Frequently asked questions
This refresher is suited to people involved in confined space entry and gas detection who need to refresh safe working practices and maintain confidence in the role. That includes entrants, standby people, supervisors, permit receivers, permit issuers, and managers overseeing this work. It is particularly useful where confined space and gas detection tasks are performed regularly or where organisations want a more consistent approach to permits, monitoring, and communication.
Many clients, sites, and industry standards expect Confined Space and Gas Detection Refresher training to be completed regularly to help workers maintain competency in high-risk environments. While legislation does not prescribe a fixed refresher interval, PCBUs are expected to ensure workers remain capable of carrying out confined space work safely. Refresher training is commonly used to review gas detection, hazardous atmospheres, permit systems, and critical confined space controls.
Yes, learners should already hold one or more of the relevant unit standards before attending this refresher. Learners will only be refreshed against the unit standards they currently hold.
No, this refresher is not intended to replace initial confined space and gas detection training for someone new to this work. It is designed for learners who already hold the relevant unit standards and need to revisit confined space controls, atmospheric monitoring, and safe decision-making practices.
Yes. This refresher is completed online as a pre-recorded webinar through IMPAC’s LMS. Learners can complete the training at their own pace while revisiting confined space and gas detection requirements, controls, and safe work practices.
This refresher pre-recorded webinar takes approximately 4 hours to complete, depending on the learner’s pace. Delivered online through IMPAC’s LMS, learners can complete the training at a time that suits them.
Yes, this pre-recorded webinar refresher includes an assessment to confirm learners can still apply confined space entry and gas detection requirements safely.
No, this refresher does not award new NZQA unit standards. It is designed for learners who already hold the relevant confined space and gas detection unit standards and need to refresh their knowledge and practical capability.
IMPAC recommends that learners complete refresher training at least every two years to maintain their knowledge and competency. Some clients or industry requirements may require more frequent refreshers.
Learners who complete the refresher webinar and assessment will receive an updated IMPAC Certificate of Competency covering the confined space and gas detection unit standards they currently hold.
