Material Safety Data Sheet
Introduction
Material safety data sheet (MSDS) is a sheet providing detailed information of a specific chemical or chemical mixtures regarding the chemical, physical, and safety properties. It provides detailed safety procedure for safe exposure to chemicals, and is an important component of a safe environment and workplace.
MSDS provides not only the particular substance’s chemical and physical proper-
ties but also instructions and procedures for the chemical to be used properly and safely as well as point out the potential hazards related to a specific substance.

MATERIAL SAFETY DATA SHEET
CHEMICAL NAME
HAZARD IDENTIFICATION
FIRST AID MEASURES
OTHER SAFETY TIPS
Substance Name: Iodine Resublime
Chemical formula: I2
synonyms: Sublimed iodine, crystalline iodin
Chemical Composition: Consists of diatomic iodine molecules (I2I2)
Melting Point: 113.7 degrees Celsius
Boiling Point: 184.3 degrees Celsius
Solubility: Slightly soluble in water, soluble in organic solvents (e.g., alcohol, ether)
Density: ~4.93 grams per cubic centimeter
pH: Not applicable for elemental iodine
Odor: Characteristic sharp, pungent odor
Flash Point: Not applicable (Iodine is not flammable)
Stability and Reactivity: Stable under normal conditions. Reacts with certain metals and compounds; avoid contact with reducing agents.
Other Information: Handle in a well-ventilated area. Wear appropriate protective equipment. Refer to safety data sheets (SDS) for detailed safety information.
Emergency Overview: Resublimed iodine poses hazards such as skin and eye irritation.
Potential health effects:
It may cause respiratory irritation if inhaled and could be harmful if swallowed. Additionally, prolonged or repeated exposure may lead
4. Iodine Resublime
Hazard Identification: toxic
Potential health effects:
It may cause respiratory irritation if inhaled and could be
harmful if swallowed. Additionally, prolonged or repeated
exposure may lead to adverse effects on the thyroid.
First Aid Measure:
skin contact:
Wash affected areas with plenty of water. Remove
contaminated clothing. If irritation persists, seek medical
advice.
5. Other Safety Tips:
Containment:
Quickly contain the spill to prevent further spreading.
Use absorbent materials like vermiculite or spill pads
to soak up the spilled iodine resublime.
6. IODINE SOLUTION
Chemical composition:
Typically refers to a solution
of iodine dissolved in a
solvent such as water or
alcohol.
Its chemical composition can
vary depending on the
concentration and specific
formulation
7. IODINE SOLUTION
Hazard Identification: toxic (used improperly)
Iodine solution is typically a brownish liquid with a strong,
distinctive odor.
Hazards: May cause irritation to the eyes, skin, and respiratory
tract. Ingestion or inhalation of large amounts may lead to
systemic effects.
First Aid Measure:
Eyes: Immediately rinse the affected eye(s) with gently
flowing lukewarm water for at least 15 minutes. Hold the
eyelids open to ensure thorough flushing.
8. Other Safety Tips:
Evacuation: If the spill is large or in a confined
space, evacuate the area to ensure the safety of
personnel.
Isolate the Area: Secure the area to prevent further
contamination.
Ventilation: Ensure proper ventilation to disperse
vapors.
9. IRON (II) SULFATE
Chemical composition:
Iron sulfate, also known as ferrous
sulfate, has the chemical formula
FeSO4. It is composed of iron (Fe)
and sulfate (SO4).
Its chemical composition may vary
depending on its hydration state.
10. IRON (II) SULFATE
Hazard Identification: toxic (if ingested in large amount)
Physical Description: Iron(II) sulfate is a pale green to bluish-green crystalline solid or
granules, depending on the hydration state.
Odor: Generally odorless.
Hazards: May cause eye and skin irritation. Ingestion or inhalation of large amounts may
cause adverse health effects.
First Aid Measure:
Rinse the affected eye(s) gently with plenty of lukewarm water for at least 15
minutes, keeping the eyelid open to ensure thorough flushing.
Remove contact lenses, if present and easy to do, after the first 5 minutes of
rinsing.
11. Other Safety Tips:
Work in a well-ventilated area: Iron Sulfate can release
harmful fumes, so it is important to work in a well-ventilated
area to minimize exposure. If necessary, use a fume hood or
work outdoors.
Protection:
Wear appropriate personal protective equipment (PPE):
Chemical-resistant gloves
Safety goggles or a face shield
Lab coat or chemical-resistant apron
Boots or shoe covers, if necessary
12. IRON FILING
Chemical composition:
Iron filings are composed of
pure iron (Fe) in the form of
small, thin, and elongated
metal shaving or particles.
They are usually obtained by
filing or grinding a piece of
iron or iron alloy.
13. IRON FILLINGS
Hazard Identification: toxic (if ingesting large amount)
Physical Description: Iron fillings are small pieces or shavings of elemental iron,
typically in the form of fine particles or filings.
Odor: Generally odorless.
Hazards: While iron fillings are generally considered low hazard, they may cause
physical harm if mishandled or ingested in large quantities.
First Aid Measure:
Eye Contact:
Immediate Action:
Rinse the affected eye(s) gently with plenty of lukewarm water for at least 15
minutes. Keep the eyelid open to ensure thorough flushing.
If the person wears contact lenses, ensure they are removed during the rinsing
process, but do not delay rinsing to do so.
14. Other Safety Tips:
Containment:
Quickly contain the spill to prevent further spreading.
Use barriers like absorbent materials (sand, vermiculite) to
confine the iron filings.
Isolation:
Isolate the affected area to minimize exposure to personnel.
Restrict access to the spill zone.
15. Laboratory Safety Plan:
1. General Laboratory Information:
