The third part: an overview of the risk:
Summary of emergencies: OSHA hazard communication defines the substance as harmless.
Signal word: attention
Health hazards: prolonged exposure to dust can stimulate body tissues, inhaling dust can cause irritation and coughing of the nose and throat. It can also cause acute anaphylaxis in some people.
Physical properties: solid state
Olfactory threshold: no
Potential health effects:
Exposure routes: eye contact, digestive tract intake, skin contact
Symptoms and signs of acute exposure: severe cough and / or skin irritation
Skin contact: in most cases, slight contact with skin powder does not cause irritation. However, long time contact can cause stimulation. When there is contact, rinse the powder with soapy water.
In most cases, mild contact with powdered aqueous solution does not cause irritation. If contact with water solution, wash out with soapy water. It should be avoided to keep contact with water easily and steadily.
Inhalation: inhalation of powder can cause irritation and coughing in the nose and throat, resulting in chest discomfort. Some individuals, however, are very allergic to the substance. If they breathe in dust and powder, they should be transferred to fresh air immediately. If you stop breathing, take artificial respiration and see the doctor immediately.
Eye contact: rinse immediately with plenty of water for at least 15 minutes. Sometimes wash the upper and lower eyelids. This situation should be observed immediately.
Intake of digestive tract: it is not possible for digestive tract ingestion. However, if there is an ingestion of the digestive tract, first the victim has two cups of water and then immediately induce vomiting.
Note: do not give a loss of consciousness to the patient with liquid.
Overview of chronic health effects:
Inhalation: prolonged inhalation of dust can cause irritation of the nose and throat, resulting in coughing.
Skin contact: long exposure to dry powder from aqueous solution of dry powder can cause skin irritation finally.
Exposure can aggravate the following conditions:
Some people who are very allergic to this substance.
The fourth part: first aid measures:
Take appropriate precautions to ensure your health and safety before you do your best to rescue and provide first aid measures. For special information, please refer to the emergency summary section of the MSDS.
Inhalation: if symptoms occur, immediately transfer the victim to fresh air. If breathing stops, take artificial respiration. Immediate medical observation.
Eye contact: rinse immediately with plenty of water for at least 15 minutes. Sometimes wash the upper and lower eyelids. If this is the case, medical observation should be taken immediately.
Skin contact: rinse immediately with plenty of soapy water. If irritation persists and aggravates, seek medical attention.
Alimentary tract intake: if there is an ingestion of the digestive tract, first give the victim two cups of water and then induce vomiting immediately. Caution: do not give oral liquid to patients with loss of consciousness. Immediate medical observation.
The fifth part: fire protection measures
NFPA rate: unknown
Classification of flammability: unknown
Flash point: no
Spontaneous combustion temperature: unknown
Limit of combustion: low value: no high value: no
Harmful combustion products: the substance is considered noncombustible. However, under fire conditions, it may decompose and release sulfur dioxide.
The condition of avoidance: unknown
Fire extinguishing agent: small fire: according to the surrounding low environment, use the appropriate extinguishing agent.
Fire: according to the surrounding environment, use the appropriate extinguishing agent.
Fire extinguishing method
Protective equipment / clothing: suitable respirator and protective clothing should be used according to the surrounding conditions. Spray water is used to cool the container exposed to it.
Direction: use suitable methods for substances in the surrounding environment.
Other content: the substance is considered to be nonflammable. However, under fire conditions, it may decompose and release sulfur dioxide.
The sixth part: emergency treatment for external leakage
Leakage reaction: recovery and retention for reuse or treatment. Leakage should not be allowed to flow into a sewer or environment.
The number of nitrogen needs to be reported: refer to the 15 part of the relevant laws and regulations.
The seventh part: operation disposal and storage
Protection: protect your skin with rubber gloves, especially when handling dry powder. Safety glasses should be worn when handling dry powder and cleaning negatives in aqueous solution. When large quantities of solutions are used when cleaning the negatives, we suggest wearing suitable laboratory aprons and installing a safety indicator and eyewash near them. After each use of the product, wash thoroughly with soap and water and clean contaminated clothing before reuse.
Remove a small amount of powder from the storage container. If overflow occurs, collect spillage powder into the waste container. Keep away from sewers, rainwater drains, surface water and soil.
Neutralizing solvent: no
Storage: keep the container dry. Keep away from overheated environment and oxidizing agents. The container is closed to prevent pollution. It is hoped that the container should be kept tightly closed, so as to prevent moisture from entering the container and causing powder agglutination.
The eighth part: contact control and individual protection
Engineering control: if the user produces dust and odour during operation, ventilation is avoided to avoid aggregation.
Inhalation: use suitable respirators in areas where the concentration of air exceeds the limit of contact.
Skin: wear protective clothing such as long sleeves or laboratory coat, especially when handling powder.
Eyes: wear safety glasses when handling dry powder and cleaning negatives in aqueous solution. These operations are easy to splash some solutions into the eye. This is very pertinent to those who use a microscope, because a microscope technician dislikes wearing safe eyes in a fine microscope. If microscope technicians are under your control and guidance, make sure that they wear safety glasses while cleaning the negatives.
