First-aid measures
Fire-fighting measures
General Requirements
Avoid dispersion as a dust cloud.
Depending upon the scale of operation, use of appropriate exhaust ventilation is recommended to
provide routine control of fire and explosion hazards during handling of this material.
Ignition Controls
Bond and earth (ground) all plant and equipment to ensure that no isolated conductors are
present. Isolated conductors can accumulate sufficient electrostatic charge to produce discharges
of many hundreds of milli-Joules.
Consider earthing (grounding) personnel dealing with 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.
Minimise the use of plastics when handling this material. Handle and store this material only in
conductive or anti-static plastic liners (bags) since normal plastics are known to be capable of
producing electrostatic discharges of up to 4 mJ, ensuring that any containers into which they are
placed are themselves of a conductive material and earthed (grounded).
The maximum surface temperature of enclosures potentially exposed to this material should be
the lower of the values obtained by taking 2/3 of the minimum ignition temperature for a dust
cloud or 75 K less than the minimum ignition temperature of the dust layer, with a maximum
temperature of 325 °C.
Protective Systems
Assess operations based upon available dust explosion information to determine the suitability of
preventive or protective 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 low conductivity. Generation of electrostatic
charge is considered likely to occur even when handled in an earthed (grounded) environment.
At ambient humidity, this material has a very long charge relaxation time. Accumulation of
electrostatic charge is considered very likely to 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 discharge.
At low humidity, this material has an 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 discharge.
Accidental release measures
Exposure Controls
The hygiene guide for this material is <=10 mcg/m3. An Exposure Control Approach (ECA) is
established for operations involving this material based upon the OEL/Occupational Hazard
Category and the outcome of a site- or operation-specific risk assessment. Refer to the Exposure
Control Matrix for more information about how ECA's are assigned and how to interpret them.
Containment
Open handling may result in overexposure. It is strongly advised that dedicated areas and
containment, such as glove boxes, isolators, and enclosed material transfer systems be used to
prevent personnel exposure and spread of contamination.
Ventilation
Local exhaust ventilation (LEV) is not appropriate at this level, since total containment should
usually be used.
Administrative
Strict control of access to the working area is essential. Only trained personnel should enter the
area during operations. Adopt procedures to prevent contamination of working materials and
adjacent areas.

Exposure controls / personal protection
Eye Protection
When isolation is not possible, chemical splash goggles or equivalent eye protection must be
used with other applicable protective equipment.
Gloves
The selection of gloves for a specific activity must be based on the material's properties and on
possible permeation and degradation that may occur under the circumstances of use. Glove
selection must take into account any solvents and other hazards present. Potential allergic
reactions can occur with certain glove materials (e.g. Latex) and therefore these should be
avoided. Care must be exercised if insufficient data are available and further guidance should be
sought from your local EHS department.
Respirators
When isolation is not possible, respiratory protective equipment (RPE) should be combined with
applicable protective equipment.
Other Equipment or
Procedures
Follow all local regulations if personal protective equipment (PPE) is used in the workplace. When
isolation is not possible in production areas, appropriate personal protective equipment must be
used. Consider additional control procedures for maintenance, cleaning and emergencies.
