Alcance y aplicabilidad

This standard applies to lead smelting, lead salt production, lead-acid battery manufacturing, cable production, as well as lead-related operations in the paint, plastic, glass, ceramic, and shipbuilding industries. It is mandatory for all enterprises engaged in the sintering, reduction, melting, casting, and recycling of lead and its compounds. The standard specifically excludes obsolete lead printing operations, which have been removed from the 1992 version.

Requisitos técnicos

The standard specifies comprehensive occupational safety and hygiene requirements for lead operations. It mandates that facilities conduct occupational hazard assessments and safety evaluations during the design phase. Workplaces generating lead fumes or dust must be isolated and located on the upwind side of the minimum frequency wind direction. The standard sets strict environmental limits, including a time-weighted average allowable concentration for lead fume and lead dust in the air, alongside an 8-hour continuous noise exposure limit of 85dB(A). For process equipment, the standard outlines specific containment and ventilation requirements across various industries. For example, lead melting pots in battery and lead salt production must be equipped with closed exhaust purification systems or surface covering layers. Ball mills, casting machines, and welding stations must utilize localized exhaust systems to prevent lead dust dispersion. The standard also requires automatic temperature control or over-temperature alarms for melting pots. Regarding storage and transportation, lead materials are strictly prohibited from open-air stacking and must be stored in dedicated, fire-resistant, well-ventilated warehouses. Powdered lead must be packaged in dedicated, damage-resistant containers during transportation to prevent leakage. Hazardous solid waste containing lead must be managed according to GB 15603. The management chapter requires enterprises to establish occupational safety and health departments, conduct regular employee training, and provide adequate personal protective equipment (PPE). Enterprises must organize annual occupational health examinations for all lead-exposed workers and establish emergency response plans. Workplaces must strictly prohibit eating, drinking, or smoking, and workers must shower and change clothes before leaving the facility.

Métodos de ensayo

The standard requires regular monitoring of lead fume and dust concentrations in the workplace, with sampling and determination methods referenced from GB 13733. Enterprises must conduct these air concentration tests at least once a month under normal operating conditions. Additionally, the performance and purification efficiency of dust and poison prevention facilities must be tested annually to ensure they meet regulatory requirements.

Preguntas frecuentes

What products and industries are regulated under GB 13746-2008?

This standard applies to lead smelting, lead salt production, lead-acid battery manufacturing, cable production, as well as lead-related operations in the paint, plastic, glass, ceramic, and shipbuilding industries. It replaces the previous GB 13746-1992 version, removing obsolete lead printing operations and adding new industrial categories.

Are there any significant updates from the previous GB 13746-1992 version?

The updated version introduces a new chapter on general requirements, covering site selection, electrical and mechanical safety, and noise limits. It also refines the definition of 'lead' and 'lead operations', and adds comprehensive requirements for occupational health monitoring and safety management systems, which were not detailed in the 1992 version.

How does GB 13746-2008 relate to international standards?

While it does not directly adopt ISO standards, it references several Chinese national standards (GB) for design, sampling, and safety. For instance, workplace air sampling must follow GB 13733, and workplace hazard grading follows GB/T 16180. Engineers must ensure compliance with these referenced Chinese GB standards alongside GB 13746-2008.
