EDMG 240 Final Exam
UN 1076 – Phosgene
HAZARDS:
Phosgene is a highly toxic, irritating and corrosive gas. Inhalation can cause fatal respiratory damage. Phosgene reacts violently and decomposes to toxic compounds on contact with moisture, including chlorine, carbon monoxide and carbon tetrachloride.
In case of skin contact: If liquid phosgene (below 8.2 deg C) contacts the skin or clothing, an inhalation exposure should be suspected. Hazards due to skin contact with the gas is unknown. Phosgene does, however, react slowly with moisture to form hydrochloric acid, which can be irritating. Flush with water for at least 15 minutes and seek medical attention as necessary. Take first aid for inhalation exposures as well.
In case of eye contact: Phosgene reacts slowly with the moisture in the eye to form hydrochloric acid, which can cause severe irritation and burns. Immediately flush the contaminated eye(s) with water for at least 15 minutes. Seek medical attention immediately.
In case of inhalation: Phosgene can cause severe irritation to the respiratory tract, resulting in burning throat, nausea, vomiting, chest pain, shortness of breath and headache. Severe respiratory distress may not develop for 4 to 72 hours after exposure, at which point pulmonary edema (fluid in lungs) progressing to pneumonia and cardiac faultier may occur.
Move to fresh air and seek medical attention immediately.
In case of ingestion: Not a likely route of exposure since phosgene is a gas at room temperature.
FIRE AND EXPLOSION HAZARDS: Nonflammable.
PPE:
ENGINEERING CONTROLS:
Use a laboratory hood with forced ventilation for handling small quantities. Use local exhaust to prevent accumulation above the exposure limits.
EYE/FACE PROTECTION:
Gas tight chemical goggles or full-face piece respirator.
SKIN PROTECTION:
Rubber or Teflon ® protective gloves.
RESPIRATORY PROTECTION:
Positive pressure air line with full-face mask and escape bottle or self-contained breathing apparatus should be available for
