ISO 45001 GSM Antenna

　　I. ISO 45001-certified Occupational Health and Safety Management System

　　GSM antenna companies that have achieved ISO 45001 certification must establish a comprehensive occupational health and safety management system, focusing on personnel safety and operational protection. Specifically, this includes:

　　Production Safety Management

　　Specific safety measures are implemented for key processes involved in GSM antenna production (such as metal oscillator cutting, RF welding, and PCB substrate processing). Metal processing steps must be equipped with mechanical safeguards (such as protective covers and emergency stop buttons) to prevent physical contact risks. Fume extraction systems (with a dust collection efficiency of ≥90%) must be installed during welding processes, and operators must be equipped with dust and gas masks to reduce respiratory health risks. Anti-static grounding devices must be installed in processing areas for electrostatically sensitive components (such as RF connectors). Operators must wear anti-static clothing and wristbands. ESD protection areas must be designated and warning signs must be posted to prevent electrostatic damage and electric shock.

　　Personnel Health Protection Mechanism

　　A system for employee health monitoring has been established. For those in positions with long-term exposure to welding fumes and high-frequency equipment, occupational health examinations (focusing on lung function, hearing, and other indicators) are conducted every six months. For high-intensity tasks (such as handling large base station antenna components), physical labor quotas are set, and hydraulic lifting equipment is provided to assist with handling to prevent muscle strain. Regular occupational health and safety training (at least four times per year) covers safe equipment operation and emergency response (such as fire and electric shock first aid) to ensure that employees master basic safety skills.

　　Safety and Compliance Throughout the Supply Chain

　　For the handling of raw materials (such as aluminum alloy and PCB substrates), standard stacking heights are maintained (no more than 1.5 meters) and non-slip mats are installed to prevent injuries from material collapse. Fire escapes (≥1.2 meters wide) are designated in the finished product storage area and are equipped with dry powder fire extinguishers and smoke detectors to comply with fire safety standards. For product transportation, heavy components such as vehicle-mounted antennas are enclosed in fixed brackets to prevent vibration and potential collisions during transportation. Safe handling procedures are also provided to transporters.

　　II. Key Points Related to GSM Antenna Core Technical Parameters and Safety

　　(I) Key Electrical Performance Indicators (Taking into Account Both Technical and Application Safety)

　　GSM antenna electrical performance must comply with communications industry standards, and some parameters are indirectly related to operational safety: The operating frequency bands are primarily 900MHz/1800MHz dual-band. Frequency stability reduces safety hazards caused by abnormal device heating. The VSWR (standing wave ratio) should be ≤1.5 in conventional scenarios and ≤2.0 in vehicle-mounted scenarios. A low VSWR reduces RF energy loss during signal transmission and prevents localized overheating. Gain is 5-7dBi for built-in models and 10-15dBi for base station models. A reasonable gain reduces excessive energy consumption to boost the signal and mitigates the risk of circuit overload. The input impedance is uniformly 50Ω, matching the device interface to prevent circuit damage or abnormal discharge caused by impedance mismatch.

　　(II) Mechanical Characteristics and Safety Compatibility

　　The mechanical characteristics of GSM antennas in different scenarios must balance functionality and safety. Built-in consumer electronics antennas (such as mobile phone antennas) are made of PCB or FPC, with a thickness of 0.8-1.6mm (FPC is bendable). This miniaturized design reduces internal device space and reduces the risk of component collision during assembly. Vehicle-mounted antennas are constructed with ABS/aluminum alloy housings and must meet a vibration resistance rating of ≤10g within the 10Hz-2000Hz frequency band to prevent the antenna from falling off or components from loosening due to vehicle turbulence. The housing edges are rounded to prevent scratches during installation. Base station antennas are constructed with fiberglass outer layers and have an IP67 rating, which protects against temperature fluctuations from -40°C to +85°C and rain intrusion. They also feature lightning protection grounding connectors to reduce the risk of lightning strikes during thunderstorms. Installation must comply with lightning protection and grounding specifications.

　　III. Mainstream Product Types and Safety Application Scenarios

　　GSM antennas can be divided into three categories based on their application scenarios, each requiring compliance with ISO 45001 safety requirements:

　　Built-in antennas for consumer electronics

　　For use in mobile phones and handheld devices, they must be compact (≤30mm × 30mm) and low power. Assembly requires no complex tools, reducing operator difficulty and the risk of hand strain. The product's surface should be free of sharp protrusions to prevent scratches during use.

　　In-vehicle GSM antennas

　　For use in in-vehicle navigation and connected car terminals, they often integrate multi-mode functionality (such as GSM + GPS). Mounting options include 3M adhesive or pole mounting. Adhesive mounting eliminates drilling, reducing the risk of mechanical damage during installation. The housing's high-temperature resistance must be compatible with high-temperature vehicle environments (e.g., summer temperatures exceeding 60°C) to prevent deformation and the release of harmful substances.

　　Base Station GSM Antennas

　　For outdoor communication coverage, these are typically large, integrated structures weighing ≥5kg. They require a dedicated lifting interface and must be installed with aerial work equipment to prevent falls or injuries from manual handling. The antenna base is equipped with a safety latch that must be secured and locked after installation to prevent displacement or falls in windy conditions.

　　IV. Key Selection Recommendations (Including ISO 45001 Safety Verification)

　　Technology and Safety Compatibility

　　For consumer electronics applications, prioritize lightweight, built-in antennas without sharp edges (weighing ≤10g) to minimize assembly and operation safety hazards. For automotive applications, verify the antenna's vibration resistance (≥10g) and high-temperature resistance (-40°C to +85°C) to avoid safety issues caused by vehicle operating conditions. For base station applications, focus on lightning protection design (including grounding interfaces) and a safe lifting structure to ensure compliance with aerial installation standards.

　　ISO 45001 Qualification Verification

　　When selecting a product, confirm that the supplier holds ISO 45001 certification. Verify their safety control measures during production (such as welding fume treatment, electrostatic protection, and employee health monitoring records) to avoid purchasing products without safety and compliance assurances. If custom production is involved, request that the supplier provide safety operating plans for the custom processes to ensure that there are no occupational health risks in the production process.

　　Installation and Usage Safety Tips

　　Base station antenna installation must be performed by personnel qualified for working at heights. Personnel must wear a safety harness and helmet and adhere to the "grounding before installation" principle. When attaching vehicle antennas, the mounting surface must be clean to prevent loosening of the adhesive. When repairing consumer electronics antennas, use anti-static tools to prevent static damage to components and protect the operator.
