R23

Packing: Recycled steel cylinder—40L R-23 refrigerant, alias R23, Freon 23, F23, F-23, HFC23, HFC-23. Since R-23 belongs to HFC substances (non-ODS substances Ozone-depleting Substances), it does not destroy the ozone layer at all. It is an environmentally friendly refrigerant recognized and recommended by most countries in the world, and it is also one of the mainstream environmentally friendly refrigerants.

产品描述

Packing: Recycled steel cylinder—40L

R-23 refrigerant, alias R23, Freon 23, F23, F-23, HFC23, HFC-23. Since R-23 belongs to HFC substances (non-ODS substances Ozone-depleting Substances), it does not destroy the ozone layer at all. It is an environmentally friendly refrigerant recognized and recommended by most countries in the world, and it is also one of the mainstream environmentally friendly refrigerants.

Scope of application

As a widely used ultra-low temperature refrigerant, R-23 is a very effective and safe CFC-13 (R13, R-13, Freon 13, Freon-13) and R- Substitutes for 503, mainly used in environmental test chambers/equipment (cold and thermal shock testers), freeze dryers/freeze dryers, ultra-low temperature refrigerators or freezers, blood bank refrigerators, biochemical test chambers and other cryogenic equipment (including scientific research refrigeration, medical refrigeration, etc.), the cryogenic grades that are commonly used in these cascade refrigeration systems. At the same time, trifluoromethane can also be used as a gas fire extinguishing agent, which is an ideal substitute for halon 1301. It has the characteristics of cleanliness, low toxicity and good fire extinguishing effect.

The effect on the environment

1. Health hazards

Route of entry: Inhalation.

Health Hazards: Exposure can cause headache, nausea and vomiting, and has narcotic effects.

2. Toxicological information and environmental behavior

Toxicity: It is a low toxicity category.

Acute toxicity: rats inhaled 20% × 2 hours, survived; guinea pigs inhaled 50-80% (continuous inhalation in oxygenated environment), survived

Hazardous properties: Non-flammable. Heated decomposition of the highly toxic fumes.

Combustion (decomposition) products: hydrogen fluoride.

3. On-site emergency monitoring methods:

4. Laboratory monitoring methods:

5. Environmental standards:

The maximum allowable concentration of harmful substances in the air of the former Soviet Union workshop is 1000mg/m3

Emergency treatment and disposal methods

Emergency release treatment

Quickly evacuate the personnel from the leaked contaminated area to the upper wind, isolate them, and strictly restrict access. It is recommended that emergency responders wear self-contained positive pressure breathing apparatus and general work clothes. 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.

Protective measures

Respiratory system protection: When the concentration of material in the air is high, it is recommended to wear a self-priming filter gas mask (half mask).

Body Protection: Wear general work clothes.

Hand Protection: Wear general work protective gloves.

Other: Avoid high concentration inhalation. Access to tanks, confined spaces or other high-concentration areas must be supervised.

first-aid

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

Extinguishing method: This product is not flammable. Cut off the air supply. Cool containers with water spray and move containers from fire to an open area if possible.
