January 25, 2024
SUBJECT:
Version 2 drains in the ESS compartments will not deploy when required.
ISSUE:
The dissolving powder washer in the version 2 drains is not working correctly.
SUMMARY:
Inspect for version 2 drains and rework them to remove the washer and reinstall them. Mark the reworked drains with a green paint marker.
ITS60913
Chronology :
September 2023, a drain valve for the ESS assembly was released which had a washer added to the face of the “bobbin” (internal component which reacts to liquid exposure). This was added to inhibit nuisance activation of the drain valve during times of high humidity and temperature.
December 2023, testing was being performed on an ESS assembly to validate liquid level calculations vs physical testing prior to drain valve activation. This testing indicated a less than optimal activation time of some of the drain valves.
December 2023/January 2024 testing and analysis continued on the delayed activation experienced from the drain valve and was ultimately determined the washer added to inhibit nuisance activation was impeding the bobbin from full function within a reasonable timeframe.
This issue was reviewed by the Vehicle Safety Committee during a special meeting on January 25, 2024, where the need for a recall was concurred, culminating in this 573 filing.

Appendix A – NFIL Spec 532295 – High Voltage Safety Guidelines & Procedures for New Flyer Battery Bus
The following provides general guidelines in relation to safety and best practices when completing installation or servicing work on any New Flyer battery bus vehicle platform.
This document is not meant to supersede the actual released installation and assembly drawings and where conflicts arise, the released engineering drawings take precedence.
Introduction
The utmost concern, while working with High Voltage (HV) systems, is the safety of yourself, other personnel, and the potential of damage to property. To minimize these risks, it is crucial to be properly trained and always maintain a very alert, questioning, and disciplined attitude without fail. As soon as your guard is lowered, then the potential of an accident is probable that can hurt or kill yourself or someone else and possibly damage property.
What is High Voltage (HV)?
Any form of voltage that is greater than 50 volts if the person’s skin at the electrical contact points is not compromised and not wet.

Personnel Requirement
Only trained personnel shall supervise and perform High Voltage system testing, checkout, and troubleshooting. Two personnel (one called the Checker & the other called Monitor/Recorder) shall perform Checkout Procedures, together, to ensure safety of themselves, others nearby & for the protection of vehicle & property. Refresher training shall be provided to these personnel on a regular basis and when new systems are to be checked by them. The training of the personnel shall consist of:
HV & low voltage basics, intermediate & advanced electricity
HV & low voltage electrical systems of the vehicle
Shop safety practices & procedures
First aide including CPR & the use of the shop defibrillator
How to release a victim that can’t let go HV
Quickest method of shutting down HV
Firefighting and emergency procedures
HV & arc flash safety
Organized & tidy placement of equipment & tools allowing for
unrestricted movement
Operation of Hi-pot
To ensure effectiveness of training, exams of the trained material shall be required with a high passing mark of at least 80% and a retraining of the missed 20 % on a one-to-one basis.
Checker Function
(Caution: The Checker must not have any health conditions that can be exacerbated when startled and must not have any electronic implants.)
Directed by the Monitor/Recorder
Performs all preparations & checks
Wears PPE as specified by the Checkout Procedure
Performs all restorations
Vehicle Inspection
It is necessary that the vehicle to be checked out, first be visually inspected of all systems, workmanship and with special attention to ensuring there is no HV cable or equipment damage or chafing.

