Possible consequences for health

----------------------------------------------------------------------

At inhalation:

Causes irritation in a nose and a throat. Concentration above maximum concentration limit can cause a headache, dizziness, nausea, short wind, vomiting. Higher concentration can cause oppression of the central nervous system and loss of consciousness.

At intake:

Can make belly-ache, sick. Hit in lungs can cause serious injuries of lungs and demands emergency medical service.

At contact with skin:

Causes irritation of skin. Symptoms include reddening, an itch and pain. Can get through skin with possible system effects.

At hit in eyes:

Couples irritate eyes. Splashes can cause painful irritations and injuries of eyes.

Chronic influence:

Long contact with skin can injure skin and cause dermatitis. Chronic influence can cause impact on the central nervous system.

Aggravation of earlier existing conditions:

Persons with already existing violations and diseases of skin, an eye, with the broken respiratory function can be more susceptible to substance influence.

4. Measures of first aid

At inhalation:

To take out on fresh air. If there is no breath carry out artificial ventilation of lungs. If breath is complicated, give oxygen. To ask for medical care.

At intake:

Danger at aspiration. At a proglatyvaniye, vomiting can spontaneously arise, but NOT CAUSE. If vomiting occurs, hold the head below hips to prevent aspiration in lungs. Never give anything in a mouth to the person who fainted. To immediately call the doctor.

At contact with skin:

Immediately wash out skin a large amount of water with soap within at least 15 minutes, deleting the polluted clothes and footwear. To ask for medical care. Wash clothes before a reuse. To carefully clear footwear before a reuse.

At hit in eyes:

Immediately wash out eyes a large amount of water within not less than 15 minutes, lifting the upper and lower eyelids. To ask for medical care.

5. Fire prevention

Fire:

Flash temperature: -6 °C (16F) CC

Spontaneous ignition temperature: 404 °C (759F)

Inflammability limits in % air on volume:

NPVK: 1.4; VPVK: 11.4

Very easily ignites.

Explosion:

At a temperature flash temperatures are higher, steam-air mixes are explosive within noted above. Couples can proceed on a surface to a remote source of ignition / flash and give a boomerang effect. Connection of a product with strong oxidizers can lead to the fire. Tight containers can explode when heating. It is sensitive to static categories.

Fire-prevention system:

Powder, foam or carbon dioxide. Spraying of water can be used for the places which are affected by the fire: containers, dilution of passages to nonflammable mixes, the protection of personnel trying to stop leak and dispersion of vapors.

Special information:

In case of fire it is necessary to put on a full protective suit and the approved NIOSH - the respiratory device with a full mask working under pressure or in the mode of positive pressure. This product is a flammable liquid therefore it has to be protected from sparks, an open flame, hot surfaces and sources of heat and ignition.

6. Measures at casual leaks

To air the place of flood or to remove all sources of ignition. To use appropriate means of individual protection as it is specified in section 8. To isolate areas of danger. To bring all personnel out of a leak zone. To collect and isolate leak if it is possible. Not to use radio-controlled tools and the equipment. To collect liquid in the suitable container or to absorb inert material (for example, vermiculite, dry sand, the earth) and to place in the container for chemical waste. It is not necessary to use combustible materials, such as wood sawdust. Not to wash away in the sewerage! If leak or flood does not ignite, to use the sprayed water for dispersal of vapors to protect the personnel trying to stop leak. Rules (CERCLA) demand the reporting of floods and emissions in the soil, water and air in reporting units. Free number for the National center of reaction of a coast guard of the USA is (800) 424-8802.

JT Baker SOLUSORB solvent is recommended for collecting flood of this product.

7. Address and storage

Protection against physical impacts. To store in the dry, cool, well aired place, far from heat sources. The isolated storage is preferable. To store separately from incompatible products. Containers have to be fixed and grounded when transporting to avoid static sparks. In places storage and uses of a product is forbidden to be smoked. To use only neutral / not subject developments of static electricity and sparks tools and the equipment, including it is necessary to use explosion-proof ventilation. Empty containers from under this material can be dangerous as they keep the product remains (vapors, liquid); to observe all precautionary measures listed for a product.

8. Control of influence / means of personal protection

Limits of influence and concentration in air:

- OSHA Maximum permissible concentration (PEL):

200 parts on one million (TWA)

- ACGIH Maximum permissible (maximum concentration limit):

200 parts on one million (TWA), 300 per milles (STEL)

Ventilating system:

The system of local and/or main ventilation for maintenance admissible is recommended to concentration in air in a working zone. Local exhaust ventilation, is usually more preferable as it can control emissions of the polluting substance, preventing its distribution on all working zone. Address the document ACGIH, Industrial ventilation, the Management on the Recommended practice, the last edition, for obtaining detailed information. To use the explosion-proof equipment.

The personal Respirators (Approved by NIOSH):

If the limit of concentration of a product in air is exceeded, and it is not possible to use technical means of control, it is necessary to use the closed front masks respirators with the organic replaceable filter protecting at the increased concentration by 50 times or the maximum concentration of use established by the relevant producer of respirators. For emergency situations or cases when levels of influence are not known, use a full front mask respirator with positive pressure, respirators with air supply. ATTENTION: respirators with function of purification of air do not protect workers from a lack of oxygen.

Protection of skin:

To wear impenetrable protective clothes, including boots, gloves, raincoats, aprons, in appropriate cases, for prevention of contact with skin. Butyl rubber is suitable material for overalls of personal protection.

Protection of eyes:

Use chemical goggles and/or a mask on the person, for protection against splashes. Provide existence of means for fast washing of eyes in a working zone.
