What is Calcium Hydride? Calcium Hydride CaH2 is an organic substance that has a molal weight of 42.10. These crystals are grayish-white and easily deliquescent. They can be used as reducing agent, desiccants or chemical analysis reagents. Also known as a colorless orthorhombic crystal, industrial products can be gray, powdered or orthorhombic. It is sensitive to moisture. It doesn’t react with nitrogen or chlorine in the air at room temperatures. However, at high temperature, it can generate calcium nitride (or calcium chloride) and calcium oxide. When it is in contact with water, it releases hydrogen and decomposes. It can also produce hydrogen and calcium oxide when it reacts with ethanol. The reduction effect of metal oxides on sodium hydride and lithium hydride is much stronger.
What is the danger of calcium hydride to human health?
Calcium hydride is irritating to the mucous tissues, upper respiratory system, eyes and skin. It can cause death after inhalation due to spasms and inflammation. Contact with it can cause burning sensations, wheezing or laryngitis.
Protective measures against calcium hydride
Respiratory Protection: If you think you might be exposed to poisons or dust, wear a hooded electric air filter respirator. Wearing a self contained breathing apparatus is recommended when needed.
Eye protection: Protected with respiratory protection.
Wear protective clothing to protect your body from chemicals.
Wear rubber gloves as a hand protection.
Other: Smoking at work is strictly forbidden. Attention to personal hygiene.
What should I be doing if I accidentally get in contact with calcium hydroide?
Contact with skin: Remove all contaminated clothing as soon as possible and rinse thoroughly under running water for a minimum of 15 minutes. Seek medical attention.
Eye contact: Remove the eyelid as soon as possible and thoroughly rinse with running water for at least 15 min. Seek medical attention.
Inhalation – leave the scene immediately to get fresh air. Airways should be kept clear. Oxygen is recommended if breathing becomes difficult. Immediately give artificial respiration if breathing stops. Seek medical attention.
Ingestion: Rinse your mouth out with water if you accidentally consume milk or egg yolk. Seek medical attention.
What should I do if there is a leakage of calcium hydride?
Access to the contaminated area should be restricted. Remove the fire source. Emergency personnel are advised to wear self-contained respiratory apparatus and acid-alkali proof overalls. Do not touch the leaking liquid. Use non-sparking, dust-free tools to collect the small amount. Place the container in a safe location. Leakage in large quantities: Cover the leakage with canvas and plastic sheet to reduce dispersion. Contact the relevant technical departments to determine the removal technique.
