Protective measures

Gloves

  • Viton™: very good - recommended for long-term contact (>480 minutes breakthrough time, 0.70 mm thickness).
  • Nitrile: fair - suitable for short-term contact only (>30 minutes breakthrough time, 0.20 mm thickness).
  • Natural latex or rubber: poor (not recommended) - not suitable for acids.
  • Neoprene: fair to good - moderate resistance to acids.

Safety goggles

  • Always wear chemical safety goggles or face shield when handling this product.
  • Corrective glasses are not considered safety goggles.
  • Handle only in a fume hood or with appropriate exhaust ventilation.

Clothing

  • Wear acid-resistant protective clothing and closed shoes.
  • Long sleeves and full-length pants required.
  • Contact lenses are forbidden while working with this product.
  • Do not wear synthetic clothing that may melt if exposed to acid.
  • Remove contaminated clothing immediately and wash before reuse.

Respiratory protection

  • Ensure adequate ventilation.
  • If exposure limits are exceeded or irritation is experienced, use appropriate respiratory protection.
  • No protective equipment needed under normal use conditions if adequate ventilation is provided.

Spill management

  • Evacuate personnel to safe areas and ensure adequate ventilation.
  • Use full personal protective equipment including acid-resistant gloves and clothing.
  • Prevent entry into drains, sewers, or water bodies.
  • Neutralize carefully with sodium bicarbonate or lime if safe to do so.
  • Absorb with inert material (sand, silica gel, acid binder, universal binder).
  • Collect in appropriate containers for disposal as hazardous waste.
  • Never add water directly to concentrated acid spills.
  • Clean contaminated surfaces thoroughly.
  • Dispose according to local hazardous waste regulations.
