Potential hazard analysis of standard gases

1. The logo is not clear or there is no warning mark

1) Cylinders for standard gases should bear the same warning label as pure gases. There is no domestic standard for the calculation of flammability or oxidation of standard gases. ISO 10156 provides a method that can be followed for calculating the flammability and oxidation of standard gases.

2) Standard gases shall have the same composition and concentration label as pure gases.

3) Labels inconsistent with gas or concentration should not be left, and the remaining labels from the last filling should be cleaned up.

2. standard gas valve outlet thread should follow the rules

Standard gas valve outlet thread should follow: flammable standard gas - left-hand, non-flammable standard gas - right-hand; At present, most of the standard gas valve outlet threads provided by the production plant on the market have no difference, all of them are right-handed; Standard gas and pure gas should be the same, flammable standard gas use outlet screw right turn valve, to prevent the wrong connection in the production process and customer use;

3. gas near the explosion limit, or after the explosion in the process of filling range, there is no limit to the concentration and the pressure as a standard gas producers, not only provides the concentration of the final product to the customer in the combustible, explosive) under the floor, but also in the process of filling to ensure the safety of operating personnel, for after the explosion range of standard in the process of filling gas, shall be computed through strict control of filling pressure and sample order, strict operation procedure, the operator should be trained, training qualified after filling the gas.

Potential hazards of liquid mixtures

In addition to following the same rules as gaseous mixtures, consider:

1. the filling can not be overloaded;

2. Confirm that there is no room in the cylinder;

3. electronic scale to calibrate;

4. The material of the siphon should be compatible with the composition of the filling pipe.

Monitoring of environmental gases in the production process

Due to the wide variety of standard gases, complex composition, flammable and explosive and toxic and harmful gas leakage, may produce accidents, so the indoor installation of alarm is a necessary condition to achieve safe production, safe production, prevention.

In short, in the process of standard gas preparation, it is necessary to study the prepared standard gas, develop reasonable filling technology and safe operation procedures, provide necessary safe production conditions, put safety production in the first place, reduce personal injury and property loss, so as to create a harmonious social environment.
