Aluminum phosphide is a highly toxic insecticide. It must be used strictly according to the correct procedures, and all operations must be performed by professionally trained personnel under strict safety measures. Unauthorized personnel are strictly prohibited from handling it!

Operators must wear effective protective equipment such as respirators, protective goggles, rubber gloves, and long-sleeved work clothes.

2. Strictly seal the fumigation area by closing all doors, windows, and vents to ensure no gas leaks into living or working spaces.

3. After completing the dosing, all personnel should evacuate in an orderly manner immediately.

Set up prominent warning signs near the fumigation area.

5. After fumigation, the area must be thoroughly ventilated before entry, and operators must still wear full protective gear at this time.

6. Personnel without protective equipment may only enter after confirming that the phosphine concentration in the air is below the safety standard (typically 0.3 ppm) using a phosphine gas detector.

7. The residue after aluminum phosphide decomposition is mainly a white or grayish-white powder (aluminum hydroxide), which can be buried in a deep pit far from water sources and human settlements.
