Safety Precautions
Health Hazards:
· Causes serious damage to organs (liver) - the primary occupational hazard.
· Toxic in contact with skin, harmful if inhaled or swallowed.
· Causes skin and eye irritation. May cause an allergic skin reaction.
· Repeated or prolonged skin contact may cause defatting, dryness, cracking, and increase absorption of the toxic substance.
· Suspected of damaging fertility or the unborn child (based on animal evidence).Handling Protection:
· Must wear chemical-resistant gloves (e.g., butyl rubber), safety goggles, and face shield.
· Handle only in a fume hood or with adequate local exhaust ventilation to avoid inhalation of vapors.
· Strictly avoid skin contact. Wear impermeable protective clothing.
· Provide safety shower and eye wash equipment.Storage & Transportation:
· Store in a cool, dry, well-ventilated place.
· Keep container tightly closed to prevent moisture absorption and evaporation.
· Store separately from strong oxidizers, strong acids (e.g., oleum, chlorosulfonic acid), and strong bases (e.g., sodamide) to prevent violent reactions.
· Use carbon steel, stainless steel, or aluminum containers for storage and transport.Fire Fighting:
· Flammable liquid. Flash point 58°C (closed cup).
· Toxic, irritating fumes of nitrogen oxides (NOx) and carbon monoxide (CO) are generated when burning.
· Use water spray, alcohol-resistant foam, dry powder, or CO2 to extinguish fire.
· Firefighters must wear self-contained breathing apparatus (SCBA) and full protective gear.
