Lead Chloride Anhydrous Extra Pure

Whatsapp Order

Lead Chloride (Anhydrous) Extra Pure is a white crystalline compound with the chemical formula PbCl₂, offered in its high-purity, moisture-free form for specialized applications. It is only sparingly soluble in cold water but dissolves more readily in hot water, forming a clear solution upon heating. This compound is used in laboratory synthesis, particularly in the preparation of other lead-based reagents, and plays a role in ceramic glazing, pigment production, and electrochemical processes. In research, it is also employed in photographic materials, optical devices, and inorganic analysis. Due to the toxic nature of lead compounds, strict safety protocols are necessary during storage and handling.

SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

Personal Protective Equipment (PPE):

Wear lab coat, chemical-resistant gloves (e.g., nitrile or neoprene), and safety goggles.
Use a NIOSH-approved respirator if dust or fumes are present.
Always work in a fume hood or well-ventilated area.

Handling:

Handle with extreme care—toxic if inhaled or ingested.
Avoid creating dust or aerosols.
Prevent contact with eyes, skin, and clothing.
Wash hands thoroughly after use.
Avoid contamination of surfaces and personal items.

Storage:

Store in a tightly closed container, in a cool, dry, well-ventilated area.
Keep away from acids, moisture, and incompatible materials.
Store labeled as Toxic and restrict access to authorized personnel only.

FIRST AID MEASURES

Inhalation:

Remove person to fresh air immediately.
Seek medical attention if respiratory symptoms (e.g., coughing, difficulty breathing) occur.
Provide oxygen or artificial respiration if needed.

Skin Contact:

Remove contaminated clothing.
Wash skin with plenty of soap and water for at least 15 minutes.
Seek medical advice if irritation or symptoms persist.

Eye Contact:

Rinse eyes cautiously with water for at least 15 minutes.
Remove contact lenses if present and easy to do.
Continue rinsing and seek immediate medical attention.

Ingestion:

Rinse mouth with water.
Do NOT induce vomiting.
Get urgent medical attention—lead salts are highly toxic if swallowed.

FIRE FIGHTING MEASURES

Flammability:

Non-flammable, but may emit toxic fumes if heated.

Extinguishing Media:

Use dry chemical, foam, or CO₂.
Water spray may be used to cool surfaces but avoid water runoff contamination.

Hazardous Combustion Products:

May release toxic lead oxides and chlorine-containing gases.

Firefighter Protection:

Wear self-contained breathing apparatus (SCBA) and full protective gear.
Avoid inhalation of combustion products.
