Do not breathe dust.

Wear personal protection equipment.

Immediately remove any contaminated clothing, shoes or stockings.

Wash contaminated clothing before reuse.

Provide adequate ventilation.

Keep away from unprotected persons.

ENVIRONMENTAL PRECAUTIONS

Do not allow to enter into surface water or drains. If necessary, inform the competent authorities.

METHODS AND MATERIAL FOR CONTAINMENT AND CLEANING UP:

Avoid dust formation. Take up mechanically (by sweeping/ by vacuum cleaning with an approved industrial vacuum cleaner), placing in appropriate containers for disposal.

Do not sweep, if static charge may occur. In that case, keep product moist with as few water as possible. Dispose of waste according to applicable legislation. Clean area thoroughly afterwards

Exposure controls / personal protection

CONTROL PARAMETERS

- Exposure limits (EH40)

CAS No 26628-22-8

Substance Sodium azide (as NaN3)

Category

TWA (8h): 0.1 mg/m³ (Origin WEL)

STEL (15 min): 0.3 mg/m³ (Origin WEL)

EXPOSURE CONTROL

- Appropriate engineering controls

Transfer and handle product in closed systems, if possible. Provide adequate ventilation. If handled uncovered, arrangements with local exhaust ventilation should be used if possible. If technical exhaust or ventilation measures are not possible or insufficient, respiratory protection must be worn.

- Protective and hygiene measures

Avoid contact with the substance. Immediately remove any contaminated clothing, shoes or stockings. Wash contaminated clothing before reuse. Provide eye and emergency safety showers. Wash hands before breaks and after work. When using do not eat, drink or smoke.

- Eye/face protection

Wear eye/face protection.

- Hand protection

Wear suitable gloves. Replace when worn. The quality of the protective gloves resistant to chemicals must be chosen as a function of the specific working place concentration and quantity of hazardous substances.

For special purposes, it is recommended to check the resistance to chemicals of the protective gloves mentioned above together with the supplier of these gloves. See information supplied by the manufacturer.

Suitable material: Nitrile rubber

Use protective skin cream before handling the product.

- Skin protection

Wear suitable protective clothing. Choose body protection according to the amount and concentration of the dangerous substance at the work.

- Respiratory protection

If occupational exposure limits are exceeded, respiratory protection is necessary.

Use suitable breathing apparatus (full mask or mouthpiece) with ABEK-P2/P3 filter.

- Environmental exposure controls:

Do not allow to enter into surface water or drains.

Stability and reactivity

1. Reactivity

Refer to "Possibility of hazardous reactions"

2. Chemical stability

The substance is chemically stable under recommended conditions of storage, use and temperature.

3. Possibility of hazardous reactions

Contact with acids liberates very toxic gas. Contact with acids liberates explosive gases.

A danger of dust explosion may generally be assumed for dusty organic products.

Heating causes rise in pressure with risk of bursting.

4. Conditions to avoid

Intense heating. Avoid dust formation. Protect from moisture.

5. Incompatible materials

Heavy metals, carbon disulfide, hydrogen halide, water, nitrites

6. Hazardous decomposition products

In case of fire may be liberated: Nitrogen oxides (NOx), azides.

Disposal considerations

WASTE TREATMENT METHODS

- Advice on disposal

Do not allow to enter into surface water or drains.

Dispose according to legislation.

The destruction of sodium azide or sodium azide solutions is done by decomposing a nitric or sulfuric acid solution of sodium nitrite.

- Contaminated packaging

Completely emptied packages can be recycled.

Dispose according to legislation.
