zh Foundry Safety Code (AQ 7016—2025)
2025-06-27 16:36:54 hits：0
The Foundry Safety Code (AQ 7016—2025) is a mandatory industrial safety standard formulated for Chinese foundry production enterprises. It aims to regulate requirements for buildings, working environments, equipment, process operations, and safety management in foundry production.
The Foundry Safety Code AQ 7016—2025 revises and updates the 2018 version, with main improvements including:
Stricter technical requirements for molten metal handling and dust explosion prevention
More systematic safety management systems (dual prevention mechanisms, contractor responsibilities)
A more precise scope of application (excluding metallurgical continuous casting enterprises)
Detailed operation specifications for confined spaces, pouring operations, etc.
Specific differences are reflected in the following aspects:
| Comparison Item | AQ 7016—2025 (New Version) | AQ 7016—2018 (Old Version) | Main Changes |
|---|---|---|---|
| Scope of Application | Clearly excludes continuous casting and ingot casting in metallurgical industries. | Does not explicitly exclude metallurgical continuous casting enterprises. | Narrowed scope for more precise applicability. |
| Buildings & Working Environment | 1. Personnel gathering areas (e.g., conference rooms, rest areas) are prohibited below molten metal lifting zones; physical enclosures are required. 2. Roof waterproof grade in smelting/pouring areas ≥ Class II; overhead water pipes are prohibited. 3. Specified passage widths (e.g., vehicle lanes ≥ 3500mm, manual molding walkways ≥ 800mm). | 1. No explicit restrictions on personnel gathering areas. 2. General roof waterproofing requirements. 3. Lack of specific passage width standards. | New physical restrictions to enhance safety baselines. |
| Equipment Safety | 1. Smelting equipment: Induction furnaces require emergency power supplies and leakage alarms; gas furnaces need flame monitoring and flameout protection. 2. Molten metal transportation: Ladle hooks must not be castings; transport equipment requires anti-fall devices and interlocks. 3. Dust explosion prevention: Aluminum-magnesium dust must be cleaned daily (thickness ≤0.8mm); positive-pressure dust removal is prohibited. | 1. Incomplete safety requirements for some equipment. 2. No specified dust cleaning standards. | New safety measures for critical equipment; strengthened explosion prevention. |
| Process Operation Safety | 1. Smelting operations: Closed containers and wet materials are prohibited from entering the furnace; furnace repair temperature must be ≤50℃. 2. Pouring operations: Ladle liquid level clearances comply with GB/T 23583.1; lifting paths must avoid personnel areas. 3. Confined space operations: Mandatory "ventilate-detect-operate" procedures with warning signs. | 1. Fragmented operation specifications. 2. Unclear confined space protocols. | Refined high-risk process guidelines for improved operability. |
| Safety Management | 1. Mandatory establishment of a dual prevention mechanism (risk hierarchical control + hidden danger investigation). 2. New requirements for contractor safety management agreements. 3. Smelting/pouring positions require specialized training; special operators must be certified. | 1. Brief safety management clauses. 2. No emphasis on dual prevention mechanisms. | Enhanced enterprise primary responsibilities and management systems. |
| Referenced Standards | Updated to reference the latest standards, including: - GB 11291.1-2 (Industrial Robot Safety) - AQ 4272 (Aluminum-Magnesium Dust Explosion Prevention) - GB/T 33579 (Lockout/Tagout, LOTO) | Outdated references (e.g., missing robot safety requirements). | Aligned with the latest safety technology standards. |
| Terms & Definitions | New terms added (e.g., "voltage section," "lockout device"). | Fewer defined terms. | Clearer technical classification. |
