Tar bases, coal, crude; Crude Tar Bases; [The reaction product obtained by neutralizing coal tar base extract oil with an alkaline solution, such as aqueous sodium hydroxide, to obtain the free bases. Composed primarily of such organic bases as acridine, phenanthridine, pyridine, quinoline and their alkyl derivatives.]

Tar bases, coal, crude; Crude Tar Bases; [The reaction product obtained by neutralizing coal tar base extract oil with an alkaline solution, such as aqueous sodium hydroxide, to obtain the free bases. Composed primarily of such organic bases as acridine, phenanthridine, pyridine, quinoline and their alkyl derivatives.] is classified as mutagenic, potentially carcinogenic. Exposure must be minimised using engineering controls (local exhaust ventilation, closed systems). Biological and medical monitoring may be required. Refer to the full Safety Data Sheet (SDS) Section 8 for occupational exposure limits.

This substance carries the signal word DANGER, indicating the more severe hazard categories under GHS/CLP. Facilities handling Tar bases, coal, crude; Crude Tar Bases; [The reaction product obtained by neutralizing coal tar base extract oil with an alkaline solution, such as aqueous sodium hydroxide, to obtain the free bases. Composed primarily of such organic bases as acridine, phenanthridine, pyridine, quinoline and their alkyl derivatives.] should ensure a written hazard communication programme, including current SDS, employee training records, and GHS-compliant labelling on all containers.
