(b) Systems requiring a permit and containing any refrigerant ~rrhich is harmful to health and. the vapors of ~•rhich are not readily apparent through odor or irritating effect shall have added to such refrigerant a suitable leak detecting agent ~,rhich trill give ~r~arriing before dangerous concentrations are reached. This restriction shall not apply to systems employing carbon dioxide.
