This 600g tin of Calcium Reagent is for use with the Speedy range of moisture measurement pressure vessels.
The calcium carbide reagent used with the Speedy tester is a hazardous product that must be handled with care by the user and with consideration for the environment.
This 600g tin of Calcium Reagent is for use with the Speed range of moisture measurement pressure vessels.
The calcium carbide reagent used with the Speedy tester is a hazardous product that must be handled with care by the user and with consideration for the environment.
Users of the Speedy must be familiar with the Speedy Moisture Test Procedure detailed in this manual.
Users must also follow calcium carbide transportation, storage, handling and disposal guidelines in accordance with local regulations and/or the calcium carbide Material Safety Data Sheet (MSDS). Users should be familiar with the hazard identification, first aid measures, fire-fighting measures, accidental release measures, personal protection measures, physical and chemical properties, stability and reactivity, toxicological information, and ecological information as given in the MSDS
NOTE!
Unopened Tins have a foil seal and screw cap, which means shelf life is virtually unlimited, however, once opened the Calcium Carbide does absorb moisture and oxygen and if used/opened regularly can affect the moisture readings.
For Court work and critical work it is advised to only use NEW tins at all times.
General
Molecular formula: CaC2
CAS No: 75-20-7
Physical data
Appearance: grey or black solid with a garlic-like odour
Melting point: 2300 C
Vapour density: 2.2 (air = 1)
Density (g cm-3): 2.22
Water solubility: decomposes
Stability
Reacts violently with water liberating highly flammable gas (acetylene). Do not use water if this material is involved in a fire.
The equation for Calcium Carbides reaction with water is
CaC2 + 2 H2O → C2H2 + Ca(OH)2
Therefore, 1 gram of CaC2 gives 349ml of acetylene.
Incompatible with moisture, water, strong oxidizing agents, alcohols, hydrogen chloride, magnesium.
Toxicology
Harmful if inhaled, swallowed and in contact with skin. Contact with skin may cause severe irritation or burns
Risk phrases
R15 Contact with water liberates extremely flammable gases.
R20 Harmful by inhalation.
R21 Harmful in contact with skin.
R22 Harmful if swallowed.
R38 Irritating to skin.
Personal protection
Safety glasses, good ventilation. Do not use near water.
