Carbon Dioxide Reporting Exemption

Posted October 18, 2004. Comments may be submitted through November 18, 2004 via the 'Contact Us' link.

Pursuant to California Health and Safety Code section 25503.5(c)(2), Unified Program agencies in Santa Clara County, consisting of the Santa Clara county fire department hazardous materials programs and the County Environmental Health Department (also defined as Administering Agencies) have determined that carbon dioxide, used for the dispensing of food or beverage, is exempt from reporting on a Hazardous Materials Business Plan in quantities less than 6,000 cubic feet. This statement constitutes the required public notice.

Rationale: Establishments that dispense food and beverages are known by the public and by emergency response personnel to routinely have sources of carbon dioxide for the dispensing of food and beverages. Preparation of a Hazardous Materials Business Plan to alert the community or emergency responders is unnecessary and would not significantly enhance emergency response activities. The California Fire Code permit threshold for carbon dioxide is 6,000 cubic feet, thirty times greater than the reporting threshold for a Hazardous Materials Business Plan. The primary hazard of carbon dioxide is as a simple asphyxiant. With respect to carbon dioxide dewars, a catastrophic release from a dewar is unlikely as the sudden

release of the gas would result in condensation freezing and restricting the rate of release.

Note:   This exemption applies to Hazardous Materials Business Plan reporting only.   Requirements for storage and use still apply. Below is a summary of these requirements.
