Guidance on Safe Use

Handling and storage

HANDLING

Workplace:

Provision of good ventilation in the working area.

The floor must be solvent resistant.

Washing facility at the workplace required.

Eye bath required. These locations must be signposted clearly.

Equipment:

Use closed apparatus if possible.

If release of the substance cannot be prevented, then it should be suctioned off at the point of exit.

Consider emission limit values, a purification of waste gases if necessary.

Label containers and pipelines clearly.

Advice on safer handling:

Take care to maintain clean working place.

The substance must not be present at workplaces in quantities above that required for work to be progressed.

Do not leave container open.

Use leak-proof equipment with exhaust for refilling or transfer.

Do not transport with/using compressed air.

Avoid splashing.

Fill only into labelled container.

Use solvent resistant utensils.

Use an appropriate exterior vessel when transporting in fragile containers.

Cleaning and maintenance:

Use protective equipment while cleaning if necessary.

Only conduct maintenance and other work on or in the vessel or closed spaces after obtaining written permission.

STORAGE

Storage:

Do not use any food containers - risk of mistake.

Containers have to be labelled clearly and permanently.

Store in the original container as much as possible.

Use breakable containers only up to 5 litres content.

Keep container tightly closed.

Recommended storage at room temperature.

Keep container in a well-ventilated place.

Store apart from sources if ignition and heat.

Store smaller vessels in cabinets with collecting tubs.

Protect from exposure to light.

Protect from air/oxygen.

Protect from moisture.

Storage is not permissible in hallways, thoroughfare, stairways, public hallways and corridors, on the roof, in attics, and in workrooms.

Conditions of collocated storage:

Storage class 3 (Flammable liquid substances)

Only substances of the same storage class should be stored together.

Collocated storage with the following substances is prohibited:

- Pharmaceuticals, foods, and animal feeds including additives.

- Infectious, radioactive und explosive substances.

- Gases.

- Other explosive substances of storage class 4.1A.

- Flammable solid substances or desensitized substances of storage class 4.1B.

- Pyrophoric substances.

- Substances liberating flammable gases in contact with water.

- Strongly oxidizing substances of storage class 5.1A.

- Ammonium nitrate and preparations containing ammonium nitrate.

- Organic peroxides and self reactive substances.

- Non combustible acutely toxic substances of storage class 6.1B.

Under certain conditions the collocated storage with the following sub-stances is permitted:

- Oxidizing substances of storage class 5.1B.

- Noncombustible toxic or chronically acting substances of storage class 6.1D.

- Combustible solids of storage class 11.

The substance should not be stored with substances with which hazardous chemical reactions are possible

Exposure controls / personal protection

PERSONAL PROTECTION

Body protection:

Depending on the risk, wear a tight protective clothing or a suitable chemical protection suit.

Wear flameproof, antistatic protective clothing.

The protection clothing should be solvent resistant.

Respiratory protection:

In an emergency (e.g.: unintentional release of the substance) respiratory protection must be worn. Consider the maximum period for wear.

At present time there is no available information about suitable filter respirator.

A self-contained breathing apparatus can be used in any case.

Eye protection:

Sufficient eye protection must be worn.

Wear glasses with side protection.

Hand protection:

Use protective gloves. The glove material must be sufficiently impermeable and resistant to the substance. Check the tightness before wear. Gloves should be well cleaned before being removed, then stored in a well ventilated location. Pay attention to skin care.

Skin protection cremes do not protect sufficiently against the substance.

Textile or leather gloves are completely unsuitable.

The following materials are suitable for protective gloves (Permeation time >= 8 hours):

Butyl rubber - Butyl (0,5 mm)

Following materials are unsuitable for protective gloves because of degradation, severe swelling or low permeation time:

Natural rubber/Natural latex - NR

Polychloroprene - CR

Nitrile rubber/Nitrile latex - NBR

Fluoro carbon rubber - FKM

Polyvinyl chloride - PVC

The times listed are suggested by measurements taken at 22 °C and constant contact. Temperatures raised by warmed substances, body heat, etc. and a weakening of the effective layer thickness caused by expansion can lead to a significantly shorter breakthrough time. In case of doubt contact the gloves' manufacturer. A 1.5-times increase / decrease in the layer thickness doubles / halves the breakthrough time. This data only applies to the pure substance. Transferred to mixtures of substances, these figures should only be taken as an aid to orientation.

Occupational hygiene:

Take heed of usual occupational hygiene measures when handling chemical substances, espacially wash the skin with soap and water before breaks and at the end of work and apply fatty skin-care products after washing.

Avoid contact with skin. In case of contact wash skin.

Avoid contact with eyes. In case of contact rinse the affected eye(s).

Avoid inhalation of vapour or mist.

Avoid contact with clothing. Contaminated clothes must be exchanged and cleaned carefully.

Increased risk of combustion from wicking.
