SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

Personal Protective Equipment (PPE):

Chemical-resistant lab coat
Nitrile or neoprene gloves
Safety goggles or face shield
Dust mask or respirator (if handling large quantities or powder)

Handling:

Handle in a well-ventilated area
Avoid inhalation of dust and contact with skin or eyes
Do not mix with glycerol, alcohols, acids, or organic materials — may cause explosive reactions
Use non-sparking tools and equipment
Wash hands thoroughly after handling

Storage:

Store in tightly sealed containers in a cool, dry, well-ventilated area
Keep away from heat, flammable substances, and reducing agents
Do not store near acids or combustible materials
Clearly label containers and isolate from incompatible chemicals

FIRST AID MEASURES

Inhalation:

Move victim to fresh air
Provide oxygen if breathing is difficult
Seek medical attention if symptoms persist

Skin Contact:

Immediately flush skin with plenty of water for at least 15 minutes
Remove contaminated clothing and shoes
Get medical attention if irritation persists

Eye Contact:

Rinse eyes cautiously with water for at least 15 minutes
Keep eyelids open during rinsing
Seek immediate medical assistance

Ingestion:

Rinse mouth with water (only if conscious)
Do not induce vomiting
Seek emergency medical help immediately
May cause burns to the mouth, throat, and gastrointestinal tract
