Part 4: first aid measures

4.1 description of necessary first aid measures inhalation

inhalation

Inhalation: Immediately leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.

Skin contact

Skin:Immediately flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, Immediately call a physician and be prepared to transport the victim to a hospital for treatment.

Eye contact

eyes: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. Immediately transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

Ingestion

Ingestion: Do not induce vomiting,If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and Immediately call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT Induce vomiting.Immediately transport the victim to a hospital.

Part 5: fire fighting measures

5.1 extinguishing media

Fire extinguishing method and agent

Fires involving this compound should be controlled using a dry chemical, carbon dioxide, foam or Halon extinguisher.

5.2 special hazards from this substance or mixture

No data available

5.3 precautions and protection measures for fire fighting

In case of small-scale fire, masks shall be worn to prevent the inhalation of toxic gas. In case of fire, the emergency response system shall be started in time to evacuate to the upper air outlet, and the local fire department shall be contacted to put out the fire.

Part 6: Leakage Emergency Treatment

6.1 personnel protection measures, protective equipment and emergency disposal procedures

1. Start the emergency response system first after leakage. 2. Before leakage treatment, wear safety protection shoes, safety protection gloves (anti acid and alkali gloves are required for strong acid substances), and wear corresponding protective masks according to the inhalation risk.

For personal protection, see Part 8.

6.2 environmental protection measures

Refer to the treatment method of Fande biochemical waste to prevent harm to the environment. After treatment, the waste shall be treated by a qualified waste treatment structure to avoid environmental pollution. 

6.3 storage, removal methods and disposal materials of leaked chemicals

The leaked chemicals shall be treated according to the treatment method of Fande biological chemical waste. Before treatment, the leaking area shall be enclosed with chemical absorbent rock wool to form a "cofferdam" to prevent the leakage from expanding.

6.4 reference to other parts

See section 13 for disposal.

Part 7: handling and storage

7.1 precautions for safe operation

Please wear masks, gloves and other protective articles during use to avoid contact with skin, inhalation and accidental ingestion.

See Section 2.2 for precautions.

7.2 conditions for safe storage, including any incompatibility

It is unable to provide detailed data for the time being. Try to avoid mixed storage with other compounds and storage in dark and ventilated places.

Personal protective equipment

Eye protection

Please use equipment tested and approved by official standards such as NIOSH (USA) or en 166 (EU) for eye protection.

Skin protection

Take out by hand: gloves must be inspected before use. Please use proper methods to remove the gloves (do not touch the outer surface of the gloves), and avoid any skin parts contacting the product. After use, please handle the contaminated gloves carefully according to relevant laws and regulations and effective laboratory rules and procedures. Please wash and dry your hands.

The selected protective gloves must meet the specifications given in regulation (EU) 2016 / 425 and the en 374 standard derived from it.

Full contact

Material: NBR

Minimum layer thickness 0.11 mm

Solvent penetration time: 480 minutes

Splash protection

Material: NBR

Minimum layer thickness 0.11 mm

Solvent penetration time: 480 minutes

If applied in solvent form or mixed with other substances, or under conditions different from those specified in en 374, please contact the supplier of gloves approved by EC. This recommendation is only suggestive and must be evaluated and confirmed by an industrial hygiene expert familiar with the specific situation our customer plans to use. This should not be interpreted as providing approval for any particular usage method.

Body protection

Choose physical protection measures according to the type, concentration and quantity of hazardous substances and specific workplace. The type of protective equipment must be selected according to the concentration and quantity of hazardous substances in the specific workplace.

respiratory system protection

There is no need to protect breathing. To protect against dust damage, use N95 (US) or P1 (EN 143) dust masks. Respirators use respirators and parts that have been tested and passed government standards such as NIOSH (US) or cen (EU).

Control of environmental exposure

Do not let the product into the sewer.
