All parties involved in the manufacturing, distribution, and servicing of the forklift have some responsibility to warn of the products of combustion hazard. I can't currently put my fingers on specific laws and regulations. I am sure that in this litigious society, however, there are many lawyers ready and waiting with case law and legal precedent to establish the following responsibilities in civil cases:

The forklift engine manufacturer has a responsibility to inform the forklift manufacturer and end user of the product of combustion hazard. This information should be in the engine maintenance and repair manual. I would recommend it also be included in the product literature.

The forklift manufacturer has a responsibility to inform its forklift distributors/dealers and forklift end users of the product of combustion hazard. This information should be in its forklift operating, safety, and repair manuals. I would recommend it also be included in the product literature.

The forklift distributor/dealer and its sales personnel have a responsibility to inform the buyer or prospective buyer of the product of combustion hazard. I recommend such information be part of the sales contract.

Service technicians have a responsibility to inform management if they observe forklifts being operated in a manner that could result in a product of combustion incident. I recommend any such action be documented.

Company trainers (and independent trainers) have a responsibility to adequately instruct the forklift operators in the product of combustion hazard. I recommend that this topic, and all other training topics covered, be thoroughly documented.
