Are there any dangers while handling cobalt dichloride?

I use a desiccant named *Drierite* to remove water from air in experiments. It is composed of $98\%\ \ce{CaSO4}$ and $2\%\ \ce{CoCl2}$. Every once in a while the Drierite gets saturated with water vapor and it must be dried out so it can be used again. 


According to the manufacturer you put the chemical in a lab oven, set to $230\ ^\circ\mathrm{C}$ until it turns blue. The cobalt dichloride $\ce{CoCl2}$ is an indicator that turns blue when dry and pink/purple when saturated. One of my coworkers noted that cobalt dichloride is a carcinogen, and now he wants me to stop heating it in the lab oven because of the vapor it is giving off that we are breathing. 


* Could cobalt dichloride give off anything that would cause a person harm espcially when heated to $230\ ^\circ\mathrm{C}$?


I have looked at the safety data sheet but it is not very helpful. It does say that cobalt dicloride is a carcinogen but not how or when it is transferred.
