II. Component/Composition Information
Pure Product
| Harmful Component | Concentration | CAS No. |
| ---- | ---- | ---- |
| Ammonium Hydrofluoride | [X]% | 1341-49-7 |

III. Hazard Overview
Hazard Category
Skin Corrosion/Irritation, Category 1B; Severe Eye Damage/Eye Irritation, Category 1; Hazardous to the Aquatic Environment - Acute Hazard, Category 1; Hazardous to the Aquatic Environment - Long-Term Hazard, Category 1.

Invasive Route
Inhalation, Ingestion, Transdermal Absorption.

Health Hazard
Strong irritation and corrosive to the skin. Inhalation of its dust or smoke can cause respiratory irritation and bronchitis, and in severe cases, pulmonary edema and respiratory distress syndrome can occur. Accidental administration can cause burns to the digestive

IV. First aid measures
Skin contact
Immediately remove contaminated clothing and rinse with plenty of flowing water for at least 15 minutes. Seek medical attention.

Eye contact
Immediately lift the eyelids and rinse thoroughly with plenty of flowing water or normal saline for at least 15 minutes. Seek medical attention.

Inhalation
Quickly leave the scene to a fresh place of air. Keep the respiratory tract unobstructed. If breathing difficulties, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.

Ingest
Gargle with water, and give milk or egg whites. Seek medical attention.

5. Firefighting measures
Hazardous characteristics
Decompose by heat, releasing toxic nitrogen oxides and fluoride flue gas. React with acids to release corrosive hydrogen fluoride gas.

Hazardous combustion products
Nitrogen oxides, hydrogen fluoride.

Fire extinguishing methods
Firefighters must wear full-body acid and alkali fire-fighting clothing and air breathing apparatus to extinguish the fire. Move the container from the fire site to an open area as much as possible. Spray water to keep the fire site container cool until the fire is extinguished.

Fire extinguishing agent
Mist water, foam, dry powder, carbon dioxide.

VI. Emergency treatment of leaks
Emergency operations
Isolate the leaking contaminated area and restrict access. It is recommended that emergency personnel wear dust masks and anti-acid and alkali clothing. Do not come into direct contact with leaks. Small leaks: Avoid dust and collect in a dry, clean, covered container with a clean shovel. Large leaks: Collect and recycle or transport to a waste disposal site for disposal.

VII. Operation disposal and storage
Operational precautions
Closed operation to provide adequate local exhaust. Prevent dust from being released into the air of the workshop. Operators must be specially trained and strictly follow the operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety protective glasses, rubber acid and alkali clothing, and rubber acid and alkali gloves. Avoid dust generation. Avoid contact with acids and alkalis. When handling, it should be handled lightly to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment. Harmful substances may remain in empty containers.

Storage precautions
Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. Package is sealed. It should be stored separately from acids, alkalis, and edible chemicals, and should not be mixed. The storage area should be equipped with suitable materials to contain leaks.

VIII. Contact Control/Personal Protection
Occupational Exposure Limits
| China MAC (mg/m ³) | No Standards |
| ---- | ---- |
| Former Soviet Union MAC (mg/m ³) | 1 (as F) |
| TLVTN | No Standards |
| TLVWN | No Standards |

Monitoring Methods
Ion Selective Electrode Method; Fluoride Reagent-Lanthanum Salt Colorimetry.

Engineering Control
is tightly sealed to provide adequate local ventilation.

Respiratory Protection
A self-priming filter dust mask must be worn when possible contact with its dust. An air respirator should be worn during emergency rescue or evacuation.

Eye Protection
Wear chemical safety glasses.

Body Protection
Wear rubber acid and alkali resistant clothing.

Hand Protection
Wear rubber acid and alkali resistant gloves.

Other Protection
Smoking, eating and drinking are prohibited at the work site. After work, shower and change clothes. Maintain good hygiene habits.
