| Resumen |
To protect workers against airborne solvent vapours, the threshold limit value (TLV) and the maximum allowable concentration (MAC) are taken into account. The TLV is the mean concentration of the solvent in the atmosphere at which, except in hypersensitive cases, no disorders are found in subjects exposed throughout the whole duration of their work. The MAC is found by multiplying the TLV by a variable factor; it represents a limit which should never be exceeded. For some very toxic solvents, TLV=MAC. A synoptic table shows the TLVs set by the American Conference of Governmental Industrial Hygienists (ACGIH) for the most common solvents; a description is given of a few methods for analysing solvent vapours in air. Definition of the biological MAC, found by analysising the blood, urine and faeces of the person exposed, and indication of its value for several solvents. The necessity of continually checking the health status of exposed workers is stressed. |
