Application

As a refrigerant, it is mainly used in air conditioning, industrial and commercial refrigeration, chillers and other industries, and is used to prepare R404A, R407C, R410A, R507 and other refrigerants to replace R22, R12, etc. It can also be used as a fire extinguishing agent to replace some halon series fire extinguishing agents. HFC-125 can be used as refrigerant and is an important component of mixed working medium, used to replace CFC-502 and HCFC-22; used as fire extinguishing agent to replace Halon-1211 and Halon-1301.

 

Storage and transportation

Store in a cool, dry and ventilated non-combustible warehouse. Keep away from fire, heat and direct sunlight. Should be stored separately from oxidizing agents. The lighting, ventilation and other facilities in the storage room should be riot-proof, and the switch should be located outside the warehouse. Prohibit the use of mechanical equipment and tools that are prone to sparks. Always pay attention to check the container for leaks. Carrying is to bring the safety helmet and shockproof rubber ring of the cylinder to prevent the cylinder from being collided and damaged. The packaging method is steel gas cylinders or tank trucks.

Health hazard

Low toxicity substance, very low inhalation toxicity

 

First-aid

Quickly leave the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If you stop breathing, give artificial respiration immediately and seek medical attention.

 

Protective measures

Respiratory system protection: Generally, no special protection is required, and special protection is generally not required when exposed to high concentrations, but it is recommended to wear a self-priming filter gas mask (half mask) under special circumstances. 

Eye Protection: When necessary, wear chemical safety goggles.

Body Protection: Wear anti-static overalls.

Hand Protection: Wear general work protective gloves.

Others: Smoking is strictly prohibited at the work site. Access to tanks, confined spaces or other high-concentration areas must be supervised.

 

Emergency release treatment

Quickly evacuate personnel from the leaked contaminated area to the upper wind, and immediately isolate them, and strictly restrict access. Cut off the source of ignition. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and fire protection clothing. Cut off sources of leaks as much as possible. Reasonable ventilation, accelerate the diffusion. The leaking container should be properly handled, repaired and inspected before use.
