Legal compliance regarding IAQ
The quality of IAQ is regulated in some areas such as Co2 and carbon monoxide, Ozone and formaldehyde
Occupational exposure to working chemicals and gases is strictly governed and regulated through legislation and guidance such as EH40 published by HSE.
However many substances found at the disaster scene are also regulated although not present in EH40 and indeed may not even have permissible exposure levels on which to base assessment.
Water damaged or flooded buildings which require any form of work as described by HSE, must follow the statutory legislation which includes Construction Design Management (CDM) 2015
In this legal requirement a COSHH assessment (Control of Substances Hazardous to Health) must be undertaken and quite apart of any chemical or products used in the work process the air and surfaces must be assessed for regulated substances.
Typically bio amplification will occur with 48 hours of water damage and this includes bacteria, virus and mould and may even include chemical off gassing from wet materials.
COSHH assessments in a water damage building must include the hazards listed by HSE and these include, skin and respiratory sensitisers, asthmagens etc all of which must be expected to be present in water damage and mould .
We show you how to comply with the law in a cost effective manner which is both compliant and will actually save money.
