Does the BBP standard apply to voluntary emergency responders?

No. In an October 22, 1992 Letter of Interpretation (LOI) OSHA states, “the definition of “occupational exposure” comprises the reasonable anticipation that the employee will come into contact with these fluids during the course of performing his or her work duties ... Employees who perform “Good Samaritan” acts are not, per se, covered by this standard, although OSHA would encourage an employer to offer follow-up procedures to an employee who experiences an exposure incident as the result of performing a “Good Samaritan” act. This is because such an action does not constitute “occupational exposure,” as defined by the standard. The key to this issue is not whether employees have been trained in first aid, but whether they are also designated as responsible for rendering medical assistance. While many workers may be trained in first aid and CPR, not all of these employees would necessarily be designated to render first aid.”
