In most cases these will involve the transfer of liquids or gases from containers or processes to other operations. These tasks may require a variety of physical properties like mechanical strength, durability, resistance to wear and tear or good chemical resistance or both. In all cases the selection of the tubing must match the requirements of the task in hand e.g. should it be reinforced and coloured, when handling high-pressure hazardous gases or liquids etc.? 18.25.2 HAZARDS Defective tubing or defective securing of tubing to nipples/taps can result in the sudden release of gas or liquid, possible with ignition and fire, or explosion. Hot liquids or mains water under pressure may also be released. Injury and property damage may range from minor to severe. 18.25.3 RISKS The risks associated with the aforementioned hazards are to be assessed by the Department (using the appropriate technical input where necessary). These assessments shall be carried out using: (I) Check lists provided (where applicable) and (ii) Departmental Hazard Identification/Risk Assessment Work Sheets contained in Document No.3 i.e. Departmental Hazard & Risk Assessment (D.H.R.A.). 18.25.4 ARRANGEMENTS AND CONTROLS REQUIRED These hazards and risks will be minimised by the following arrangements and controls: All rubber and plastic tubing should be checked periodically for cracks or other damage, prior to use. Replacement must be made promptly where necessary Rubber tubing should not be used on permanent installations connected to laboratory services. Clear Neoprene plastic tubing should be utilised. Excessive lengths of tubing which may lose their identity or which may trail and pose tripping hazards or which may trail into hot/corrosive areas should not be used Tubing for use with organic solvents must be chosen carefully. The suitability of material must be checked for each solvent. Tubes to filter pumps and cooling circuits must be secured by a jubilee clip fitting. The tube carrying the outflow should be firmly anchored in the drain and free from danger of kinking 18.25.5 ARRANGEMENTS AND CONTROLS The details of the Arrangements and Controls in place and those required in the short, medium and long term, shall be set out by the Department in the forms provided in Document No.4 i.e. Departmental Safety Action Plan (D.S.A.P.). These Arrangements and Controls shall be reviewed and updated on a yearly basis. 18.25.6 RESPONSIBILITIES The following personnel are responsible in the Department/Lab/Area for ensuring the implementation and ongoing compliance with the aforementioned arrangements and controls.
