Strict safety regulations apply in both laboratory and fluid engineering settings. Proper sizing to match operating pressure is as critical as using suitable connectors and fittings. Regular maintenance, observing minimum bending radii, and protection from mechanical damage are also crucial for safe operation. Only by carefully considering all these factors can the safety and reliability of gas systems be ensured.
