| Firefighting Hazards | Exposure to extreme heat can give rise to thermal decomposition. |
| Brandbekämpfungsverfahren | When fire fighting conditions are severe and total thermal decomposition of the product is possible, wear full protective clothing, including helmet, self-contained, positive pressure or pressure demand breathing apparatus, bunker coat and pants, bands around arms, waist and legs, face mask, and protective covering for exposed areas of the head. No unusual effects are anticipated during fire extinguishing operations. Avoid breathing the products and substances that may result from the thermal decomposition of the product or the other substances in the fire zone. Keep containers cool with water spray when exposed to fire to avoid rupture. |

Anwendungen & Verwendung
Verwenden
Ultrasound contrast agent intended for assessing myocardial perfusion in patients with coronary artery disease.
Verwenden
DECAFLUOROBUTANE (DFB) is used as a novel core material for phase-change contrast agents (PCCAs). Its mechanism of action is as follows: whilst DFB is naturally a gas at room temperature (boiling point –1.7 °C), it can be encapsulated within a lipid shell to form supercooled liquid nano- and micrometre-scale droplets that remain stable at physiological temperatures; when excited by ultrasonic energy, the droplets undergo acoustic droplet vapourisation (ADV), transforming into highly echogenic microbubbles, thereby producing ultrasonic contrast [1].
