Guidance on Safe Use

First-aid measures

SKIN  In case of skin irritation rinse affected areas with water and wash gently. Do not rub or scratch exposed skin.

EYES In case of eye contact flush abundantly with water; have eye bath available. Do not rub eyes.

NOSE AND THROAT:If these become irritated move to a dust free area, drink water and blow nose

Fire-fighting measures

Non combustible substance

Accidental release measures

Where abnormally high dust concentrations occur, provide workers with appropriate protective equipment

Restrict access to the area to a minimum number of workers required.

Restore the situation to normal as quickly as possible.

Prevent further dust dispersion for example by damping the materials.

METHODS FOR CLEANING UP

Pick up large pieces and use a vacuum cleaner fitted with high efficiency filter (HEPA)

If brushing is used, ensure that the area is wetted down first.

Do not use compressed air for clean-up.

Do not allow to be wind blown.

Do not flush spillage to drain and prevent from entering natural watercourses.

Handling and storage

Process should be designed to limit the amount of handling.

Whenever possible, handling should be carried out under controlled conditions (i.e., use dust exhaust system).

Using specially treated or packaged products will minimise dust release.

Regular good housekeeping will minimise secondary dust dispersal.

Store in original packaging in dry area whilst awaiting use

Always use sealed and visibly labelled containers.

Avoid damaging containers.

Reduce dust emission during unpacking.

Emptied containers, which may contain debris, should be cleaned before disposal or recycling.

Exposure controls / personal protection

Exposure controls

Check exposure limits currently applying in your country and comply with local regulations. (Hygiene standards and exposure limits may differ from country to country)

Review your RCF application(s) and assess situations with the potential for dust release.

Where practical, enclose dust sources and provide dust extraction at source.

Designate RCF work areas and restrict access to informed and trained workers.

Use operating procedures, which will limit dust production and exposure of workers.

Keep the workplace clean. Use a vacuum cleaner fitted with an HEPA filter; avoid using dry sweeping and compressed air for cleaning.

Using products specially tailored to your application(s) will help to control dust. Some products can be delivered ready for use to avoid further cutting or machining. Some could be treated or packaged to minimise or avoid dust release during handling.

Personal Protective Equipment

Wear gloves and work clothes, which are loose fitting at the neck and wrists.

Soiled clothes should be cleaned to remove excess fibres before being taken off (e.g. use vacuum cleaner, not compressed air).

Each worker should be provided with two lockers in an appropriate changing and washing area.  

Work clothes should be washed separately by the employer.  Work clothes should not be taken home.       

As necessary wear goggles or safety glass with side shield

For dust concentrations below the exposure limit value, respiratory protective equipment (RPE) is not required but may be used on a voluntary basis.

For short term operations where excursions are less than ten times the limit value use as a minimum FFP3 respirators/ half mask with P3 filters.

Information and training of workers should include:

Details on those applications involving RCF-containing products ;

The potential risk to health resulting from the exposure to fibrous dust ;

The requirements regarding smoking, eating and drinking at the workplace ;

The requirements for protective equipment and clothing.

The good working practices to limit dust release ;

The proper use of protective equipment.

Environmental control measures                     

Refer to local, national or European applicable environmental standards for release to air, water and soil.

Stability and reactivity

Stable , non reactive ,insoluble substance

DECOMPOSITION PRODUCTS              

Upon heating above 900°C for sustained periods, this amorphous material begins to transform to mixtures of crystalline phases.

Disposal considerations

RCF is categorised as a stable non-reactive hazardous waste, which can generally be disposed of at landfill, which has been licensed for this purpose. Please refer to the European list (Decision no 2000/532/CE as modified) to identify your appropriate waste number, and ensure national and or regional regulation are complied with. Taking into account any possible contamination during use, expert guidance should be sought.

Unless wetted, such a waste is normally dusty and so should be properly sealed in clearly labelled containers for disposal. At some authorised disposal sites, dusty waste may be treated differently in order to ensure they are dealt with promptly to avoid them being wind blown. Check for national and/or regional regulations, which may apply
