Yes, the rule deals with consequences of testing at 0.04 or greater and actions taken. The requirement of the rules for testing 0.02 - 0.039 is only removal from the safety sensitive position duties for 8 hours or until retested below 0.02. Company policies may differ significantly. The rules require the company to provide each employee with their policies and procedures with respect to meeting the requirements of the rules, in addition to materials which explain the alcohol misuse prevention requirements. You should also be given the identity of a contact person knowledgeable on the company's alcohol misuse program and its specifics.
Action is based on the actual reading only .
In addition those testing between 0.02 and 0.039 must be removed from safety sensitive function for at least 8 hours or until another breath test indicates a result less than 0.02. As noted above most companies' policies will differ from that within the rules. I would like to be able to self-test. DOT is currently considering allowing several individual, self contained testing apparatus to be used. These devices will be obtainable by individuals at reasonable cost.
