2.3 Reactivity Alerts

Radioactive Material

Air & Water Reactions: Soluble in water.

Fire Hazard: No information available.

Health Hazard: Inhalation of dust may irritate nose and throat. Contact with eyes causes irritation. (USCG, 1999)

Reactivity Profile: Inorganic oxidizing agents can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers). The products may themselves be capable of further reactions (such as combustion in the air). The chemical reduction of materials in this group can be rapid or even explosive, but often requires initiation (heat, spark, catalyst, addition of a solvent). Inorganic oxidizing agents can react violently with active metals, cyanides, esters, and thiocyanates.

Explosives often consist of an inorganic oxidizing agent mixed in intimate contact with a reducing agent. Gunpowder is such a mixture. Other examples are a mixture of sugar (an organic compound) plus sodium chlorate and magnesium (an inorganic reducing agent) plus barium peroxide. Compounds that inherently contain a group that is a reducing agent, and an oxidizing agent are classed in both Group 44 (Inorganic Oxidizing Agents) and in Group 45 (Inorganic Reducing Agents; for example, ammonium nitrate).

The strongly oxidizing elements oxygen and fluorine are classified here. Inorganic oxidizing agents that are also acids (such as nitric and perchloric acids) are not included in this group. They are in Group 2 (Acids, Inorganic Oxidizing). (REACTIVITY, 2003) Belongs to reactive group(s).

3. Response Recommendations

General advice

Consult a physician. Show this safety data sheet to the doctor in attendance. Move out of dangerous area.

If inhaled

If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.

In case of skin contact

Flush with water. (USCG, 1999)

Protective Clothing

Approved dust respirator; goggles or face shield; protective clothing (USCG, 1999)

First Aid

Get medical attention after all exposures to this compound.


Give large amounts of water; induce vomiting.


Flush with water for at least 15 min.


4.1 Extinguishing media

4.4 Further information

No data available


5.1 Precautions for safe handling

Avoid contact with skin and eyes. Avoid formation of dust and aerosols.

Provide appropriate exhaust ventilation at places where dust is formed.

For precautions see section 2.2.

Keep container tightly closed in a dry and well-ventilated place.

5.3 Specific end use(s)

Apart from the uses mentioned in section 1.2 no other specific uses are stipulated.

6. Exposure controls

Appropriate engineering controls

Avoid contact with skin, eyes, and clothing. Wash hands before breaks and immediately after handling the product.

Personal protective equipment

Eye/face protection

Face shield and safety glasses Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).

Skin protection

Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove’s outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.

If used in solution, or mixed with other substances, and under conditions which differ from EN 374, contact the supplier of the CE approved gloves. This recommendation is advisory only and must be evaluated by an industrial hygienist and safety officer familiar with the specific situation of anticipated use by our customers. It should not be construed as offering an approval for any specific use scenario.

Body Protection

Complete suit protecting against chemicals, the type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.

Respiratory protection

Where risk assessment shows air-purifying respirators are appropriate use a full-face particle respirator type N100 (US) or type P3 (EN 143) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).

Control of environmental exposure

Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.
