This information will help offshore What this sheet covers dutyholders (owners, operators and This sheet describes good practice for selecting respiratory protective contractors) to comply with the Control equipment (RPE). of Substances Hazardous to Health Regulations 2002 (COSHH), as amended, to When to use RPE protect workers’ health. 3 RPE is not a substitute for engineering controls. It is uncomfortable to use, expensive in the longer run, and always fails to danger.

3 Any air supplied to breathing apparatus must be fit to breathe, free of oil, water and other contaminants, and checked regularly.

Using RPE 3 Wearers must be medically fit to wear RPE. 3 RPE users need: n initial and repeat fit testing for RPE masks; n the right type and size of RPE for them personally; n training to check the fit every time, to wear RPE correctly and to

recognise defects; n any necessary instruction in cleaning and maintenance;

n to guard against tangling or mis-connection of BA air lines.

3 RPE must be worn the whole time while in the contaminated area, until the wearer is in clean air. 3 If RPE depends on a face seal, the worker must be clean shaven. 3 Keep RPE clean and store it in a clean place. 3 Change respirator filters and valves as recommended by the manufacturer. 3 Depending on the hazards present, respirators may need a combination filter to cope with both dust and vapour.

Caution: For filtering RPE, make sure the correct filter is fitted. Vapour filters will not give adequate protection against dust, and vice-versa

Procedures 3 RPE mask wearers must be fit-tested and trained how to look after it. RPE that depends on face-fit is suitable for clean-shaven workers only. 3 Ensure RPE fits properly. Tell workers to check it is working properly before every use. 3 Change the filters on respirators regularly – your supplier should be able to advise you. 3 Tell workers to discard disposable RPE at the end of the shift, or sooner if heavily soiled. 3 Keep RPE clean and store it in a clean place. Maintenance, examination and testing 3 Examine and test RPE thoroughly at least monthly and infrequently used RPE at least three monthly. Replace worn parts. 3 Replace time-expired, worn or damaged parts including valves and face seals. 3 Keep a stock of replaceable parts. 3 Check the expiry dates on RPE and filters. 3 Check the air quality to BA at least once every three months. Make sure that compressors take in only clean air. 3 Keep records of all maintenanace checks undertaken. Training 3 Training covers: n wearing RPE effectively; n the limitations of RPE; n storing RPE correctly;
