How do I plot a protective action distance for a spill?
To plot a protective action distance, first specify a location and wind direction below. Once a distance is plotted, you can drag the spill or right click the map to move the spill to a new location. Select the direction of the wind at your location. Is the material involved in a fire?

Result: For large spill entries, representative release quantities for Hazard Zone A gases are typically much lower than for materials authorized for bulk transportation
What is the boiling point of chlorine?
Not applicable, because chlorine is a gas above its boiling point of 93.2°F (34°C). In the event of a poison emergency, call the poison center immediately at 1-800-222-1222.

What term does the ERG use for the distance from a spill or leak that all persons should be evacuated in all directions?
After determining the hazardous material(s) involved in the incident, responders must determine how closely they may approach a spill. The ERG2008 defines the “Initial Isolation Distance” as: “a distance within which all persons should be considered for evacuation in all directions from the actual spill/leak source.

How long does it take for respiratory symptoms to resolve after exposure to chlorine?
TIME COURSE: Respiratory symptoms may be immediate or delayed for several hours or days after exposure to chlorine. Symptoms generally resolve within 6 hours after mild exposures, but may continue for several days after severe exposures. Deterioration may continue for several hours.
What are the dangers of chlorine?
In water, it forms hydrochloric acid (HCl) and hypochlorous acid (ClHO). Chlorine attacks plastic, rubber, coatings, and many metals in the presence of water.
What is chlorine used for?
It is widely used as bleach in the manufacture of paper and cloth and in manufacturing solvents, pesticides, synthetic rubber, and refrigerants. Chlorine has also been used as a chemical warfare choking agent.

How long does it take for a person to recover from exposure to chlorine?
DELAYED EFFECTS OF EXPOSURE: For previously healthy individuals with an acute exposure to chlorine, pulmonary function usually returns to pre-exposure levels within 7 to 14 days. Individuals who survive a single, acute exposure usually have no long-term adverse health effects, although persistent effects have been reported. For example, exposure to chlorine may cause reactive airways dysfunction syndrome (RADS), a chemical irritant-induced type of asthma. For exposed individuals who have underlying cardiopulmonary disease or for those who suffer complications (for example, pneumonia) during therapy, the risk for developing chronic airway inflammation is increased.

Is cyanogen chloride a chemical?
DESCRIPTION: Cyanogen chloride (CK) is a highly volatile and toxic chemical asphyxiant that interferes with the body’s ability to use oxygen. Exposure to cyanogen chloride (CK) can be rapidly fatal. It has whole-body (systemic) effects, particularly affecting those organ systems most sensitive to low oxygen levels: the central nervous system (brain), the cardiovascular system (heart and blood vessels), and the pulmonary system (lungs). Cyanogen chloride (CK) has strong irritant and choking effects. Its vapors are extremely irritating and corrosive. Cyanogen chloride (CK) is a chemical warfare agent (military designation CK). It is used commercially in chemical synthesis and fumigation.
