Safety and health in laboratory
The laboratory is a workplace to conduct scientific research. The laboratory is also used as a means of experiments for student is a supportive done in class. Chemistry laboratory as a means of chemistry laboratory course can not be separated from the chemicals and laboratory activities that require the attention of safety.
In carrying out students activities in the chemistry laboratory, must be considered regarding safety. Chemistry laboratories should be sought is a safe place to work and free from fears of accidents. The student and laboratory officer jointly responsible for administering occupational health and safety in the laboratory, in order to do experiments effectively and efficiently.
- Chemical safety guidelines data
The term for data guidelines for chemicals that are used internationally is the material safety data sheets (MSDS). In the MSDS guidelines, there are four signs that must be considered. Blue columns indicate the level of a chemical hazard to health. Red columns indicate the level of a chemical hazard to the fire. Yellow columns showed level chemical reactivity. White columns is a special sign for some chemicals.
- First aid in the laboratory
Accidents in the laboratory are not expected to occur even if the pattern has been applied to K3. Therefore, in doing laboratory work, students and officers need to have knowledge about the steps to the taken in case of accidents. First aid (P3K) is knowledge that must be possessed by every students as the prevention of accidents are more severe impact before getting intensive treatment from the doctor.
Here are some kinds of accidents in the laboratory and handling./
If the body burns due to heat, basting with livertran ointments, butter of pikrat 3% acid aolution. If the wound is large enough flush with 1% bicarbonate solution and immediately the it to the nearest clinic.
- Skin exposed to concentrated acid
If the skin is exposed to splashing sulfuric acid, or nitric acid, immedialety wiped with tissue paper and than wash with water and sodium bicarbonate. Drain and spread with ointment livertran.
- skin exposed to string base
immediately wash with tap water that much, then with 1% acetic acid solution and rinse again with water. After dry rubbing with ointment livertran.
- Skin exposed to bromine water
Immediately wash with benzene and basting with the glycerine. After a while washing the rest of Glycerin with water and spread with ointment livertran.
- Skin exposed to organic substances
If the skin is exposed to the corrosive organic substance, wash it with alcohol, then wash again using soap and warm water.
- Eyes affected by acid/base
- If dilute acid, wash the eye with a solution of sodium bicarbonate 1% using eye wash equipment.
- If a concentrated acid, first wash with water as much as possible, then wash with a solution of sodium bicarbonate 1%.
- If the eyes exposed to alkali, washing with water and 1% boric acid solution.
- Solids, liquids, and toxic gases
- If the toxic substances into the month but not swallowed. Substance is released immediately and rinse with water as much as possible.
- If the acid solution ingested, immediately drink water as much as possible. Then drink water slurry of lime or magnesia and pure milk. If a strong base which is swallowed, immediately drink as much as possible, then drank a solution of diluted vinegar, lemo juice, lactic acid, after that drink whole milk.
- Arsenic of mercury compounds are swallowed, promptly drink salt solution made by dissolving one teaspoon of salt in a glass of water.
