Section 4 - FIRST AID MEASURES
SWALLOWED
For advice, contact a Poisons Information Centre or a doctor.
路 If swallowed do NOT induce vomiting.
路 If vomiting occurs, lean patient forward or place on left side (head-down position, if
possible) to maintain open airway and prevent aspiration.
路 Observe the patient carefully.
路 Never give liquid to a person showing signs of being sleepy or with reduced awareness;
i.e. becoming unconscious
路 Give water to rinse out mouth, then provide liquid slowly and as much as casualty can
comfortably drink.
路 Seek medical advice.
EYE
If this product comes in contact with the eyes:
路 Immediately hold eyelids apart and flush the eye continuously with running water.
路 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.
路 Continue flushing until advised to stop by the Poisons Information Centre or a doctor,
or for at least 15 minutes.
路 Transport to hospital or doctor without delay.
路 Removal of contact lenses after an eye injury should only be undertaken by skilled
personnel.
SKIN
If skin or hair contact occurs:
路 Flush skin and hair with running water (and soap if available).
路 Seek medical attention in event of irritation.
or In case of burns:
路 Immediately apply cold water to burn either by immersion or wrapping with saturated
clean cloth.
路 DO NOT remove or cut away clothing over burnt areas. DO NOT pull away clothing which
has adhered to the skin as this can cause further injury.
路 DO NOT break blister or remove solidified material.
路 Quickly cover wound with dressing or clean cloth to help prevent infection and to ease
pain.
路 For large burns, sheets, towels or pillow slips are ideal; leave holes for eyes, nose
and mouth.
路 DO NOT apply ointments, oils, butter, etc. to a burn under any circumstances.
路 Water may be given in small quantities if the person is conscious.
路 Alcohol is not to be given under any circumstances.
路 Reassure.
路 Treat for shock by keeping the person warm and in a lying position.

Section 4 - FIRST AID MEASURES
路 Seek medical aid and advise medical personnel in advance of the cause and extent of the
injury and the estimated time of arrival of the patient.
INHALED
路 If dust is inhaled, remove from contaminated area.
路 Encourage patient to blow nose to ensure clear passage of breathing.
路 If irritation or discomfort persists seek medical attention.
路 If fumes or combustion products are inhaled remove from contaminated area.
路 Lay patient down. Keep warm and rested.
路 Prostheses such as false teeth, which may block airway, should be removed, where
possible, prior to initiating first aid procedures.
路 Apply artificial respiration if not breathing, preferably with a demand valve
resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary.
路 Transport to hospital, or doctor.
NOTES TO PHYSICIAN
Treat symptomatically.
Section 5 - FIRE FIGHTING MEASURES
EXTINGUISHING MEDIA
路 Foam.
路 Dry chemical powder.
路 BCF (where regulations permit).
路 Carbon dioxide.
路 Water spray or fog - Large fires only.
FIRE FIGHTING
Alert Fire Brigade and tell them location and nature of hazard.
路 Wear breathing apparatus plus protective gloves.
路 Prevent, by any means available, spillage from entering drains or water courses.
NOTE: Burns with intense heat. Produces melting, flowing, burning liquid and dense acrid
black smoke.
Cool fire exposed containers with water spray from a protected location.
If safe to do so, remove containers from path of fire.
Equipment should be thoroughly decontaminated after use.
FIRE/EXPLOSION HAZARD
路 Combustible.
路 Slight fire hazard when exposed to heat or flame.
路 Heating may cause expansion or decomposition leading to violent rupture of containers.
路 On combustion, may emit toxic fumes of carbon monoxide (CO).
路 May emit acrid smoke.
路 Mists containing combustible materials may be explosive.
NOTE: Burns with intense heat. Produces melting, flowing, burning liquid and dense acrid
black smoke.
FIRE INCOMPATIBILITY
Avoid contamination with strong oxidising agents as ignition may result.
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.

EXPOSURE CONTROLS
The following materials had no OELs on our records
鈥? microcrystalline wax: CAS:63231- 60- 7
MATERIAL DATA
No exposure limits set by NOHSC or ACGIH.
PERSONAL PROTECTION
EYE
路 Safety glasses with side shields; or as required,
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.
or. When handling hot material, wear Protective gloves eg. Leather gloves or gloves with

CHEMWATCH data (if available), or your
Occupational Health and Safety Advisor.
ENGINEERING CONTROLS
None required when handling small quantities.
OTHERWISE:.
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:

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 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.
