Gases. The provisions of paragraph 3. of Appendix 3 to Annex 4a to the 07 series of amendments to this Regulation apply, where they are relevant.
Gases. Many of the gases used in the laboratories -‐ Ar, He, N2, H2 – are neither poisonous nor corrosive, but all are asphyxiant; some can even pose an explosion or a fire hazard. It is important to be cautious when handling gases. If you need to use any gas for any application, you must first discuss the matter with the lab staff. Be careful: gas bottles contain gas at very high pressure. Opening the main valve of the bottle when it is not connected to a pressure reducer is very dangerous. Therefore you are not allowed to exchange the gas bottles if you have not been instructed on how to do this. Before moving any gas cylinder: close the cylinder valve and refit the valve protection cap. Always try to use ramps, trolleys and forklifts instead of manual handling.

Gases. The aging process of certain building materials many times create unwanted and undesired gases and other contaminants in condominiums, both new and used. Also, since the increased awareness and need for energy conservation, the International Building Code has enabled condominiums to be created which allow less outside air infiltration and therefore trap these unwanted gases in different degrees depending on how each person lives within his/her Unit. Measurements of such unwanted gases are reported to be in the air we breathe and can affect our health, and as such Seller recommends frequent airing of Buyer's Unit by simply opening the windows to introduce outside air that is uncontaminated by such trapped gases. By making such a recommendation, Seller does not undertake any obligations to Buyer in regard to the effects that any such contaminants may have on Buyer, Xxxxx's family, or other occupants of the Unit.

2.2. Calibration and span gases
Gases. The grading of the soil and other elements created by nature, as well as building materials developed by humans, many times create unwanted and undesired gases and other contaminates in homes and residential buildings, both new and used. Also, since energy conservation has become a concern, there is a need to build homes and residential buildings that are more airtight. As a result, these homes and residential buildings trap unwanted gases in different degrees depending on how each person lives within their home or such residential building. To date measurements of such unwanted gases (such as the radon gas described below and carbon dioxide) are reported as parts of the air they occupy. Since the quality of air a person breathes can affect his or her health, Seller recommends frequent airing of a Unit to introduce fresh air uncontaminated with such gases.
