H I would like to have the details of the Time-Weighted Average (TWA-PEL) as well as Ceiling values for hydrogen chloride and also Threshold Limit Values (TLV)?

The Occupational Safety and Health Standards Board (OSHSB) received another Permissible Exposure Limit for 8-hour Time-Weighted Average (TWA-PEL) and Ceiling values for hydrogen chloride.

The new presentation limits supplant those recorded in the General Industry Safety Orders, Section 5155, Table AC-1 Permissible Exposure Limits for Chemical Contaminants.

On the off chance that you utilize hydrogen chloride in your operations, to be in consistence, you have to guarantee that the airborne contaminant levels are kept beneath the new reasonable presentation and roof constrains either by building control measures or by utilizing the fitting individual defensive hardware (PPE).

These new breaking points consider the accessible data on the wellbeing impacts of exposures to hydrogen chloride in the work environment. They are:

Hydrogen chloride

TWA PEL
ppm
mg/m3

Ceiling Limit Units
ppm
mg/m3

Old limit(s)
5.0
7.0

New limits
0.3

ppm - Parts of contaminants per million parts of air
mg/m3 - Milligrams of substance per cubic meter of air

When dissolved in water, hydrogen chloride will form hydrochloric acid or muriatic acid, which is extensively used in various industrial as well as commercial processes such as:

Manufacturing of household cleaning products
Metal cleaning
Electroplating
Hydraulic fracturing or fracking
Leather processing
Concrete etching and clean down
pH control of water
Synthesis of inorganic chemical compounds

Threshold Limit Values (TLV) and Immediately Dangerous to Life and Health (IDLH) values
