Risk remaining after the higher controls is minimised so far as reasonably practicable with suitable PPE, provided at no cost to workers and suitable for the worker (size and fit), the work and the work environment, and meeting any relevant Australian Standard. PPE only protects if workers wear suitable equipment and use it correctly, so the PCBU should have policies and procedures on correct use, maintenance, cleaning or disposal and storage; train workers in correct use including when to use PPE and how to remove and clean or dispose of contaminated items safely; select PPE that is right for the biological hazard and the type and level of exposure, for example respirators with a suitable protection factor for organic dust; fit test tight-fitting respirators before first use for fit and comfort; check PPE regularly for condition, faults, cleaning and storage; and confirm it is used correctly. Where several types of PPE are worn together they must not compromise each other, for instance goggles must not break the seal of a face mask, and workers must follow procedures to wear PPE correctly. Suitable items include face shields and eye protection against splashes and sprays, long sleeves against plant contact, repellent against mosquito bites, and properly fitted respiratory protection against inhaling small particles carrying airborne hazards; detailed guidance sits in Appendix G.
