Nickel dichloride

Guidance on Safe Use

First-aid measures

INGESTION: in case of accidental ingestion estimated at less than 0.5 g approximately, drink plenty of water. For higher quantities, seek medical attention to have the stomach pumped.

INHALATION: remove to fresh air. In extreme situations, give oxygen and seek medical attention.

SKIN CONTACT: wash thoroughly with water for at least 15 to 20 minutes. In case of beginning of a skin reaction, seek medical attention.

In case of possible wounds, wash it abundantly for 15 to 20 minutes and make sure that any nickel chloride particle has been removed.

CONTACT WITH EYES: irrigate thoroughly with water for at least 20 minutes. Seek medical attention.

Fire-fighting measures

Non inflammable

In case of fire close by, may evolve gaseous hydrochloric acid if rapidly heated above 300°C. Extinguish the nearest fire by using the most suitable method.

Accidental release measures

Individual protection: wear acid resistant gloves. If any operation create dust, wear an nationally approved respirator.

Precautions for environmental protection: do not drain off in sewage, surface water, groundwater, or on soil.

Cleaning up methods: (for nickel chloride crystals)

-As much as possible, avoid creating dust.

-If the product does not seem to be contaminated, recover it by means of a shovel or a similar tool.

-If the product has been contaminated, recover it by means of a shovel or vacuum cleaner in order to recycle it to a certified station for waste treatment. In case of aspiration, the vacuum-cleaner must have an efficient filter, and staff must wear a nationally approved respirator.

-If the product has been dissolved in water, use lime or soda ash. Then recover the sludge by use of an inert absorbent.

Cleaning up methods: (for nickel chloride solution)

In case of discharge:

- Stop the leak. Raise the damaged packaging (if leak on top) to stop liquid discharge.

- Stop the spilt liquid from spreading.

- Do not drain off in sewage or in rivers.

- Use lime or soda ash in order to precipitate nickel into a solid state. Then, recover the sludge by use of an inert absorbent.

Handling and storage

HANDLING (solution)

Avoid any direct contact with the product.

Avoid the creation of spray.

Wear gloves, suitable protective clothing and goggles.

In case of exposure to spray, wear a nationally approved respirator.

HANDLING (crystals)

Avoid any direct contact with the product.

Avoid the creation of dust.

Wear gloves, suitable protective clothing and goggles.

In case of exposure to dust or aerosols, wear a nationally approved respirator.

STORAGE (solution)

Use corrosion resistant tanks ( made of plastics …) placed inside a sufficiently large watertight basin.

Check the need for local compliance with weight limit for storage.

Liquid nickel chloride is packaged in square plastic containers of 1m3 in high density polypropylene or sold in bulk by tanker lorry (around 17 m3).

STORAGE (crystals)

In dry conditions, in closed packaging. Check the need for local compliance with weight limit for storage. The product is delivered in a polypropylene bag.

Exposure controls / personal protection

Exposure limit values: In the UK, the exposure limit value (average over 8 hours) for nickel soluble compound is 0.1 mg Ni/Nm3.  This corresponds to a fixed limit value of 0.4 mg/Nm3, expressed in NiCl2, 6H2O.(CRYSTALS)   This corresponds to a fixed limit value of 0.7 mg/Nm3, expressed in nickel chloride in aqueous solution.(SOLUTION)

EXPOSURE CONTROLS

Occupational exposure control: Respiratory protection: If the process or the technology used creates dust or spray, the equipment include a ventilator so that the exposure is as low as reasonably possible, and must be below the nationally recommended limit (in the UK: 0.1 mg/Nm3 in Ni (soluble compound) - average over 8 hours). In case of exposure above this limit value, use respirators approved by the national authorities.

Occupational exposure control: Hand protection: wear acid-resistant gloves.

Occupational exposure control: Eye protection: wear goggles with lateral protection.

Occupational exposure control: Skin protection: Wear suitable acid-resistant clothing which should be laundered as required. A good personal hygiene is highly recommended.

Environmental exposure controls: Do not drain off in sewage, natural water or on soil.

Stability and reactivity

Conditions to avoid

- Stable product under normal conditions.

- If the preparation is heated at high temperature (>300°C), the water will evaporate causing a risk of emission of gaseous hydrochloric acid (which is a dangerous gas) and risk of transformation of nickel chloride into nickel monoxide, which is classified Carcinogenic Category 1 with risk phrases R49, R43.

Materials to avoid

-Do not boil after mixing (or dissolving) with sulphuric acid: may form gaseous hydrochloric acid, after evaporation of water, which is a dangerous gas.

Hazardous decomposition products

-Dehydrates above 103°C (crystals)

-By reaction with concentrated sulphuric acid at high temperature (>100°C) may form gaseous hydrochloric acid, which is a dangerous gas.

-Decomposition during heating at a temperature over 300°C: may form gaseous hydrochloric acid, which is a dangerous gas and may transform nickel chloride into nickel monoxide (NiO), which is classified Carcinogenic Category 1 with risk phrases R49, R43.

Disposal considerations

Comply with local regulations applicable to industrial plants and laws on waste disposal.

Waste waters must be treated either on site, or in certified outside plants.

In the same way, solid wastes (sludge, etc…) must be sent to a certified treatment plant.

The contaminated packaging (polypropylene bag) should not be used again and must be treated in compliance with the appropriate regulations.

Remark: the user’s attention is drawn to the possible existence of local or national regulations, related to disposal, which may be applicable.
