Which action by a school health and wellness committee is most effective in preventing health hazards related to mercury in a school?

The most effective action for preventing health hazards related to mercury in a school is providing materials on preventing and cleaning up mercury spills to science and other teachers. This approach directly addresses the knowledge and preparedness of those who handle materials that may contain mercury. By equipping teachers with the appropriate information, they can better understand the risks associated with mercury, as well as the proper procedures to follow if a spill occurs.

This proactive measure not only helps in minimizing the likelihood of mercury exposure but also ensures that teachers can respond quickly and effectively to any incidents. Such education and resources empower staff to create a safer learning environment for students and themselves.

While installing detectors may help identify mercury levels, it does not prevent exposure or spills. Conducting safety drills can build awareness, but without specific knowledge about mercury, the drills may not be effective in addressing the unique risks associated with it. A policy against using mercury in experiments is important but does not equip teachers with the necessary procedures for dealing with existing mercury or accidents that may occur prior to the implementation of such a policy.
