Section 5 - FIRE FIGHTING MEASURES
路 Cool fire exposed containers with water spray from a protected location.
路 If safe to do so, remove containers from path of fire.
路 Equipment should be thoroughly decontaminated after use.
FIRE/EXPLOSION HAZARD
路 Solid which exhibits difficult combustion or is difficult to ignite.
路 Avoid generating dust, particularly clouds of dust in a confined or unventilated space
as dusts may form an explosive mixture with air, and any source of ignition, i.e.
flame or spark, will cause fire or explosion. Dust clouds generated by the fine
grinding of the solid are a particular hazard; accumulations of fine dust may burn
rapidly and fiercely if ignited.
路 Dry dust can also be charged electrostatically by turbulence, pneumatic transport,
pouring, in exhaust ducts and during transport.
路 Build-up of electrostatic charge may be prevented by bonding and grounding.
路 Powder handling equipment such as dust collectors, dryers and mills may require
additional protection measures such as explosion venting.
路 All movable parts coming in contact with this material should have a speed of less than
1-metre/sec.
Combustion products include: carbon dioxide (CO2), ammonia and nitrogen oxides (NOx).
FIRE INCOMPATIBILITY
Avoid contamination with oxidising agents i.e. nitrates, oxidising acids, chlorine
bleaches, pool chlorine etc. as ignition may result.
HAZCHEM: None
Section 6 - ACCIDENTAL RELEASE MEASURES
EMERGENCY PROCEDURES
MINOR SPILLS
路 Clean up all spills immediately.
路 Avoid contact with skin and eyes.
路 Wear protective clothing, gloves, safety glasses and dust respirator.
路 Use dry clean up procedures and avoid generating dust.
路 Sweep up or
路 Vacuum up (consider explosion-proof machines designed to be grounded during storage and
use).

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
MATERIAL DATA
These "dusts" have little adverse effect on the lungs and do not produce toxic effects or
organic disease. Although there is no dust which does not evoke some cellular response at
sufficiently high concentrations, the cellular response caused by P.N.O.C.s has the
following characteristics:
路 the architecture of the air spaces remain intact,
路 scar tissue (collagen) is not synthesised to any degree,
路 tissue reaction is potentially reversible.
Extensive concentrations of P.N.O.C.s may:
路 seriously reduce visibility,
路 cause unpleasant deposits in the eyes, ears and nasal passages,
路 contribute to skin or mucous membrane injury by chemical or mechanical action, per se,
or by the rigorous skin cleansing procedures necessary for their removal. [ACGIH]
This limit does not apply:
路 to brief exposures to higher concentrations
路 nor does it apply to those substances that may cause physiological impairment at lower
concentrations but for which a TLV has as yet to be determined.
This exposure standard applies to particles which
路 are insoluble or poorly soluble* in water or, preferably, in aqueous lung fluid (if
data is available) and
路 have a low toxicity (i.e.. are not cytotoxic, genotoxic, or otherwise chemically
reactive with lung tissue, and do not emit ionizing radiation, cause immune sensitization
, or cause toxic effects other than by inflammation or by a mechanism of lung overload).
OEL STEL (Russia): 2 mg/m3
PERSONAL PROTECTION
EYE
路 Safety glasses with side shields
路 Chemical goggles.
路 Contact lenses may pose a special hazard; soft contact lenses may absorb and
concentrate irritants. A written policy document, describing the wearing of lens or
restrictions on use, should be created for each workplace or task. This should include a
review of lens absorption and adsorption for the class of chemicals in use and an account
of injury experience. Medical and first-aid personnel should be trained in their removal
and suitable equipment should be readily available. In the event of chemical exposure,
begin eye irrigation immediately and remove contact lens as soon as practicable. Lens
should be removed at the first signs of eye redness or irritation - lens should be
removed in a clean environment only after workers have washed hands thoroughly. [CDC
NIOSH Current Intelligence Bulletin 59].
HANDS/FEET
Wear general protective gloves: i.e. Disposable polythene gloves or Cotton gloves or
Light weight rubber gloves, with Barrier cream preferably Safety footwear.
OTHER
路 Overalls.
路 Barrier cream
路 Eyewash unit.

CHEMWATCH data (if available), or your
Occupational Health and Safety Advisor.
ENGINEERING CONTROLS
Use in a well-ventilated area.
路 Local exhaust ventilation is required where solids are handled as powders or crystals;
even when particulates are relatively large, a certain proportion will be powdered by
mutual friction.
路 Exhaust ventilation should be designed to prevent accumulation and recirculation of
particulates in the workplace.
路 If in spite of local exhaust an adverse concentration of the substance in air could
occur, respiratory protection should be considered. Such protection might consist of:
(a): particle dust respirators, if necessary, combined with an absorption cartridge;
(b): filter respirators with absorption cartridge or canister of the right type;
(c): fresh-air hoods or masks
路 Build-up of electrostatic charge on the dust particle, may be prevented by bonding and
grounding.
路 Powder handling equipment such as dust collectors, dryers and mills may require
additional protection measures such as explosion venting.
Air contaminants generated in the workplace possess varying "escape" velocities which, in
turn, determine the "capture velocities" of fresh circulating air required to efficiently
remove the contaminant.
Type of Contaminant: Air Speed:
direct spray, spray painting in shallow booths, 1- 2.5 m/s (200- 500 f/min.)
drum filling, conveyer loading, crusher dusts,
gas discharge (active generation into zone of
rapid air motion)
grinding, abrasive blasting, tumbling, high 2.5- 10 m/s (500- 2000 f/min.)
speed wheel generated dusts (released at high
initial velocity into zone of very high rapid
air motion).
Within each range the appropriate value depends on:
Lower end of the range Upper end of the range
1: Room air currents minimal or favourable to 1: Disturbing room air currents
capture
2: Contaminants of low toxicity or of nuisance 2: Contaminants of high toxicity
value only
3: Intermittent, low production. 3: High production, heavy use
4: Large hood or large air mass in motion 4: Small hood- local control only

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
Simple theory shows that air velocity falls rapidly with distance away from the opening
of a simple extraction pipe. Velocity generally decreases with the square of distance
from the extraction point (in simple cases). Therefore the air speed at the extraction
point should be adjusted, accordingly, after reference to distance from the contaminating
source. The air velocity at the extraction fan, for example, should be a minimum of 4-10
m/s (800-2000 f/min) for extraction of crusher dusts generated 2 metres distant from the
extraction point. Other mechanical considerations, producing performance deficits within
the extraction apparatus, make it essential that theoretical air velocities are
multiplied by factors of 10 or more when extraction systems are installed or used.

SKIN
The material may be. slightly discomforting to the skin.
Prolonged exposure may cause skin reactions.
INHALED
