According to WorkSafe BC, the employer is responsible for establishing the lockout system to be implemented within the worksite. Lockout policies and procedures for lockout must be written.

The employer must make sure that each worker required to lock out machinery or equipment has access to enough personal locks to perform the required lockout procedure.

Each worker’s lock should be opened only by a key that is in the worker’s possession and by a key under the control of the supervisor or manager in charge. Combination locks must not be used for lockout.
