The MSDS for joint compound says, as you might expect, that it is non-flammable. It is not a risk, unless you consider the dust putting out the fire a risk.
Is joint compound fireproof?
What is the fire rating of joint compound? Joint compound does not have a fire rating by itself, but does meet ASTM C475. When fire testing a wall the fire rating is not for individual products, but for all the system components together. USG Joint Compounds are used in numerous fire-tested assemblies.
Is drywall mud fire rated?

Can you mud over fire tape?
The surface of the Fire Tape is treated with silicone and mud or paint will not adhere to it.

Once the Zinsser is dry, a latex paint or mud can be applied.

This single coat is commonly referred to as fire taping.
At what temperature can you apply drywall mud?
The recommended temperatures for drywall and paint vary by manufacturer and the type of material in question. In general, the best temperature before, during, and 48-hours after the final drywall compound application is 55°F. The temperature should not fall below 50°F or exceed 95°F.

Will drywall mud dry when it’s cold?
Drying Times In a room that is 70 degrees Fahrenheit, for example, joint compound can take approximately 12 days to fully dry at 98 percent humidity. Cold weather also increases drying time, and joint compound should not be used at temperatures below 55 degrees Fahrenheit.

What is fire resistant drywall?
Fireproof drywall is the common term; its industry name is Type X drywall. The thickness of this drywall is 5/8-inch, including all layers. Glass fibers are added to the board to help it retard fire. Also, because it is denser than normal gypsum-and-paper drywall, it takes longer for the fire to degrade it.
