Urea Phosphate(UP)--Tech.Grade &Food Grade

1. Health and Safety Precautions

• Skin Contact Protection

Urea phosphate has a certain degree of hygroscopicity. Direct contact with skin may cause local dryness and irritation due to moisture absorption. When handling, wear nitrile or neoprene gloves and long-sleeved protective clothing to avoid exposing skin. If accidental contact occurs, immediately flush the contact area with plenty of running water for at least 15 minutes. If redness, swelling, itching, or other discomfort occurs, seek medical attention immediately.

• Eye Protection

Urea phosphate powder or solution splashed into the eyes will cause severe irritation, resulting in conjunctival congestion and pain. Impact-resistant goggles or a full-face mask must be worn during operation. If eye contact occurs, immediately lift the eyelids and flush continuously with plenty of water or saline solution for 15-20 minutes. Seek medical attention as soon as possible. Avoid rubbing your eyes during this time.

• Respiratory Protection

Dry urea phosphate powder is easily generated as dust. Inhalation can irritate the nasal, pharyngeal, and respiratory mucosa, causing symptoms such as coughing and dry throat. When performing dust-generating operations such as feeding and mixing, it must be carried out in a fume hood or well-ventilated area, and a dust mask (KN95 or higher) must be worn. Avoid prolonged inhalation of its dust without protection.

• Prevention of Accidental Ingestion

Urea phosphate is not edible. Ingestion will irritate the digestive tract, causing symptoms such as nausea, vomiting, and abdominal pain. Wash hands promptly after handling. Eating, drinking, and smoking are strictly prohibited in the work area. The product must be stored in a sealed container, away from food, beverages, and animal feed, and the packaging must be labeled with "Non-edible" and "Chemical Product" warnings. If accidentally ingested, do not induce vomiting. Immediately drink plenty of warm water to dilute the substance and seek medical attention with the product label.

2. Storage and Transportation Safety Precautions

• Storage Requirements

- Store in a cool, dry, and well-ventilated warehouse, away from fire and heat sources. The warehouse temperature should ideally be controlled below 30℃, and the relative humidity should not exceed 75%.

- Urea phosphate is hygroscopic and prone to clumping; therefore, it requires sealed, moisture-proof packaging (such as woven bags lined with plastic film) to prevent direct contact with air. When stacking, the bottom should be elevated to maintain a distance of at least 10cm from the ground to prevent moisture absorption.

- It is strictly forbidden to store with strong alkalis, strong oxidizers, or corrosive substances, such as sodium hydroxide and sodium hypochlorite, to prevent chemical reactions that could generate harmful substances.

- The storage area must be equipped with appropriate spill response equipment, such as brooms, dustpans, and leak-proof mats.

• Transportation Requirements

- Transport vehicles must be kept dry and clean. Rainproof tarpaulins or plastic film can be laid inside the vehicle to prevent product moisture absorption. During transportation, the vehicle must be covered with a tarpaulin to avoid rain and sun exposure.

- Handle with care during loading and unloading to prevent packaging damage and powder leakage. It is strictly forbidden to transport with strong alkalis, strong acids, or other hazardous chemicals.

- Transportation routes must avoid densely populated areas such as residential areas and schools, and comply with relevant regulations for the transportation of hazardous materials (if transported as ordinary chemicals, local transportation standards must be confirmed).

3. Leakage Emergency Handling

• For small leaks, immediately collect the leaked material into a sealed container using a dry broom or shovel and dispose of it properly; do not discard it indiscriminately; avoid flushing the leaked material into sewers to prevent water pollution.

• For large leaks, first establish a warning zone and prohibit unauthorized personnel from entering; use impermeable mats to contain the leak area to prevent spread, and then collect and transfer the material; handling personnel must wear full protective equipment (protective clothing, gloves, goggles, dust masks).

4. Environmental Safety Precautions

• Although urea phosphate has low environmental toxicity, large-scale entry into water bodies can still lead to eutrophication and affect aquatic ecosystems. Production wastewater must be treated to meet standards before discharge; direct discharge into rivers, lakes, and other natural water bodies is strictly prohibited.

• Waste urea phosphate packaging must be collected and disposed of in a centralized manner and must not be discarded at will; expired or scrapped products must be entrusted to a qualified hazardous waste treatment unit for disposal and must not be buried or burned without authorization.
