Communication Contents: The Safety Board is pleased that the IAFC published articles in its newsletter On Scene, which served to advise its membership of the circumstances of these two accidents and the associated recommendations to prevent recurrence. With respect to H-91-10 in particular, we are also aware through correspondence with the U.S. Fire Administration and the National Fire Protection Association (NFPA) that NFPA standards on fire apparatus and on fire department occupational safety and health now require that every responder be provided with a designated seat and that all responders be seated and belted before the apparatus moves. Accordingly, Safety Recommendations H-91-7 through -10 and P-93-23 are classified "Closed-Acceptable Action."
