Résumé de l’enjeu	Dans notre province, nous vérifions et activons les dispositifs de sécurité à ouverture rapide. Un de nos agents a perdu un procès en raison de la formulation de la procédure d'inspection. De plus, la loi de notre État rend obligatoire l'utilisation de ces dispositifs.
Justification ou besoin	Conformément aux instructions du NAS-B, la diapositive PowerPoint indique de suivre les politiques et les procédures des agences lors du test du dispositif de rupture.
Demande d’action	Supprimez de la page 10 du document « Inspection des freins hydrauliques et des remorques » la phrase (Ne pas activer le dispositif de freinage d'urgence pendant l'inspection). Conservez la phrase (Dans certains cas, le dispositif de freinage d'urgence de ces remorques est une fonction à usage unique). Ajoutez ensuite : « Suivez les politiques et les procédures de votre organisme si vous activez le dispositif de freinage d'urgence pendant votre inspection. »
Mesures prises par le comité	Whether to pull the breakaway device, or not, on an electric brake vehicle has been a topic of debate for many years. Committee members have been in agreement that no one has seen the single use device but have been hesitant to remove the guidance from the hydraulic brake bulletin. Whether to pull the device has then been left up to the individual inspector or jurisdiction. This has led to a lack of uniformity in the enforcement of the breakaway brakes on these trailers. Committee members agreed that there needs to be a uniform standard for all jurisdictions to follow. The hydraulic brake bulletin tells inspectors not to pull the breakaway while the NAS Part B course leaves it up to the jurisdiction. The question was asked as to whether or not data could be obtained on how many violations were written for a defective breakaway system. This data is not available since 393.43(d) will not be specific to electric brakes. A concern was voiced about the possibility of breaking parts when the pin is pulled. The one-time use devices have not been seen and the multi-use devices should be tested during pre-trip inspections. If the proper procedures are followed, there should not be a concern of breaking the device. One committee member stated he specifically asked a manufacturer about pulling the breakaway device because drivers had told him the manufacturers recommend not testing it. The manufacturer’s response was that they are designed to be tested so testing the device roadside is not a problem. The Committee agreed to amend the bulletin to conduct the breakaway device test. Committee members had further discussion that the proper procedure needs to be followed when conducting the test. The amendment included the proper procedure contained in the NAS Part B course, for testing electric breakaway brakes to be added into the Inspection Bulletin 2012-04.

Mesures prises par le comité

Whether to pull the breakaway device, or not, on an electric brake vehicle has been a topic of debate for many years. Committee members have been in agreement that no one has seen the single use device but have been hesitant to remove the guidance from the hydraulic brake bulletin. Whether to pull the device has then been left up to the individual inspector or jurisdiction. This has led to a lack of uniformity in the enforcement of the breakaway brakes on these trailers. Committee members agreed that there needs to be a uniform standard for all jurisdictions to follow. The hydraulic brake bulletin tells inspectors not to pull the breakaway while the NAS Part B course leaves it up to the jurisdiction. The question was asked as to whether or not data could be obtained on how many violations were written for a defective breakaway system. This data is not available since 393.43(d) will not be specific to electric brakes. A concern was voiced about the possibility of breaking parts when the pin is pulled. The one-time use devices have not been seen and the multi-use devices should be tested during pre-trip inspections. If the proper procedures are followed, there should not be a concern of breaking the device. One committee member stated he specifically asked a manufacturer about pulling the breakaway device because drivers had told him the manufacturers recommend not testing it.
