What is the PEL for sodium hydroxide
The Permissible Exposure Limit (PEL) for sodium hydroxide is 2 mg/m3. This is based on OSHA Table Z-1 Limits for Air Contaminants (29 CFR 1910.1000). [1]
When handling sodium hydroxide, it is crucial to use appropriate engineering controls such as local exhaust ventilation to maintain airborne levels within acceptable limits. Eye wash facilities and emergency showers should be available. [1]
Personal Protective Equipment (PPE) is essential. This includes:
- Eye protection: Wear safety glasses with side shields (or goggles) and a face shield.
- Hand protection: Wear appropriate chemical resistant gloves.
- Skin protection: Wear appropriate chemical resistant clothing.
[1] Sodium hydroxide can cause severe skin burns and eye damage. It is also harmful to aquatic life. Ensure you follow all safety precautions outlined in the Safety Data Sheet (SDS). [3]
Always add corrosives slowly to COLD water and use corrosion-resistant tools and equipment. Avoid generating vapors or mists and dusts. [2]
Important Safety Note:
Always verify safety information with your organization's specific guidelines and local regulations.
