2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
Ingestion of large quantities (>50ml) may cause diarrhoea and vomiting. Several other studies have shown that large quantities of glycerine can be administered orally to experimental animals and man without the appearance of adverse effects. Eye
May cause irritation, however eye-application to rabbit eyes has produced no significant injury. Skin
May cause irritation and defatting of the skin. Inhaled
Due to its low vapour pressure glycerine is not considered to be an inhalation hazard at normal room temperature. At elevated temperatures the fumes may cause irritation and dehydration of the mucous membranes. 2.2 Health Effects - Chronic
No information available.
2.3 First Aid
Swallowed
Administer water to dilute the glycerine, call medical attention because of hazards involved in ingestion of large quantities.
Eye
Rinse thoroughly with water. Eyelids should be held away from the eyeball to ensure thorough rinsing. Seek medical advice if irritation develops.
Skin
Remove contaminated clothing. Seek medical advice if irritation develops. Launder clothing before reuse. After contact with skin, wash immediately with plenty of water.
Inhaled
This is only possible by exposure to HOT product. Move to fresh air, rest. Half upright position, loosen clothing. Oxygen or artificial respiration if there is difficulty in breathing. Seek medical advice after significant exposure.
First Aid Facilities
Ensure that an eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
Treat symptomatically based on judgement of doctor and individual reactions of patient.
2.6 Toxicity Data
Oral LD50 = 12600 mg/kg (Rat)
3. PRECAUTIONS FOR USE
3.1 Exposure Standards
Worksafe recommends : TWA 10 mg/m3 (as mist)
3.2 Engineering Controls
Ensure adequate ventilation to maintain exposure levels below standards.
3.3 Personal Protection
No special protection required when handled at normal ambient temperatures. At elevated temperatures, wear thermal gloves, chemcial safety goggles or face shield, and a suitable apron for thermal protection.
