Hydrogen Peroxide (H₂O₂)

Introduction

Hydrogen Peroxide (H₂O₂) is a strong oxidizing agent used across various industries. At concentrations of 35% and above, it poses risks of chemical burns, fire enhancement, and decomposition under heat or contamination. Safe handling procedures are essential to prevent incidents.

Hazard Summary

• Strong oxidizer; may intensify fire.
• Causes severe skin burns and eye damage.
• Decomposes violently if contaminated or heated.
• Releases oxygen; can cause container rupture.
• Contact with combustibles can cause fires.

Personal Protective Equipment (PPE)

Mandatory PPE for handling H₂O₂ 35%:

• Chemical splash goggles + Face shield
• Acid-resistant gloves (nitrile/neoprene)
• Full-sleeve chemical-resistant apron/suit (PVC/neoprene)
• Safety boots
• Respirator (if in enclosed space or spill situation)

Storage & Handling Guidelines

Storage

• Store in original vented HDPE containers.
• Keep in cool, well-ventilated area away from sunlight and heat.
• Segregate from flammable materials, organics, and metals.
• Do not store near acids or alkalis.
• Use secondary containment trays.

Handling

• Use only with trained personnel and proper PPE..
• Avoid contamination; use clean, non-metallic tools.
• Transfer using dedicated peristaltic or Teflon-lined pumps.
• Always add peroxide to water (never the reverse).
• Never return unused peroxide to original container.

Spill Management

During Transportation

• Stop vehicle and assess the leak.
• Evacuate area and notify emergency contacts.
• Avoid combustible absorbents (e.g., sawdust).
• Use inert absorbents like vermiculite or sand.
• Collect waste into clean, vented HDPE drums.

On Factory Floor

• Isolate area and evacuate personnel.
• Wear full PPE.
• Ventilate area to avoid oxygen accumulation.
• Absorb with inert material and transfer to vented HDPE.
• Do not use bleach, organic cleaners, or acids to clean spill.

First Aid Procedure

Skin Contact

• Rinse with water for at least 15–20 minutes.
• Remove contaminated clothing.
• Seek medical evaluation.

Eye Contact

• Rinse eyes immediately with water for 15–20 minutes.
• Seek immediate ophthalmologic attention.

Inhalation

• Move victim to fresh air.
• Administer oxygen if breathing is difficult.
• Seek immediate medical help.

Ingestion

• Do NOT induce vomiting.
• Rinse mouth, give water or milk if conscious.
• Immediate hospitalization required.

Emergency Equipment Checklist

• Eye wash stations and safety showers
• First aid kit with burn gel
• Clean inert absorbent (vermiculite/sand)
• Ventilated HDPE spill drums
• PPE kits near peroxide handling zone
• “NO ORGANICS / FLAMMABLES” signage
• Emergency oxygen supply and stretcher

Waste Disposal

• Do not mix with other waste chemicals.
• Collect in vented HDPE drums.
• Label as “Hydrogen Peroxide Waste – Hazardous”.
• Dispose via licensed hazardous waste handler as per rules.
