AHU Inspections

The inspection of air handling units (supply & extract) and associated distribution ductwork is important to assess condition, compliance, hygienic status and system cleanliness. Each section of plant from fresh air inlet, frost coil, pre-filters, heater and chiller section, humidifiers and secondary filters through the distribution ducting to the terminal devices is surveyed.

Is Ventilation Plant & Ductwork Inspection required?

Yes:- The Workplace (Health, Safety & Welfare) Regulations 1992 came into force in 1996. These regulations were accompanied by an Approved Code of Practice and Guidance (L24) which has been updated and L24 (Second edition) was published in 2013 - Regulation 6 covers Ventilation:
