Safety Precautions

HIGHLY CORROSIVE - Professional handling required. Class 8 corrosive liquid requiring comprehensive containment systems and exposure controls. Store in temperature-controlled environments below 100°F (38°C). Mandatory PPE includes chemical-resistant gloves (neoprene or rubber, minimum 30 mil thickness), full face shield over chemical splash goggles, chemical-resistant suit or coveralls, and rubber boots. Ensure proper chemical segregation from acids and reactive metals. Install emergency safety showers and eyewash stations in all handling areas. Follow all OSHA regulations for handling strong bases and maintain proper pH monitoring systems. Utilize only compatible materials for transfer and storage equipment including steel, nickel alloys, or appropriate FRP containers and piping systems. Heat tracing and insulation required for outdoor storage and transfer lines.
