Keystone Vessel BF₃ (Boron Trifluoride) 615L Spherical Tank Technical Specifications & Safety Guidelines

BF₃ (Boron Trifluoride) is a highly toxic, corrosive, and hydrolyzable gas that poses significant risks to human health and the environment. The 615L spherical tank designed for BF₃ storage and transportation adopts high-quality materials and dual certifications to ensure safe and compliant operation. The following are the detailed technical specifications, certification information, and safety requirements.

I. Core Technical Specifications

II. Certification Information (Domestic & EU Dual Certification)

• DOT Certification: Complies with the U.S. Department of Transportation (DOT) standards for high-pressure gas containers, covering material quality, structural design, pressure resistance, and safety performance, enabling legal circulation in North American and DOT-recognized regions.

• TPED Certification: Meets the requirements of the European Pressure Equipment Directive (TPED, 2014/68/EU), which specifies strict safety standards for pressure equipment used in the EU market, including design, manufacturing, inspection, and marking, ensuring compliant use and circulation within the EU.

• Domestic Certification: Conforms to Chinese national standards such as GB/T 12337《Spherical Pressure Vessels》and TSG R0006《Safety Supervision Regulations for Pressure Vessels》, with complete inspection certificates and supervision records .

III. Key Safety Requirements for Storage & Transportation

1. Storage Safety Norms

• Storage Environment: Store in a dedicated, cool, dry, and well-ventilated toxic gas warehouse; avoid direct sunlight and heat sources (ambient temperature ≤ 30℃); relative humidity ≤ 30% to prevent BF₃ hydrolysis . The warehouse should be equipped with BF₃ gas detection and alarm devices (alarm threshold ≤ 1 mg/m³, consistent with ACGIH TLV-C standards) and emergency absorption equipment (alkaline solution such as caustic potassium for neutralization ).

• Isolation Requirements: Store separately from water, alcohols, amines, alkalis, and food; keep a distance of ≥ 15 meters from open flames and heat sources; post obvious warning signs such as "Toxic Gas", "Corrosive", and "No Open Flame" .

• Tank Placement: Place on a stable, flat foundation, fixed with anti-displacement devices to prevent tipping or collision; regularly check the tank body for corrosion, deformation, and valve sealing .

• Routine Inspection: Daily inspection of pressure gauge readings (maintaining normal working pressure range) and gas detection alarms; weekly leak test using soapy water or professional gas detectors (BF₃ can be identified by white smoke in moist air ); annual comprehensive inspection including wall thickness measurement and safety accessory calibration.

2. Transportation Safety Norms

• Transport Vehicle Requirements: Use dedicated dangerous goods transport vehicles with anti-static, anti-corrosion, and pressure-resistant modifications; drivers and escorts must hold hazardous chemicals transport qualifications and be familiar with BF₃ hazard characteristics and emergency disposal methods .

• Loading & Fixing: Secure the spherical tank firmly with dedicated brackets during transportation to avoid vibration and collision; ensure the valve is sealed and protected with a valve cap; strictly prohibit mixing with incompatible goods (e.g., water, oxidants) .

• Transportation Environment: Avoid transportation in extreme temperatures (below -30℃ or above 50℃); take sunshade and heat insulation measures in summer; prevent rain and moisture intrusion .

• Labeling & Documentation: Affix DOT and TPED certification marks, hazard labels (toxic, corrosive), and transportation documents (including SDS, certification certificates, and inspection reports) on the vehicle .

IV. Safe Operation Guidelines

1. Pre-Use Preparation

• Operators must receive professional training, be familiar with BF₃ hazard characteristics and operating procedures, and pass assessments before taking up posts .

• Wear personal protective equipment (PPE): full-face positive pressure air respirator, chemical protective clothing (isolation type), fluororubber gloves, and anti-corrosion boots; prohibit wearing chemical fiber clothing to avoid static electricity .

• Check the tank body, valves, and connecting pipelines for intactness; purge the pipeline system with inert gas (nitrogen) to remove moisture and air before connection (moisture can cause BF₃ hydrolysis and equipment corrosion ).

2. In-Use Operation

• Open the valve slowly to avoid pressure surges; purge the interface with a small flow of BF₃ for 30 seconds before connecting to the process system; strictly control the gas flow rate according to process requirements .

• Real-time monitor the BF₃ concentration in the operation area; if the alarm is triggered, immediately close the valve, stop operation, and ventilate with inert gas until the concentration returns to a safe level .

• Prohibit knocking, colliding, or welding the tank body; do not arbitrarily increase the pressure of the tank or transfer gas between containers .

3. Post-Use Treatment

• After use, close the main valve first, then purge residual BF₃ in the pipeline with inert gas to prevent hydrolysis and pipeline blockage .

• Seal the valve port with a dedicated plug, record the usage time, dosage, and residual pressure, and transfer the tank back to the dedicated storage area .

• Do not empty the BF₃ in the tank completely; keep a residual pressure of ≥ 0.5 MPa to prevent external air and moisture from entering .

V. Emergency Disposal Measures

1. Leakage Handling

• Immediately isolate the leak area, set up a warning zone (≥ 50 meters for small leaks, ≥ 100 meters for large leaks), and evacuate irrelevant personnel from the upwind direction .

• Emergency personnel must wear full protective equipment; use alkaline solution-soaked cloth or lime to cover and neutralize the leak (avoid direct water flushing, which may cause violent hydrolysis of BF₃ ).

• For large-scale leaks, use spray water to suppress vapor diffusion and guide the gas to an emergency absorption system (alkaline solution absorption) .

2. Personnel Injury First Aid

• Inhalation: Transfer the patient to a well-ventilated area with fresh air, keep the respiratory tract unobstructed, give oxygen if necessary, and seek medical attention immediately .

• Skin Contact: Immediately remove contaminated clothing, rinse the affected area with a large amount of flowing water for at least 15 minutes, and seek medical attention .

• Eye Contact: Separate the eyelids, rinse thoroughly with flowing water or normal saline for 5-10 minutes (remove contact lenses if possible), and seek medical attention immediately .

3. Fire Handling

• BF₃ itself is non-flammable; select appropriate fire extinguishers (dry powder, carbon dioxide, or foam) according to the cause of the fire .

• Firefighters must operate from the upwind direction, wear full protective equipment, cool the tank body with water spray, and move the tank to an open area if possible .

VI. Maintenance & Scrap Disposal

• Daily Maintenance: Keep the tank surface clean; wipe with anhydrous ethanol regularly to remove dust and corrosive residues; avoid contact with water and acidic/alkaline substances .

• Periodic Inspection: Conduct a comprehensive inspection every 3 years (hydrostatic test, wall thickness measurement, and safety accessory calibration); for containers with corrosion pits or wall thickness reduction exceeding 10%, stop using them immediately and apply for scrap .

• Scrap Disposal: Entrust professional institutions with hazardous waste disposal qualifications to purge residual BF₃ with inert gas, neutralize it with alkaline solution, and then perform harmless treatment (cutting, recycling, or destruction); establish a scrap account with a retention period of not less than 5 years .
