An innocent looking but aging and brittle 5L plastic pink parafin

carefully. Had it ruptured I would be dead. Specialist disposal
required. The HF *safety* film is notorious for causing lost time

full of cyanide but I think that HF beats that. I remember seeing
(probably the same?) HF safety film - probably one of the grossest
things I have ever seen!
