Important Data
|
Physical State; Appearance:
PALE YELLOW MOBILE OIL
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
producing smoke
and
irritating fumes
.
Reacts
with
strong oxidants
causing fire and explosion hazard.
Occupational Exposure Limits:
TLV: 5 mg/m3 as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2008).
MAK: IIb (not established but data is available); sensitization of skin (Sh); (DFG 2008).
OSHA PEL: TWA 5 mg/m3
NIOSH REL: TWA 5 mg/m3
NIOSH IDLH: 5000 mg/m3 See: 8003347
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation,
through the skin
and
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
The substance may cause effects on the
nervous system
.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact may cause skin sensitization.
Repeated or prolonged inhalation exposure may cause asthma.

|
|
Environmental
Data
|
The substance is very toxic to aquatic organisms.
This substance may be hazardous in the environment; special attention should be given to honey bees.
|
|
N O T E S
|
Pyrethrum is a mixture of pyrethrin I and II, cinerin I and II, and jasmolin I and II.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Do NOT take working clothes home.
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact.
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.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
