1 Product Identification

2 Hazardous Ingredients

No toxic chemical(s) subject to reporting requirements of section 313 or Title III and 40 CFR 372 present.–

3 Health Hazards

Method of entry: Inhalation: Yes Skin: No Ingestion: No

Health Hazards (Acute and Chronic): It is unlikely a hazardous condition will exist or be created when working with this product. The ingredients are encapsulated in polypropylene and polyethylene and unless the product construction is destroyed or severely altered, the ingredients will remain in the encapsulated state.

The regulated material in the product is Carbon Black (CAS No. 1333-86-4) which has an exposure limit 3.5 Mg/M3 as an 8-hour Time Weighted Average. The product would have to be crushed and ground into powder in order to free the carbon black before it would present a hazard.

Six independent studies were conducted with trifluralin, the active ingredient in this product. Four studies showed no carcinogenic effect. The two other studies were found flawed. Therefore, it is concluded trifluralin is not carcinogenic. The 1992 Registry of Toxic Effects of Chemical Substances (1992 RTECS) reports Trifluralin as a reproductive toxin.

Carcinogenicity: NTP: No IARC Monographs: No OSHA Regulated: No

Signs and Symptoms of Exposure: Inhalation of vapors may irritate eyes and nose. Avoid skin contact as it may cause skin irritation in certain individuals.

Medical Conditions Generally Aggravated by Exposure: None known

4 First Aid/Emergency Procedures

Emergency and First Aid Procedures: If eyes are irritated, flush them with plenty of water. If on the skin, wash thoroughly with soap and water. If irritation or symptoms continue, get medical attention.

Hazardous polymerization: Will not occur

8 Precautions for Safe Handling and Use

Steps to be taken in Case Material is Released or Spilled: No special precautions required.

Waste Disposal Method: Landfill in accordance with Federal, State or local laws and ordinances.

Precautions to be Taken in Handling and Storage: Avoid contact with eyes and skin. Avoid breathing smoke or vapors if the product is heated to decomposition. Keep material in original sealed package until ready for use. Store in a dry place and do not expose to direct sunlight.

Other Precautions: None — Not Regulated by OSHA or DOT.

9 Control Measures

Respiratory Protection: Respiratory protection is not generally required under normal use conditions. If concentrations exceed the PEL, use NIOSH/MSHA approved respirators.

Ventilation: Local Exhaust: Not Required Mechanical ( General): Heating and cooling systems will normally provide adequate air movement.

Protective Gloves: Ordinary work gloves to prevent excessive skin contact are suggested.

Eye Protection: None

Other Protective Clothing or Equipment: Coveralls or long-sleeved shirt and gloves are recommended to avoid skin staining.

Work/Hygienic Practices: Wash thoroughly before eating, drinking, smoking or leaving the work place. Consult 29 CFR 1910.141 General requirements for sanitation.
