San Francisco, California.
1. NOAA /OMA was notified of the incident at approximately 1430 on February 4, 1989 by the U.S. Coast Guard Marine Safety Office, San Francisco, and requested to advise on the toxicity of the products involved and safety considerations, and to recommend a strategy to mitigate the impacts of the release. Dimethoate is a sulfur-containing compound with a mercaptin-like odor. Its high molecular weight and low vapor pressure makes it quite stable in solid form at ambient temperatures, and its odor is noticeable even in extremely low concentrations. NOAA hypothesized that some vapor from the solid dimethoate may have leaked into the closed container during shipment, and that it was this vapor that was detected while the vessel was en route to San Francisco. The concentration in the atmosphere within the container was probably never at a toxic level even though it would have been uncomfortable [...]
2. COMMODITY: DIMETHOATE (SOLID).
