1 Scope

GB 30188-2013 is the Chinese national standard on code of dust and poison control for welding electrodes production, in the field of environment and health protection, safety. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 31 December 2013 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 December 2014. Classification: ICS 13.100, CCS C70. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the welding production industry dust and poison General, site selection, plant and plant dust and poison control requirements, technology Dust Antivirus request confined dust source dust and ventilation measures, personal protection and dust and poison control measures. This standard applies to all welding manufacturer of dust and poison design, transformation and management of occupational health.
