2. Field of application |
|
2.1
This Official Mexican Standard regulates in the entire
national territory and applies to the workplaces that:
|
|
a)
Perform specific processes of:
|
|
1)
Extraction of petroleum; |
|
2)
Extraction of natural gas; |
|
3)
Storage and distribution of natural gas; |
|
4)
Production of liquid petroleum gas (LP gas);
|
|
5)
Storage and distribution of liquid petroleum gas (LP
gas); |
|
6)
Production of petrochemicals, or |
|
7)
Refining of crude petroleum and basic petrochemicals, or |
|
b)
Handle hazardous chemical substances in critical
processes and equipment, in equal or greater volumes
than the threshold quantities stipulated in the Appendix
A of this Standard. |
|
2.2
The quantification of the hazardous chemical substances
must be done according to one or more of the following
criteria: |
|
a)
The installed storage capacity and/or the process of the
hazardous chemical substance in the workplace, and/or |
|
b)
The quantity of hazardous chemical substances present as
raw materials and/or finished product warehoused and/or
in process. |
|
2.3
The workplaces remain excluded from the compliance to
this Standard that: |
|
a)
Handle hazardous chemical substances in critical
processes and equipment, in amounts less than those than
those listed in Appendix A of this Standard;
|
|
b)
Warehouse flammable liquids in atmospheric tanks that
are maintained below boiling point, without requiring
cooling or refrigeration; |
|
c)
Use hydrocarbons only as fuels for their internal
consumption; |
|
d)
Sell gasoline or gas to the end user, or
|
|
e)
Make retail sales of hazardous chemical substances or
products that contain them. |
-------------------------------------------------------
|
Appendix A |
|
Threshold quantities of hazardous chemical substances
|
|
A.1
In order to determine the threshold quantity of each one
of the hazardous chemical substances present or
available in the workplace, the following must be
considered: |
|
1)
The storage containers of raw materials and pipes;
|
|
2)
The train of interconnected equipment considering all
the equipment and their pipes; |
|
3)
The transport pipe and the storage container of finished
product, and |
|
4)
Temporary warehouses. |
The following table
contains the chemical substances in the workplace that are regulated
by this Standard - The last column contains the previous threshold
amounts from NOM-028-STPS-2004 for your comparison.
NOM-024-STPS-2004 is the current standard until June 2014, but the
new Standard implies a lot of new procedures, records, and training
- I advise an immediate review and study of the new Standard in
order to adapt your program before the deadline in 2014. *Glenn
