  MSC/Circ.848 and MSC.1/Circ.1267 permit halocarbon agents to be used in concentrations up to the No Observed Adverse Effect Level (NOAEL) calculated on the net volume of the protected space at the maximum expected ambient temperature without additional safety measures. In no case should halocarbon agents be used at concentrations above the Lowest Observed Adverse Effect Level (LOAEL). These Guidelines prescribe the recommended protocol for determining the referred-to NOAEL and LOAEL levels.
