Safety & Handling

Hazard Statements:

• May cause respiratory irritation

• Flammable solid

• Harmful if swallowed

• Causes mild skin and eye irritation

Precautionary Measures:

• Keep away from ignition sources such as heat, sparks, or open flames

• Use non-sparking tools and explosion-proof equipment

• Store in tightly sealed containers under dry, well-ventilated conditions

• Wear appropriate PPE including gloves, goggles, and protective clothing

• Avoid inhalation and ingestion; do not eat, drink, or smoke during handling

• Wash hands thoroughly after use

First Aid Measures:

• Eye Contact: Rinse carefully with water; remove contact lenses if easy to do

• Skin Contact: Wash immediately with water; remove contaminated clothing

• Ingestion: Rinse mouth; do not induce vomiting

• Inhalation: Move to fresh air and seek medical attention if needed

Disposal Guidelines

For small quantities, allow controlled evaporation in a safe, open area. Larger volumes should be incinerated using a chemical incinerator equipped with proper scrubbers and burners. If evaporation or incineration is not feasible, collect the waste in dedicated solvent drums for disposal by a certified hazardous waste management service.
