Routes of entry: inhalation: yes skin: yes ingestion: yes
reports of carcinogenicity: ntp: no iarc: no osha: no
health hazards acute and chronic: helium is odorless and nontoxic but
may produce suffocation by diluting the concentration of oxygen in
air below level necessary to support life. Extensive tissue damage
or burns can result from expos ure to liquid helium or cold helium
vapors.
explanation of carcinogenicity: helium is a simple asphyxiant and has no
tresho limit value (tlv). Helium not listed as carcinogen by
ntp/iarc/osha.
effects of overexposure: dizziness,nausea,vomiting,loss of
consciousness. Death may result from errors in
judgement,confusion,or loss of consciousness which prevent
self-rescue. At low oxygen concentrations unconsciousness an d
death may occur in seconds without warning.
First aid: assisted respiration and supplemental oxygen should be given
if the victim is not breathing. If cryogenic liquid or cold
boil-off gas contacts a workers skin or eyes, frozen tissues should
be flooded or soaked with tepid water (105-115f; 41-46c) do not
use hot water.Cryogenic burns which result in blistering or deeper
tissue freezing should be seen promptly by a physician.
Hcc: g3
boiling pt: b.P. Text: -452f/268c
vapor density: 32f0.01114
spec gravity: 23f(oc)1atm.138
solubility in water: 68f(20c)1 atm 0.861%
appearance and odor: helium is colorless and odorless in both gaseous
and liquid states.
Stability indicator/materials to avoid: yes
none
stability condition to avoid: none
hazardous decomposition products: none
Waste disposal methods: allow liquid helium to evap in a well-vent
location remote from work areas. Vent helium gas slowly to a
well-vent outdoor location remote for work area.Do not attempt to
dispose of residual helium in compresse gas cylinders.

or osha
