In order to better fulfil customer requirements, improve the company’s internal management and service, enhance the company’s competitiveness, expand market share and establish an excellent corporate image, SwissSEM has decided to start from the second half of 2022, led by the quality department and closely cooperated with all relevant departments, continue to implement environmental management system ISO14001:2015 and occupational health and safety management system ISO45001:2018 certifications. In February 2023, the company successfully passed the above two certifications and obtained them.
In the audit, the audit team of experts through the meeting, discussion exchanges, data review and site survey etc., the company has been carefully audited, and the company leadership has carried out in-depth communication and exchanges, a comprehensive understanding of the enterprise in the environment and occupational health and safety management system implementation and operation. The audit expert group considered that the company’s management system documents were generally appropriate, the operation process was orderly and controlled, and the operation results were effective and compliant, and highly praised our company’s work in system construction, resource assurance, document control and other aspects.
At the same time, the expert group also put forward opinions and suggestions for improvement in the operation of the company’s management system. At present, the company has combined the opinions and suggestions of the expert group, further strengthen the study and understanding of the new version of the management system documents, strictly in accordance with the provisions of the management system documents to perform various work, to ensure the continuous and effective operation of the company’s environmental and occupational health and safety management system.
Relying on the construction of the three systems (ISO9001:2015, ISO14001:2015 and ISO45001:2018), we should work steadily and cultivate our internal skills. The implementation of three system management is an important way for the company to move towards legal management and an important form of full participation in management. Through the effective operation of the system, it helps to improve the staff’s awareness of service, safety and environmental protection. Improve service quality and reduce safety and environmental risks; Avoid economic losses that may be caused by quality, safety, environment and other problems, reduce management costs, and achieve sustainable operation of the company.
