Procedure For HCl Gas Calibration And Bump Testing - Honeywell
HCl is a reactive gas It is very well known that due to its acidic and polar properties HCl can either react with components of a gas-delivery system (tubing valves regulators etc ) or be adsorbed by the system As a result the target gas does not reach an AreaRAE’s sensor in the specified concentration during a calibration or bump test |

Is HCl a reactive gas?
- HCl is a reactive gas. It is very well known that due to its acidic and polar properties, HCl can either react with components of a gas-delivery system (tubing, valves, regulators, etc.) or be adsorbed by the system. As a result, the target gas does not reach an AreaRAE’s sensor in the specified concentration during a calibration or bump test.
How dangerous is hydrogen chloride?
- Hazard Rating Key: 0=minimal; 1=slight; 2=moderate; 3=serious; 4=severe ?Hydrogen Chloride can affect you when inhaled. ?Hydrogen Chloride is a CORROSIVE CHEMICAL and contact can severely irritate and burn the skin and eyes with possible eye damage. ? Contact with liquid Hydrogen Chloride may cause frostbite.
What is HCl used for?
- g., steel pickling). Also known as muriatic acid, HCl is used by masons to clean finished brick work, is also a common ingredient in many reactions, and is the preferred acid for catalyzing organic processes.
Is HCl a hazardous air pollutant (HAP)?
- Facilities handling HCl at concentrations below 37% are not subject to this rule. Hydrochloric acid is listed in Section 112(b) of the Clean Air Act Amendments of 1990 as a Hazardous Air Pollutant (HAP).
