POTENTIAL HEALTH EFFECTS:
ROUTE(S) OF ENTRY..................: Inhalation; Skin Contact; Eye Contact
HUMAN EFFECTS AND SYMPTOMS OF OVEREXPOSURE:
ACUTE EFFECTS OF EXPOSURE.....: Exposure during the labeled use of this product
is expected to be minimal. Consumers should refer to the packaging label
for proper handling procedures. Sufficient exposure to cyfluthrin, the
active ingredient in this product, may cause eye or skin irritation
characterized by redness or itching. In addition, sufficient exposure to
cyfluthrin may produce paraesthesia (a tingling or burning sensation on the
surface of the skin. This is a frequently reported symptom associated with
sufficient dermal exposure to alpha-cyano (Type II) synthetic pyrethroids
and normally subsides without treatment within 24 hours. The onset of
these symptoms usually occurs 2-12 hours after exposure. Mucous membrane
irritation involving the nose, throat and upper respiratory tract may occur
from inhalation of aerosols containing cyfluthrin. Based on EPA Toxicity
Category criteria, this material is mildly toxic by the oral and dermal
routes of exposure. See Animal Toxicity Section for additional
information.
CHRONIC EFFECTS OF EXPOSURE...: Based on animal studies, no adverse effects or
symptoms would be expected from chronic exposure to the active ingredient
in this product during normal use. This product may contain up to
approximately 0.3% total crystalline silica. However, the amount of
respirable crystalline silica is expected to be significantly lower based
on data provided by the raw material manufacturer. Excessive long-term
exposure to respirable crystalline silica may cause silicosis, a form of
progressive pulmonary fibrosis. Severe and permanent lung damage may
result.
CARCINOGENICITY...............: This product is not listed as a carcinogen by
NTP or IARC, or regulated as a carcinogen by OSHA. However, it may contain
crystalline silica (quartz), a substance which is classified by NTP as a
Group 2 carcinogen and by IARC as a Group I carcinogen. Crystalline silica
is a naturally-occurring mineral component of many sands and clays.
Although controversial, the carcinogenic potential of crystalline silica
must be considered if it is inhaled under excessive exposure conditions.
However, the respirable portion of the silica which may be contained in
this product is small, such that excessive inhalation exposure during
