IMCA, International Marine Contractors Association. This association of worldwide member commercial diving companies has created a set of safe practice guidelines for commercial diving companies to follow. It is only a set of guidelines and is up to each individual diving company to determine if they will follow them. However, over the years clients, insurers and diving companies have adopted IMCA guideline as the industry standards.
A similar set of voluntary best/safe practice operational standards could also be created by an association of craft distillers.
