Section 5 - FIRE FIGHTING MEASURES
路 Prevent, by any means available, spillage from entering drains or water courses.
DO NOT approach containers suspected to be hot.
Cool fire exposed containers with water spray from a protected location.
If safe to do so, remove containers from path of fire.
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.
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 impervious gloves and safety glasses.
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).
路 Place spilled material in clean, dry, sealable, labelled container.
MAJOR SPILLS
路 Clear area of personnel and move upwind.
路 Alert Fire Brigade and tell them location and nature of hazard.
路 Control personal contact by using protective equipment and dust respirator.
路 Prevent spillage from entering drains, sewers or water courses.
路 Avoid generating dust.
路 Sweep, shovel up. Recover product wherever possible.
路 Put residues in labelled plastic bags or other containers for disposal.
路 If contamination of drains or waterways occurs, advise emergency services.
Personal Protective Equipment advice is contained in Section 8 of the MSDS.
Section 7 - HANDLING AND STORAGE
PROCEDURE FOR HANDLING
路 Limit all unnecessary personal contact.

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
EYE
路 Safety glasses with side shields.
路 Chemical goggles.
路 Full face shield may be required for supplementary but never for primary protection of
eyes
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].

ENGINEERING CONTROLS
General exhaust is adequate under normal operating conditions. If risk of overexposure
exists, wear SAA approved respirator. Correct fit is essential to obtain adequate
protection. Provide adequate ventilation in warehouse or closed storage areas. Air
contaminants generated in the workplace possess varying "escape" velocities which, in
turn, determine the "capture velocities" of fresh circulating air required to effectively
remove the contaminant.
Type of Contaminant: Air Speed:
solvent, vapours, degreasing etc., evaporating 0.25- 0.5 m/s (50- 100 f/min)
from tank (in still air)
aerosols, fumes from pouring operations, 0.5- 1 m/s (100- 200 f/min.)
intermittent container filling, low speed
conveyer transfers, welding, spray drift,
plating acid fumes, pickling (released at low
velocity into zone of active generation)

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
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
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 1-2
m/s (200-400 f/min.) for extraction of solvents generated in a tank 2 meters 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.

Section 11 - TOXICOLOGICAL INFORMATION
POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
SWALLOWED
The material is moderately discomforting to the gastro-intestinal tract and may be
harmful if swallowed in large quantity.
EYE
The dust may produce eye discomfort causing smarting, pain and redness.
SKIN
The material may be mildly discomforting to the skin.
Prolonged exposure may cause skin reactions.
INHALED
The dust may be discomforting to the upper respiratory tract.
Persons with impaired respiratory function, airway diseases and conditions such as
emphysema or chronic bronchitis, may incur further disability if excessive concentrations
of particulate are inhaled.
CHRONIC HEALTH EFFECTS
Principal routes of exposure are by accidental skin and eye contact and inhalation of
generated dusts.
No human exposure data available. For this reason health effects described are based on
experience with chemically related materials.
As with any chemical product, contact with unprotected bare skin; inhalation of vapour,
mist or dust in work place atmosphere; or ingestion in any form, should be avoided by
observing good occupational work practice.
Sensitisation may give severe responses to very low levels of exposure, i.e.
hypersensitivity. Sensitised persons should not be allowed to work in situations where
exposure may occur.
TOXICITY AND IRRITATION
unless otherwise specified data extracted from RTECS - Register of Toxic Effects of Chemical Substances.
TOXICITY IRRITATION
Oral (rat) LD50: 4070 mg/kg Nil Reported
NOTE: Oral doses of 8-10g may cause nausea and vomiting, though tolerance
in human is 50 g/day. Use in food limited to 0.1%. [ICI]
