Safety and proper ventilation are critically important aspects of modern DTF print shop operations. The use of specialized inks, adhesive powders, and high-temperature processes creates unique challenges for ensuring healthy working conditions.
DTF Technology Chemical Safety
DTF printing uses specific chemical substances, each with its own safety characteristics. DTF inks contain solvents, dyes, and stabilizers that can release toxic vapors when heated.
DTF Ink Components:
▸ Ethylene glycol
- Concentration: 15-25%
- Main risks: Respiratory irritation
- TLV (mg/cu.m): 10
▸ Isopropanol
- Concentration: 5-15%
- Main risks: Narcotic effect
- TLV (mg/cu.m): 300
▸ Formaldehyde
- Concentration: 0.1-0.5%
- Main risks: Carcinogenicity
- TLV (mg/cu.m): 0.5
DTF Powders and Safety
Adhesive powders contain thermoplastic polymers that can release toxic substances when heated. Automatic shakers help minimize contact with powder.
Regulatory Framework
Print shop safety is regulated by a complex of normative documents, including requirements for ventilation, lighting, and harmful substance control.
Ventilation Systems
Effective ventilation is the foundation of safe operation. The system must provide 8-12 air changes per hour and effective emission filtration.
Fire Safety
DTF production creates increased risks due to the use of flammable materials and high-temperature equipment.
Safety Checklist
Daily checks:
Check ventilation operation Monitor room temperature Verify fire alarm system Check PPE availability
Conclusions
Compliance with safety requirements protects worker health and ensures stable equipment operation. Safety investments pay off through reduced risks and regulatory compliance.
