First-aid measures

Emergency measure - Inhalation: Using appropriate personnel protective equipment, move
exposed subject to fresh air. If breathing is difficult or
ceases, ensure and maintain ventilation. Give oxygen as
appropriate. The exposed subject should be kept warm and at
rest. Obtain medical attention in cases of known or
possible over exposure, or with symptoms including chest
pain, difficulty breathing, loss of consciousness or other
adverse effects, which may be delayed.
Emergency measure - Eyes: Wash immediately with clean and gently flowing water.
Continue for at least 15 minutes. Obtain medical attention.
Emergency measure - Skin: Using appropriate personal protective equipment, remove
contaminated clothing and flush exposured area with large
amounts of water. Obtain medical attention if skin reaction
occurs, which may be immediate or delayed.
Emergency measure - Ingestion: Obtain medical attention immediately.

Fire-fighting measures

Recommended extinguishing agent: Water, dry powder or foam extinguishers are recommended.
Carbon dioxide extinguishers maybe ineffective.

Product arising from burning: Oxides of carbon, boron compounds.

Product determined by test: N

Protective equipment: Since toxic, corrosive or flammable vapours might be evolved
from fires involving this material, self contained
breathing apparatus and full protective equipment are
recommended for firefighters.

Accidental release measures

Emergency measures in case of spillage: Fence or cordon the affected area and do not allow
individuals to touch or walk through the spilled material
unless wearing appropriate protective clothing. Avoid dust

Prevent entry into waterways, sewers, surface drainage
systems and poorly ventilated areas. If spill is outdoors,
cover with plastic sheet to minimise spreading or contact
with rain.

Collect and place it in a suitable, properly labelled
container for recovery and disposal.

No specific decontamination or detoxification procedures
have been identified for this material. Consider use of
water, detergent solutions, or other soluble solvents, for
clean-up and decontamination operations. Avoid
decontamination with oxidizing agents such as household
bleach which will release hazardous hydrochloric acid

Handling and storage

Handling: Any mechanical operations used for particle size reduction
should be performed in a manner that do not produce
localised heating. Bond and earth (ground) all plant and
equipment to ensure that no isolated conductors are present.
Consider earthing (grounding) personnel dealing wih dusty
operations. An isolated (insulated) human body can readily
produce electrostatic discharges in excess of 50 mJ, but
have been recorded up to 100 mJ.

The maximum surface temperature of enclosures potentially
exposed to this material should be based on the lower of the
values obtained by taking 2/3 minimum ignition temperature
of the dust cloud or 75k less than the minimum ignition
temperature of the dust layer.

Depending upon the scale of operation, a fume cupboard or
other type of exhaust ventilation is recommended to
routinely control exposure to this material.

Assess operations based upon available dust explosion
information to determine the suitability of preventive
systems as precautionary measures against possible dust
explosions. If prevention is not possible, consider
protection by use of containment, venting or suppression of
dust handling equipment. Where explosion venting is
considered the most appropriate method of protection, vent
areas should preferably be calculated based on the Kst
rather than the St value.

If nitrogen purging is considered as the protective system,
it must operate with an oxygen level below the limiting
oxygen concentration. The system should include an oxygen
monitoring and shut-down facility in the event of excessive
oxygen being detected.

At both ambient and low humidity, this material is of
appreciable conductivity. Generation and accumulation of
electrostatic charge is considered unlikely to occur when
handled in an earthed (grounded) environment. Under these
conditions, it is considered that this material might
present a low risk of producing an electrostatic discharge.
At ambient humidity, this material has a fast charge
relaxation time. Accumulation of electrostatic charge is
considered unlikely to occur when handled in an earthed
(grounded) environment. At the end of the charge
accumulation process charge is expected to be lost readily
to earth (ground).

At low humidity, material has extremely long charge
relaxation time. Accumulation of electrostatic charge will
occur even when handled in an earthed (grounded)
environment. Under these conditions, it is considered that
this material might present a very high risk of producing an
electrostatic charge.

Storage: Keep in tightly closed containers or packages away from
moisture and away from sources of ignition. Avoid prolonged
storage at elevated temperatures (greater than room
temperature, approximately 20 degrees C).

Packaging of the substance and or preparation: The substance is packed in 5 kg lots in a conductive
polyethylene bag with a nylon tie. Five of these bags are
packed inside a polyethylene liner in a 60 litre HDPE
Bowater drum.

Stability and reactivity

Danger other than fire: Thermal Stability:

Thermal hazard screening indicated that the rate of self-
heating and energy of decomposition may result in rapid and
vigorous decomposition. Gas or vapour may be evolved and
process equipment/container may rupture.

Materials to Avoid:

Strong acids. Strong oxidizing agents. Strong bases.

Conditions to Avoid:

Avoid direct sunlight, conditions that might generate heat
and dispersion as a dust cloud.

Dust explosion: This material is classified as a combustible solid and will
support propagating combustion.

Ignition of dust cloud produces a weak explosion.

Dust clouds are sensitive to electrostatic ignition.
