Title:
Sulphuric Acid, 98% (Select Grade) / Page:
1 of 3
1. GENERAL
1.1DescriptionEssentially sulphuric acid, H2SO4, in the form of a clear, oily, corrosive liquid.
1.2PropertiesDensity at 20 C : 1,83 g/cm3
Boiling point at 101,3 kPa : 330 C
Specific heat at 20 C : 1,42 J/g C
Viscosity at 25 C : 22 mPa.s
Vapour pressure at 55 C : < 1,2 Pa
1.3ToxicityThe material is very toxic (Rating 4 according to "Clinical Toxicology of Commercial Products"). The probable lethal dose (to humans) is 50 to 500 mg/kg of body mass.
TWA OEL-RL : 1 mg/m3
(According to "Occupational Health and Safety Act", Act 85 of 1993, as amended)
1.4HazardsThe material is extremely corrosive to body tissue and contact with concentrated acid results in rapid destruction of tissue, causing severe burns. Ingestion may cause severe injury and can result in death. Repeated contact with dilute solution causes dermatitis. Inhalation of concentrated vapours and mists results in serious damage to lung tissue and can cause unconsciousness. Eye contact may result in serious damage and total loss of vision. The material is a very powerful acidic oxidizer which can ignite or even explode on contact with many materials; i.e. acetic acid, carbides, chlorates, fulminates, perchlorates, etc. It reacts with water and steam evolving considerable heat. When heated the material emits highly toxic fumes. Dilute acid is corrosive to most metals with evolution of flammable hydrogen.
1.5Special PrecautionsFull protective clothing and a face shield must be worn when handling the material. Avoid ingestion, inhalation, skin and eye contact. Store away from combustibles, strong oxidising or reducing materials. Always add acid slowly to diluents.
Refer to Material Safety Data Sheet 104
