First-aid measures

Never attempt to induce vomiting. Do not attempt to give any solid or liquid by mouth if the exposed subject is unconscious or semi-conscious. Wash out the mouth with water. If the exposed subject is fully conscious, give plenty of water to drink. Obtain medical attention.

Using appropriate personal 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.

Skin Contact
Using appropriate personal protective equipment, remove contaminated clothing and flush exposed area with large amounts of water. Obtain medical attention if skin reaction occurs, which may be immediate or delayed.

Eye Contact
Wash immediately with clean and gently flowing water. Continue for at least 15 minutes. Obtain medical attention.

Fire-fighting measures

This material is non-combustible.
Dust clouds are potentially of very low sensitivity to ignition from incendive electrostatic discharges.
Dust clouds are of very low sensitivity to ignition from hot surfaces. No ignition or exotherm of a powder layer observed up to 400 °C. Ignition of a dust cloud produces a weak dust explosion.
Moderate pressure between 6 and 8 bar is produced during a dust explosion.

Suitable extinguishing media:
No special requirements needed. Water is recommended for fires involving packaging.

Special Protective equipment and precautions for Firefighters
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. Move containers from the fire area if possible without increased personal risk.
If possible, contain and collect firefighting water for later disposal.

Specific hazards arising form the material
Toxic, corrosive or flammable thermal decomposition products, which might include sulphur compounds, are expected when the material is exposed to fire.

Accidental release measures

Personal precautions
Avoid dust generation. Wear protective clothing and equipment consistent with the degree of hazard. Instruct all personnel not involved in clean-up operations to keep at a designated safe distance.

Environmental Precautions:
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.

Decontamination procedures
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.

Handling and storage

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.
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. 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.
At both ambient and low humidity, this material has an extremely fast charge relaxation time. Accumulation of electrostatic charge is considered
unlikely to occur when handled in an earthed (grounded) environment.

Conditions for safe 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).

Exposure controls / personal protection

Open handling should be limited to small quantities. Consider use of enclosures.

Local exhaust ventilation (LEV) is recommended.

Only authorised personnel may enter the working area.

Personal protective equipment

Eye Protection
Wear approved safety glasses with side shields or cover goggles if eye contact is possible.

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.

If respiratory protective equipment (RPE) is used, the type of RPE will depend upon air concentrations present, required protection factor as well as
hazards, physical properties and warning properties of substances present. Follow local regulations for respirator use in the workplace.

Other equipment or procedures
Wear appropriate clothing to avoid skin contact. An eye wash station should be available.

Stability and reactivity

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

Disposal considerations

Collect for recycling or recovery if possible. The recommended method of disposal is incineration.
Wherever possible, disposal should be in an on-site licenced chemical incinerator, if allowed by the incinerator licence or permit. If no on-site
incinerator is available, dispose of material in a licenced commercial chemical incinerator.

Regulatory Requirements
Observe all local and national regulations when disposing of this material.
