| 1Two threatened and 105 actual ammonia releases. 2A release may be reported in pounds or in gallons, not both. For spills reported in gallons, the median was 18 gallons and the average was 128 gallons. For spills reported in pounds, the median was 202 pounds and the average was 530 pounds. 3This number is a minimum count. For some events, no data were recorded because the evacuation time or the number of evacuated persons were unknown and could not be estimated from available information. 4Person-hours is calculated by multiplying the number of persons evacuated by the length of the evacuation for each event, and summing the results for all events.http://www.health.state.ny.us/environmental/chemicals/hsees/ammonia.htm | |||||||
