If you read the proposed rule, there is mention of tamper resistance requirements and compliance with third party standards which were previously not enforced. It does seem a bit concerning. For example: (f) Tamper resistance. (1) A portable generator system for controlling CO exposure shall be tamper resistant. The system is considered tamper resistant when any part that is shorted, disconnected, or removed to disable the operation of the system prevents the engine from running. In addition, all parts, including wiring, which affect proper operation of the portable generator system for controlling CO exposure, must be (a) permanently sealed or (b) not normally accessible by hand or with ordinary tools. It is permissible for different parts of the portable generator system for controlling CO exposure to meet either option (a) or (b), provided all of the different parts meet at least one of these two options.
