Is R-410A considered a hazardous material?
This substance is not classified as dangerous according to Directive 67/548/EEC or 1999/45/EC. Most important adverse effect: Rapid evaporation of the liquid may cause frostbite. Vapour is heavier than air and can cause suffocation.
What is the chemical composition of R-410A?
50%CH2F2/50%CHF2CF3
R-410A/Formula
What is the primary safety concern when working with R-410A?
It is poisonous and flammable. The major safety concern with R-410A compared to most other common refrigerants is that: R-410A operates at much higher pressures.
What is the specific gravity of R-410A refrigerant?
1.06
Specific gravity
| Specific gravity | |
|---|---|
| R-409A | 1.21 |
| R-410A | 1.06 |

Is it bad to breathe 410A?
EYES: Liquid contact can cause severe irritation and frostbite. Mist may irritate. INHALATION: R-410A is low in acute toxicity in animals. When oxygen levels in air are reduced to 12-14% by displacement, symptoms of asphyxiation, loss of coordination, increased pulse rate and deeper respiration will occur.
Is R-410A a Class 1 refrigerant?
Is R-410A Toxic or Flammable? No. Just like R-22 the new R-410A is rated as an A1 classification by ASHRAE. A means non-toxic and 1 means non-flammable.
What is the replacement for R410A?
R-32
Daikin has announced R-32 as the ideal choice to replace R-410A in the Americas and around the world for many of its key products. Carrier has announced its intention to use R-32 for scroll chillers and R-454B for other residential and commercial products.
Why is R410A so expensive?
Unfortunately for homeowners, the price of R410a has increased significantly over the past few months. There are two major reasons why this has happened. The first reason is a simple matter of supply and demand. As R22 is phased out, the demand for R410a increases, and producers haven’t been able to keep up.
What is the operating pressure of R-410A?
A normally operating R-410A system with the same condensing temperature of 120 degrees and a 45 degree evaporator saturation temperature will have a high side pressure of 418 psig and a low side pressure of 130 psig.
What should 410A pressures be at 75 degrees?
217 PSIG
Likewise, an R-410A recovery bottle with a surrounding air temperature of 75°F should have an internal pressure of 217 PSIG.
Which is more flammable R32 or R-410A?
R32, better known as difluoromethane, is an organic gas, much like R410A. With an ODP of 0, the two gases are also equally harmless to the ozone layer. Still, R32 has a GWP of 675, which is significantly lower than those of R22 and R410A. It’s a grade A2 gas, which means it is mildly flammable.
Is R-410A refrigerant bad?
Even though R410A isn’t an ozone-depleting product, refrigerant is a potentially dangerous chemical. Only a qualified HVAC professional should handle this refrigerant or repair your air conditioner.
