1 Identification of the substance and the company

1.1 Substance

Name of the substance: gypsum flooring plaster
Commercial name: Plâtre à Plancher
Company :

2 composition

Mix of sulphate of calcium and hydroxide of calcium, possibly added with silico-calcareous sand.
Component contributing to the danger: calcium hydroxide 1305-62-0 Xi.R 41: inferior to 5 %

3 Identification of the dangers

The contact of lime on the cornea of the eye causes serious ocular lesions

4 First aid

* Contact with the eyes:
To quickly flush (as far as possible on the premises) the eye with running water (under low pressure ) during at least 15 minutes. maintain the eyelids largely open (to avoid the reflex movement of closing them).
Turn and move the eyes in all directions, while taking care to eliminate the specks in the conjunctival channels.
The rapidity of intervention is of primary importance because the absence of care in the hour which follows the accident can involve a diminution of sight, whereas the immediate processing avoids any after-effect.
The nurse or the doctor will decide of the need for consulting an ophthalmologist. If the pain or the tingling persists, it is highly advised to consult a specialist.
* Inhalation: to withdraw the subject from the contaminated zone and to place him in open fresh air.
To consult a doctor if necessary.
* Contact with the skin: To clean with water and soap.
To remove soiled clothing.
To consult a doctor if necessary.
* Ingestion: To immediately rinse the mouth .

11 toxicological Informations

Non-toxic substance.
Irritating substance for the eyes.

12 ecological Informations

Lime is a basic substance which increases the pH. Although it is very useful to correct the acidity of water, an excess can be harmful for the watery life.
However the effect is not remanent: in contact with the carbonic anhydrite of the air, lime is quickly neutralized in the form of calcium carbonate.
The plaster is a neutral and soluble substance.
Its action on the environment could come only from an excess waste at the same time large and persistent. The plaster and lime can be evacuated in the sewers with a water excess.
Its action will be beneficial for residual water and the muds that they contain.

13 Considerations relative to elimination
