First-aid measures

Description of first aid measures

Pay attention to self-protection.

Remove victims from hazardous area. Immediately remove soiled or soaked clothing and remove it to a safe distance. Keep victim warm, in a stabilized position and covered.

Do not leave victims unattended.

If the casualty is unconscious: Place the victim in the recovery position.

Inhalation

Potential for exposure by inhalation if dusts or smoke are generated.

Move victims into fresh air.

With labored breathing: Provide with oxygen. Consult a doctor.

If the casualty is not breathing: Perform mouth-to-mouth resuscitation, notify emergency physician immediately.

Skin contact

Wash off affected area immediately with plenty of water for at least 15 minutes.

If symptoms persist, consult a physician for treatment.

Eye contact

With eye held open, thoroughly rinse immediately with plenty of water for at least 10 minutes.

Inform emergency physician immediately. (key term: caustic eye burn)

Ingestion

Rinse mouth.

Immediately give large quantities of water to drink.

Inform emergency physician immediately.

Most important symptoms and effects, both acute and delayed

Symptoms

Causes burns.

Hazards

Strongly irritating to corrosive.4.3.       Indication of any immediate medical attention and special treatment needed

The initial focus is only on the local action, characterized by quickly progressing deep tissue damage.

Coughing is a symptom of respiratory tract after inhalation of dusts or smoke from caustic solids.

In the eye, caustic dusts or smoke cause, depending on the intensity of exposure, severe irritation, destruction, and ablation of the epithelium of the conjunctiva and cornea, corneal clouding, edema and ulcerations.

Danger! Possible loss of eyesight!

Superficial irritations and damage up to ulcerations and scarring develop on the skin.

Fire-fighting measures

xtinguishing media

Suitable extinguishing media:       Water spray, foam, CO2, dry powder.

Unsuitable extinguishing media:       high volume water jet

Special hazards arising from the substance or mixture

In case of fire cool endangered containers with water.

Hazard-determining flue gases might develop in case of fire:

Carbon oxides

organic products of decomposition

nitrogen oxides (NOx)

Advice for firefighters

Contaminated extinguishing water must be treated at a suitable disposal plant in accordance with waste management laws.

Water used to extinguish fire should not enter drainage systems, soil or stretches of water.

In case of fire, remove the endangered containers and bring to a safe place, if this can be done safely.

Use water spray to cool unopened containers.

Fire residues should be disposed of in accordance with the regulations.

Pay attention to self-protection.

Keep out unprotected persons.

In case of fire: full protective suit and wear a self contained respiratory apparatus

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Keep unauthorized persons away.

Avoid contact with the skin and the eyes.

Avoid dust formation.

Environmental precautions

Observe regulations on prevention of water pollution (check, dam up, cover up).

Do not allow entrance in sewage water, soil, stretches of water, drainage systems, surface water.

If the product contaminates rivers and lakes or drains inform respective authorities.

Methods and material for containment and cleaning up

Pick up mechanically and collect in a suitable container. Avoid formation of dust.

To absorb spilled substance an approved industrial vacuum cleaner is recommended. If necessary, the spilled substance should be moistened.

Clean contaminated surface thoroughly.

Pack and label wastes like the pure substance. Do not detach label from the delivery containers prior to disposal.

Disposal according to local authority regulations..

Handling and storage

Precautions for safe handling

Decant and handle product in separate areas only, e.g. use glove boxes, cabinets with differential pressure switch etc.

Ensure that apparatus and pipelines are free from leaks. Do not ventilate into the open.

Dedicated loading/unloading stations required.

Conditions for safe storage, including any incompatibilities

Advice on protection against fire and explosion

Normal measures for preventive fire protection.

Ensure there are sufficient retaining facilities for water used to extinguish fire.

Storage

Store in the original receptacle, keeping this tightly sealed, under cool and dry conditions.

Further information

Protect from sunlight, warmth and heat.

In order to ensure due transportation, make certain that stacks are of the correct height, containers are securely fastened so as not to fall off, and labelled according to the regulations.

In the event of internal transportation, already-opened containers are to be kept closed in order to avoid spillage.

Exposure controls / personal protection

Exposure controls

Engineering measures

Decant and handle product in separate areas only, e.g. use glove boxes, cabinets with differential pressure switch etc.

Do not lead exhaust air back to workplace areas unfiltered.

Exhaust filter or scrubber.

exhaust air filter (HEPA-filter)

Do not add wastewater to a biological wastewater treatment plant

In case of dissolved solids:

Minimization of emissions by means of suitable technical measures such as flanges and valves with low leakage rates, recirculation of vapours.

Ensure that dust-handling systems (such as exhaust ducts, dust collectors, vessels, and processing equipment) are designed in a manner to prevent the escape of dust into the work area (i.e., there is no leakage from the equipment).

All precautionary measures indicated have to be observed.

Exposure controls

The substance must be handled under strictly controlled conditions in accordance with Article 17/18 of the REACH regulation.

Personal protective equipment

Respiratory protection

Accidental release measures

use respiratory equipment with suitable filter (filter type P3) or wear a self contained respiratory apparatus

Note time limit for wearing respiratory protective equipment.

Hand protection

Glove material       Nitrile, for example, Dermatril 740, Kächele-Cama Latex GmbH (KCL), Germany

Material thickness       0,11 mm

Method              DIN EN 374

Accidental release measures

Glove material       Nitrile/Chloroprene, for example, Nitopren 717, Kächele-Cama Latex GmbH (KCL), Germany

Material thickness       0,65 mm

Method              DIN EN 374

Selection of protective gloves to meet the requirements of specific workplaces.

Suitability for specific workplaces should be clarified with protective glove manufacturers.

Remember that the useful time per day of a chemical protection glove may be much shorter than the permeation time determined according to EN 374 due to the many different influential factors involved (e.g. temperature).

Eye protection

close-fitting protective goggles (e.g. closed goggles)

Skin and body protection

Select materials and equipment for physical protection depending on the concentration and volume of hazardous substances and the workplace involved.

Hygiene measures

Remove and wash contaminated clothing before re-use.

Do not eat, drink, smoke, or sniff while at work. Wash your hands and/or face before breaks and before termination of work.

Preventive skin protection is recommended.

Written approval necessary in case of non-routine jobs, e.g. maintenance activities.

Regular safety training is a must.

The personal protective equipment used must meet the requirements of Regulation (EU) 2016/425 and amendments (CE certification).

It should be defined in the work place in the form of a risk analysis according to Regulation (EU) 2016/425 and amendments.

Environmental exposure controls

In some cases, exhaust air scrubbers, filters or technical changes to the processing plant will be required in order to decrease emissions to acceptable values.
