Huawei has developed strict systems for product safety control, and enforced strict product safety standards. Our goal is to deliver safe, dependable products and services to customers and consumers. As part of this goal, we are committed to researching and innovating product safety technologies, and adopting best practices. Reducing electromagnetic radiation remains one of our focus areas, and we have increased our research into dermatological reactions. We have also
worked with leading international organizations on the issue of noise control, to ensure that our products conform to every noise standard. And we have adopted a user scenario-based approach to product safety design, thereby ensuring that our products are easy to install, easy to use, and meet all relevant health and safety standards.
Huawei has developed strict standards for controlling electromagnetic radiation levels. Our ongoing research and innovation helps to ensure that our products conform to all legal and technical standards. Base stations are becoming smaller, lighter, and are being installed closer to ground level. In response, we are building additional electromagnetic radiation protection into their design, and carrying out more research and testing. This allows us to deliver both excellent communications services and product safety. We have helped our customers to carry out many electromagnetic surveys of residential areas, and engaged with public concerns over electromagnetic radiation. The widespread adoption of smartphones has also brought forth new challenges in consumer safety. In addition to our base stations, Huawei products for consumers, homes, and enterprises all satisfy the relevant standards for electromagnetic radiation.
The explosion of new smart devices in recent years has brought consumers a rich range of new experiences, but has also created health and safety challenges. In non-ICT industries, there are existing standards for allergens, such as those for textiles and children’s toys, and EU directives for medical devices. However, in the communications industry, there is not yet a widespread understanding of the issue of allergic reactions, and dermatological worries are particularly acute for wearables and children’s products.
We are well aware of the potential risks to health posed by allergic reactions, and are managing the dermatological safety of our products. We have invested in research with the Japanese Dermatological Association and the Japan Medical Association Research Institute (JMARI), which is laying a solid foundation for reducing the risk of allergic reactions.
In 2015, we worked with the TÜV SÜD, SGS, and other specialist organizations to develop an allergen standard for smartphone accessories, referencing the standards already available for medical equipment, toys, and textiles. We also developed manufacturing control mechanisms, and established the Huawei Device Anti-allergen Team to set our internal standards for allergens and control processes. We aim to raise awareness of allergy issues within the communications industry, and are working with industry partners to draft standards. We are committed to minimizing the negative impact of communication products on human health and safety.
Huawei has a specialist ergonomic design team, which promotes safe product design based on real user scenarios. Ergonomic design is built into every phase of product planning, design, development, and testing, so that our products are adapted to users’ engineering habits and technical needs while reducing health and safety risks at the installation and usage stages.
As of the end of 2015, we had collected user scenarios in 25 countries and regions, including major telecom carriers across Europe, North America, Latin America, Africa, and Asia. We increased our focus on Africa, gaining deeper insight into local engineering delivery practices and user habits. With innovative designs based on real user scenarios, we have been able to deliver products that are easy to use, easy to install, and better meet ergonomic requirements.
Optimizing Ergonomic Design to Prevent Safety Risks
The Huawei Distributed Converged Cable Access Platform (D-CCAP) has been developed using the Data over Cable Service Interface Specification (DOCSIS) to integrate into FTTx systems, supporting simplified network roll-out and management. The solution reduces health and safety risks during installation and usage, and ensures a clearer, smoother audiovisual experience for Internet users. The solution has been implemented in 30 countries and regions around the world. Its excellent ergonomic design elements are as follows:
- Adaptable: The multifunctional installation brackets provide 100% support for installation on cables, in equipment cabinets, on exterior walls, or on simple poles. Such a high degree of adaptability avoids the need for network reconstruction.
- Pre-assembly: Units to be installed on cables can be pre-assembled, freeing up the hands of the installation engineer. Single engineer installation allows for faster rollout.
- Modular: One of the common problems faced by customers is that they cannot easily swap out single pieces of equipment, but must remove entire units. The modular design of the D-CCAP solution allows for the easy swapping of equipment by a single engineer, so that equipment can be maintained and upgraded without replacing entire cables.

As part of our commitment to ongoing improvements in product quality, we are always working to decrease product noise levels, thus minimizing our impact on the environment. We have carried out ongoing noise level surveys, and have made significant improvements in the design of many products. For example, at one data center, a noise survey and diagnostic analysis led us to design improvements into the ventilation pipes and sound baffles in the switches. As a result, noise was reduced by 6.5dB (A). We also redesigned the fan housing of a router to achieve a noise reduction of 6dB (A), with no reduction in cooling power.
We track the latest developments in noise reduction technology, and have close links with universities and research institutes working on noise control. The Huawei Environmental Acoustics Lab has long been ISO/IEC 17025 certified by both the American Association for Laboratory Accreditation (A2LA) and the China National Accreditation Service for Conformity Assessment (CNAS), and is recognized by major testing and certification organizations such as UL, MET Laboratories, and National Technical Systems (NTS). The lab supports our efforts to measure, locate, and control environmental noise with some of the world’s most advanced noise testing equipment.
