First-aid measures

Never give fluids or induce vomiting if patient is unconscious or is having convulsions.

Skin Contact

Immediate, continued and thorough washing in flowing water for at least 30 minutes is imperative while removing contaminated clothing. Prompt medical consultation is essential. Wash clothing before reuse. Destroy contaminated leather items.

Eye Contact

Wash immediately and continuously with flowing water for at least 30 minutes. Remove contact lenses after the first 5 minutes and continue washing. Obtain prompt medical consultation, preferably from an ophthalmologist.

Inhalation

Move person to fresh air; if effects occur, consult a physician. Ingestion Do not induce vomiting. Give one glass (ca. 2.5 dL) of water or milk if available and transport to medical facility. Do not give anything by mouth to an unconscious person.

Note to Physician

Due to irritant properties, swallowing may result in burns/ulceration of mouth, stomach and lower gastrointestinal tract with subsequent stricture. Aspiration of vomitus may cause lung injury. Suggest endotracheal/esophageal control if lavage is done. If burn is present, treat as any thermal burn, after decontamination. No specific antidote. Treatment of exposure should be directed at the control of symptoms and the clinical condition of the patient.

Fire-fighting measures

Extinguishing Media

Water fog or fine spray. Carbon dioxide. Dry chemical fire extinguishers. Foam. Alcohol resistant foams (ATC type) are preferred. General purpose synthetic foams (including AFFF) or protein foams may function, but will be less effective.

Extinguishing Media to Avoid

Do not use direct water stream. May spread fire.

Hazardous Combustion Products

During a fire, smoke may contain the original material in addition to combustion products of varying composition which may be toxic and/or irritating.

Protection of Fire-fighters

Wear positive-pressure self-contained breathing apparatus and protective fire fighting clothing (includes fire fighting helmet, coat, trousers, boots and gloves). Avoid contact with this material during fire fighting operations. If contact is likely, wear full chemical resistant clothing with positive-pressure self-contained breathing apparatus. This may not provide sufficient fire protection; consider fighting fire from a remote location. For protective equipment in postfire or non-fire clean-up situations, refer to the relevant sections of this SDS.

Specific Methods of Fire-fighting

Keep people away. Isolate fire area and deny unneccessary entry. Burning liquids may be moved by flushing with water to protect personnel and minimise property damage. Burning liquids may be extinguished by dilution with water. Do not use direct water stream. May spread fire. Fight fire from a protected location or safe distance. Consider use of unmanned hose holder or monitor nozzles. Use water spray to cool fire exposed containers and fire affected zone until fire is out and danger of reignition has passed.

Specific Fire or Explosion Hazards

Violent steam generation or eruption may occur upon application of direct water stream to hot liquids. If polymerisation takes place in a closed container, there is a possibility of a violent rupture of the container.

Accidental release measures

Personal Precautions

Keep unnecessary people away; isolate area and deny unnecessary entry. Large spills: Evacuate area. Only trained and properly protected personnel should be involved in cleanup operations.

Environmental Precautions

Contain liquid to prevent contamination of soil, surface water or ground water. Prevent from entering sewers or drains.

Methods of Cleaning Up

Contain with dike. Cover and soak up with a suitable absorbent material, such as: Clay. Sand. Sawdust. Large spills: Recover with vacuum truck.

Handling and storage

Handling

Technical Measures

Use dry air to pad vessels and blow lines. Do not use inert gases (eg. Nitrogen)

Advice for Safe Handling

Avoid breathing vapours. Avoid contact with eyes, skin and clothing. Wash hands and exposed skin before eating, drinking or smoking and after work. Clothing to be laundered before reuse.

Storage

Store in a cool, dry place. Store between 15 and 25 deg.C. Small samples should be stored in dark brown bottles in the absence of initiators, heat or UV light. Store in containers made of: Aluminium. Glass. Mild steel coated with a baked phenolic resin.

This product contains methyl ether of hydroquinone (MEHQ) as an inhibitor. MEHQ requires the presence of dissolved oxygen to maintain its activity. Consequently, check inhibitor content of stored monomer regularly and introduce air periodically if storage over 6 months is anticipated. Never bubble nitrogen through monomer in storage, or blow lines with nitrogen; essential oxygen will be depleted. Uninhibited monomer vapours can polymerise and plug relief devices. Maintain inhibitor and dissolved oxygen level. Do not purge containers of this material with nitrogen or other inert gases.

Exposure controls / personal protection

Prevents all emissions.

Personal Protective Equipment

- Respiratory Protection

When respiratory protection is required for certain operations, use an approved air-purifying respirator.

- Skin Protection

Use protective clothing chemically resistant to this material. Selection of specific items such as face shield, gloves, boots, apron, or full body-suit will depend on operation. Safety shower should be located in immediate work area. Remove contaminated clothing immediately, wash skin area with soap and water, and launder clothing before reuse or dispose of properly. Items which cannot be decontaminated, such as shoes, belts and watchbands, should be removed and disposed of properly.

- Eye/Face Protection

Use chemical goggles. Wear a face-shield which allows use of chemical goggles, or wear a full-face respirator, to protect face and eyes when there is any likelihood of splashes. Eye wash fountain should be located in immediate work area. If exposure causes eye discomfort, use a full-face respirator.

Stability and reactivity

Chemical Stability

Stable under recommended storage conditions. Unstable at elevated temperatures.

Conditions to Avoid

Avoid high temperatures (at or near flash point), open flame, sparks and direct sunlight. Free radical initiators. Do not blanket or purge with an inert gas to avoid depleting the oxygen concentration.

Materials to Avoid

Avoid contact with: Peroxides. Free radical initiators. Iron. Inert gases (eg. Nitrogen).

Hazardous Decomposition Products

Decomposition products depend upon temperature, air supply and the presence of other materials.

Hazardous Polymerisation

Hazardous polymerisation can occur under certain conditions such as: High temperatures. Polymerisation can be catalysed by: Free radical initiators. Iron. Rust. Ultraviolet light. Uninhibited monomer vapours can polymerise and plug relief devices. Maintain inhibitor and dissolved oxygen level. Do not purge containers of this material with nitrogen or other inert gases.

Disposal considerations

Any disposal practice must be in compliance with all local and national laws and regulations.
