What is ISO/TS 16976‑3 - Physiological responses and limitations of oxygen and carbon dioxide on respiratory protective devices (RPD) about ?
ISO/TS 16976‑3 discusses respiratory protective devices (RPD). ISO/TS 16976‑3 is an international standard that provides physiological responses and limitations of oxygen and carbon dioxide on RPD.
ISO/TS 16976‑3 is the third part of a multi-series that identify oxygen and carbon dioxide concentration limit values and the length of time within which they would not be expected to impose physiological distress.
ISO/TS 16976‑3 addresses both high-altitude exposures where low partial pressures are encountered and underwater diving, which involves conditions with high partial pressures.
ISO/TS 16976‑3 specifies:
- A description of the composition of the Earth's atmosphere, and physiology of human respiration
- A survey of the current biomedical literature on the effects of carbon dioxide and oxygen on human physiology
- Examples of environmental circumstances where the partial pressure of oxygen or carbon dioxide can vary from that found at sea level
Who is ISO/TS 16976‑3 - Physiological responses and limitations of oxygen and carbon dioxide on RPD for ?
ISO/TS 16976‑3 on physiological responses and limitations of oxygen and carbon dioxide on RPD is useful for:
- Entities who work in the dusty atmosphere
- Craftsperson who works with hazardous chemicals, particulates, vapors, and gases
- Manufacturers of Respiratory Protection Equipment
- Any entity working in mining, cement production
Why should you use ISO/TS 16976‑3- Physiological responses and limitations of oxygen and carbon dioxide on RPD ?
Respiratory Protective Devices (RPD) are used to protect the individual wearer against the inhalation of hazardous substances in the workplace air. Many of these devices protect against airborne contaminants without supplying air or other breathing gas mixtures to the user.
ISO/TS 16976‑3 deals with the impact of altered partial pressures/concentrations of oxygen and carbon dioxide on respirator use.
ISO/TS 16976‑3 serves as the basis for advancing research and development of RPD to minimize the changes in the breathing environment, thus minimizing the physiological impact of RPD use on the wearer, and ensuring health and safety of all workers recommended by their occupation to wear RPD.
What is changed since the last update ?
ISO/TS 16976‑3 is the second edition that cancels and replaces the first edition ISO/TS 16976‑3:2011. The main changes compared to the previous edition are:
- Explanation of the new limits for CO2 derived from a study
- Addition of a new Table 3 to give limits for CO2 when breathing against imposed breathing resistance
