Boosting a Vehicle


This Safe Work Practice (SWP) will provide YG employees with a set of guidelines or “Do’s and Don’ts” that have been developed to mitigate hazards associated with this work task, as identified through your workplace hazard identification process. All YG employees performing this work task are required to be trained, knowledgeable and competent.

Guidelines: This practice is used when a primary vehicle battery has insufficient charge to start the vehicle. This is a stop-gap alternative used until the battery is recharged or replaced.



a)    The individual with the greatest amount of experience should direct the process.

b)    Wear High-Vis vests or other type of light and/or reflective clothing (if available) while performing this task in high traffic areas.

c)    Position the donor vehicle engine close to the receiver vehicle battery, out of direct traffic. Do not let the vehicles touch each other.

d)    Clean terminals of both batteries so the “+” and “-“marks can be clearly seen.

e)    Connect the red cable to the “+” posts of each vehicle battery.

f)     Connect the black cable to the “-“post of the good donor battery.

g)    Lastly, connect the other end of the black cable to an unpainted metal part of the vehicle engine. Note: if vehicle(s) are equipped with MRS radio, power supply to radio must be disconnected before boosting. See MRS Cheat sheet

h)   Start the donor vehicle engine (note that some newer vehicles advise to leave engine off due to internal computer sensing issues-consult owners manual).

i)     Start the receiver vehicle engine.

j)     Once the car is running, remove the cables in the reverse order.

k)    Allow receiver vehicle engine to run for at least 10 minutes in order to sufficiently recharge the battery.



a)    Do not attempt to auxiliary boost a frozen battery or from which all the electrolyte fluid  has evaporated

b)    Do not attempt an auxiliary boost if the donor voltage source is greater than 15 volts (eg. heavy equipment).

c)    Do not perform this task in the presence of flammable materials.
