Ozone
Properties
of ozone is described
below
PHYSICAL STATE; APPEARANCE:
COLOURLESS OR BLUISH GAS , WITH CHARACTERISTIC ODOUR.
PHYSICAL DANGERS:
The gas is heavier than air.
CHEMICAL DANGERS:
The substance decomposes on warming producing oxygen , which
increases fire hazard. The substance is a strong oxidant and reacts
violently with combustible and reducing materials. Reacts with alkenes,
aromatics such as aniline, and ethers, bromine, nitrogen compounds and
rubber producing shock-sensitive compounds. Attacks metals except gold
and platinum.
OCCUPATIONAL EXPOSURE LIMITS:
TLV: (light work) 0.1 ppm as TWA; TLV: (moderate work) 0.08 ppm as
TWA; TLV: (heavy work) 0.05 ppm as TWA; A4; (ACGIH 2004).
OSHA PEL: TWA 0.1 ppm (0.2 mg/m3)
NIOSH REL: C 0.1 ppm (0.2 mg/m3)
NIOSH IDLH: 5 ppm
ROUTES OF EXPOSURE:
The substance can be
absorbed into the body by inhalation.
INHALATION RISK:
A harmful concentration of this gas in the air will be reached very
quickly on loss of containment.
EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes and the respiratory tract.
Inhalation of the gas may cause lung oedema (see Notes). Inhalation of
the gas may cause asthmatic reactions (see Notes). The liquid may cause
frostbite. The substance may cause effects on the central nervous system
, resulting in headache and impaired vigilance and performance.
EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Lungs may be affected by repeated or prolonged exposure to the gas.
