Safety Precautions

CORROSIVE MATERIAL - Requires professional handling protocols with strict safety management. This concentrated acid demands comprehensive protective measures, including dedicated ventilation systems, secondary containment strategies, and rigorous personal protective equipment requirements.

Storage must be conducted in temperature-controlled environments between 40-85°F, utilizing acid-resistant containers constructed from materials like glass, HDPE, or specialized chemical-resistant polymers. Implement strict segregation from incompatible chemical classes, particularly bases, reactive metals, and organic compounds to prevent potentially dangerous chemical interactions.

Mandatory personal protective equipment includes chemical-resistant gloves (minimum 20 mil neoprene or rubber), splash-proof chemical goggles, full-face shield, acid-resistant laboratory coat, and appropriate closed-toe chemical-resistant footwear. Immediate access to emergency eyewash stations and safety showers is required in all handling areas. Follow comprehensive OSHA guidelines for corrosive chemical management and maintain detailed chemical exposure monitoring protocols.
