1 Health and Safety Executive R COSHH essentials: Supplementary advice RPE with a UK Standard Assigned Protection Factor 10 (APF10) Control approach R Respiratory protective equipment (RPE) The Control of Substances Hazardous to Health Regulations 2002 (COSHH) require employers to ensure that exposure is prevented or, where this is not reasonably practicable, adequately controlled. This guidance gives practical advice on how this can be achieved by applying the principles of good practice for the control of exposure to substances hazardous to health, as required by COSHH. It is aimed at people whose responsibilities include the management of substances hazardous to health at work (eg occupational health specialists, anyone undertaking COSHH assessments, supervisors and is also useful for trade union and employee safety representatives). It will help you carry out COSHH assessments, review existing assessments, deliver training and supervise activities involving substances hazardous to health. This guidance is issued by the Health and Safety Executive. Following the guidance is not compulsory, unless specifically stated, and you are free to take other action. But if you do follow the guidance you will normally be doing enough to comply with the law. Health and safety inspectors seek to secure compliance with the law and may refer to this guidance. See Essential information near the end of the sheet. What this sheet covers This sheet describes good practice when using RPE with a UK Standard Assigned Protection Factor of 10 (APF 10). Main points This sheet gives some brief information on use and maintenance of RPE. You will have taken the decision that an APF of 10 or higher is adequate it is right for the hazard and reduces exposure to the level required to protect the wearer s health. This sheet helps you provide information to suppliers to identify respirators and breathing apparatus suitable for the wearer, task and the environment. Types of respirators available with an APF of 10: Disposable half-mask respirators. Classification FFP2. Reusable half-mask respirators particle filter. Classification half mask + P2 filter.

Classification 1B; Constant flow airline breathing apparatus with full suit. Classification 1A; Powered respirators with mask. Classification TM1; Powered respirators with hood/helmet. Classification TH1.

2 When RPE should be used 3 Use RPE: where an inhalation exposure risk remains after you have put in place other reasonable controls (residual risk); while you are putting in place other control measures (interim measures); for emergency work or temporary failure of controls where other means of control are not reasonably practicable; or for short-term or infrequent exposure, such as during maintenance work, where you decide that other controls at the source of the exposure are not reasonably practicable. Caution: Respirators must not be used in oxygen-deficient atmospheres as they can not replace the oxygen. You will require suitable breathing apparatus and should seek professional advice. Only those with appropriate training should use this type of breathing apparatus. Selecting the right RPE 3 The two main types of RPE are respirators and breathing apparatus. 3 Respirators (filtering devices) use filters to remove contaminants from the air being breathed in. They can be either: non-powered respirators relying on the wearer s breathing to draw air through the filter; or powered respirators using a motor to pass air through the filter to give a supply of clean air. 3 Remember that airborne liquids in the form of fine sprays and mists and solid materials, including dusts, fibres, smoke and fume, require a filter. The filter material will be different depending on the hazardous substance and its form. There are two basic filter types available: particle filters; gas/vapour filters. 3 Breathing apparatus (this is commonly referred to as BA) needs a supply of breathing-quality air from an independant source. Selecting RPE that is suitable 3 Ensure the RPE is adequate to control the hazards. Ensure it is suitable for: the individual wearer; the tasks they are doing; the environment in which they are working. 3 Involve the wearer in selecting the RPE. 3 Give wearers a choice of several adequate and suitable RPE so they can choose the one they find most comfortable. 3 This promotes compliance with wearing instructions. 3 Allow wearers to take a break if RPE is used for longer than one hour. 3 Where RPE is required to be worn continuously for long periods, powered respirators or airline Breathing Apparatus, for example a loose-fitting face piece such as a hood or helmet, is a better option. 3 Other common factors about the wearer you need to consider are: Check facial hair or markings don t prevent a good seal between the wearer s face and the RPE. Check pre-existing medical conditions. Ensure spectacles or contact lenses are compatible with RPE.

3 3 Ensure workers are medically fit to wear the required RPE (examples include breathing disorders such as asthma, skin allergies, or even heart problems). 3 For the task consider: work-rate; wear-time; vision requirements. Carrying out a fit test 3 For RPE with a tight-fitting facepiece, ensure each wearer undergoes a fit test. 3 Ensure fit testing is repeated on a regular basis Management and supervision 3 Ensure those wearing RPE follow the measures you put in place. 3 Make sure RPE is used where appropriate. Training 3 Train all people involved in the selection, use, storage and maintenance (if required) of RPE. An appropriate training programme should cover the following areas: Why RPE is needed; The hazards, risks and effects of exposure; What RPE is being provided; How RPE works; Why fit testing is required (if relevant); How to wear and check the RPE correctly; Fit checking before each use (see manufacturers instructions); What maintenance is required and when; Frequency of filter changing; Where and how it should be cleaned and stored; How to report/tackle any problems; Employee and employer responsibilities; Use and misuse of RPE; and Tell workers to discard disposable RPE at the end of the shift, or sooner if their RPE becomes blocked with dust. Maintenance 3 Use properly trained personnel to maintain all RPE that requires maintenance. 3 A thorough maintenance, examination and test should be carried out at least once a month. However, if the RPE is used only occasionally, an examination and test should be carried out before use and, in any event, the interval should not exceed three months. 3 Keep records of all examinations and tests for at least 5 years. 3 Ensure air supplied to BA meets minimum quality requirements in line with the latest British Standard.
