Safety Precautions

CORROSIVE ACID - Professional handling required. Class 8 corrosive liquid requiring proper ventilation systems and secondary containment. Store in temperature-controlled environments below 85°F (29°C). Mandatory PPE includes chemical-resistant gloves (neoprene or rubber, minimum 20 mil thickness), splash-proof chemical goggles, face shield, acid-resistant lab coat or coveralls, and appropriate footwear protection. Work in properly functioning chemical fume hood or ventilated enclosure. Ensure proper chemical segregation from bases and reactive metals. Install emergency eyewash stations and safety showers in handling areas. Follow all OSHA regulations for handling mineral acids and maintain proper pH monitoring systems. Utilize only compatible materials for transfer and storage including glass, HDPE, or appropriate acid-resistant containers and equipment.