High Voltage Checkout Preparation
(1) The scope of the work must be accurately defined such as a Checkout Procedure that requires systematic steps with sign offs. Before a Checkout is performed, the Supervisor, Checker and Monitor/Recorder must conduct a briefing of what shall transpire, identify potential hazards, resist pressures of “is it done yet?”, anticipate problems and question possible events. If unexpected
electrical hazard or fault occurs, during any time of the Checkout, it must be immediately reported to the supervisor. After the Checkout is completed, the same group should review the results and processes and make proposed modifications to the procedures if required.
(2) Install Safety barricade with warning lights & signs indicating “Danger High Voltage” around the vehicle perimeter and ensure no personnel are within the fenced perimeter during the checkout procedure.
(3) It shall always be the goal to check the systems as much as possible with all HV power OFF and Locked Out/Tagged Out and proven as de-energized by voltage measurement using the DMM. The functionality of the DMM must be proved before and after the verification of no HV present. Then, if possible, the HV systems should be challenged by trying to energize them while checking that no
HV appears.
(4) When it is necessary to perform tests of HV systems with the power ON, then the Working Live procedure must be followed.
(5) The test personnel shall always rehearse the actions required in case of any possible accident scenarios.
(6) Before beginning the Checkout Procedure, the test personnel shall remove all their jewelry (including pierced ones), watches and any electrically conductive objects on them.
PPE Requirements
The PPE voltage class, Arc Flash and Arc Blast rating shall be compatible with the voltage and Arc Flash capability of the systems being tested. Appropriate leather glove protectors shall be worn over the HV rubber gloves.
PPE Care & Testing
Rubber insulated PPE shall be periodically cleaned and tested in accordance with 29 CFR 1910.137 and the appropriate ANSI/ASTM standards. HV gloves, sleeves and mats shall be tested every 6 months. PPE apparel shall be cleaned and maintained in accordance with the manufacturer’s instructions. A record of the PPE testing shall be maintained and available to the users.

PPE Inspection
Inspect PPE equipment, before use, for any degradation or damage and ensure that the HV gloves have been tested every 6 months. Also perform an air pressure test on the HV gloves before and after each use. If during PPE use a potential damaging incident occurred to the PPE, stop further testing and inspect the PPE. If at any time the PPE is defective, reject it, and obtain an accepted one.
PPE Storage
PPE apparel should be stored lying flat, undistorted, right-side out and not folded in protective containers. The HV mats can be rolled with an inside diameter greater than 2 inches.
Rubber HV gloves should be stored in cool, dark, dry, and free from damaging chemicals or vapors. The glove cuffs should face downwards, without folding, in the appropriate glove bag and hung vertically.
Insulated Tools
Insulated tools should be visually inspected for insulation damage before and after each session of use.
Lockout/Tagout Procedure
The Lockout/Tagout procedure should be followed that is specified in the respective checkout procedure. When removing the lock and tag:
(1) The locks and tags shall be removed by the installer of them or under her/his supervision.
(2) If the installer of the locks and tags is not available, then her/his supervisor:
(a) Ensures that the installer of the locks and tags in not in the facility
(b) Contacts the installer to inform her/him that the locks and tags will be removed
(c) Reminds the installer of the lock and tag removal when she/he resumes work
Stored Energy
Personnel must always remember the characteristics of stored energy devices such as capacitors and batteries and when energy is available from.
Working Live
To maximize safety, it is always important to perform the maximum amount of HV checkout in the de-energized state.
When it is necessary to work with HV equipment while energized or to verify whether HV is present, the utmost care and safety procedures must be utilized including:
(1) Wearing appropriate PPE with protector gloves over top of the HV rubber gloves
(2) Ensure all personnel, except the Checker and Monitor/Recorder, are clear of the vehicle
(3) Kneeling or standing on HV insulated mat

Energizing & De-energizing Procedure
It is critical that before any HV system is energized that a visual check be performed to ensure that all possible HV compartments are closed and there is no debris, tools or test equipment lying on HV terminations. If there is a certain sequence of energizing and de-energizing the HV system, then all personnel involved must be trained in this sequence. (CAUTION: Never try to connect or disconnect circuit components such as cables, fuses, connectors, etc. while there is current flowing in the circuit.)
Electrical Injuries
Electrical injuries should be immediately reported to the first aide personnel and the supervisor. Other than electrostatic shocks, even non-injurious electrical shocks should be reported to the supervisor. These should be immediately investigated and documented to determine the cause and prevent the occurrence in the future.
