Health and safety

Lafarge Plasterboard products are marketedfor use in the drylining and decoration ofdomestic, commercial and retail buildings.Detailed instructions for the use of each product are given in this manual.

In addition Lafarge COSHH Data Sheets areavailable for all Lafarge products. Contactour Technical Enquiryline on 01275 377789.

The main health and safety issues createdby the use of Lafarge Plasterboard productsrelate to working habits and conditions andthe constituents used in the products. It isimportant that Lafarge Plasterboardproducts are used only in the manner forwhich they are intended and in accordancewith Lafarge Plasterboard’s instructions.

Safe working habits and conditions willensure that occupational exposure isminimised. To reduce airborne dust, openbags and mix products with water in wellventilated conditions; avoid contact of thedry products with eyes and skin; and alwayswash exposed skin after use. In the event ofcontact with eyes, irrigate immediately withplenty of water.

Cutting plasterboard with power tools andsanding generate dust, so should be kept toa minimum. Ideally all operations whichproduce dust should be carried out in wellventilated conditions; where possible a dustmask selected in accordance with EN 149should be worn.

The general approach to control ofoccupational exposure to airborne dust isoutlined in Health and Safety ExecutiveGuidance Note EA44.

The Health and Safety Executive GuidanceNote EH40/94 gives information aboutairborne concentration of substances in theworkplace for which constant daily exposurewill not cause harmful effects, known asOccupational Exposure Standards (OES). TheHealth and Safety Executive reviews OES’sannually in the light of new medicalevidence. The following tables show theOES values relevant to constituents ofLafarge Plasterboards products, taken fromEH40/94.

Good working practice on-site will help toeliminate other potential hazards. Heavyproducts should only be lifted in the correctway using mechanical handling equipmentwhere necessary. Metal components shouldbe cut and handled carefully to avoid cutsand abrasions and Lafarge recommends thewearing of gloves.

Plasterboard is a lining material and will notsupport body weight and adequate supportshould be provided for installers wherenecessary.

When using liquid products take care toavoid contact with eyes. Should thishappen, irrigate immediately with plenty ofclean water and seek medical advice.

Further information and advice on exposurelimits, codes of practice and regulations isreadily available from:HSE Library and Information Service,2 Rose Court, Southwark Bridge, London SE1 9HSTel: 020 7717 6000.

H E A L T H A N D S A F E T YSUSTAINABILITY


Recycling Gypsum Waste

The gypsum industry is committed tosustainability.

Gypsum products could be counted amongthe very few construction materials where“closed loop” recycling is possible, i.e.where the waste is used to make the sameproduct again and not merely recovered foruse in other “downcycling” applications asis the case with some other constructionmaterials, e.g. waste concrete and bricksused for aggregates in road construction.

The objective to recycle gypsum is not asstraightforward as the decision facing otherconstruction products. There are technicalobstacles that limit the proportion of wasteto raw gypsum that can be used in themanufacturing process. There is also anenvironmental penalty to pay as recyclinggypsum waste is more energy intensive thanusing raw gypsum, because of the need tocollect and transport the material, sort andpurify it and remove the moisture content,which is the most energy intensive part ofthe manufacturing process. Hand-in-handwith these considerations are the economicconsequences. Gypsum is a natural materialthat is used in construction due to itsthermal, acoustic and fire resistance, if itbecomes too expensive builders will beforced to use less environmentally friendlyalternatives.

Recycling of manufacturingscrap

While small quantities of raw gypsum scrapare left from the manufacturing process andcan be re-used without treatment, themajority of scrap is plasterboard off-cuts.This material includes paper which must beremoved before re-use. Because of this, theuse of such gypsum requires greater energythan using raw gypsum.

Recycling of construction &demolition (C&D) gypsum waste

Some construction waste is recovered andre-used, but this is energy intensive tocollect and treat. The gypsum industryworldwide is investigating the re-use ofconstruction gypsum waste as an objective.At present the economics of this activity aremarginal. However, it is expected to becomemore common as landfill restrictions make itcomparatively more attractive.

Demolition waste is a bigger problem withadditional contamination to remove (paper,paint, screws, wood, etc.). Over the next20-30 years the economics for demolitionwaste is expected to change as thequantities begin to increase substantially,due to the strong increase in the use ofplasterboard in construction which began inEurope in the 1960s and 1970s. Renovationand demolition work will see increasingvolumes of gypsum waste. The increasing

use of dismantling or deconstructiontechniques will increasingly make possibledemolition collection and recycling.

Successful and economic site waste recoveryis a partnership. Site managers need tomanage and segregate waste sufficientlywell to make it viable. Construction workersneed to be educated to think sustainably.Clients need to design the necessary cultureinto their construction projects at an earlystage. There is guidance available. For theUK see the DTI Site Waste Managementand Plans - Guidance for ConstructionContractors and Clients. It can bedownloaded at:http://www.dti.gov.uk/construction/sustain/site_waste_management.pdf

Other opportunities for gypsumwaste

Pure gypsum has traditionally been used asoil improver. The use of gypsum waste as asoil conditioner is strictly regulated and thequantities that can be used are limited.

Gypsum Waste Disposal (Englandand Wales)

The following is a statement from theGypsum Products Development Association

UK Regulations Governing WasteDisposal

The Waste (Duty of care) Regulationsimpose a legal duty of care upon anyonewho produces or imports, keeps or stores,transports, treats, recycles or disposes ofwaste. As of 16th July 2004, changesarising to the Landfill (E&W) (amendment)Regulations 2004 (SI2004:1375) havebanned the disposal of non-hazardous andhazardous waste materials together in thesame landfill and given further guidance onthe disposal of certain non-hazardouswaste.

Is gypsum waste hazardous?

No. It should be stated very clearly thatgypsum wastes, including plaster,plasterboard and gypsum products, areclassified as non-hazardous.

Environment Agency RegulatoryNote 11

RGN 11 gives guidance on best practice forthe disposal of wastes with high sulphate orgypsum contents. RGN 15 advising disposalin separate non-hazardous cells where nobiodegradable waste is present at landfillsite, because of the risk of release ofhydrogen sulphide gas, came into force inJuly 2005.

It is unfortunate that the EnvironmentAgency also includes in RGN 15 advice noteother products to be disposed in separatecells, namely ‘stable non-reactive hazardous

wastes’ and ‘asbestos wastes’. But it shouldbe made clear again that gypsum is notclassified with those wastes and is non-hazardous.

Further guidance

Gypsum wastes can continue to bedisposed of with current guidance and atsites with the appropriate wastemanagement license
