Guidance on Safe Use

First-aid measures

INHALATION:

Get medical attention immediately.Move exposed person to fresh air.If it is suspected that fumes are still present, the rescuer should wear an appropriate mask or self-contained breathing apparatus.Keep person warm and at rest.If not breathing, if breathing is irregular or if respiratory arrest occurs, provide artificial respiration or oxygen by trained personnel.It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation.If unconscious, place in recovery position and get medical attention immediately.Maintain an open airway.Loosen tight clothing such as a collar, tie, belt or waistband.In case of inhalation of decomposition products in a fire, symptoms may be delayed.The exposed person may need to be kept under medical surveillance for 48 hours.In the event of any complaints or symptoms, avoid further exposure.

INGESTION:

Get medical attention immediately.Wash out mouth with water.Move exposed person to fresh air.Keep person warm and at rest.If material has been swallowed and the exposed person is conscious, give small quantities of water to drink.Stop if the exposed person feels sick as vomiting may be dangerous.Do not induce vomiting unless directed to do so by medical personnel.If vomiting occurs, the head should be kept low so that vomit does not enter the lungs.Never give anything by mouth to an unconscious person.If unconscious, place in recovery position and get medical attention immediately.Maintain an open airway.Loosen tight clothing such as a collar, tie, belt or waistband.

SKIN CONTACT:

Get medical attention immediately. Remove contaminated clothing and shoes. Wash the skin immediately with plenty of soap and water; cleaning immediately with polyethyleneglycol 400 and washing subsequently with plenty of soap and water would be more effective. Wash skin immediately with plenty of soap and water even when contact with the product is suspected. Wash clothing before reuse. Clean shoes thoroughly before reuse.

EYE CONTACT:

Get medical attention immediately.Immediately flush eyes with plenty of water, occasionally lifting the upper and lower eyelids. Check for and remove any contact lenses. Continue to rinse for at least 10 minutes. Chemical burns must be treated promptly by a physician.

Stability and reactivity

Stability : Hazardous polymerization may occur under certain conditions of storage or use.

Possibility of hazardous reactions: Hazardous reactions or instability may occur under certain conditions of storage or use.

Conditions to avoid: Reactive with water, alcohols, acids, alkalis and amines. With water (in a closed container), pressure will increase and create a risk of bursting. Do not pressurise, cut, weld, braze, solder, drill, grind or expose containers to heat or sources of ignition.

Hazardous decomposition products: Under normal conditions of storage and use, hazardous decomposition products should not be produced.

Disposal considerations

Methods of disposal : Examine possibilities for re-utilisation. Product residues and uncleaned empty containers should be packaged, sealed, labelled, and disposed of or recycled according to relevant national and local regulations. Where large quantities are concerned, consult the supplier. When uncleaned empty containers are passed on, the recipient must be warned of any possible hazard that may be caused by residues. For disposal within the EC, the appropriate code according to the European Waste List (EWL) should be used. It is among the tasks of the polluter to assign the waste to waste codes specific to industrial sectors and processes according to the European Waste List (EWL).

Hazardous waste : The classification of the product may meet the criteria for a hazardous waste.
