PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
CLEAR COLOURLESS LIQUID WITH PUNGENT ODOUR. 

Physical dangers
 

Chemical dangers
The substance is a strong reducing agent. It reacts with strong bases, strong acids and strong oxidants. This generates fire and explosion hazard. 

Formula: C5H8O2 / HCO(CH2)3CHO
Molecular mass: 100.1
Boiling point: 101°C
Melting point: -33°C
Density: 1.33 g/cm³
Solubility in water: miscible
Vapour pressure, kPa at 20°C: 2.3
Relative vapour density (air = 1): 1.05
Flash point: >95°C c.c.
Viscosity: 12.75 mm²/s at 25°C 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. 

Inhalation risk
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. See Notes. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.05 ppm as STEL; (SEN); A4 (not classifiable as a human carcinogen).
MAK: 0.21 mg/m3, 0.05 ppm; peak limitation category: I(2); sensitization of respiratory tract and skin (SAH); carcinogen category: 4; pregnancy risk group: C 

ENVIRONMENT
The substance is very toxic to aquatic organisms. 

NOTES
The occupational exposure limit value should not be exceeded during any part of the working exposure.
The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance.
See ICSC 0158.
