Sec. 8

Potential Health Effects

Primary Entry Routes: Inhalation and Dermal

Target Organs: Central nervous System and Heart

Acute Effects

Inhalation: Excessive inhalation of vapors can cause nasal and respiratory irritation, dizziness, weakness fatigue, nausea, headache, possible unconsciousness and even asphyxiation.

Eye: May cause irritation, redness, tearing, and blur vision.

Skin: Contact with liquid may cause frostbite. Prolonged or repeated contact can cause moderate dermatitis.

Ingestion: Ingestion is not considered a potential route of exposure

Carcinogenicity: IARC, NTP, and OSHA do not list XTend-It as a carcinogen.

Medical Conditions Aggravated by Long-Term Exposure:

Chronic Effects: No chronic health effects known.

Section 4 - First Aid Measures

Inhalation: Remove source(s) of contamination and move victim to fresh air. If breathing has stopped, give artificial respiration, then oxygen if needed. Contact physician immediately.

Eye Contact: Flush eyes with plenty of water. If irritation persists, seek medical attention.

Skin Contact: In case of skin contact, wash thoroughly with soap and water, treat for frostbite.

Ingestion: Ingestion is unlikely route of exposure. Do not induce vomiting unless instructed by a physician.

After first aid, get appropriate in-plant, paramedic, or community medical support.

Note to Physicians:

Because of possible disturbance of cardiac rhythm, catecholamine drugs, such as epinephrine, should be used only in situations of emergency life support.

Flash Point: -42 F

Flash Point Method: CC

LEL: 3.4 %

UEL: 18.0 %

Flammability Classification: OSHA--Flammable Liquid Class IA DOT--Consumer Commodity ORM-D

Extinguishing Media: Water Fog, Dry Chemical, and Carbon Dioxide Foam

Unusual Fire or Explosion Hazards: Vapors confined in a poorly ventilated area may be ignited by a spark or flame. Vapors may travel considerable distances to source of ignition. Vapors are heavier than air and may accumulate in low areas. Containers may rupture or explode under fire conditions. Hazardous decomposition products may be formed. Material can accumulate static charges, which can cause an incendiary electrical discharge. Empty containers retain product residue and can be dangerous

Fire-Fighting Instructions: Do not release runoff from fire control methods to sewers or waterways.

Fire-Fighting Equipment: Because fire may produce toxic thermal decomposition products, wear a self-contained breathing apparatus (SCBA) with a full facepiece operated in pressure-demand or positive-pressure mode.

Section 6 - Accidental Release Measures

Spill /Leak Procedures: Avoid breathing vapors. Evacuate area until vapor has been dispersed. Remove all sources of ignition. Stop or reduce discharge if it can be done safely.

Regulatory Requirements: Follow applicable OSHA regulations (29 CFR 1910.120).

Section 7 - Handling and Storage

Handling Precautions: Minimize breathing of vapors and avoid prolonged or repeated contact with skin. Wear proper protective equipment. If ventilation is not sufficient, wear proper respiratory equipment. Do not use near ignition sources. Contents under pressure. Do not puncture or incinerate.

Storage Requirements: Store in cool dry, well-ventilated area away from all sources of ignition. Empty container may contain residues, which are hazardous. Do not store at temperature above 120F.

Section 8 - Exposure Controls / Personal Protection

Ventilation: Provide general or local exhaust ventilation systems to maintain airborne concentrations below OSHA PELs (Sec. 2). Local exhaust ventilation is preferred because it prevents contaminant dispersion into the work area by controlling it at its source.

Administrative Controls:

Respiratory Protection: Seek professional advice prior to respirator selection and use. Follow OSHA respirator regulations (29 CFR 1910.134) and, if necessary, wear an MSHA/NIOSH-approved respirator. Select respirator based on its suitability to provide adequate worker protection for given working conditions, level of airborne contamination, and presence of sufficient oxygen. For emergency or nonroutine operations (cleaning spills, reactor vessels, or storage tanks), wear an SCBA. Warning! Air-purifying respirators do not protect workers in oxygen-deficient atmospheres. If respirators are used, OSHA requires a written respiratory protection program that includes at least: medical certification, training, fit testing, periodic environmental monitoring, maintenance, inspection, cleaning, and convenient, sanitary storage areas.

Protective Clothing/Equipment: Wear chemically protective gloves, boots, aprons, and gauntlets to prevent prolonged or repeated skin contact. Wear protective eyeglasses or chemical safety goggles, per OSHA eye- and face-protection regulations (29 CFR 1910.133). Contact lenses are not eye protective devices. Appropriate eye protection must be worn instead of, or in conjunction with contact lenses.

Comments: Never eat, drink, or smoke in work areas. Practice good personal hygiene after using this material, especially before eating, drinking, smoking, using the toilet, or applying cosmeticsEngineering Controls:
