Safety Precautions

CORROSIVE MATERIAL - Professional handling required. Class 8 corrosive liquid requiring comprehensive ventilation systems and exposure monitoring. Store in cool, well-ventilated areas below 77°F (25°C). Mandatory PPE includes chemical-resistant gloves (neoprene or rubber, minimum 0.4mm thickness), splash-proof chemical goggles, face shield, acid vapor respirator with appropriate cartridges, and acid-resistant protective clothing. Work only in properly ventilated areas with local exhaust systems. Maintain exposure levels below OSHA PEL of 1 mg/m³ TWA. Ensure proper chemical segregation from bases, reducing agents, and reactive metals. Install emergency eyewash stations and safety showers in handling areas. Follow all industrial safety protocols for handling strong mineral acids and maintain proper spill control equipment. Utilize only compatible materials for transfer and storage including HDPE, PTFE-lined, or acid-resistant containers.
