Guidance on Safe Use
Administrative data
First-aid measures
Eye contact: Immediately flush eyes with plenty of water, occasionally lifting the upper and lower
eyelids. Continue to rinse for at least 10 minutes. Get medical attention.
Inhalation:
Remove victim to fresh air and keep at rest in a position comfortable for breathing.
If it is suspected that fumes are still present, the rescuer should wear an appropriate
mask or self-contained breathing apparatus. If not breathing, if breathing is irregular
or if respiratory arrest occurs, provide artificial respiration or oxygen by trained
personnel. It may be dangerous to the person providing aid to give mouth-to-mouth
resuscitation. Get medical attention. If unconscious, place in recovery position and
get medical attention immediately. Maintain an open airway. Loosen tight clothing
such as a collar, tie, belt or waistband.
Skin contact:
Wash with plenty of soap and water. Remove contaminated clothing and shoes.
Wash contaminated clothing thoroughly with water before removing it, or wear
gloves. Continue to rinse for at least 10 minutes. Get medical attention. In the
event of any complaints or symptoms, avoid further exposure. Wash clothing
before reuse. Clean shoes thoroughly before reuse.
Ingestion:
Wash out mouth with water. Remove dentures if any. Remove victim to fresh air
and keep at rest in a position comfortable for breathing. If material has been
swallowed and the exposed person is conscious, give small quantities of water to
drink. Stop if the exposed person feels sick as vomiting may be dangerous. Do not
induce vomiting unless directed to do so by medical personnel. If vomiting occurs,
the head should be kept low so that vomit does not enter the lungs. Get medical
attention. Never give anything by mouth to an unconscious person. If unconscious,
place in recovery position and get medical attention immediately. Maintain an open
airway. Loosen tight clothing such as a collar, tie, belt or waistband.
Protection of first aiders:
No action shall be taken involving any personal risk or without suitable training. If it
is suspected that fumes are still present, the rescuer should wear an appropriate
mask or self-contained breathing apparatus. It may be dangerous to the person
providing aid to give mouth-to-mouth resuscitation. Wash contaminated clothing
thoroughly with water before removing it, or wear gloves.
Fire-fighting measures
Suitable extinguishing media: Use an extinguishing agent suitable for the surrounding fire.
Unsuitable extinguishing media: None known
Hazards from substance or mixture:
In case of fire toxic nickel carbonyl can be formed. Combustible when exposed to
heat or flame. Heated material can cause thermal burns. This material is toxic to
aquatic life with long lasting effects. Fire water contaminated with this material must
be contained and prevented from being discharged to any waterway, sewer or drain.
Decomposition products may include the following materials:
sulfur oxides
metal oxide/oxides
Fire-fighters should wear appropriate protective equipment and self-contained
breathing apparatus (SCBA) with a full face-piece operated in positive pressure
mode. Clothing for fire-fighters (including helmets, protective boots and gloves)
conforming to European standard EN 469 will provide a basic level of protection for
chemical incidents.
Accidental release measures
No action shall be taken involving any personal risk or without suitable training.
Evacuate surrounding areas. Keep unnecessary and unprotected personnel from
entering. Do not touch or walk through spilt material. Provide adequate ventilation.
Wear appropriate respirator when ventilation is inadequate. Put on appropriate
personal protective equipment.
Environmental precautions:
Avoid dispersal of spilt material and runoff and contact with soil, waterways, drains
and sewers. Inform the relevant authorities if the product has caused environmental
pollution (sewers, waterways, soil or air). Water polluting material. May be harmful
to the environment if released in large quantities. Collect spillage.
Methods for containments and clearing up:
Small spill: Move containers from spill area. Avoid dust generation. Do not dry sweep.
Vacuum dust with equipment fitted with a HEPA filter and place in a closed, labeled
waste container. Place spilled material in a designated, labeled waste container.
Dispose of via a licensed waste disposal contractor.
Large spill:
Move containers from spill area. Approach the release from upwind. Prevent entry
into sewers, water courses, basements or confined areas. Avoid dust generation.
Do not dry sweep. Vacuum dust with equipment fitted with a HEPA filter and place
in a closed, labeled waste container. Dispose of via a licensed waste disposal
contractor.
Handling and storage
Protective measures:
Put on appropriate personal protective equipment. Persons with a
history of skin sensitization problems should not be employed in any process in
which this product is used. Avoid exposure - obtain special instructions before use.
Do not handle until all safety precautions have been read and understood. Do not
get in eyes or on skin or clothing. Do not ingest. Avoid release to the environment.
If during normal use the material presents a respiratory hazard, use only with
adequate ventilation or wear appropriate respirator. Keep in the original container or
an approved alternative made from a compatible material, kept tightly closed when
not in use. Empty containers retain product residue and can be hazardous. Do not
reuse container.
Conditions for safe storage:
Do not store above the following temperature: 40°C (104°F). Store in accordance
with local regulations. Store in a dry place. Keep cool. Protect from sunlight. Keep
only in the original container. Keep container tightly closed and sealed until ready
for use. Containers that have been opened must be carefully resealed and kept
upright to prevent leakage. Do not store in unlabelled containers. Use appropriate
containment to avoid environmental contamination. Store away from incompatible
materials

Exposure controls / personal protection
Engineering controls:
If user operations generate dust, fumes, gas, vapour or mist, use process
enclosures, local exhaust ventilation or other engineering controls to keep worker
exposure to airborne contaminants below any recommended or statutory limits.
Eye/face protection:
Safety eyewear complying with an approved standard (EN 166 or local equivalent)
is required during loading and unloading of reactors, cleaning and maintenance
operations, and sampling, where exposure to dust, powder or liquid splashes is
possible.
Hand protection:
Chemical/bio-chemical resistant, impervious gloves complying with an approved
chemical standard (EN 374 or local equivalent) should be worn at all times when
handling chemical products. For tasks involving physical or mechanical hazards,
gloves should also comply with an approved physical standard (EN 388 or local
equivalent).
Body protection:
Safety shoes complying with an approved standard (EN 20346 or equivalent) and a
hard hat complying with an approved standard (EN 297 or equivalent) is required
during loading and unloading of reactors, cleaning and maintenance operations and
sampling.
Other skin protection:
A protective suit complying with an approved standard (EN 13982-1 Type 5 or
equivalent) should be worn during loading and unloading or reactors, sampling and
cleaning and maintenance operations where dermal contact is possible.
Respiratory protection:
Use of Respiratory Protective Equipment (RPE) (Particle filter with high efficiency
for solid particles (EN 143 or 149, Type P3 or FFP3, Associated Protection Factor
(APF) = 20) or local equivalent as a minimum) is required during loading and
unloading of reactors, cleaning and maintenance operations, and sampling, where
exposure to dust or powder is possible. Air-fed Respiratory Protective Equipment
may be used if entry to the reactor is required.
Environmental exposure controls:
Emissions from ventilation or work process equipment should be checked to
ensure they comply with the requirements of environmental protection legislation.
In some cases, fume scrubbers, filters or engineering modifications to the process
equipment will be necessary to reduce emissions to acceptable levels.
