PPE patent complete to comply Health and Safety Executive (HSE) standards for hearing protection in high-noise environments, such as factories and flight lines. Personal Protective Equipment (PPE) Directive adopted by the European Council in 1989 was superseded in April 2018 by a new PPE Regulation (EU)2016/425. The new regulation was created to enhance consumer safety and ensure fair competition between companies who provide PPE for their sector. Regulatory changes include moving Hearing Protection from Category II to Category III. This category exclusively includes the risk that harmful noise may cause very serious consequences such as irreversible damage to health. Health and Safety officers, from April 2018, must make sure that the hearing protection products used by employees comply with the Personal Protective Equipment (PPE) Regulation (EU)2016/425.
