Annex 1: List of limit values for pollutants in the working atmosphere

Offshore petroleum activities are subject to the limit values with safety factors as mentioned in Section 36 of the Activities Regulations. Activities at onshore facilities (see Section 6(e) of the Framework Regulations) shall be planned with safety factors reflecting limit values.

The list includes comments as follows:

A:	Chemicals to be treated as provoking allergic reactions or other hypersensitivity in the eyes or respiratory organs, or to be treated as provoking allergic reactions in contact with skin.
E:	The EU has adopted a recommended limit value for the substance.
G:	The EU has adopted a binding limit value for the substance.
H:	Chemicals that can be absorbed through the skin.
K:	Chemicals to be treated as carcinogenic.
M:	Chemicals to be treated as mutagenic.
R:	Chemicals to be treated as harmful to reproduction.
S:	The short-term exposure limit: the average concentration of a chemical substance in an employee's breathing zone that must not be exceeded over a given reference period. The reference period is 15 minutes unless otherwise specified.
T:	The ceiling value: a momentary value indicating the maximum concentration of a chemical substance in the breathing zone, which must not be exceeded.
