Serious Skin Contact:
Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek medical
attention.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get
medical attention.
Serious Inhalation:
Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or
waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth
resuscitation. Seek medical attention.

Oxidizing material.
Stop leak if without risk. Avoid contact with a combustible material (wood, paper, oil, clothing...). Keep substance
damp using water spray. Do not touch spilled material. Prevent entry into sewers, basements or confined areas;
dike if needed. Eliminate all ignition sources. Call for assistance on disposal.
Section 7: Handling and Storage
Precautions:
Keep away from heat. Keep away from sources of ignition. Keep away from combustible material.. Empty
containers pose a fire risk, evaporate the residue under a fume hood. Ground all equipment containing material.
Do not ingest. Do not breathe dust. Wear suitable protective clothing. In case of insufficient ventilation, wear
suitable respiratory equipment. If ingested, seek medical advice immediately and show the container or the label.
Avoid contact with skin and eyes. Keep away from incompatibles such as reducing agents, organic materials.
Storage:
Keep container tightly closed. Keep container in a cool, well-ventilated area. Separate from acids, alkalies,
reducing agents and combustibles. See NFPA 43A, Code for the Storage of Liquid and Solid Oxidizers.
Section 8: Exposure Controls/Personal Protection
Engineering Controls:
Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below
recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to
airborne contaminants below the exposure limit.
Personal Protection:
Splash goggles. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent.
