Physical and Chemical Characteristics

- Physical state:  Liquid
- Color:  Colorless
- Odor:  Strong ether-like odor
- Boiling Point:  76.75 degrees C
- Freezing Point:  -23 degrees C
- Vapor Density:  5.32 (air=l)
- Melting Point: -23 degrees C (-9 degrees F)

                          4. REGULATORY POSITION

- Position Document 1 issued October 15, 1980.
- OPP issued a Data-Call-In Notice in March 1984 requiring submission of
  reproduction (l species), teratogenicity (2 species), residue chemistry
  data, updated Confidential Statements of Formula and product chemistry
  data.
- On April 23, 1986 a notice announcing the availability of the draft PD
  2/3/4 was published in the Federal Register.
- The Agency is issuing a Notice of Intent to Cancel all pesticide products
  containing carbon tetrachloride based on oncogenic risk and other effects in
  laboratory animals. This notice cancels all carbon tetrachloride
  registrations already suspended for non-compliance with the above mentioned
  Data-Call-In Notice. The use on encased museum specimens, which was not
  subject to the March 1984 Data Call-In, will be allowed to continue because
  the current label instructions are sufficient to reduce applicator exposure
  so that the benefits outweighed the risks.

                              5. CONCERNS

- Significant data are available which suggest that carbon tetrachloride
poses significant health and environmental hazards.

- Has been shown to pose acute and subacute poisoning risks.

- Has been shown to cause oncogenic effects in laboratory animals.

- May contribute to the breakdown of the atmosphere's ozone layer.
