HEALTH & SAFETY INFORMATION
• IDLH:
100
mg[Sn]/m3 as inorganic tin
•
OSHA Table Z-1 Air Contaminant as tin
•
The U. S. Department of Health and Human Services, the International Agency for
Research on Cancer (IARC), and the EPA have not classified metallic tin or
inorganic tin compounds for carcinogenicity.
•
Corrosive to the eyes, skin, and respiratory tract. Inhalation of aerosols and
fume may cause lung edema; the effects may be delayed. Chronic exposure may
affect the lungs. Human and animal studies show that ingestion of large amounts
of inorganic tin compounds can cause stomach aches, anemia, and liver and
kidney problems.
Exposure Limits:
•
ACGIH TLV: 2 mg/m3 TWA
•
OSHA PEL/NIOSH REL: 2 mg/m3 TWA
Respirator:
10
mg/m3:
DM (any dust and mist
respirator).
20
mg/m3:
DMXSQ (any dust and
mist respirator except single-use and quarter mask respirators) SA (any
supplied-air respirator).
50
mg/m3
: SA:CF (any
supplied-air respirator operated in a continuous-flow mode) PAPRDM (any
powered, air-purifying respirator with a dust and mist filter).
100 mg/m3:
HiEF (any air-purifying, full-facepiece
respirator with a high-efficiency particulate filter) SCBAF (any self-contained
breathing apparatus with a full facepiece) SAF (any supplied-air respirator
with a full facepiece).
Emergency
or Planned Entry into Unknown Concentrations or IDLH Conditions
SCBAF:PD,PP (any self-contained breathing
apparatus that has a full facepiece and is operated in a pressuredemand or
other positive-pressure mode) SAF:PD,PP:ASCBA (any supplied-air respirator that
has a full facepiece and is operated in a pressuredemand or other
positive-pressure mode in combination with an auxiliary self-contained
breathing apparatus operated in a pressure-demand or other positive-pressure
mode).
Escape:
HiEF
(any airpurifying, full-facepiece respirator with a highefficiency particulate
filter) SCBAE (any appropriate escape-type, self-contained breathing
apparatus).
Reactivity:
A
strong reducing agent; reacts violently with oxidizers, bromine trifluoride,
hydrogenperoxide, metal nitrates, potassium, and sodium. Reacts with oxygen in
air forming tin oxydichloride, which is insoluble in water. Emits toxic
chlorides when heated to decomposition.
FIRE INFORMATION
If
material or contaminated runoff enters waterways, notify downstream users of
potentially contaminated water.
FIRST AID:
Eye:
If this chemical contacts
the eyes, immediately wash them with large amounts of water, occasionally
lifting the lower and upper lids. Get medical attention immediately. Contact
lenses should not be worn when working with this chemical.
Skin:
If this chemical contacts the skin,
immediately wash the contaminated skin with soap and water. If this chemical
penetrates the clothing, immediately remove clothing, wash the skin with soap
and water, and get medical attention promptly.
Inhalation:
If a person breathes large amounts of this
chemical, move exposed person to fresh air at once. If breathing has stopped,
perform mouth-to-mouth resuscitation. Keep the affected person warm and at
rest. Get medical attention as soon as possible.
Ingested:
If this chemical has been swallowed, get
medical attention immediately.
