Toluene-4-sulphonic acid

Guidance on Safe Use

First-aid measures

Inhalation :

Get medical attention immediately. Call a poison center or physician. Remove victim

to fresh air and keep at rest in a position comfortable for breathing. If it is suspected

that fumes are still present, the rescuer should wear an appropriate mask or selfcontained

breathing apparatus. 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.

Ingestion :

Get medical attention immediately. Call a poison center or physician. Wash out

mouth with water. Remove dentures if any. 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. 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 :

Get medical attention immediately. Call a poison center or physician. Flush

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

Wash contaminated clothing thoroughly with water before removing it, or wear gloves.

Continue to rinse for at least 10 minutes. Chemical burns must be treated promptly

by a physician. Wash clothing before reuse. Clean shoes thoroughly before reuse.

Eye contact :

Get medical attention immediately. Call a poison center or physician. 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.

Protection of first-aiders :

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

suspected that fumes are still present, the rescuer should wear an appropriate mask

or self-contained breathing apparatus. It may be dangerous to the person providing

aid to give mouth-to-mouth resuscitation. Wash contaminated clothing thoroughly

with water before removing it, or wear gloves.

Notes to physician :

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

Suitable extinguishing media : User an extinguishing agent suitable for the surrounding file.

Special exposure hazards :

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

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.

Hazardous thermal decomposition products :

Decomposition products may include the following materials:

carbon dioxide

carbon monoxide

sulfur oxides

Special protective equipment for fire-fighters :

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

Personal precautions :

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. Do not breathe vapour or mist.

Provide adequate ventilation. Wear appropriate respirator when ventilation is

inadequate. Put on appropriate personal protective equipment.

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).

Methods for cleaning up :

Stop leak if without risk. Move containers from spill area. Approach the release from

upwind. Prevent entry into sewers, water courses, basements or confined areas.

Wash spillages into an effluent treatment plant or proceed as follows. Contain and

collect spillage with non-combustible, absorbent material e.g. sand, earth, vermiculite

or diatomaceous earth and place in container for disposal according to local

regulations. Dispose of via a licensed waste disposal contractor. Contaminated

absorbent material may pose the same hazard as the spilt product.

Handling and storage

Handling :

Put on appropriate personal protective equipment (see Section 8). 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. Remove contaminated clothing and protective equipment before entering

eating areas. Do not get in eyes or on skin or clothing. Do not breathe vapour or mist.

Do not ingest. If during normal use the material presents a respiratory hazard, use

only with adequate ventilation or wear appropriate respirator. 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. Do not reuse container.

Storage : 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 (see section 10) and food and drink. Store locked up. 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.

Packaging materials Recommended : Use original container.

Exposure controls / personal protection

Occupational exposure controls :

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.

Environmental exposure controls :

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.

Respiratory protection :

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.

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.

Eye protection : Safety eyewear complying with an approved standard should be used when a risk
