Hydroxylamine

Guidance on Safe Use

First-aid measures

General advice:

Immediately remove contaminated clothing. First aid personnel should pay attention to their own safety.

If inhaled:

Keep patient calm, remove to fresh air, seek medical attention. After inhalation of decomposition products, remove the affected person to a source of fresh air and keep calm. Provide medical aid. Inhale corticosteroid dose aerosol.

On skin contact:

Wash thoroughly with soap and water.

On contact with eyes:

Immediately wash affected eyes for at least 15 minutes under running water with eyelids held open, consult an eye specialist.

On ingestion:

Rinse mouth immediately and then drink plenty of water, seek medical attention.

Most important symptoms and effects, both acute and delayed: See classification & Labelling;

Hazards: Risk of respiratory disorders

Indication of any immediate medical attention and special treatment needed; Note to physician

Treatment: Treat according to symptoms (decontamination, vital functions), treat with toluonium chloride to reverse methaemoglobinanaemia.

Fire-fighting measures

Suitable extinguishing media:

water

Specific hazards:

ammonia, nitrous gases; the substances/groups of substances mentioned can be released if the product is involved in a fire.

Special protective equipment: Wear a self-contained breathing apparatus.

Further information: Keep containers cool by spraying with water if exposed to fire. Collect contaminated extinguishing water separately, do not allow to reach sewage or effluent systems.

Accidental release measures

Personal precautions: Avoid contact with the skin, eyes and clothing. Avoid inhalation. Use breathing apparatus if exposed to vapours/dust/aerosol. Use personal protective clothing.

Environmental precautions: Do not discharge into drains/surface waters/groundwater.

Methods for cleaning up or taking up: For small amounts: Dilute with plenty of water. Oxidize with sodium hypochlorite or hydrogen peroxide. The indicated conversion should take place only in small portions because of gas formation.

For large amounts: Pump off product. Place into suitable container for disposal. Dispose of absorbed material in accordance with regulations.

Use of combustible materials (e.g. paper towels) to absorb the liquid can result in the heat of decomposition evaporating the liquid and causing the absorbent to self-ignite. Materials used to absorb the liquid in the product must be kept wet until decomposition is complete.

Handling and storage

Precautions for safe handling: Avoid contact with the skin, eyes and clothing. Processing machines must be fitted with local exhaust ventilation. Breathing must be protected when large quantities are decanted without local exhaust ventilation. Pressure relief device necessary. Containers under pressure should be opened with care to release pressure. Once container is opened, content should be usedup as soon as possible. Protect from direct sunlight. Transport and handling of IBCs/drums/containers containing crystallized product is safe under normal transport and handling procedures as long as no liquid has been removed. Ensure that there is no crystallized product in the container before use. Product may only be removed if the thermolabel is white or if the temperature measured by alternative methods is above 15 °C (59 °F). Solidified product can be dissolved in the container by gently applying indirect heat (no open flames, no contact heat). The temperatures which must be avoided are to be considered.

Protection against fire and explosion: Store in a cool place. If heated the drums can burst due to pressure build-up.

Conditions for safe storage, including any incompatibilities

Segregate from nitrites and alkaline substances. Segregate from lyes. Segregate from oxidants. Segregate from ammonium salts. Segregate from metals.

Further information on storage conditions: Danger of bursting when sealed gastight. Keep only in the original container at temperature not exceeding 50 °C. Protect from direct sunlight. Avoid deposition of dust.

Storage stability: Storage duration: 12 Months; It is recommended to keep a safe distance of +7 °C above the crystallization range.

Protect from temperatures above: 50 °C

Exposure controls / personal protection

Personal protective equipment

Respiratory protection: Suitable respiratory protection for lower concentrations or short-term effect: Gas filter EN 141 Type B for gases/vapours of inorganic compounds. Suitable respiratory protection for higher concentrations or long-term effect: Self-contained breathing apparatus.

Hand protection: Chemical resistant protective gloves (EN 374); Suitable materials also with prolonged, direct contact (Recommended:  Protective index 6, corresponding > 480 minutes of permeation time  according to EN 374):

polyvinylchloride (PVC) - 0.7 mm coating thickness

nitrile rubber (NBR) - 0.4 mm coating thickness

butyl rubber (butyl) - 0.7 mm coating thickness

Supplementary note: The specifications are based on own tests, literature data and information of glove manufacturers or are derived from similar substances by analogy. Due to many conditions (e.g. temperature) it must be considered, that the practical usage of a chemical-protective glove in practice may be much shorter than the permeation time determined in accordance with EN 374.

Manufacturer's directions for use should be observed because of great diversity of types.

Eye protection: Tightly fitting safety goggles (splash goggles) (EN 166)

Body protection: protective overalls (according to DIN-EN 465) with hood (Neopren-coated)

General safety and hygiene measures: Avoid inhalation of vapour. Avoid contact with the skin, eyes and clothing. Handle in accordance with good industrial hygiene and safety practice. At the end of the shift the skin should be cleaned and skin-care agents applied. Take off immediately all contaminated clothing. Store work clothing separately.

Stability and reactivity

Conditions to avoid: >= 52 weight %

Avoid concentrations above the mentioned value. Avoid crystallization of the active ingredient. Avoid evaporation/volatilization of the solvent. Avoid heat. Avoid direct sunlight. Avoid excessive temperatures. Avoid excess pressure.

Thermal decomposition: > 50 °C

To avoid thermal decomposition, do not overheat. Decomposition rate increases above the indicated temperature. May decompose violently. Explosive decomposition.

Substances to avoid: heavy metal compounds (e.g. rust), reducing agents, oxidizing agent, acids, bases

Hazardous reactions: Reacts with alkalies. Reacts with oxidizing agents. Reacts with nitrites. Reacts with nitrates. Reacts with heavy metal compounds (e.g. rust). Reacts with various metals. The crystallized product is capable of explosion when heated. Evaporation/volatilization of the solvent causes a product crystallization which is capable of explosion.

Hazardous decomposition products: ammonia, nitrogen oxides

Disposal considerations

Dilute with plenty of water.

Oxidize with sodium hypochlorite or hydrogen peroxide. The indicated conversion should take place only in small portions because of gas formation. Contact manufacturer.

Contaminated packaging: Uncleaned empties should be disposed of in the same manner as the contents. Contaminated packaging should be emptied as far as possible; then it can be passed on for recycling after being thoroughly cleaned.
