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, 0.40 mm thickness).
  • Natural latex or rubber: poor (not recommended) - not suitable for acids.
  • Butyl rubber: good - chemical resistant gloves category III according to EN 374-1:2016.

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.
  • Recommended filter type: ABEK-P3 for vapors/dusts/aerosols.

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.
  • Soak up with inert absorbent material (sand, silica gel, acid binder, universal binder, sawdust).
  • Take up mechanically, placing in appropriate containers for disposal.
  • Never add water directly to concentrated acid spills.
  • Contact emergency services immediately for large spills.
  • Dispose according to local hazardous waste regulations.

Special warnings

  • Contains mercury compounds - extremely toxic, handle with extreme care.
  • Contains chromium(VI) compounds - carcinogenic and mutagenic.
  • Reacts violently with water - always add acid to water, never water to acid.
  • Restricted to professional users only.
  • Store in cool, dry, well-ventilated area away from incompatible materials.
  • Keep away from bases, organic materials, reducing agents, and metals.
