What hazmat class is chlorine?

4-Digit DOT Placards: Hazard Class 2 – 1017 (Chlorine)

Is chlorine gas an asphyxiant?

Acts as an asphyxiant at high concentrations. Inhalation of high concentrations (e.g, greater than 15 ppm) causes choking, coughing, burning of the throat, and severe irritation of the upper respiratory tract; additionally, pulmonary edema, bronchitis, and pneumonitis may result.

Is chlorine gas toxic?

Gaseous chlorine is poisonous and classified as a pulmonary irritant. It has intermediate water solubility with the capability of causing acute damage to the upper and lower respiratory tract. Chlorine gas has many industrial uses, but it was also once used as a chemical weapon in World War I.

How painful is death by chlorine gas?

At 5–15 ppm, there is moderate mucous membrane irritation. At 30 ppm and beyond, there is immediate chest pain, shortness of breath, and cough. At approximately 40–60 ppm, a toxic pneumonitis and/or acute pulmonary edema can develop.

Is chlorine considered a hazardous material?

Chlorine is a common hazardous material found in most communities in the United States as a gas or in compound with other chemicals that can release the chlorine when in contact with water or other chemicals.

How toxic is chlorine gas?

Toxicity to chlorine gas depends on the dose and duration of exposure. At concentrations of 1 to 3 ppm, chlorine gas acts as an eye and oral mucous membrane irritant; at 15 ppm, there is an onset of pulmonary symptoms, and it can be fatal at 430 ppm within 30 minutes.

Is pool chlorine a hazardous material?

Many chemicals used at swimming pools may release chlorine – an extremely hazardous substance (EHS). EPA stresses that although mishandling of these chemicals can cause harm, there is no cause for undue alarm about their presence in the community.

How much chlorine gas is lethal?

Concentrations of about 400 ppm and beyond are generally fatal over 30 minutes, and at 1,000 ppm and above, fatality ensues within only a few minutes. A spectrum of clinical findings may be present in those exposed to high levels of chlorine.

How long does chlorine gas stay in the air?

It depends on the wind and weather. ANY release of chlorine gas should be reported to emergency services. When treated effluent is released into receiving waters, free residual chlorine dissipates rapidly (it has a half-life of 1.3 to 5 hours).

What neutralizes chlorine gas?

Chlorine in a swimming pool is most commonly reduced or neutralized by adding sodium thiosulfate (Na2S2O3) to the pool water.
