Carcinogenicity of 6-Bromo-2-tetralone(4133-35-1) hasn't been listed as a carcinogen by  NTP, IARC,ACGIH, or CA Prop 65.You can see actual entry in RTECS for complete information.

Polymerization of the 6-Bromo-2-tetralone(4133-35-1) is stable under normal temperature and pressure conditions,and you must not take it with strong oxidizing agents .And also need to prevent it to broken down into hazardous decomposition products:hydrogen bromide, oxides of nitrogen,carbon dioxide,carbon monoxide.
6-Bromo-2-tetralone(4133-35-1) is hazardous,so the first aid measures should be known .Such as:
Skin: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids.The get medical aid.
Inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.And as soon as to get medical aid.
Ingestion: Wash mouth out with water,and get medical aid.
