Section 4 - FIRST AID MEASURES
SWALLOWED
鈥? If swallowed do NOT induce vomiting.
鈥? If vomiting occurs, lean patient forward or place on left side (head-down
position, if possible) to maintain open airway and prevent aspiration.
鈥? Observe the patient carefully.
鈥? Never give liquid to a person showing signs of being sleepy or with reduced
awareness; i.e. becoming unconscious.
鈥? Give water to rinse out mouth, then provide liquid slowly and as much as
casualty can comfortably drink.
鈥? Seek medical advice.
EYE
If this product comes in contact with the eyes:
鈥? Wash out immediately with fresh running water.
鈥? Ensure complete irrigation of the eye by keeping eyelids apart and away from
eye and moving the eyelids by occasionally lifting the upper and lower lids.
鈥? If pain persists or recurs seek medical attention.
鈥? Removal of contact lenses after an eye injury should only be undertaken by
skilled personnel.
SKIN
If skin or hair contact occurs:
鈥? Flush skin and hair with running water (and soap if available).
鈥? Seek medical attention in event of irritation.
INHALED
鈥? If fumes or combustion products are inhaled remove from contaminated area.
鈥? Other measures are usually unnecessary.
NOTES TO PHYSICIAN
Treat symptomatically.

Section 5 - FIRE FIGHTING MEASURES
鈥? Carbon dioxide.
FIRE FIGHTING
鈥? Alert Fire Brigade and tell them location and nature of hazard.
鈥? Wear breathing apparatus plus protective gloves for fire only.
鈥? Prevent, by any means available, spillage from entering drains or water
courses.
鈥? Use fire fighting procedures suitable for surrounding area.
鈥? DO NOT approach containers suspected to be hot.
鈥? Cool fire exposed containers with water spray from a protected location.
鈥? If safe to do so, remove containers from path of fire.
鈥? Equipment should be thoroughly decontaminated after use.
FIRE/EXPLOSION HAZARD
鈥? Solid which exhibits difficult combustion or is difficult to ignite.
鈥? 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
鈥? Dry dust can also be charged electrostatically by turbulence, pneumatic
transport, pouring, in exhaust ducts and during transport.
鈥? Build-up of electrostatic charge may be prevented by bonding and grounding.
鈥? Powder handling equipment such as dust collectors, dryers and mills may
require additional protection measures such as explosion venting.
鈥? All movable parts coming in contact with this material should have a speed of
less than 1-meter/sec.
Combustion products include carbon monoxide (CO).
FIRE INCOMPATIBILITY
Avoid contamination with oxidising agents i.e. nitrates, oxidising acids,
chlorine bleaches, pool chlorine etc. as ignition may result.

鈥? Sweep up or
鈥? Vacuum up (consider explosion-proof machines designed to be grounded during
storage and use).
鈥? Place spilled material in clean, dry, sealable, labelled container.

guar gum, propoxylated: No data available for CAS:39421-75-5
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:
鈥? the architecture of the air spaces remain intact,
鈥? scar tissue (collagen) is not synthesised to any degree,
鈥? tissue reaction is potentially reversible.
Extensive concentrations of P.N.O.C.s may:
鈥? seriously reduce visibility,
鈥? cause unpleasant deposits in the eyes, ears and nasal passages,
鈥? 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:
鈥? to brief exposures to higher concentrations
鈥? 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
鈥? are insoluble or poorly soluble* in water or, preferably, in aqueous lung
fluid (if data is available) and
鈥? 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).
PERSONAL PROTECTION
EYE
鈥? Safety glasses with side shields
鈥? Chemical goggles.
鈥? 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

ENGINEERING CONTROLS
鈥? 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.
鈥? Exhaust ventilation should be designed to prevent accumulation and
recirculation of particulates in the workplace.
鈥? 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
鈥? Build-up of electrostatic charge on the dust particle, may be prevented by
bonding and grounding.
鈥? 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 1-2.5 m/s (200-500 f/min.)
shallow "booths " drum "filling "
conveyer "loading " crusher "dusts "
gas discharge (active generation into
zone of rapid air motion)
grinding " abrasive "blasting " 2.5-10 m/s (500-2000 f/min.)

Within each range the appropriate value depends on:

3: Intermittent, low production. 3: High production, heavy use

motion
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.

EYE
The solid/dust is discomforting to the eyes.
The material may produce moderate eye irritation leading to inflammation.
Repeated or prolonged exposure to irritants may produce conjunctivitis.
SKIN
The material may be discomforting to the skin.
The material may cause skin irritation after prolonged or repeated exposure and
