Potential Health Effects
----------------------------------
Inhalation:Corrosive. Vapors severely irritate and can burn the mucous
membranes and respiratory tract. Excessive tears, rhinitis, tightness in the
chest, sore throat, headache and delayed pulmonary edema can result. Inhalation
of concentrated vapors may be fatal.
Ingestion:Corrosive. Can cause severe burns of the mouth, throat and
stomach. Causes abdominal pain, diarrhea, fever, vomiting, stupor and shock.
Probable lethal dose is 2 to 4 gm of free iodine.
Skin Contact: Corrosive. Liquid contact may cause blistering burns,
irritation, and pain. Vapors may be severely irritating to the skin.
Eye Contact:Corrosive! Vapors are severely irritating and may cause
damage to the eyes. Contact may cause severe burns and permanent eye damage.
Chronic Exposure:Chronic exposure to iodine may cause insomnia,
conjunctivitis, inflammation of the nasal mucous, bronchitis, tremor, rapid
heart beat, diarrhea and weight loss. Allergic sensitization may occur.
Aggravation of Pre-existing Conditions:Persons with pre-existing skin
disorders, eye problems, impaired respiratory function, or disease of the
thyroid, lungs, or kidney may be more susceptible to the effects of the
substance.
Inhalation:Remove
to fresh air. If not breathing, give artificial respiration. If breathing is
difficult, give oxygen. Get medical attention immediately. Observe for the
development of pulmonary edema.
Ingestion:Induce vomiting immediately as directed by medical personnel.
Never give anything by mouth to an unconscious person. Get medical attention
immediately.
Skin Contact:Wipe off excess material from skin then immediately flush
skin with plenty of water for at least 15 minutes while removing contaminated
clothing and shoes. Get medical attention immediately. Wash clothing before
reuse. Thoroughly clean shoes before reuse. Iodine stains can be removed by
immediately washing skin with 5% sodium thiosulfate solution.
Eye Contact:Immediately flush eyes with plenty of water for at least 15
minutes, lifting lower and upper eyelids occasionally. Get medical attention
immediately.
Fire:Not
combustible, but substance is a strong oxidizer and its heat of reaction with
reducing agents or combustibles may cause ignition.
Explosion:Contact with oxidizable substances and incompatibles may cause
extremely violent combustion.
Fire Extinguishing Media:Use any means suitable for extinguishing
surrounding fire. Water spray may be used to keep fire exposed containers cool.
Special Information:In the event of a fire, wear full protective clothing
and NIOSH-approved self-contained breathing apparatus with full facepiece
operated in the pressure demand or other positive pressure mode.
Notify
safety personnel of iodine spill or leaks. Ventilate area of leak or spill. Wear
protective equipment as specified in Sect. 8. Isolate hazard area. Keep
unnecessary and unprotected personnel from entering. Collect and containerize as
much solid iodine as possible. Cover the spill area with an excess of reducing
agent (sodium thiosulfate, bisulfate, or ferrous salts in 3M sulfuric acid) and
then neutralize with soda ash. Collect slurry into approved containers.
Keep
in a tightly closed container. Store in a cool, dry, ventilated area away from
sources of heat or ignition. Protect against physical damage. Store separately
from reactive or combustible materials, and out of direct sunlight. Containers
of this material may be hazardous when empty since they retain product residues
(dust, solids); observe all warnings and precautions listed for the product.
Airborne
Exposure Limits:
-OSHA Permissible Exposure Limit (PEL):
0.1 ppm Ceiling
-ACGIH Threshold Limit Value (TLV):
0.01 ppm (TWA) inhalable fraction and vapor for Iodine and Iodides.
0.1 ppm (STEL) vapor and aerosol for Iodine.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee
exposures below the Airborne Exposure Limits. Local exhaust ventilation is
generally preferred because it can control the emissions of the contaminant at
its source, preventing dispersion of it into the general work area. Please refer
to the ACGIH document, Industrial Ventilation, A Manual of Recommended
Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded and engineering controls are not feasible,
wear a supplied air, full-facepiece respirator, airlined hood, or full-facepiece
self-contained breathing apparatus. Breathing air quality must meet the
requirements of the OSHA respiratory protection standard (29CFR1910.134). This
substance has unknown warning properties.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or
coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is
possible. Maintain eye wash fountain and quick-drench facilities in work area.
