“…This lack of experience results in differences in the perception of heat between children and adults, where expectations and experience, perception, personal preference, and feedback mechanisms related to the thermal environment (e.g., Knez, Thorsson, Eliasson, & Lindberg, 2009;Metje, Sterling, & Baker, 2008;Parsons, 2003) are more limited in children, affecting the interpretation of their physical state and subsequent adaptive behavior to avoid heat stress (Vanos, 2015). Due to many of the above-mentioned cumulative factors, children experience burns on playgrounds even in moderate midlatitude climates (Ford et al, 2011;Strong, Tahir, & Verma, 2007). Burns can occur in 3 s on solid metal surfaces with temperatures ≥60 • C (ASTM 1055(ASTM , 2014CPSC, 2010;ISO 13732, 2010;Ungar & Stroud, 2010); for plastics or nonmetallic coatings that are more insulating, higher threshold temperatures are set (e.g., ≥77 • C for plastic ISO 13732 (2010), see Table 1).…”
