How much Difluoroethane is dangerous?

How much Difluoroethane is dangerous?

cracking of the skin. DANGEROUS FIRE HAZARD. No occupational exposure limits have been established for 1,1-Difluoroethane. However, it may pose a health risk.

What is Difluoroethane intoxication?

Abstract. 1,1-Difluoroethane (DFE) is a halogenated hydrocarbon used as a propellant in products designed for dusting electronic equipment and air brush painting. When abused, inhaled DFE produces intoxication and loss of muscular coordination.

Is Difluoroethane carcinogenic?

In a 2-year bioassay, HFC-152a was not carcinogenic to rats at inhalation exposure levels up to 25,000 ppm.

What is the boiling point of Difluoroethane?

-24.9 °C
1,1-Difluoroethane/Boiling point

What happens if you breathe in Difluoroethane?

Acute adverse effects of difluoroethane inhalation include loss of consciousness, frostbite at mucosal surfaces, rhabdomyolysis, and global myocardial hypokinesis. At the cardiac myocyte, fluorinated hydrocarbons alter potassium and calcium currents, leading to dysrhythmias and prolonged atrial refractory time [4].

Can compressed air cause frostbite?

The liquid inside canned air can cause frostbite when the skin is exposed to a steady stream. This can vary from an intense burning sensation to serious physical injuries such as skin cracking, and damage to muscles, blood vessels and nerves.

What happens if you breathe in difluoroethane?

Is Difluoroethane a fluorocarbon?

This colorless gas is used as a refrigerant, where it is often listed as R-152a (refrigerant-152a) or HFC-152a (hydrofluorocarbon-152a). It is also used as a propellant for aerosol sprays and in gas duster products….1,1-Difluoroethane.

Is difluoroethane a greenhouse gas?

Greenhouse Gases (GHGs) Another popular HFC propellant is HFC-152a (difluoroethane), which has an array of industrial and commercial uses. Both HFC-134a and HFC-152a are GHGs.

How long does mild frostbite last?

After rewarming, the skin will be discoloured and blistered, and will eventually scab over. If the frostbite is superficial, new pink skin will form beneath the discoloured skin and scabs. The area usually recovers within 6 months.

Why does AXE spray burn?

“It is an aerosol burn caused by the pressurized gas within the spray cooling quickly. The decrease in temperature freezes the skin causing frostbite. This type of frostbite is very similar to a burn. Evidence of the burn may appear immediately or may surface over a number of days.

Is Difluoroethane a greenhouse gas?

Why is difluoroethane on the right to know list?

1,1-Difluoroethane is a colorless and odorless gas which is used as a liquefied compressed gas. It is used as a cooling agent, as an aerosol propellant, and in the manufacture of other chemicals. f 1,1-Difluoroethane is on the Right to Know Hazardous Substance List because it is cited by DOT, DEP, IRIS and EPA.

What happens when you inhale 1, 1-difluoroethane?

f Inhaling 1,1-Difluoroethane can irritate the lungs. Higher exposures may cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency. f High exposure can decrease the amount of Oxygen in the air. This can cause headache, dizziness, lightheadedness and passing out. f Prolonged or repeated exposure can cause drying and

What was the original IDLH for 1, 1 dichloroethane?

Human data: None relevant for use in determining the revised IDLH. Basis for revised IDLH: The revised IDLH for 1,1-dichloroethane is 3,000 ppm based on acute inhalation toxicity data in animals [Carpenter et al. 1949; Mueller 1925]. 1. Carpenter CP, Smyth HF Jr, Pozzani UC [1949].

How does 1, 1-difluoroethane affect the central nervous system?

1,1- Difluoroethane can cause central nervous system depression after inhalation exposures. Symptoms of such over-exposure can include drowsiness, nausea, headache, fatigue, and weakness. At high concentrations, the gas can act as an asphyxiant, by displacing oxygen.
