2-Naphthalenesulfonic acid, 7-[(ethoxycarbonyl)amino]-4-hydroxy-, sodium salt (1:1)

Guidance on Safe Use

First-aid measures

Eye contact:

Immediately flush eyes with plenty of water. occasionally lifting the upper and lower

eyelids. Check for and remove any contact lenses. Get medical attention if irritation

occurs.

Inhalation:

Remove victim to fresh air and keep at rest in a position comfortable for breathing.

Get medical attention if symptoms occur.

Skin contact:

Flush contaminated skin with plenty of water. Remove contaminated clothing and

shoes. Get medical attention if symptoms occur.

Ingestion:

Wash out mouth with water. Remove victim to fresh air and keep at rest in a position

comfortable for breathing. If material has been swallowed and the exposed person

is conscious. give small quantities of water to drink. Do not induce vomiting unless

directed to do so by medical personnel. Get medical attention if symptoms occur.

Protection of first-aiders:

No action shall be taken involving any personal risk or without suitable training.

Indication of any immediate medical attention and special treatment needed

Notes to physician:

Treat symptomatically. Contact poison treatment specialist immediately if large

quantities have been ingested or inhaled.

Specific treatments Symptomatic treatment and supportive therapy as indicated. Following severe

exposure the patient should be kept under medical review for at least 48 hours.

Fire-fighting measures

Use an extinguishing agent suitable for the surrounding fire.

Special precautions for fire·fighters:

Promptly isolate the scene by removing all persons from the vicinity of the incident if

there is a fire. No action shall be taken involving any personal risk or without suitable

training.

Fire-fighters should wear appropriate protective equipment and self-contained

breathing apparatus (SCBA) with a full face-piece operated in positive pressure

mode. Clothing for fire-fighters (including helmets, protective boots and gloves)

conforming to European standard EN 469 will provide a basic level of protection for

chemical incidents.

Accidental release measures

No action shall be taken involving any personal risk or without suitable training.

Evacuate surrounding areas. Keep unnecessary and unprotected personnel from

entering. Do not touch or walk through spilt material. Put on appropriate personal

protective equipment.

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).

Move containers from spill area. Prevent entry into sewers, water courses,

basements or confined areas. Vacuum or sweep up material and place in a

designated, labelled waste container. Dispose of via a licensed waste disposal

contractor.

Handling and storage

Put on appropriate personal protective equipment.

Advice on general:

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

occupational hygiene handled, stored and processed. Workers should wash hands and face before

eating, drinking and smoking. Remove contaminated clothing and protective

equipment before entering eating areas.

Exposure controls / personal protection

Good general ventilation should be sufficient to control worker exposure to airborne contaminants.

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.

Eye/face 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.

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.

Use gloves approved to relevant standards e.g. EN 374 (Europe), F739 (US).

Suitability and durability of a glove is dependent on usage, e.g. frequency and

duration of contact, chemical resistance of glove material and dexterity. Always seek

advice from glove suppliers. Addilional information can be found for instance at

lIIWW.gisbau.de.

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.

Appropriate footwear and any additional skin protection measures should be

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

approved by a specialist before handling this product.

In case of inadequate ventilation wear respiratory protection. 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.

Emissions from ventilation or work process equipment should be checked to ensure

they comply with the requirements of environmental protection legislation. In some

cases, fume scrubbers, filters or engineering modifications to the process

equipment will be necessary to reduce emissions to acceptable levels.

Stability and reactivity

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

Disposal considerations

The generation of waste should be avoided or minimised wherever possible.

Significant quantities of waste product residues should not be disposed of via the

foul sewer but processed in a suitable effluent treatment plant. Dispose of surplus

and non-recyclable products via a licensed waste disposal contractor. Disposal of

this product, solutions and any by-products should at all times comply with the

requirements of environmental protection and waste disposal legislation and any

regional local authority requirements.
