N-acetylsulphanilyl chloride

Guidance on Safe Use

First-aid measures

Inhalation: Get medical attention immediately. Move exposed person to fresh

air. If it is suspected that fumes are still present, the rescuer should

wear an appropriate mask or self-contained breathing apparatus.

Keep person warm and at rest. If not breathing, if breathing is

irregular or if respiratory arrest occurs, provide artificial respiration or

oxygen by trained personnel. It may be dangerous to the person

providing aid to give mouth-to-mouth resuscitation. If unconscious,

place in recovery position and get medical attention immediately.

Maintain an open airway. Loosen tight clothing such as a collar, tie,

belt or waistband. In the event of any complaints or symptoms, avoid

further exposure.

Ingestion:

Get medical attention immediately. Wash out mouth with water.

Move exposed person to fresh air. Keep person warm and at rest. If

material has been swallowed and the exposed person is conscious,

give small quantities of water to drink. Stop if the exposed person

feels sick as vomiting may be dangerous. Do not induce vomiting

unless directed to do so by medical personnel. If vomiting occurs,

the head should be kept low so that vomit does not enter the lungs.

Chemical burns must be treated promptly by a physician. Never give

anything by mouth to an unconscious person. If unconscious, place

in recovery position and get medical attention immediately. Maintain

an open airway. Loosen tight clothing such as a collar, tie, belt or

waistband.

Skin contact:

Wash the skin immediately with plenty of soap and water; cleaning

immediately with polyethyleneglycol 400 and washing subsequently

with plenty of soap and water would be more effective. Get medical

attention immediately.

Eye contact:

Get medical attention immediately. Immediately flush eyes with

plenty of water, occasionally lifting the upper and lower eyelids.

Check for and remove any contact lenses. Continue to rinse for at

least 10 minutes. Chemical burns must be treated promptly by a

physician.

Fire-fighting measures

Suitable extinguishing media:

In case of fire, use water spray (fog), foam, dry chemical or CO2.

Hazards from the substance or mixture:

In a fire or if heated, a pressure increase will occur and the container

may burst.

Hazardous combustion products:

Decomposition products may include the following materials:

carbon oxides

sulfur oxides

halogenated compounds

Special protective equipment for fire-fighters:

Fire-fighters should wear appropriate protective equipment and selfcontained

breathing apparatus  with a full face-piece

operated in positive pressure mode.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

No action shall be taken involving any personal risk or without suitable training. Keep unnecessary and unprotected personnel from entering. Do not touch or walk through spilt material. Avoid breathing vapour or mist. Provide adequate ventilation.

Environmental precautions:

Avoid dispersal of spilt material and runoff and contact with soil,

waterways, drains and sewers. Inform the relevant authorities if the

product has caused environmental pollution (sewers, waterways, soil

or air).

Handling and storage

Precautions for safe handling

Put on appropriate personal protective equipment.

Eating, drinking and smoking should be prohibited in areas where this

material is handled, stored and processed. Workers should wash

hands and face before eating, drinking and smoking. Persons with a

history of skin sensitisation problems or asthma, allergies or chronic

or recurrent respiratory disease should not be employed in any

process in which this product is used. Do not get in eyes or on skin or

clothing. Do not breathe vapour or mist. Do not ingest. Use only with

adequate ventilation. Wear appropriate respirator when ventilation is

inadequate. Keep in the original container or an approved alternative

made from a compatible material, kept tightly closed when not in use.

Empty containers retain product residue and can be hazardous.

Conditions for safe storage, including any incompatibilities

Store in accordance with local regulations. Store in original container

protected from direct sunlight in a dry, cool and well-ventilated area,

away from incompatible materials  and food and

drink. Keep container tightly closed and sealed until ready for use.

Containers that have been opened must be carefully resealed and

kept upright to prevent leakage. Do not store in unlabelled

containers. Use appropriate containment to avoid environmental

contamination.

Exposure controls / personal protection

Exposure controls

Use only with adequate ventilation. If user operations generate dust,

fumes, gas, vapour or mist, use process enclosures, local exhaust

ventilation or other engineering controls to keep worker exposure to

airborne contaminants below any recommended or statutory limits.

Personal protection measures

Respiratory protection: Use a properly fitted, air-purifying or air-fed respirator complying with

an approved standard if a risk assessment indicates this is

necessary. Respirator selection must be based on known or

anticipated exposure levels, the hazards of the product and the safe

working limits of the selected respirator.

Recommended: Combination filter, e.g. DIN 3181 ABEK if product

forms vapours . Wear breathing apparatus with separate air supply

(compressed air respirator, tube apparatus) at higher concentrations.

Hand protection: Chemical-resistant, impervious gloves complying with an approved

standard should be worn at all times when handling chemical

products if a risk assessment indicates this is necessary. After

contamination with product change the gloves immediately and

dispose of them according to relevant national and local regulations

Recommended: (< 1 hour) Fluorinated rubber - FKM , Butyl rubber -

IIR

Eye protection: Safety eyewear complying with an approved standard should be

used when a risk assessment indicates this is necessary to avoid

exposure to liquid splashes, mists, gases or dusts.

Recommended: Tightly fitting safety goggles.

Skin protection: Personal protective equipment for the body should be selected

based on the task being performed and the risks involved and should

be approved by a specialist before handling this product.

Recommended: chemical-resistant protective suit

Hygiene measures: Wash hands, forearms and face thoroughly after handling chemical

products, 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. Ensure that eyewash stations and safety

showers are close to the workstation location.

Stability and reactivity

Stability and reactivity

Hazardous decomposition products

Under normal conditions of storage and use, hazardous

decomposition products should not be produced.

Chemical stability

The product is stable.

Possibility of hazardous reactions:

Under normal conditions of storage and use, hazardous reactions will not occur.

 

Keep away from the following materials: alkalis , amines , phenol , water .

Disposal considerations

Examine possibilities for re-utilisation. Product residues and

uncleaned empty containers should be packaged, sealed, labelled,

and disposed of or recycled according to relevant national and local

regulations. Where large quantities are concerned, consult the

supplier. When uncleaned empty containers are passed on, the

recipient must be warned of any possible hazard that may be caused

by residues. For disposal within the EC, the appropriate code

according to the European Waste List (EWL) should be used. It is

among the tasks of the polluter to assign the waste to waste codes

specific to industrial sectors and processes according to the

European Waste List (EWL).
