SECTION 4. FIRST AID MEASURES
Inhalation: Immediately call a poison center or doctor. Effects of exposure (inhalation) to substance may be delayed.
Move victim to fresh air. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is
difficult. Keep victim warm and quiet. Treat symptomatically and supportively. Ensure that medical
personnel are aware of the material(s) involved and take precautions to protect themselves.
Skin contact: For severe burns, immediate medical attention is required. Immediately call a poison center or doctor.
Remove and wash contaminated clothing before re-use. In case of contact with substance, immediately
flush skin with running water for at least 20 minutes. Treat symptomatically and supportively. Ensure that
medical personnel are aware of the material(s) involved and take precautions to protect themselves.
Eye contact: IMMEDIATELY flush eyes with running water for at least 15 minutes, keeping eyelids open. Eye contact
with vapors or substance may cause severe injury, burns, or death. Call emergency medical service. Move
victim to fresh air. Check for and remove any contact lenses. Keep victim warm and quiet. Treat
symptomatically and supportively. Effects of exposure to substance may be delayed. Ensure that medical
personnel are aware of the material(s) involved and take precautions to protect themselves.
Ingestion: Do not induce vomiting with out medical advice. Call a physician or Poison Control Center immediately. Do
not use mouth-to-mouth method if victim ingested the substance; give artificial respiration with the aid of a
pocket mask equipped with a one-way valve or other proper respiratory medical device. Loosen tight
clothing such as a collar, tie, belt or waistband. If a person vomits place them in the recovery position so
that vomit will not reenter the mouth and throat. Rinse mouth. Keep victim warm and quiet. Treat
symptomatically and supportively. Ensure that medical personnel are aware of the material(s) involved and
take precautions to protect themselves.
Symptoms/effects:
Acute: Pain. Redness.
Delayed: No data available
Immediate medical attention: WARNING: It might be hazardous to the person providing aid to give mouth-to-mouth respiration, because
the inhaled material is corrosive. For severe burns, immediate medical attention is required. If breathing
has stopped, perform artificial respiration. Use first aid treatment according to the nature of the injury.
Ensure that medical personnel are aware of the material(s) involved and take precautions to protect
themselves.
SECTION 5. FIREFIGHTING MEASURES
Suitable extinguishing media: Dry chemical, CO2 or water spray. Consult with local fire authorities before attempting large scale fire
fighting operations.
Specific hazards arising from the chemical
Hazardous combustion products: These products include: Carbon oxides Halogenated compounds Silicates
Other specific hazards: WARNING: Highly toxic HF gas is produced during combustion.
Special precautions for fire-fighters:
Use water spray or fog; do not use straight streams. Dike fire-control water for later disposal; do not scatter the material. Containers may explode when
heated. Move containers from fire area if you can do it without risk.
Special protective equipment for fire-fighters:
Wear positive pressure self-contained breathing apparatus (SCBA). Structural fire fighters' protective clothing provides limited protection in fire situations
ONLY; it may not be effective in spill situations. Wear chemical protective clothing which is specifically recommended by the manufacturer. It may
provide little or no thermal protection.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal precautions: Avoid contact with skin, eyes, and clothing. Keep people away from and upwind of spill/leak. Do not touch
damaged containers or spilled material unless wearing appropriate protective clothing (Section 8). Warn
unnecessary personnel to move away. Stop leak if you can do it without risk. Ensure adequate ventilation.
Isolate the hazard area and deny entry to unnecessary and unprotected personnel.
Personal protective equipment: Wear eye protection (splash goggles) and face protection (full length face shield). Lab coat. Dust
respirator. Be sure to use a MSHA/NIOSH approved respirator or equivalent. Wear protective gloves
(nitrile).
Emergency procedures: Prevent dust cloud. In case of a spill and/or a leak, always shut off any sources of ignition, ventilate the
area, and excercise caution. Do not touch damaged containers or spilled material unless wearing
appropriate protective clothing. Warn personnel to move away. Prevent entry into sewers, basements or
confined areas; dike if needed.
Methods and materials for containment and cleaning up:
ELIMINATE all ignition sources (no smoking, flares, sparks, or flames in immediate area). Stop leak if without risk. Ventilate the area. Absorb with an
inert material and put the spilled material in an appropriate waste disposal container. Use clean non-sparking tools to collect absorbed material.
Environmental precautions:
Prevent further leakage or spillage if safe to do so. Water runoff can cause environmental damage. Prevent entry into sewers, basements or confined
areas; dike if needed.
SECTION 7. HANDLING AND STORAGE
Precautions for safe handling: Avoid inhalation of vapor or mist. Manipulate under an adequate fume hood. Avoid contact with skin and
eyes. Good general ventilation should be sufficient to control airborne levels. Keep container dry. Handle
and open container with care. Wear suitable protective clothing, gloves and eye/face protection. When
using do not eat, drink, or smoke. Keep away from sources of ignition.
Conditions for safe storage: Store locked up. Keep containers tightly closed in a cool, well-ventilated place. Keep away from
incompatibles. Containers which are opened must be carefully resealed and kept upright to prevent
leakage. Avoid prolonged storage periods. Store under inert gas (e.g. Argon). Hygroscopic material, store
in a tightly sealed container. Store in refrigerator.
Storage incompatibilities: Bases, Store away from oxidizing agents
SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Exposure limits: No data available
Appropriate engineering controls:
Good general ventilation should be sufficient to control airborne levels. Ventilation is normally required when handling or using this product. Eyewash

The number of electrons in each of lanthanum's shells is [2, 8, 18, 18, 9, 2] and its electron configuration is [Xe] 5d1 6s2. The lanthanum atom has a radius of 187 pm and a Van der Waals radius of 240 pm. Lanthanum was first discovered by Carl Mosander in 1838. In its elemental form, lanthanum has a silvery white appearance.
It is a soft, malleable, and ductile metal that oxidizes easily in air. Lanthanum is the first element in the 
The number of electrons in each of Sulfur's shells is 2, 8, 6 and its electron configuration is [Ne] 3s2 3p4. In its elemental form, sulfur has a light yellow appearance. The sulfur atom has a covalent radius of 105 pm and a Van der Waals radius of 180 pm. In nature, sulfur can be found in hot springs, meteorites, volcanoes, and as galena, gypsum, and epsom salts. Sulfur has been known since ancient times but was not accepted as an element until 1777, when Antoine Lavoisier helped to convince the scientific community that it was an element and not a compound.
