Guidance on Safe Use

First-aid measures

General information: As a general rule, in case of doubt or if symptoms persist, always call a doctor.

Never give anything by mouth to an unconscious person. If unconscious, place

in recovery position and seek medical advice.

First aide personnel: pay attention to self-protection!

Dust may be irritating to the respiratory tract and cause symptoms of bronchitis. Risk of serious damage to eyes. Repeated contact may cause skin sensitisation.

In case of inhalation: Remove victim to fresh air and keep at rest in a position comfortable and well-ventilated for breathing. In case of irritation of respiratory system or mucous membranes and/or indisposition and/or prolonged exposure, seek medical attention.

In case of skin contact: Remove all contaminated clothing immediately. Wash thoroughly with plenty of soap and water. If irritation develops, seek medical attention. Consult a doctor if skin irritation persists. Launder clothes before reuse.

In case of eye contact: Rinse immediately and as long as possible with plenty of water. Remove contact lenses if present and easy to do – continue rinsing. Eyelids should be held away from the eyeball to ensure thorough rinsing. Always seek medical advice.  

In case of ingestion: Rinse mouth thoroughly with water. In case of spontaneous vomiting be sure that vomitus can freely drain due of danger of suffocation. Give water repeatedly. If vomiting occurs, keep head lower than hips to help prevent aspiration. Do not induce vomiting/risk of damage to lungs exceeds poisoning risk. Give nothing by mouth in cases of unconsciousness or convulsion. Get medical attention immediately and show the container or label.

In case of body contact: Take off contaminated clothing and wash it before reuse.

Self-protection of the first-aiders: No action shall be taken involving any personal risk or without suitable training.

Notes to physician: Symptomatic treatment is advised.

Fire-fighting measures

Suitable extinguishing media: Waterspray, water mist, foam, dry chemical powder.

Extinguishing media which must not be used for safety reason: Waterjet.

Special hazards arising from the substance or mixture: Emits toxic fumes under fire conditions: hydrogen cyanide (HCN), nitrous gases (NOx)

Advice for fire-fighters: Wear full protective clothing. Wear self-contained breathing apparatus.

Other information: Do not allow run-off from the fire fighting to enter drains or water courses. Do not enter fire area without proper protection.

Accidental release measures

Personal precautions, protective equipment and emergency procedures: No action shall be taken involving any personal risk or without suitable training. Avoid dust formation. Evacuate surrounding areas. Keep unnecessary and unprotected personnel from entering. Provide adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Use personal protective clothing. Avoid inhalation of vapours/dust. Avoid contact with eyes, skin and clothing. Put on appropriate personal protective equipment.

Environmental precautions: Do not flush into public water courses. Discharge into the environment must be avoided.

Methods and material for containment and cleaning up Spills/Leaks: Collect as much as possible in a clean container for (preferable) reuse or disposal.

Handling and storage

Precautions for safe handling: As a general rule, do not eat, drink and smoke in work areas; wash hands after use; remove contaminated clothing and protective equipment before entering eating areas. In accordance with good industrial practice, industrial hygiene principles and relevant legal provisions, handle with care and avoid unnecessary personal contact. Closed containers should be opened in well-ventilated areas.

Although the substance is in a flask form and consequently dust levels will be low, it is recommended to take precautions to avoid breathing dust.

Handling requirement: Ensure good ventilation/local exhaust at the workplace. Handle and open container with care. Avoid creating dusty conditions. Keep away from ignition sources. Avoid inhalation, skin and eye contact. Avoid breathing dust. Wear appropriate personal protective equipment. Close containers immediately after use.

Conditions and materials to avoid: Direct sunlight, excessive light, moisture, oxidizing conditions, excessively high temperatures, sparks and open flame, dusting conditions.

Conditions for safe storage, including any incompatibilities: Keep container tightly closed in a dry, cool and well-ventilated place against strong oxidizers when not in use and during transport, prevent contamination with foreign materials. Keep chemical away from direct sunlight, heat, sparks, open flame and other ignition sources. Keep away from food and drink. Store in the original container securely closed. Protect from moisture and physical damage.

Exposure controls / personal protection

Appropriate engineering controls: Work in well ventilated areas. Local exhaust ventilation is generally required because it can control the emissions of the contaminant and its source, preventing dispersion of it into the general work area.

Precautionary and hygiene measures: Precautionary measures: Do not handle this chemical near heat, sparks or open flame. Prevent electrostatic discharge formation. Avoid accumulation of dust in enclosed space. Keep container closed when not in use. Avoid contact with eyes, skin and clothing. Do not breathe dust. Use with adequate ventilation/personal protection. Before using this substance as such or mixtures containing, read SDS.

Hygiene measures: Wash hands, the forearms and face thoroughly after handling this substance or mixtures containing substance, before eating, smoking and using the lavatory and at the end of the working period. Appropriate techniques should be used to remove potentially contaminated clothing. Wash contaminated clothing before reusing. Do not eat, drink or smoke while working. Keep away from foodstuffs, beverages and food. During synthesis,  formulation or application, follow good industrial hygiene practices. Emergency eye wash fountains and safety showers should be available in the immediate vicinity of any potential exposure.

Respiratory protection: In case of insufficient ventilation, wear suitable respiratory equipment, such as a NIOSH-certified (or equivalent) organic vapour/particulate respirator. In case of brief exposure or low pollution use respiratory filter device. In case of intensive or longer exposure use respiratory protective device that is independent of circulating air.

Hand protection: Wear suitable gloves with long cuffs. Gloves should be worn at all times when handling substance and/or mixtures containing the substance. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove’s outer surface) to avoid skin contact with this chemical. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The glove material has to be impermeable and resistant to the substance or/and mixtures containing the substance.

Eye protection: Wear eye/face protection, such as tightly fitting safety goggles (chemical goggles) and face shields.

Skin protection: Wear suitable protective clothing, closed footwear. The skin protection equipments should be cleaned thoroughly after each use.

Body protection: Impermeable protective work clothing, closed footwear.

Thermal hazards: No specific information.

Environmental exposure control: Do not allow the substance or mixtures containing the substance or contaminated containers to enter drains, sewers or water courses. Do not allow to directly enter the environment. Any potential releases to environment should be avoided.

Stability and reactivity

Chemical stability: Stable under ordinary conditions of use and storage.

Possibility of hazardous reactions: No specific information.

Conditions to avoid: No specific recommendations.
