What are the precautions one should take when handling mercury? I'll mark you the brainliest
Answers
Never use a mercury thermometer in a laboratory oven.
Do not leave open containers of mercury in the laboratory. If used in a bubbler, the exhaust should go up a vertical tube to eliminate splashing and should be vented to a fume hood.
Do not keep excess mercury – purchase only amounts that will be completely used.
Use a glass, plastic or steel tray to contain any spills that might occur.
Glass or plastic vessels should have a secondary steel or plastic container around them in case the vessel fails.
Do not use mercury where it could contact a hot surface and vaporize.
Avoid inhaling mercury vapor and use suitable gloves when working with it.
Put mercury waste in a special waste container, do not combine it with other wastes and do not dispose of it down a sink.
Do not wear gold or silver jewelry when working with mercury.
As always, read the material safety data sheet (MSDS) for mercury before using it.
Access to mercury should be restricted to a locked cabinet or room, and only used by those have been given suitable and sufficient training.
Answer:
Inhalation: Take precautions to ensure your own safety before attempting rescue (e.g. wear appropriate protective equipment). Move victim to fresh air. If breathing is difficult, trained personnel should administer emergency oxygen. DO NOT allow victim to move about unnecessarily. Symptoms of pulmonary edema may be delayed. If breathing has stopped, trained personnel should begin artificial respiration (AR). If the heart has stopped, trained personnel should start cardiopulmonary resuscitation (CPR) or automated external defibrillation (AED). Avoid mouth-to-mouth contact by using mouth guards or shields. Immediately call a Poison Centre or doctor. Treatment is urgently required. Transport to a hospital.
Skin Contact: Avoid direct contact. Wear chemical protective clothing if necessary. Quickly take off contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Quickly and gently blot or brush away excess chemical. Wash gently and thoroughly with lukewarm, gently flowing water and non-abrasive soap for 5 minutes. Call a Poison Centre or doctor. Thoroughly clean clothing, shoes and leather goods before reuse or dispose of safely.
Eye Contact: Avoid direct contact. Wear chemical protective gloves if necessary. Quickly and gently blot or brush chemical off the face. Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for 5 minutes, while holding the eyelid(s) open. If irritation or pain persists, see a doctor.
Ingestion: Have victim rinse mouth with water. Immediately call a Poison Centre or doctor.
First Aid Comments: If exposed or concerned, see a doctor for medical advice. Some of the first aid procedures recommended here require advanced first aid training. All first aid procedures should be periodically reviewed by a doctor familiar with the chemical and its conditions of use in the workplace.
Note to Physicians: Some jurisdictions specifically regulate mercury and require a complete medical surveillance program. Specific information should be sought from the appropriate government agency in your jurisdiction.
