HEALTH HAZARDS
Health Hazard Corrosive. Use safe work practices to avoid eye - skin contact and dust generation-
Summary inhalation. Once water is added an inhalation hazard is not anticipated. Chronic
respiratory effects are not anticipated with over exposure at high levels due to the
immediate irritant and/or corrosive effects.
Eye Corrosive - severe irritant. Exposure may result in pain, redness, corneal burns and
ulceration with possible permanent damage with prolonged contact.
Inhalation Corrosive. Over exposure to powder - dust (when mixing) may result in severe
mucous membrane irritation of nose and throat, coughing and bronchitis at high
levels.
Skin Corrosive. Prolonged and repeated contact may result in skin rash, dermatitis and
ulceration.
Ingestion Corrosive, Ingestion may result in ulceration and burns to the mouth and throat,
nausea, vomiting, abdominal pain and diarrhoea.

PRECAUTIONS
Flammability Non flammable, No fire or explosion hazard exists.
Reactivity Incompatible (violently) with acids, maleic anhydride, nitroethane, nitromethane,
nitroparaffins, nitropropane and phosphorus.
Ventilation Do not inhale dust/ powder. Use with adequate natural ventilation. Where a dust
inhalation hazard exists mechanical extraction ventilation is recommended.

PERSONAL PROTECTIVE EQUIPMENT
PPE Wear dust-proof goggles and PVC or rubber gloves. When using large quantities or
where heavy contamination is likely, wear coveralls. Where an Inhalation risk exists,
wear a Class P1 (Particulate) Respirator. At high dust levels wear a Powered Air
Purifying Respirator (PAPR) with Class P3 (Particulate) filter or a Full-face Class P3
(Particulate) respirator.

FIRST AID
Eye Flush gently with running water, holding eyelids open for 20 minute period. Seek
immediate medical attention.
Inhalation If over exposure occurs leave exposure area immediately. If other than minor
symptoms are displayed seek immediate medical attention.
Skin Remove contaminated clothing and gently flush affected areas with water. Seek
medical attention if irritation develops. Launder clothing before reuse.
Ingestion If poisoning occurs, contact a Doctor or Poisons Information Centre on 03 474 7000
or 03 479 1200 9am - 5pm weekdays. Do not induce vomiting. Seek immediate
medical attention.
First Aid Eye wash facilities should be available.

SAFE HANDLING
Storage Store in cool, dry, well ventilated area, removed from acids, maleic anhydride,
nitroethane, nitromethane, nitroparaffin, nitropropane, phosphorus and foodstuffs.
Ensure packages are adequately labelled, protected from physical damage and
sealed when not in use.
Waste Neutralise with dilute acid (eg. 3 mol/L hydrochloric acid) or similar. For small
Disposal amounts absorb with sand or similar and dispose of to an approved landfill site.
Contact manufacturer for additional information.
Transport Not regulated for transport purposes.

EMERGENCY
Spillage If spilt (bulk), contact emergency services if appropriate. Wear dust-proof goggles,
PVC/rubber gloves, a Class P1 (Particulate) respirator (where an inhalation risk
exists) coveralls and rubber boots. Clear area of all unprotected personnel. Prevent
spill entering drains or waterways. Collect and place in sealable containers for
disposal. Avoid generating dust.
Environment The aquatic toxicity of calcium hydroxide is due to it's alkalinity. It is neutralised
to calcium carbonate by absorption of atmospheric carbon dioxide and is not
degraded by oxidation. Calcium hydroxide does not bioaccumulate in the
environment.
Fire and Non flammable. No fire or explosion hazard exists.
Explosion
Extinguishing Non flammable.

HEALTH HAZARDS
Health Hazard Corrosive. Use safe work practices to avoid eye - skin contact and dust generation -
inhalation. Once water is added.
Summary an inhalation hazard is not anticipated. Chronic respiratory effects are not
anticipated with over exposure at high levels due to the immediate irritant and/or
corrosive effects.
Eye Corrosive. Severe irritant upon contact with powder / dust. Over exposure may result
in pain, redness, corneal burns and ulceration with possible permanent damage.
Inhalation Corrosive. Over exposure to powder - dust(when mixing) may result in severe
mucous membrane irritation of nose and throat, coughing and bronchitis at high
levels.
Skin Corrosive. Prolonged and repeated contact with powder or wetted form may result in
skin rash and dermatitis.
Ingestion Corrosive. Ingestion may result in ulceration and burns to the mouth and throat,
nausea, vomiting, abdominal pain and diarrhoea.

PRECAUTIONS
Flammability Non flammable. May generate heat in contact with water.
Reactivity Incompatible with hydrofluoric acid (violently) and phosphorus pentoxide. Reacts
(potentially vigorously) with water generating heat and evolving calcium hydroxide.
Ventilation Do not inhale dust/powder. Use with adequate natural ventilation. Where a dust
inhalation hazard exists, mechanical extraction ventilation is recommended.

PERSONAL PROTECTIVE EQUIPMENT
PPE Wear dust-proof goggles and PVC or rubber gloves. When using large quantities or
where heavy contamination is likely, wear coveralls. Where an inhalation risk exists,
wear a Class P1 (Particulate) Respirator. At high dust levels, wear a Powered Air
Purifying Respirator (PAPR) with Class P3 (Particulate) filter or a Class P3

SAFE HANDLING
Storage Store in cool, dry area, removed from water/moisture, hydrofluoric acid,
phosphorus pentoxide and foodstuffs. Ensure packages or storage tanks are
adequately labelled, protected from physical damage and sealed when not in use.
Caution: Swells when moist and may burst containers.
Waste For small amounts: VERY SLOWLY, hydrate (add water) and then neutralise with
Disposal dilute hydrochloric acid (e.g. 6NHCI) to pH of 7-8. Dilute and flush to sewer or landfill.
For large amounts material can be readily recycled. Contact Manufacturer for
additional information.
Transport Not regulated for transport purposes.

EMERGENCY
Spillage If spilt(bulk), contact emergency services if appropriate. Wear dust-proof PVC/rubber
gloves, a Class p1 (Particulate) respirator (where an inhalation risk exists). Coveralls
and rubber boots. Clear area of all unprotected personnel. Prevent spill entering
drains or waterways. Collect and place in sealable containers for disposal. Avoid
generating dust.
Fire and Non flammable. However may generate heat upon contact with water: sufficient heat
Explosion may be generated to ignite surrounding combustible materials. Evacuate area in fire
situation and contact emergency services. DO NOT USE WATER: use dry chemical
or carbon dioxide.
Extinguishing Non flammable. Do not use water for fire fighting as contact will increase heat
generation. Use dry agent or carbon dioxide extinguishers only.
