WARNING Acetylene, stored in a free state under pressure greater than 15 psi (103.4 kPa), can break down from heat or shock, and possibly explode. Under pressure of 29.4 psi (203) kPa), acetylene becomes self-explosive, and a slight shock can cause it to explode spontaneously. CAUTION Although acetylene is nontoxic, it is an anesthetic, and if present in a sufficiently
