This assessment must be carried out by the relevant Department/Section Head (or their nominee) . This checklist will help identify hazards and enable subsequent Risk Assessments to be completed where hazards cannot be eliminated. [See Section 19.1 - 19.5]. See also Section 18.42 in Document 2 for requirements of autoclaves, pressurised systems etc. Room/Location: _________________ No. of employees involved: _________________________ Nature of Work: ____________________________________________________________________________ Assessed By: _____________________________________________ Date: ____________________________ 1.0TRAINING AND INFORMATIONYESNON/ARECOMMENDATIONS/ACTIONS1.1 1.2 1.3 1.4 1.5 1.6 Have staff/students received basic training in the use of pressurised equipment by a qualified member of staff? Is staff aware of all possible hazards arising from incorrect use of equipment? Are there written procedures in place for: Pressure experiments? Autoclaves? Emergencies? Are all operators undergoing training supervised at all times by a nominated person? Do operators wear appropriate personal protective equipment when opening the doors? Are all experiments involving vessels under pressure authorised by a senior member of dept. staff and dept. safety officer? 2.0HIGH PRESSURE SYSTEMSYESNON/ARECOMMENDATIONS/ACTIONS2.1 2.2 2.3 2.4 2.5 2.6Have all high-pressure vessels/apparatus been tested by an independent engineer/insurance surveyor? Is a register kept of such equipment, inspections and retest? Is the maximum safe working conditions clearly and indelibly marked on each vessel with an identifying number? Are such equipment listed as pressure vessels on the insurance policy? Are safety valves, etc. situated to minimise the risk of injury in operation? Is the vessel free from:- Corrosion? Distortion? Scale formation? Weakened or worn closures? Leaks?  2.0HIGH PRESSURE SYSTEMS (cont.)YesNoN/ARECOMMENDATIONS/ACTIONS2.7 2.8If the equipment is used for chemical reactions is it: In a room set-aside for the purpose? Isolated by a 'blast' cubicle? Remotely controlled? Is eye protection worn when glass apparatus is taken above atmospheric pressure? 3.0AUTOCLAVESYesNoN/ARECOMMENDATIONS/ACTIONS3.1 3.2 3.3 3.4 3.5 3.6 3.7 3.8 3.9 3.10 3.11 3.12Is the machine listed as a pressure vessel on the College insurance policy? Are these arrangements for periodical thorough examination by a suitably qualified person (this examination, usually by an engineer of the insurance company, is distinct from the inspection below)? Is a logbook kept accessible to those operating the machine, giving details of the results of inspections and remedial action taken? Does the log book for each autoclave list the following information: Pressure and temperature at which apparatus has been tested. Maximum permissible working pressure and temperature. Construction materials including lining. Available volume. Details of pressure relief equipment. All subsequent information of periodic tests. the nature of each reaction carried out (summary) and any faults that developed during use. Are arrangements made for regular, systematic inspection and maintenance by a person, such as a maintenance engineer, qualified to identify defects and assess their effect on the safety of the vessel? Are the manufacturer's operating instructions displayed and followed? Are all moving parts lubricated weekly with an specified grade of grease? Is a comprehensive check carried out every two months by the maintenance engineer, including swivelling locking stirrups or swing bolts, and conditions of flanges? Is a log book of such checks and of all remedial work carried out kept accessible to those operating the machine? Is the machine in good condition, free from corrosion, leaks, etc? Is the door seal free from wear? Are the locking nuts, swing bolts and flanges free from wear and damage? 3.0AUTOCLAVES (Cont.)YesNoN/ARECOMMENDATIONS/ACTIONS3.13 3.14 3.15 3.16 3.17 3.18 3.19 3.20 3.21 3.22 3.23 3.24 3.25 Is the chamber clean and free from foreign matter, residues, etc.? Is the locking part of the door similarly clean? Is a test cock or other equivalent device fitted to give an audible and/or visual indication of internal pressure? Is the pressure gauge (and temperature gauge if fitted) positioned so as to be clearly visible to the operator at the door? Where a test cock is fitted, is a pin or rod provided on a captive chain, to enable the operator to ensure that it is not blocked? Is a device fitted to the door permitting it to be opened only sufficiently to break the seal after use requiring further release before the door can be opened? If the door is fitted with locking bolts, i.e. not of the quick release type, is this device attached to the bolts opposite the hinges? Is it possible to open the door, or break the seal, when the machine is at pressure? If fluids are autoclaved, is a safe period of time allowed to elapse after the end of the cycle, to avoid the risks from boiling fluids or exploding bottles? Conventional Bolted Doors: Are all bolts secured when the machine is in use? Are bolts tightened in pairs, one on each side of the door? Quick Opening Doors: Is there an interlocking device fitted to the door ensuring that the machine cannot be operated unless the door is correctly closed? Does the interlock also prevent the door being unlocked unless the steam valve is shut?
