HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW:
WARNING: May cause eye and skin irritation. Harmful if swallowed. Avoid
inhaling dust. Do not contaminate feed or foodstuffs.
KEEP OUT OF REACH OF CHILDREN.
Toxic to fish and aquatic organisms.
POTENTIAL HEALTH EFFECTS
ROUTE(S) OF ENTRY: Ingestion, inhalation, eye contact, and skin contact.
SIGNS OF ACUTE OVEREXPOSURE: A person suffering from acute exposure to this product may
suffer from mild eye irritation. In addition, exposure to Permethrin may induce adverse effectson the nervous system. Symptoms include hypersensitivity, tremors, unsteady gait, andsalivation. Other possible signs of overexposure include facial erythema (flushing) and facialskin tingling.
SIGNS OF CHRONIC OVEREXPOSURE: Prolonged exposure to high atmospheric
concentrations of respirable dust of amorphous silica may cause non-progressive fibrosisof the lungs; amorphous silica does not cause silicosis.
OTHER POTENTIAL HEALTH EFFECTS: No evidence of mutagenic or teratogenic potential has
been observed. EPA (2004) has evaluated the carcinogenic potential of Permethrin underits ‘Review Draft of the Guidelines fro Carcinogen Risk Assessment (1999)’. Permethrinhas suggestive evidence of carcinogenicity but not sufficient to assess humancarcinogenic potential.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: None known.
CARE SHOULD BE EXERCISED IN HANDLING PERMETHRIN AND ITS FORMULATIONS
FIRST AID MEASURES
EYES: Immediately flush the eyes with copious amounts of clear, cool running water for a minimum
of 15 minutes. Hold the eyelids apart during the flushing to ensure rinsing of the entiresurface of the eyes and lids with water. Contact a physician immediately. If there will be adelay in getting medical attention, rinse the eyes for at least another 15 minutes.

EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS: Ventilation should be sufficient to keep the exposure below the TLV.
Use of mechanical or local exhaust systems is recommended when dust formation is possible.
RESPIRATORY PROTECTION: For exposures outdoors that may exceed the TLV, a Dust/Mist
filtering respirator (MSHA/NIOSH approval number prefix TC-21C) is required . Forexposures in enclosed areas that may exceed the TLV, a respirator with either an organicvapor-removing cartridge with a prefilter approved for pesticides (MSHA/NIOSH approvalnumber prefix TC-23C), or a canister approved for pesticides (MSHA/NIOSH approvalnumber prefix TC-14G) is required.
SKIN PROTECTION: Applicators and other handlers must wear long-sleeved shirt and long pants;
waterproof gloves; and shoes plus socks. Follow manufacturer's instructions for cleaning/maintaining personal protection equipment (PPE). If no such instructions are available, usedetergent and hot water. Keep and wash PPE separately from other laundry.
EYE PROTECTION: Safety glasses with sideshields should be used whenever hazardous chemicals
are being handled. Tight fitting chemical goggles should be worn whenever there is a chanceof dusting from the product.
OTHER PROTECTION: There should be an eyewash station and a safety shower in the work area.
