They can be as simple as a bag of citric acid or sodium sesquicarbonate, or as complex as a solidifier and neutralizer combined. Handling: Before handling, it is important that all engineering controls are operating and that protective equipment requirements and personal hygiene measures are being followed. Do not handle swollen drums. Incompatible with many common chemicals. It may be necessary to use stringent control measures such as process enclosure to prevent product release into the workplace. Contain spills or leaks by storing containers in trays made from compatible materials. The best way to measure this is to take the pH of the solution using pH paper, chemical indicators, or pH meters. Use a weak acid to neutralize bases. Recommendations are NOT valid for very thin natural rubber, neoprene rubber, nitrile rubber, and PVC gloves (0.3 mm or less). Odour: Odourless. Chemicals with a pH of 7 are considered neutral acids and typically have a pH less than 7. Contact with metals liberates flammable hydrogen gas. Specific Hazards Arising from the Chemical: Contact with water causes violent frothing and spattering. To neutralize them, use a weak base.

Quickly take off contaminated clothing, shoes and leather goods (e.g. It is either neutralized, or it is not. Storage: Store in an area that is: cool, dry, well-ventilated, separate from incompatible materials. Wear chemical protective gloves if necessary. Neutralizing an acidic or caustic material during spill cleanup makes the material safer to handle and dramatically reduces disposal costs. indirectly from any use or reliance upon the information. Eye contact. Many different products aid in the neutralization of acids and bases. Take proper precautions as recommended by the neutralizer’s manufacturer. Contact us to let us know. CCOHS is not liable for any loss, claim, or demand arising directly or Methods for Containment and Clean-up: Contain and soak up spill with absorbent that does not react with spilled product.
