Classification

Not classified as hazardous under the United Nations GHS. Published sheets of paper-faced gypsum boards give the same result. The maker states: no hazardous substances.

Label elements

No pictogram, no signal word and no hazard statement.

Dust

Dust from cutting, sawing or sanding can irritate the eyes, the nose and the throat.

Weight and size

One board weighs 15.3 kg and is 1.83 m long. Two persons carry a board. A stack that is not flat can slide or fall.

Type of product

Article: a solid board.

Core: calcium sulphate dihydrate (gypsum)

CaSO₄·2H₂O. CAS number 10101-41-4. The maker states: 100% natural gypsum.

Face and back paper: cellulose

CAS number 9004-34-6.

Typical composition

Typical for paper-faced gypsum board (published sheets): more than 80% gypsum and less than 10% paper by mass. The rest is starch and small quantities of additives such as foam and dispersing agents. This is not the maker's figure for this board.

Crystalline silica (quartz)

CAS number 14808-60-7. Typical for paper-faced gypsum board (published sheets): natural gypsum can contain a small quantity of quartz. The content of this board is not tested.

Hazardous ingredients

None. The maker states: no hazardous substances.

Eyes

Do not rub. Rinse with much clean water for at least 15 minutes with the eyelids open. Get medical advice if the irritation continues.

Skin

Wash with soap and water.

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. Get medical advice if the person feels unwell.

Injury

For a cut, or an injury from a board that fell, give the usual first aid and get medical help.

Flammability

The gypsum core does not burn. The face and back papers can char and burn.

Extinguishing media

Water spray, foam, dry powder or carbon dioxide, as is correct for the fire around the product.

Special hazards

In a fire the paper gives smoke and carbon oxides. Gypsum gives off water vapour when it is heated. 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.

Broken boards

Collect the pieces by hand. Wear gloves.

Dust

Sweep or vacuum the dust. Do not use compressed air. Wear the protection given in section 8 if there is much dust.

Environment

No special measure. Keep dust and pieces out of drains.

Handling

Two persons carry one board, on its long edge. Do not carry a board flat above the head. Wear gloves and safety shoes.

Cutting

Cut the board with a knife (score, then snap) where this is possible. This makes less dust than a saw.

Do not stand on a board

Typical for paper-faced gypsum board (published sheets): a board does not carry the weight of a person between the members of the frame.

Storage

Store the boards flat, in a dry and covered place, on a level floor with supports across the full width. Do not stand the boards on edge.

Stack

A pallet holds 70 to 80 boards. Keep the boards on the pallet as supplied. Put a pallet only on a level floor.

Limits in India

The Second Schedule of the Factories Act 1948 gives no limit for calcium sulphate or for paper dust. 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).

Paper dust (cellulose)

Literature values, 8-hour average. ACGIH: 10 mg/m³. 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

Cut and sand with good ventilation. Use a tool with dust extraction for power sawing or sanding.

Breathing protection

Wear a dust mask (particle filter) for sawing and sanding.

Eye protection

Wear safety goggles for cutting, and for all work above your head.

Hand and foot protection

Wear gloves and safety shoes to carry and to fix the boards.

Form

Solid, flat board.

Colour

Face paper ivory. Back paper brown. Core white to grey (typical for gypsum board).

Odour

None.

Size

1220 × 1830 × 12 mm.

Weight

15.3 kg for one board. This is about 6.9 kg for one square metre (worked out from the weight and the size).

Density of the board

About 570 kg/m³ (worked out from the weight and the size of one board).

pH

About 7 (typical for gypsum board, from published sheets).

Flash point

Not applicable. The product is a solid.

Solubility in water

The gypsum core is slightly soluble: about 2 g in one litre at room temperature (literature value for calcium sulphate). The paper is not soluble.

Decomposition

Gypsum gives off water vapour when it is heated. Above about 1450 °C calcium sulphate breaks down into calcium oxide and sulphur oxides (literature value).

Stability

Stable in dry storage.

Conditions to avoid

Water during storage. Strong heat.

Incompatible materials

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

Hazardous decomposition products

None in normal use. In a fire: see section 5.

Tests on this product

No toxicological test of this board is on record. The lines below come from the literature on gypsum and from published sheets of paper-faced gypsum board.

Acute toxicity

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

Eyes

Dust can cause irritation by rubbing.

Skin

Literature: gypsum did not irritate the skin in tests and did not cause a skin allergy. Long contact with dust can dry the skin.

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. A board that is fixed and painted gives off no dust.

General

Gypsum is a natural mineral. Calcium and sulphate are natural parts of water and soil. Paper is made of plant fibre.

Ecotoxicity

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

Recycling

The maker states that the board can be recycled.

Precaution

Keep dust and waste pieces out of drains and water.

Product

Recycle clean off-cuts where a collection exists. If not, dispose of them 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. Do not burn waste board.

Packaging

Dispose of or recycle the tape and the pallet material in agreement with the local rules.

Rules in India

Off-cuts and board debris: the Construction and Demolition Waste Management Rules 2016. Plastic packaging: the Plastic Waste Management Rules 2016. The local body can add its own rules.

Classification

Not dangerous goods for transport by road, rail, sea or air (UN Model Regulations, ADR, RID, IMDG Code, IATA).

UN number, class, packing group

None.

Road transport in India

No UN class applies. The rules for dangerous or hazardous goods of the Central Motor Vehicles Rules 1989 do not apply.

Precaution

Transport the boards flat, fully supported, dry and covered. Secure the stack so that it cannot slide.
