Guidance on Safe Use

First-aid measures

4.1. Description of necessary first-aid measures:

Inhalation:

If inhaled, remove victim to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.

Get medical attention.

Skin:

In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated

clothing and shoes. Get medical attention immediately. Wash clothing before reuse. Thoroughly clean shoes before

reuse.

Eyes:

In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical attention

immediately.

Ingestion:

If swallowed, DO NOT induce vomiting. Get medical attention immediately. If victim is fully conscious, give a cupful of

water. Never give anything by mouth to an unconscious person.

4.2. Most important symptoms/effects, acute and delayed:

For most important symptoms and effects (acute and delayed), see Section 2 (Hazard Statements and Supplemental

Information) and Section 11 (Toxicology Information) of this SDS.

4.3. Indication of immediate medical attention and special treatment needed, if necessary:

Unless otherwise noted in Notes to Physician, no specific treatment noted; treat symptomatically.

Fire-fighting measures

Extinguishing media (suitable):

Water spray, Carbon dioxide (CO2), Foam, Dry chemical

Protective equipment:

Fire fighters and others who may be exposed to products of combustion should wear full fire fighting turn out gear

(full Bunker Gear) and self-contained breathing apparatus (pressure demand / NIOSH approved or equivalent).

Further firefighting advice:

Cool closed containers exposed to fire with water spray.

Do not use a solid water stream as it may scatter and spread fire.

A solid stream of water can cause frothing and spattering.

Fire fighting equipment should be thoroughly decontaminated after use.

Do not allow run-off from fire fighting to enter drains or water courses.

Fire and explosion hazards:

When burned, the following hazardous products of combustion can occur:

Carbon oxides

Sulphur oxides

hydrogen sulfide

Hazardous organic compounds

Accidental release measures

Personal precautions, Emergency procedures, Methods and materials for containment/clean-up:

Prevent further leakage or spillage if you can do so without risk. Evacuate area of all unnecessary personnel.

Ventilate the area. Avoid generation of vapors. Contain and collect spillage with non-combustible absorbent material

such as clean sand, earth, diatomaceous earth or non-acidic clay and place into suitable properly labeled containers

for prompt disposal. Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains and

sewers. Consult a regulatory specialist to determine appropriate state or local reporting requirements, for assistance

in waste characterization and/or hazardous waste disposal and other requirements listed in pertinent environmental

permits.

Protective equipment:

Appropriate personal protective equipment is set forth in Section 8.

Handling and storage

Handling

General information on handling:

Do not taste or swallow.

Do not get in eyes, on skin, or on clothing.

Avoid breathing vapor or mist.

Keep container tightly closed.

Use only with adequate ventilation.

Wash thoroughly after handling.

Emptied container retains vapor and product residue.

Observe all labeled safeguards until container is cleaned, reconditioned or destroyed.

Storage

General information on storage conditions:

This material is not hazardous under normal storage conditions; however, material should be stored in closed

containers, in a secure area to prevent container damage and subsequent spillage. Store away from heat and

ignition sources. Keep containers tightly closed in a cool, well-ventilated place.

Storage incompatibility – General:

Store separate from:

Alkali metals

Strong oxidizing agents

Strong bases

Reducing agents

Strong acids

Exposure controls / personal protection

Airborne Exposure Guidelines:

1-Dodecanethiol (112-55-0)

US. ACGIH Threshold Limit Values

Time weighted average 0.1 ppm

Only those components with exposure limits are printed in this section. Limits with skin contact designation above have skin contact

effect. Air sampling alone is insufficient to accurately quantitate exposure. Measures to prevent significant cutaneous absorption

may be required. Limits with a sensitizer designation above mean that exposure to this material may cause allergic reactions.

Engineering controls:

Investigate engineering techniques to reduce exposures below airborne exposure limits or to otherwise reduce

exposures. Provide ventilation if necessary to minimize exposures or to control exposure levels to below

airborne exposure limits (if applicable see above).If practical, use local mechanical exhaust ventilation at

sources of air contamination such as open process equipment.

Respiratory protection:

Avoid breathing vapor or mist. Where airborne exposure is likely or airborne exposure limits are exceeded (if

applicable, see above), use NIOSH approved respiratory protection equipment appropriate to the material

and/or its components. Full facepiece equipment is recommended and, if used, replaces need for face shield

and/or chemical goggles. Consult respirator manufacturer to determine appropriate type equipment for a given

application. Observe respirator use limitations specified by NIOSH or the manufacturer. For emergency and

other conditions where there may be a potential for significant exposure or where exposure limit may be

significantly exceeded, use an approved full face positive-pressure, self-contained breathing apparatus or

positive-pressure airline with auxiliary self-contained air supply. Respiratory protection programs must comply

with 29 CFR § 1910.134.

Skin protection:

Wear appropriate chemical resistant protective clothing and chemical resistant gloves to prevent skin contact.

Consult glove manufacturer to determine appropriate type glove material for given application. Wear chemical

goggles, a face shield, and chemical resistant clothing such as a rubber apron when splashing may occur.

Rinse immediately if skin is contaminated. Remove contaminated clothing immediately and wash before reuse.

Clean protective equipment before reuse. Provide a safety shower at any location where skin contact can

occur. Wash thoroughly after handling.

Eye protection:

Where there is potential for eye contact, wear a face shield, chemical goggles, and have eye flushing

equipment immediately available.

Disposal considerations

Waste disposal:

Disposal via incineration is recommended. Dispose of in accordance with federal, state and local regulations.

Consult a regulatory specialist to determine appropriate state or local reporting requirements, for assistance in

waste characterization and/or hazardous waste disposal and other requirements listed in pertinent environmental

permits. Note: Chemical additions to, processing of, or otherwise altering this material may make this waste

management information incomplete, inaccurate, or otherwise inappropriate. Furthermore, state and local waste

disposal requirements may be more restrictive or otherwise different from federal laws and regulations.

Take appropriate measures to prevent release to the environment.
