Technical Guidance for Hazard Analyses
A hazard analysis must be completed for each facility reporting the presence of one or more Extremely Hazardous Substances (EHSs) above the established threshold planning quantity (TPQ). Facilities requiring a site-specific hazard analysis are listed as an attachment to the contract between the State of Florida and the recipient. The data that is required to be included in each facility's hazard analysis is explicitly stated in the Scope of Work of the contract; items listed in the Scope of Work follow with discussion where appropriate for clarification or emphasis.
Technical assistance for CAMEO is provided by Gary Hilbert. His toll free telephone number is 1-800-992-2636 or E-mail address is cameo@cameosupport.com .
Facility Information
Facility name and physical address: A Post Office Box does not indicate physical location and thus is not acceptable; similarly, greater detail than a highway name (e.g., "State Road 20 North") must be provided in order that responders may locate the facility. Mailing addresses will generally be included for the parent company or owner/operator in the appropriate section of the report.
Facility Emergency Coordinator: Provide the name, title and telephone number (day and 24-hour) of the designated facility coordinator.
This individual is the facility representative who should be contacted in the event of an emergency.
Transportation Routes: List the main routes used to transport chemicals to the facility.
Indicate the mode of transportation if other than road delivery (rail line, air etc.). It is understood that road deliveries of chemicals may vary based upon delivery schedules and other factors; simply list those possible road segments from the county line and in the immediate vicinity of the facility. Statements such as "local and state highways" and "route varies with carrier/driver" are not acceptable.
Evacuation routes: Based on wind direction (North, South, East, West), identify the route(s) downwind to exit the vulnerable zone.
In determining evacuation routes, consider local road system characteristics and traffic flow patterns, road capacities and connections to primary roads where appropriate. The goal of this process is to ensure that routes away from the path of the chemical plume are pre-identified for the most likely and worst-case scenario.
Facility Identification: SERC code and geographic coordinates.
The SERC code is the bottom number next to the facility name on the contract attachment that lists the facilities for which a hazard analysis must be performed. Geographic coordinates should be indicated in latitude/longitude format.
Hazard Identification
Provide the following information for each EHS above the TPQ at the facility:
Chemical Identity: Provide proper chemical name, Chemical Abstract Service (CAS) number, and natural physical state of each EHS.
Depending on its application at a particular facility, a chemical's natural physical state (NPS) may or may not be the same as its actual physical state (APS). For example, formaldehyde's NPS is gas, but it is always found as a liquid. Be sure to list the chemical's NPS and use that state when performing vulnerable zone (VZ) calculations.
Maximum Quantity On-Site: Express in pounds the maximum quantity of each EHS the facility would have on-site at any given time.
EHS quantities are not to be expressed in gallons, liters or other measures. Be sure that the maximum quantity indicated is consistent throughout the report. If other EHSs are present below TPQ, it is not necessary to indicate their amounts as well; however, this additional information may prove helpful to emergency responders.
Amount in Largest Vessel or Interconnected Vessels: Express in pounds the amount of each EHS stored in the largest vessel or interconnected vessels.
This is the number of pounds used as the release amount. Ensure that this amount is not greater than the maximum quantity on site.
Type and Design of Chemical Container: Indicate the storage method for each EHS, i.e., drum, cylinder, tank etc.
Additional options include above-ground tank, below-ground tank, tank inside building, steel drum, plastic or nonmetallic drum, can, carboy, silo, fiber drum, bag, box, glass bottles or jugs, plastic bottles or jugs, tote bin, tank wagon, rail car, other.
Nature of the Hazard: Describe the type of hazard most likely to accompany a spill or release of each EHS, i.e., fire, explosion.
Additional options include reactive, acute and chronic.
Vulnerability Analysis
Extent of the Vulnerable Zone(s): Identify the estimated geographical area(s) that may be subject to airborne concentrations of an EHS at levels that could cause irreversible acute health effects or death to human populations within the area following an accidental release.
Each VZ should be clearly plotted on an appropriate map(s) of the area surrounding the facility. The facility name, SERC code, chemical name and radius shall be noted on the map(s).
Critical Facilities: List facilities within the vulnerable zone which are essential to emergency response or house special needs populations, i.e., schools, public safety facilities, hospitals, etc., and the maximum expected occupancy for each one.
If none, note “none”.
Estimated Exposed Population: Provide an estimate of the total population within the vulnerable zone that would be affected in a worst case release.
Total exposed population includes facility employees, general population and critical facility populations. Various population estimation methodologies may result in over count or under count of VZ populations. Care should be used in ensuring that the VZ population estimates are accurate.
Risk Analysis
Probability of Release: Rate the probability of release as Low, Moderate or High based on observations at the facility.
Considerations should include history of previous incidents and current conditions and controls at the facility.
Severity of Consequences of Human Injury: Rate the severity of consequence if an actual release were to occur.
Rate the severity of consequences as Low, Moderate, or High based on the appropriate technical considerations.
Severity of Consequences of Damage to Property: Rate the potential damage to the facility, nearby buildings and infrastructure if an actual release were to occur.
Rate the severity of consequences as Low, Moderate, or High based on the appropriate technical considerations.
Severity of Consequences of Environmental Exposure: Rate the potential damage to the surrounding environmentally sensitive areas, natural habitat and wildlife if an actual release were to occur.
Rate the severity of consequences as Low, Moderate, or High based on the appropriate technical considerations.
Historical Accident Record: Describe any past releases or incidents that have occurred at the facility.
If none have occurred, note "none."
