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 butyl rubber, minimum 0.4mm thickness), splash-proof chemical goggles, acid vapor respirator with appropriate cartridges, and acid-resistant laboratory coat. Work only under functioning fume hoods with face velocity of 80-120 ft/min. Maintain exposure levels below OSHA PEL of 5 ppm ceiling limit. Ensure proper chemical segregation from oxidizers, bases, and reactive metals. Install emergency eyewash stations and safety showers within 10 seconds travel distance. Follow all laboratory safety protocols for handling mineral acids and maintain proper spill control equipment. Utilize only compatible materials for transfer and storage including borosilicate glass, HDPE, or acid-resistant polymeric containers.
