Classification

Not classified as hazardous under the United Nations GHS. No ingredient is classified as hazardous: see section 3. Published sheets of gypsum building plaster give the same result.

Label elements

No pictogram, no signal word and no hazard statement.

Dust

Dust of the powder can irritate the eyes, the nose and the throat.

Heat when the plaster sets

Wet plaster becomes hot while it sets. Plaster that sets around a hand, a finger or another body part can cause severe burns. Never let plaster set around a body part.

Skin

Long or repeated contact with the powder or with wet plaster can dry the skin.

Type of product

Mixture.

Calcium sulphate hemihydrate

CaSO₄·½H₂O. CAS number 10034-76-1. The main ingredient.

Natural constituents

Typical for gypsum plaster (published sheets): the gypsum rock can bring small quantities of clay, limestone and quartz.

Additives

Small quantities of additives that control the setting time and the workability. None is classified as hazardous.

Crystalline silica (quartz)

CAS number 14808-60-7. Natural gypsum can contain a small quantity of quartz. The content of this product is not tested.

Hazardous ingredients

None. No ingredient is classified as hazardous.

Eyes

Do not rub. Rinse with much clean water for at least 15 minutes with the eyelids open. Remove contact lenses if this is easy. Get medical advice if the irritation continues.

Skin

Wash with soap and water. Use a skin cream if the skin is dry.

Plaster on the body

If wet plaster is around a hand or another body part, remove it immediately and wash before it becomes hard. If plaster has become hard on the body or the skin is burnt, cool with water and get medical help immediately.

Breathing

Move the person to fresh air. Get medical advice if a cough or irritation continues.

Swallowing

Rinse the mouth and give water to drink. Do not cause vomiting. Get medical advice if a large quantity was swallowed or the person feels unwell.

Note for the doctor

Treat the symptoms.

Flammability

The product does not burn and does not feed a fire.

Extinguishing media

Use the media that are correct for the fire around the product.

Special hazards

The packaging can burn. Above about 1450 °C calcium sulphate breaks down into calcium oxide and sulphur oxides.

Advice for fire-fighters

Wear the usual protective clothing and breathing apparatus for a building fire.

Personal precautions

Do not make dust. Wear the protection given in section 8.

Clean-up

Sweep or vacuum the dry powder and put it in a dry container. Do not use compressed air.

Wet material

Let wet plaster set, then remove it as a solid.

Environment

Keep the powder and wet plaster out of drains. Plaster sets under water and can block a drain.

Handling

Open and empty the bag with care to keep dust low. Put the powder into the water, not the water onto the powder. Do not eat, drink or smoke during the work. Wash your hands after the work.

Lifting

A bag weighs 20 kg. Lift it with a straight back and bent knees.

Storage

Store in the closed bag, in a dry and covered place, off the floor and away from damp walls.

Shelf life

1 year, in the closed bag, in a dry store, off the floor.

Stack height

Stack the bags on a level and dry base. A guide from Indian site practice for bagged cement (IS 4082): not more than 10 bags high.

Limits in India

The Second Schedule of the Factories Act 1948 gives no limit for calcium sulphate. It gives limits for dust that contains quartz. Respirable dust: 10 ÷ (% respirable quartz + 2) mg/m³. Total dust: 30 ÷ (% quartz + 3) mg/m³.

Calcium sulphate dust

Literature values, 8-hour average. ACGIH: 10 mg/m³ (inhalable dust). OSHA: 15 mg/m³ (total dust) and 5 mg/m³ (respirable dust).

Quartz, respirable dust

Literature values, 8-hour average. ACGIH: 0.025 mg/m³. OSHA: 0.05 mg/m³.

Ventilation

Work with good ventilation. Use local extraction where the powder is emptied or mixed in a closed room.

Breathing protection

Wear a dust mask (particle filter) when there is dust.

Eye protection

Wear safety goggles when you empty bags, mix, or work above your head.

Hand and skin protection

Wear waterproof gloves for wet plaster. Wear clothing that covers the arms and legs.

Hygiene

Wash the skin after the work. Change clothing that is full of dust.

Form

Dry powder.

Colour

White.

Odour

None.

pH (mixed with water)

6.5 (factory lab). Range: 6 to 8.

Bulk density of the powder

780 kg/m³, powder as packed (factory lab). Range: 600 to 800 kg/m³.

Melting point

Not applicable. The material breaks down before it melts.

Flash point

Not applicable. The product is a mineral powder that does not burn.

Flammability and explosion

Not flammable. The dust is not combustible.

Solubility in water

Slightly soluble: about 2 g in one litre at room temperature (literature value for calcium sulphate). The powder reacts with water and sets.

Decomposition

Above about 1450 °C, into calcium oxide and sulphur oxides (literature value for calcium sulphate).

Stability

Stable when it is kept dry.

Reaction with water

The powder reacts with water, sets hard and gives off heat. This is the intended use. Factory lab test: the mix reaches 50.7 °C while it sets.

Conditions to avoid

Water and damp air during storage.

Incompatible materials

No dangerous reaction is known with common building materials. Published sheets for calcium sulphate tell you to keep it away from strong acids.

Hazardous decomposition products

None in normal use. Above about 1450 °C: calcium oxide and sulphur oxides.

Tests on this product

No toxicological test was made on this product. The lines below come from the literature on calcium sulphate.

Acute toxicity

Literature value for calcium sulphate: oral LD50 (rat) more than 2000 mg/kg. This is a low toxicity.

Eyes

Dust can cause irritation by rubbing.

Skin

Literature: calcium sulphate did not irritate the skin in tests and did not cause a skin allergy. Long or repeated contact can dry the skin. Plaster that sets on the skin becomes hot and can burn.

Breathing

Dust can irritate the nose and the throat.

Long-term effects

Literature: no long-term effect of calcium sulphate dust is known. Respirable quartz dust, breathed in for a long time, can cause the lung disease silicosis. IARC puts it in Group 1 (it can cause cancer in humans). Section 3 gives the status of quartz in this product.

General

Calcium sulphate is a mineral that occurs in nature as gypsum. Calcium and sulphate are natural parts of water and soil.

Persistence and degradability

Not applicable. The material is inorganic.

Ecotoxicity

No test was made on this product. Literature for calcium sulphate: tests with fish, water fleas and water plants showed no toxic effect.

Precaution

Do not put large quantities into drains, rivers or ponds. The plaster sets and it raises the sulphate content of the water.

Product

Let unused wet plaster set. Dispose of set plaster and dry powder as construction waste, in agreement with the local rules.

Do not

Do not put large quantities together with food waste or other waste that rots. In wet conditions without air, gypsum can give hydrogen sulphide gas.

Packaging

Empty the bag fully. Dispose of it or recycle it in agreement with the local rules.

Rules in India

Set plaster and plaster debris: the Construction and Demolition Waste Management Rules 2016. An empty bag of plastic: the Plastic Waste Management Rules 2016. The local body can add its own rules.
