When using a flame-supplying operation, automatic sprinkler heads should be?

Using a flame-supplying operation, it's crucial to maintain safety standards, especially regarding automatic sprinkler heads. Covering them with non-combustible barriers is important because it protects the sprinkler system from interference and potential damage during operations that involve flames. The barriers ensure that the sprinkler heads remain functional and effective in the event of an emergency.

Sprinklers need to be protected from heat and debris that could be generated during flame operations, as well as any possible contaminants that could lead to malfunction. If these sprinkler heads were left uncovered, they could be rendered ineffective in suppressing a fire if it were to occur.

By covering them with non-combustible barriers, you are ensuring that they are safe from direct exposure to flame and heat, thereby maintaining their operational integrity and readiness to function properly in an emergency situation. This practice aligns with safety protocols designed to minimize fire risks in environments where flame operations are conducted.
