Hi, all.

G2OO gives a vague requirement that discharge should be away from air inlets/windows etc.

Does anyone know if there's anything more specific? Does it depend on contaminant?

Grateful for anything.

Which is G200? The HSE website gives this document when G200 is searched for https://www.hse.gov.uk/pubns/guidance/coshh-technical-basis.pdf

You haven't given enough information to answer the question. What are you discharging? A gas/vapour, dust/powder?

What is the hazard? Presumably not toxic, if being released to atmosphere. 

What about the other inlet? Is it a static inlet or a fan inlet to another part of the building.

What is the relative position of the discharge and other inlet duct? Are they level? Is the discharge higher than the inlet or vice versa??

If this were a flammable/explosive dust - the hazardous zone to an outside location would likely be circa 1m. But if you are controlling for CoSHH/occupational health reasons then the exposure limit, if listed in EH40, is very likely to be much less than an explosive dust concentration. Often by a magnitude of 100

Thanks, Ian.

It's actually a domestic situation: mine.

Communal drying machine duct discharges to roof right next to (literally) vent stack. My bathroom's being contaminated with dust/fluff. Duct recently found to contain asbestos - allegedly never had an LEV check. 1970 property.

Fraught discussions with Freeholder trying to get their co-operation. Was hoping for an 'at least' clause somewhere.

May not be ethical use of this forum. Soz.

Appreciate your time.

Sorry, yes. G200 is COSHH Essentials pub. HSGs and INDGs not much more helpful

Think your properties age means its construction pre-dates HASAW

You could try the Building Regulations but unless it has undergone a refurbishment making more recent rules applicable you would need to find the correct version for when the building was designed.

Approved Document F "Ventilation" may give something to discuss

Hi safetyamateur - nothing in the Forum rules says that someone cannot post about a concern about their own home, so no ethical concerns in my book.

However, would need more information about the positional relationship between where the vent from the communal laundry area is discharging and your bathroom ventilation arrangements.

That the duct for the LEV has been found to contain Asbestos Containing Materials may or may not be an issue depending on the type and condition of the ACM. Some fluff getting into your bathroom is probably more a nuisance than a health risk, but what is more concerning is the potential for ingress of asbestos fibres that you could not detect by sight.

Absolutely, Peter.

The main problem is that freeholder won't investigate and has, in fact, has told me to investigate. Tricky situation. I'm looking at EHO/property management/lease law too.

Thanks

Consider contacting your Local Council Environmental Health Dept. What you are describing may be a statutory nuisance and action can be taken against the company. The fluff could be cotton or similar material which can produce a serious risk to your health.( Look up byssinosis)
