CONSTRUCTION

• Temporary heating systems are also often necessary on construction sites to prevent frozen water pipes and to "maintain temperatures necessary for materials to set (such as adhesives)."
• Portable heaters are necessary on winter construction months to "keep materials (such as paint or putty) from freezing overnight, thaw the ground and allow concrete to cure, and — most importantly — keep... workers healthy and happy."
