When handling sealants, it is crucial to keep them away from sources of ignition. Sealants often contain volatile organic compounds (VOCs) and other flammable ingredients that can pose a fire hazard if they come into contact with flames or sparks. By ensuring that sealants are used in a safe environment, away from any potential ignition sources, the risk of fire is significantly reduced. This precaution is especially important in aerospace applications, where safety standards are extremely high due to the potential consequences of a fire or explosion in confined or sensitive environments.

In contrast, using protective creams for hand safety does not directly address the most pressing danger associated with sealant materials, and working in a dimly lit area could increase the likelihood of spills or mishandling the materials. Mixing sealants without gloves can lead to skin irritation or other health risks, which is why proper protective equipment is typically recommended, rather than avoiding it altogether. Overall, maintaining a safe environment free of ignition sources is the most critical precaution when managing sealants.
