First-aid measures

General information:

If you feel unwell, seek medical advice (show the label where possible). Ensure that medical

personnel are aware of the material(s) involved, and take precautions to protect themselves.

4.1. Description of first aid measures


If exposure occurs at greater than the set OEL limits leave the exposure area immediately. Call a

physician if symptoms develop or persist.

Skin contact

Remove contaminated clothing immediately and wash skin with soap and water. In case of

eczema or other skin disorders: Seek medical attention and take along these instructions.

Eye contact

Rinse with water. Get medical attention if irritation develops and persists.


If swallowed, do NOT induce vomiting. Get medical attention if symptoms occur.

4.2. Most important symptoms

and effects, both acute and delayed:

Difficulty in breathing. May cause an allergic skin reaction. Dermatitis. Rash. Symptoms and

effects are generally associated with chronic exposure (i.e. lung fibrosis), and not acute.

4.3. Indication of any immediate medical attention and special treatment needed:

Provide general supportive measures and treat symptomatically. Keep victim under observation.

Symptoms may be delayed.

Fire-fighting measures

General fire hazards

Fine particles may form explosive mixtures with air.

5.1. Extinguishing media

Suitable extinguishing media:

Use fire-extinguishing media appropriate for surrounding materials.

Unsuitable extinguishing media:

Do not use water jet as an extinguisher, as this will spread the fire.

5.2. Special hazards arising from the substance or mixture

The product is not flammable. May evolve toxic nitrogen/ sulphur/nickel/cobalt oxides and

ammonia when heated to decomposition. Very finely divided nickel metal in the fully reduced state can smoulder in the presence of oxygen or air. High concentrations of dust may form explosive mixture with air. Spontaneous combustion may occur when moisture content falls between 5-10%.

5.3. Advice for firefighters

Special protective equipment for firefighters

Self-contained breathing apparatus and full protective clothing must be worn in case of fire.

Special fire fighting procedures

Evacuate area. Stay upwind. Move containers from fire area if you can do it without risk. Prevent

runoff from fire control or dilution from entering streams, sewers or drinking water supply. Use

water fog to cool intact containers and nearby storage areas.

Specific methods

Use standard firefighting procedures and consider the hazards of other involved materials.

Accidental release measures

6.1. Personal precautions, protective equipment and emergency procedures

For non-emergency personnel

Keep unnecessary personnel away. Keep people away from and upwind of spill/leak. Wear

appropriate protective equipment and clothing during clean-up. Avoid inhalation of dust. Do not

touch damaged containers or spilled material unless wearing appropriate protective clothing.

Ensure adequate ventilation. Local authorities should be advised if significant spillages cannot be


For emergency responders:

Keep unnecessary personnel away. Use personal protection recommended in Section 8 of the


6.2. Environmental precautions

Avoid release to the environment. Prevent further leakage or spillage if safe to do so. Avoid

discharge into drains, water courses or onto the ground. Inform appropriate managerial or

supervisory personnel of all environmental releases.

6.3. Methods and material for containment and cleaning up

Avoid the generation of dusts during clean-up. Stop the flow of material, if this is without risk.

Sweep up or vacuum up spillage and collect in suitable container for disposal. Containers must be labeled.

6.4. Reference to other sections:

For personal protection, see section 8. For waste disposal, see section 13 of the SDS.

Handling and storage

7.1. Precautions for safe handling

Obtain special instructions before use. Do not handle until all safety precautions have been read

and understood. Provide adequate ventilation. Minimise dust generation and accumulation. Avoid

breathing dust. Avoid contact with eyes, skin, and clothing. Avoid prolonged exposure. Should be

handled in closed systems, if possible. Persons susceptible for allergic reactions should not

handle this product. Pregnant or breastfeeding women must not handle this product. Wear

appropriate personal protective equipment. Observe good industrial hygiene practices. Wash

hands before eating. Do not eat, drink or smoke when using the product.

7.2. Conditions for safe storage, including any incompatibilities

Store locked up. Store in original tightly closed container. Store in a cool, dry, well-ventilated place.

Store away from incompatible materials (see Section 10 of the SDS). If stored in bulk, minimize

dust generation by dampening with water or covering with a tarp or similar. If stored in packages,

ensure packages are adequately labelled, and check regularly for leaks or spills. Do not store in

unlabelled containers.

7.3. Specific end use(s)

Isolated transported intermediate under strictly controlled conditions.

Exposure controls / personal protection

8.1. Control parameters

Occupational exposure limits

Finland. Workplace Exposure Limits

Cobalt sulphide (CAS 1317-42-6) TWA 0,02 mg/m3

Nickel sulphide (CAS 16812-54-7) TWA 0,05 mg/m3 Inhalable dust. and 0,01 mg/m3 Respirable.

Biological limit values:

No biological exposure limits noted for the ingredient(s).

Recommended monitoring procedures:

Follow standard monitoring procedures.

8.2. Exposure controls

Appropriate engineering controls

Good general ventilation (typically 10 air changes per hour) should be used. Ventilation rates

should be matched to conditions. If applicable, use process enclosures, local exhaust ventilation,

or other engineering controls to maintain airborne levels below recommended exposure limits. If

exposure limits have not been established, maintain airborne levels to an acceptable level.

Individual protection measures, such as personal protective equipment:

General information

Use personal protective equipment as required. Personal protection equipment should be chosen

according to the CEN standards and in discussion with the supplier of the personal protective


Eye/face protection

If contact is likely, safety glasses with side shields are recommended.

Skin - hand protection

Wear appropriate chemical resistant gloves. Nitrile/PVC/rubber gloves are recommended. Suitable gloves can be recommended by the glove supplier.

Other Respiratory protection:

Wear appropriate chemical resistant clothing.

In case of inadequate ventilation or risk of inhalation of dust, use suitable respiratory equipment

with particle filter.

Thermal hazards

Wear appropriate thermal protective clothing, when necessary.

Hygiene measures

Keep away from food and drink. Always observe good personal hygiene measures, such as

washing after handling the material and before eating, drinking, and/or smoking. Routinely wash

work clothing and protective equipment to remove contaminants. Contaminated work clothing

should not be allowed out of the workplace. Observe any medical surveillance requirements.

Environmental exposure controls:

Environmental manager must be informed of all major releases.

Stability and reactivity

10.1. Reactivity

The product is stable and non-reactive under normal conditions of use, storage and transport.

10.2. Chemical stability

smoulder in the presence of oxygen or air.

10.3. Possibility of hazardous reactions

No dangerous reaction known under conditions of normal use. Hazardous polymerisation will not


10.4. Conditions to avoid

Contact with incompatible materials. Dust generation. Avoid heat, sparks, open flames and other

ignition sources.

10.5. Incompatible materials

Nickel is attacked slowly by sulphuric or dilute hydrochloric acid; it is readily attacked by nitric acid.

Evolving highly flammable hydrogen gas. Under special conditions nickel can react with carbon

monoxide in reducing atmospheres to form Nickel Carbonyl, a toxic gas. Avoid contact with

oxidizing agents (e.g. nitrates, peroxides).

10.6. Hazardous decomposition products
