No architect or engineer may be held liable for personal injury, wrongful death, property damage, or other loss related to any architectural, structural, electrical, mechanical, or other professional design service provided by the architect or engineer, voluntarily or without compensation, at the request or approval of a national, state, or local public official in response to a declared national, state, or local emergency caused by a tornado, fire, explosion, collapse or other similar disaster or catastrophic event. This section applies to services rendered within ninety days following the end of the declared emergency, disaster, or catastrophic event unless extended by executive order of the Governor. Limited liability under this section does not apply if the injury, death, or damage is the result of gross negligence or willful or wanton misconduct. For the purposes of this section compensation does not include reimbursement for expenses.
