I. Core Relationship between ISO 45001 and 3G Antennas
Applicable Scenarios
3G antennas include base station macro antennas and indoor distributed antennas. Their production (e.g., vibrator processing and antenna assembly), on-site installation (e.g., tower base station deployment), and subsequent maintenance all present occupational health and safety risks. ISO 45001 utilizes a closed-loop management system called "risk identification - control - improvement" to cover key aspects such as chemical use (e.g., antenna coating solvents), electromagnetic radiation, and working at height.
Application of Core Clauses
7.4 Communication Management: A cross-departmental safety information transmission mechanism must be established, such as chemical risk notification between production workshops and storage departments, and radiation protection briefings for base station construction teams.
Hazard Identification (6.1.2): Identify core risks based on the characteristics of 3G antennas (see below).
Emergency Preparedness (8.2): Develop specific contingency plans for scenarios such as chemical leaks and falls from heights, referencing practical experience in zero-accident management.
II. Key Safety Risk Management Points for the 3G Antenna Process
Manufacturing
Typical risks include chemical exposure (such as solvents used in antenna surface treatment and welding flux) and mechanical damage (such as antenna element stamping and antenna housing cutting). In accordance with ISO 45001, a "five-double" storage system (two people for receiving and sending, two locks, two accounts, two inventory checks, and two transportation) is required. MSDSs (Material Safety Data Sheets) must be posted, and monthly leak risk inspections must be conducted. Safety interlocks must also be installed on stamping and cutting equipment. Employees must hold certifications and receive regular skills refresher training to ensure operational compliance.
Onsite Construction
The main risks are electromagnetic radiation (typical 3G frequency bands: 824-960MHz, 1710-2170MHz) and falls from height (for tower base station installation). Low-radiation tools must be used for control, and radiation field strength must be monitored in real time to ensure compliance with the safety standard of ≤40μW/cm². Workers must wear dedicated electromagnetic protection wristbands. Double-hook safety belts are mandatory for overhead work, and guardrails must be installed on the work platform. Outdoor construction must be immediately halted when weather conditions reach level 6 or above, with strong winds or heavy rain.
Maintenance and Inspection Phase
The core risk is electric shock accidents (such as during 3G base station equipment commissioning and antenna feeder connection). A "power outage sign" system must be strictly implemented. Warning signs must be displayed after disconnecting equipment from the power source. Regularly calibrated and qualified insulated tools must be used to avoid working with live power. Work areas must also be fenced off to prevent unauthorized access.
III. Enterprise Certification Practices and Results
Practical Results
Some enterprises have achieved ISO 45001 certification, integrating quality (ISO 9001) and environmental (ISO 14001) management systems. This has resulted in zero incidents with partners during the production and construction of 3G antennas, significantly improving employee safety awareness. Some communications equipment companies have integrated ISO 45001 certification with 3G antenna product quality control, prioritizing OHS (occupational health and safety) compliance during customer acceptance inspections, significantly improving order conversion rates.
Common Non-Compliances
Mixed oxidizing and reducing agents in the chemical warehouse (violating the isolation requirements of ISO 45001, Section 5.3.3).
Failure to establish a warning zone for the electromagnetic radiation impact area before 3G base station construction (missing the external communication records required by ISO 45001, Section 7.4.3).
IV. Implementation Recommendations
Risk-Based Management: Quantitatively assess risk using the LEC (Low Risk Evaluation) method. For example, a 3G antenna welding station with a risk value >160 is considered high risk. Targeted engineering and personal protective measures, such as automatic fume exhaust systems and welding masks, are implemented.
Application of Digital Tools: Develop a safety inspection app to upload real-time 3G base station radiation monitoring data, equipment maintenance records, and hazard rectification status, ensuring full traceability of occupational health and safety risk management.
Extension of psychological safety: Combined with ISO 45003 (Guidelines for psychological factors of occupational health and safety management systems), regular psychological counseling services are provided to personnel in high-risk positions such as 3G base station high-altitude operations and field inspections to reduce the probability of safety accidents caused by human errors.
