Общее описание

Colorless gas with a faint, ether-like odor at high concentrations. Boiling point 38°F. Shipped as a liquefied compressed gas.

Профиль реактивности

dichlorotetrafluoroethane is incompatible with the following: Chemically-active metals such as sodium, potassium, calcium, powdered aluminum, zinc & magnesium; acids; acid fumes .

Угроза здоровью

Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating, corrosive and/or toxic gases.

Пожароопасность

Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.

Профиль безопасности

A ddly toxic irritant; narcotic in high concentrations. An asphyxiant. Reacts violently with alcohol. When heated to decomposition it emits toxic fumes of Fand Cl-

Возможный контакт

This material is used as a refrigerant and also as a propellant gas

Перевозки

UN1958. 1,2-Dichloro-1,1,2,2-tetrafluoroethane or Refrigerant gas R-114, Hazard Class: 2.2; Labels: 2.2- Nonflammable compressed gas. Cylinders must be transported in a secure upright position, in a well-ventilated truck. Protect cylinder and labels from physical damage. The owner of the compressed gas cylinder is the only entity allowed by federal law (49CFR) to transport and refill them. It is a violation of transportation regulations to refill compressed gas cylinders without the express written permission of the owner

Несовместимости

Keep away from welding and hot metals; decomposes, forming hydrogen chloride and hydrogen fluoride. Reacts with acids and acid fumes forming highly toxic chloride gases. Keep away from chemically active metals: sodium, potassium, calcium, powdered aluminum; zinc, and magnesium. Attacks some plastics and coatings.

Утилизация отходов

Return refillable compressed gas cylinders to supplier. Incineration after mixing with combustible fuel. Use flue gas scrubber.
