable or toxic material that is a gas at 70 F (21 C) and has a pressure of 14.7 psia (1 bar) or greater. Most compressed gases will not exceed 2,000 to 2,640 psig (gauge) (138 to 182 bar), though some may go up to 6,000 psig (414 bar). Non-liquefied Compressed Gas: Chemical or material, other than gas in solution, that under the charged pressure is entirely gaseous at a temperature of 70 F (21 C). Liquefied Compressed Gas: Chemical or material that, under the charged pressure, is partially liquid at a temperature of 70 F (21 C). Gas Cylinder: a pressure receptacle or vessel, which includes a cryogenic receptacle, bundle of cylinders as well as cylinders themselves, plus the valve(s) or regulator fitted directly to the receptacle. Written Scheme of Examination (WSE): a document containing information about selected items of plant or equipment which form a pressure system which operate under pressure and contain a ‘relevant fluid’. Relevant Fluid: A ‘relevant fluid’ is defined as compressed or liquefied gas, including air, at a pressure greater than 0.5 bar (approximately 7 psi) above atmospheric pressure; pressurised hot water above 110 C; and steam at any pressure. 5.2: 5.3 5.4 5.5 5.6 6. Risk Assessment 6.1 Heads of Schools, Institutes or Directorates must establish procedures for assessing the hazards and risks associated with compressed gas systems and cylinders within their control at QMUL. 6.2 Compressed gas cylinders and associated systems are used widely across QMUL including in QMUL/HS/113 H&S Policy Procedures and Guidance Compressed Gas Systems and Cylinders Jan 2020

Page 7 of 37 6.3 Laboratory chemical and other experiments and workshop processes Soldering, welding and flame cutting for workshop, maintenance and construction activities Breathing apparatus (e.g. for diving, emergency rescue) Medical (patient or first aid treatment, e.g. with medical oxygen) and laboratory uses (e.g. for operation of experimental instruments and equipment) Dispensing beverages in catering outlets Fuel containers for vehicles (e.g. fork-lift trucks) Equipment for extinguishing fires Domestic and commercial heating and cooking Water treatment systems and devices The main hazards from compressed gas cylinders and systems are 6.4 Impact from the blast of a gas cylinder explosion or rapid release of compressed gas Impact from parts of gas cylinders or valves that fail, or any flying debris Contact with the released gas or fluid (e.g. chlorine, hot steam) and possible injection into the blood stream and acute toxic or other health hazard effects and/or acute / chronic damage to organs of the body Asphyxiation from the release of inert (e.g. argon) or oxygen depleting gases (e.g. gas evolving from liquefied nitrogen) in confined or semi-confined conditions Fire and creation of flammable atmospheres resulting from the escape of flammable gases or fluids (e.g. liquefied petroleum gas) Impact from falling cylinders Manual handling injuries from unsafe handling and transport of cylinders. Location Risk Controls 1. Due to the increased dangers, in the event of fire, associated with the use of standalone compressed gas cylinders located in buildings, the preferred method of providing compressed gases within QMUL buildings is via maintained piped systems attached to gas cylinders in secure, safe and well ventilated locations outside the building. 2. 3. Where this is not possible, For new buildings or major refurbishments this must be taken into account during the design stage by, for example, locating those rooms/laboratories requiring piped gas on the lower floors wherever possible. For new and existing buildings, gas cylinders can be located within buildings in purpose-built fire-resistant enclosures (with a minimum of 30 minute rated fire protection – see /QMUL HS 060 August -2012 Fire-Resisting-Cabinets-Technical-Standard.docx ). See circumstances where greater fire rated protection (e.g. 60 min or 90 min) may be required in sections 3 and 4. The following risk minimisation controls must also be considered and implemented where assessed as required: locating of cylinders away from escape routes QMUL/HS/113 H&S Policy Procedures and Guidance Compressed Gas Systems and Cylinders Jan 2020

Page 8 of 37 Flammable gases, such as hydrogen, sited away from sources of ignition and oxidising substances. Installation of sprinkler systems and/or fire damping or suppression systems although these can be difficult to retro-fit in existing buildings. Storage of reserve gas cylinders within buildings should be limited in favour of a rapid cylinder replacement service as far as practicable. Gas cylinders can often be replaced by gas generation systems. 4. Management Options for deciding on safest location: a risk based approach to the management of compressed gases combined with a hierarchy of management options for the supply of gas for laboratories and workshops at QMUL can be broadly expressed as follows: Gases generated in situ using propriety gas generators. Gas cylinders located outside of buildings in secure well-ventilated storage areas with gas piped to the areas of use. Gas cylinders stored outside of buildings and brought into the building only when needed. Further ‘in use’ and procedural risk controls are detailed in Appendix 1. 7. Roles and Responsibilities 7.1 QMUL Head of School or Directorate / Director of Institute It is the responsibility* of the Head of School / Directorate or Institute Director to ensure that; 1. Staff with supervisory and allocated health & safety responsibilities are appointed, trained and are competent for the work involving compressed gas systems and cylinders (e.g. responsible technical, laboratory officer or manager). 2. A framework for the School / Directorate / Institute is in place for the drafting, dissemination, implementation and review of risk assessment/s and local procedures (‘safe systems of work’) for work involving compressed gas systems and cylinders and for the involved facilities / infrastructure, in line with QMUL policy, arrangements and guidance. 3. Notification to HSD in advance of any installation and use of significantly higher risk compressed gases and systems such as flammable and toxic gas compressed gas systems so that appropriate advice can be given. QMUL planning processes already in place should be utilised – e.g. the QMUL Project Board system, the QMUL Long Term Maintenance planning system.
