conscious persons sh ould be assisted to an uncontaminated area and
inhale fresh air. Quick removal from contaminated area is most
important. Unconscious persons should be moved to an uncontaminated
area, given assisted r espiration and supplemental oxygen. Further
treatment should be symptomatic and supportive.

health hazards acute and chronic: the most significant hazard associated
with this gas is inhalation of oxygen-deficient atmospheres.
symptoms of oxygen deficiency include respiratory difficulty,
ringing i ears, headache, dizziness, i ndigestion, nausea, &
possible death. Contact with liquid or rapidly expanding gases
(which are released under high pressure) may cause frostbite. There
are no known adverse health effects associated with chronic
exposure to this gas. Target organs: respiratory system.
effects of overexposure: headaches, ringing in the ears,dizziness,
drowsiness, unconsciousness, nausea, vomiting & depression of all
the senses.
medical cond aggravated by exposure: preexisting respiratory conditions.
First aid: remove to fresh air as quickly as possible. In case of
contact immediately flush eyes with copious amounts of water for at
least 15 minutes. If not breathing give artificial respiration. If
breathing is difficult, give oxygen. Only trainedpersonnel should
administer oxygen. In case of frostbite, place frostbitten part in
warm water. Do not use hot water. If warm water is not available,
wrap parts gently in blankets. Alternatively, if fingers or hands
are frostbitten, place in armpit. Encourage victim to gently
exercise part while being warmed. Seek immediate medical attention.

appearance and odor: sulfur hexafluoride is a colorless, odorless gas.

non-reactive with most chemicals but can react violently with disilane.
if decomposition occurs in presence of oxygen at high temperatures,
thionyl fluoride compounds can be generated.
stability condition to avoid: contacts with incompatible materials.
cylinders exposed to high temperatures or direct flame can rupture
or burst.
hazardous decomposition products: sulfur hexafluoride is only stable at
elevated temperatures (>400f) when contained in aluminum, stainless
steel, copper, brass or silver. Other materials can cause slow
decomposition to sulfur-fluoride.
Waste disposal methods: dispose of in accordance with local, state &
federal regulations. Return cylinders with any residual product to
airgas inc. Do not dispose of locally.

cyanosis (blue skin). Ingestion: not applicable (g as at normal
conditions). Delayed effects: none known.

sensitiveness to strong light) persists. Inhalation-immediately
remove to fresh air. If bre athing has stopped, give artificial
respiration. If breathing is difficult, give oxygen provided a
qualified operator is available. Contact a physician.
