MANIPOLAZIONE E STOCCAGGIO
Manipulation
Action/technical precautions: Provide sufficient air exchange and/or exhaust in work rooms.
Recommendations for safe use: Do not breathe vapors or spray mist.
Storage: Close tightly and store in a cool, dry and well ventilated place.
Store in original container. Incompatible products: explosive, flammable materials, Organic peroxide
EXPOSURE CONTROL / PERSONAL PROTECTION
Control parameters: AEL (8 ‐ h e 12 ‐ h TWA) = 1000 ml/m³ for each of the two components.
Respiratory protection: For rescue and maintenance operation in storage tanks use self ‐ contained respirator apparatus.
The vapors are heavier than air and can cause suffocation by reducing oxygen available for breathing.
Eyes protection: Safety glasses.
Protection of hands: Rubber gloves.
Hygiene measures: Do not smoke.
PHYSICAL AND CHEMICAL PROPERTIES
Colour: Colourless.
Odor: Light.
Boiling point: ‐ 52.8°C at atmospheric pressure.
Lighting point: do not ignite.
Relative density: 1.08 kg/l at 25°C.
Solubility in water: Negligible.
STABILITY AND REACTIVITY
Stability: No reactivity when used with the appropriate instructions.
Materials to avoid: Highly oxidizing materials. Incompatible with magnesium, zinc, sodium, potassium and aluminum.
The incompatibility is more serious if the metal is present in powerder form or if the surfaces were, recently, unprotected.
Decomposition products These products are halogenated compounds, hydrogen fluoride, carbon oxides (CO, CO2), carbonyl halides.
