Chlorhexidine dihydrochloride

Guidance on Safe Use

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. Consult an ophthalmologist immediately if the symptoms persist.

Ingestion:

Rinse mouth. Immediately give large quantities of water to drink. Obtain medical attention.

Most important symptoms and effects, both acute and delayed:

Symptoms: Irritation of skin and mucous membranes

Hazards: irritant effects

Indication of any immediate medical attention and special treatment needed:

The initial focus is only on the local action, possibly characterized by a progressive tissue irritation. In the eye, irritating solids cause, depending on the intensity of exposure, irritation of the conjunctiva and, in exceptional cases, damage to the cornea. There is a danger of blindness if corneas are damaged! Superficial irritations and only infrequent damage with ulcerations develop on the skin.

Fire-fighting measures

Extinguishing media:

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

Unsuitable extinguishing media: Do not use a solid water stream as it may scatter and spread fire.

Special hazards arising from the substance or mixture:

Hazard-determining flue gases might develop in case of fire: Nitrogen oxides (NOx), hydrogen chloride, Carbon monoxide, Carbon dioxide (CO2), flammable smouldering gases

Advice for firefighters:

Contaminated extinguishing water must be treated at a suitable disposal plant in accordance with waste management laws. Ensure there are sufficient retaining facilities for water used to extinguish fire. In case of fire, remove the endangered containers and bring to a safe place, if this can be done safely. Fire residues should be disposed of in accordance with the regulations. Use water spray to cool unopened containers. Keep out unprotected persons. In the event of fire, wear self-contained breathing apparatus and full protective suit

Accidental release measures

Personal precautions, protective equipment and emergency procedures:

Keep unauthorized persons away. Avoid dust formation.

Environmental precautions:

Prevent substance from entering soil, natural bodies of water and sewer systems. If the product contaminates rivers and lakes or drains inform respective authorities.

Methods and material for containment and cleaning up:

Pick up mechanically. Collect in suitable containers. To absorb spilled substance an approved industrial vacuum cleaner is recommended. If necessary, the spilled substance should be moistened. Pack and label wastes like the pure substance. Do not detach label from the delivery containers prior to disposal. Dispose of absorbed material in accordance with the regulations.

Additional advice:

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

Handling and storage

Precautions for safe handling:

Wear personal protective equipment. When using do not eat, drink or smoke. Avoid formation of dust. Avoid residues of the product on the containers. No special measures are necessary if properly handled.

Conditions for safe storage, including any incompatibilities:

Advice on protection against fire and explosion: Caution - electrostatic charge may occur.

Keep away from sources of ignition - No smoking. Take precautionary measures against static discharges.

Avoid dust formation.

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.

Avoid exposure to light /sunlight

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.

Exposure controls / personal protection

Control parameters:

Other information: Contains no substances with occupational exposure limit values.

DNEL/DMEL values:

Remarks: No substance-related safety assessment is necessary / has been conducted for this product.

PNEC values:

Remarks: No substance-related safety assessment is necessary / has been conducted for this product.

Exposure controls:

Engineering measures: Ensure suitable suction/aeration at the work place and with operational machinery. Take precautionary measures against static discharges. Provide for installation of emergency shower and eye bath.

Personal protective equipment:

Respiratory protection: Wear dust mask in the presence of dust.

When handling for a short time: Respirator with P2 particle filter

In the event of prolonged exposure during handling: Wear a self contained respiratory apparatus

Note time limit for wearing respiratory protective equipment.

Hand protection:

Applies to handling for brief periods or of small amounts: Glove material: Nitrile, for example, Dermatril 740, Kächele-Cama Latex GmbH (KCL), Germany, Material thickness: 0.11 mm, Method: DIN EN 374

Applies to handling for longer periods or of large amounts: 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. The information is based on our own tests, references from the literature and information from glove manufacturers, or derived by analogy with similar materials.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:

Safety glasses with side-shields conforming to EN166 or, when handling larger quantities, basket-shaped glasses

Skin and body protection:

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

Protective measures:

Handle in accordance with good industrial hygiene and safety practice. Avoid contact with skin, eyes and clothing. If there is the possibility of skin/eye contact, the indicated hand/eye/body protection should be used.
