Guidance on Safe Use

First-aid measures

General information:

In all cases of doubt, or when symptoms persist, seek medical advice. If victim is at risk of losing consciousness, position and transport on their side. Do not

allow victim to become chilled. Keep victim warm.

After inhalation: Move victim to fresh air, put at rest and loosen restrictive clothing. In case of irregular breathing or respiratory arrest provide artificial respiration. Seek medical attention.

In case of skin contact: Take off immediately all contaminated clothing. Remove residues with soap and water. In case of skin reactions, consult a physician.

After eye contact: Immediately flush eyes with plenty of flowing water for 10 to 15 minutes holding eyelids apart. Subsequently consult an ophthalmologist.

After swallowing: Rinse mouth immediately and drink plenty of water. Do not induce vomiting. Danger of aspiration. Seek medical attention.

Most important symptoms and effects, both acute and delayed

Burning eyes and skin. Irritation of nose, throat, lung. Cough, nausea, dizziness, unconsciousness. In case of prolonged exposure: Possible danger of damage to liver and kidneys.

Indication of any immediate medical attention and special treatment needed

Treat symptomatically. On irritation of the respiratory system use an aerosol dispenser and treat with 5 doses of dexamethasone aerosol (e.g. Auxiloson, Thomae) every 10 minutes until symptoms cease. In case of intense exposure check liver and renal function. Concentration > 600 ppm: Leads to severe irritation of the mucous membranes.

Fire-fighting measures

Suitable extinguishing media: Extinguishing powder, alcohol resistant foam, carbon dioxide, water fog

Extinguishing media which must not be used for safety reasons: Full water jet

Occupational exposure controls

All information for relevant exposure scenarios including operational conditions and risk management measures are listed in 'Annex I of the eSDS: worker exposure and risk assessment'.

With regard to dermal protective equipment:

In all cases, the protective gloves to be used should be chemically resistant gloves conform EN 374. Specific activity training is applicable for all “industrial setting” activities.  Within “professional settings” basic employee training is required.

The recommended glove materials for the manipulation of AMS as pure substance are either:

- Polyvinyl alcohol (PVA) with a breakthrough time of 360 min, the thickness of PVA gloves is not applicable.

- Fluororubber (Viton) with a breakthrough time of 480 min. Thickness typically of 0.30 mm.

- Other gloves may be used if the breakthrough time for AMS communicated by the glove manufacturer exceeds the time of the activity for which the glove is to be used.

- The glove manufacturer's instructions concerning penetrability and breakthrough time should be verified in all cases before use as this can differ between the different manufacturers.

Dependent on the activity, the most suitable glove is to be selected. Both referenced gloves are considered suitable both for splashing and immersion. The glove selection is to be made primarily based on the duration of the task. For activities of > 6hr/day the Viton gloves are to be used. In other cases, the PVA gloves can be taken into consideration.

When the activities regard the manipulation of mixtures of AMS, the preferred glove needs to be determined in function of the actual mixture. The registrant cannot provide exact details on these measures. The downstream users need to verify whether the type of glove that is uses is appropriate for the mixture of concern.

With regard to respiratory protective equipment:

Respiratory protection: The respiratory protection that is to be used, when described in the contributing work scenario, is a filter type A (= against vapours of organic substances) according to EN 14387 (Class 1 up to 0,1 Vol-%, Class 2 up to 0,5 Vol-%, Class 3 exceeding 1 Vol-%).

Eye protection: Tightly sealed goggles according to EN 166.

Body protection: Wear suitable protective clothing. Rubber coat and trousers. Safety shoes according to EN 345-347. In case of handling larger quantities: flame-retardant protective clothing, antistatic.

General protection and hygiene measures: Do not breathe vapours. Avoid contact with skin, eyes, and clothing. Immediately remove any contaminated clothing, shoes or stockings. Wash hands before breaks and after work. When using do not eat, drink or smoke. Have eye wash bottle or eye rinse ready at work place. Alternatives to the following personal protective measures can only be determined in agreement with a responsible safety expert.

Environmental exposure controls

All information for relevant exposure scenarios including operational conditions and risk management measures are listed in 'Annex II of the eSDS: Environmental Exposure and Risk Assessment and Annex III of the eSDS: Environmental Exposure Calculation Tool'. Waste air is to be released into the atmosphere only via suitable separators/filter.

Stability and reactivity

Reactivity

Highly flammable liquid and vapour. Vapours are heavier than air. Polymerization can occur under certain conditions. See section 10.3.

Chemical stability

Product is stable under normal storage conditions.

Possibility of hazardous reactions

Polymerisation in the presence of acids. Polymerization along with heat production. Heat development leads to selfignition. Due to the high vapour pressure, bursting danger to containers/vessels when temperature increases. Polymerisation occurs strongly exotherm and can lead to violent reactions. As polymerisation inhibitor 4-tert-Butylpyrocatechol is used (10 - 20 ppm).

Conditions to avoid

Pressure (danger of polymerization). Do not expose to temperatures exceeding 50°C/122°F.

Incompatible materials

Acids, peroxides, metal salts, organic metal compounds, oxidizing agents

Hazardous decomposition products

In case of fire may be liberated: Carbon monoxide and carbon dioxide.

Disposal considerations
