How often must a worker holding a certificate of competency be given refresher training under a mine training scheme?

• A. Every 12 months
• B. Every 3 years
• C. At least once every 5 years
• D. Every 7 years

Answer: (C)

Regular refresher training keeps a worker’s certificate of competency current with evolving safety rules, procedures, and equipment in mining. Under a mine training scheme, this refresher must be completed at least once within every five-year cycle. This five-year cadence ensures workers are updated on changes while avoiding unnecessary repetition. Training more often would add cost without added safety benefit, while waiting longer than five years risks having outdated practices go unreviewed; a three-year interval would be stricter than required, and seven years would be too long to maintain currency.
