SPECIAL FIRE & EXPLOSION HAZARDS: Never use welding or cutting torch on or near drum (even empty) because product (even just residue) can ignite explosively. All five-gallon pails and larger metal containers including tank cars and tank trucks should be grounded and/or bonded when material is transferred. Vapors are heavier than air and may travel along the ground or may be moved by ventilation and ignited by pilot lights, other flames, sparks, heaters, smoking, electric motors, static discharge, or other ignition sources at locations distant from material handling point.

INFA CODES: Health – 1 Flammability – 3 Reactivity – 0 **********************SECTION V – HEALTH HAZARD DATA*********************** PERMISSIBLE EXPOSURE LEVEL: 200 PPM THRESHOLD LIMIT VALUE: 200 PPM (see Section II) EFFECTS OF ACUTE OVEREXPOSURE:

EYES: Exposure may cause mild eye irritation. Symptoms may include stinging, tearing and redness. SKIN: Exposure causes skin irritation. Prolonged or repeated exposure may dry the skin. Symptoms

may include redness, burning, drying and cracking, skin burns and skin damage. Pre-existing skin disorders may be aggravated by exposure to this material. SKIN ABSORPTION IS POSSIBLE, but harmful effects are not expected from this route of exposure under normal conditions of handling and use.

BREATHING: Exposure to vapor or mist is possible. SHORT TERM INHALATION TOXICITY IS LOW. Breathing small amounts during normal handling is not likely to cause harmful effects, breathing large amounts may be harmful. SYMPTOMS ARE MORE TYPICALLY SEEN AT AIR CONCENTRATIONS EXCEEDING THE RECOMMENDED EXPOSURE LIMITS. SYMPTOMS OF EXPOSURE MAY INCLUDE: irritation (nose, throat, respiratory tract), pre-existing lung disorders, e.g., asthma like conditions, may be aggravated by exposure to this material, central nervous system depression (dizziness, drowsiness, weakness, fatigue, nausea, headache, unconsciousness).

SWALLOWING: Single oral toxicity is low. Swallowing small amounts during normal handling is not likely to cause harmful effects, swallowing large amounts may be harmful. SYMPTOMS MAY INCLUDE: central nervous system depression (dizziness, drowsiness, weakness, fatigue, nausea, headache, and unconsciousness). THIS MATERIAL CAN ENTER THE LUNGS DURING SWALLOWING OR VOMITING AND CAUSE LUNG INFLAMMATION AND/OR DAMAGE.

FIRST AID: IF ON THE SKIN: Remove contaminated clothing. Flush exposed area with large amounts of water. If

skin is damaged, seek immediate medical attention. If skin is not damaged and symptoms persist, seek medical attention.

RubberLoc Cleaner(A) Page 11 of 12

IF IN EYES: If symptoms develop, move individual away from exposure and into fresh air. Flush eyes

gently with water while holding eyelids apart. If symptoms persist or there is any visual difficulty, seek medical attention.

IF SWALLOWED: DO NOT induce vomiting. This material is an aspiration hazard. If individual is drowsy or unconscious, place on left side with the head down. Seek medical attention. If possible, do not leave individual unattended.

IF BREATHED: If symptoms develop move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet, seek immediate medical attention.

PRIMARY ROUTES OF ENTRY: Inhalation, skin contact, eye contact and skin absorption. EFFECTS OF CHRONIC OVEREXPOSURE: Based on animal studies, exposure to Methyl Ethyl Ketone

(MEK) increases the onset of peripheral neuropathy caused by exposure to Methyl Butyl Ketone (MBK) and/or N-Haxine, and/or Ethyl Butyl Ketone. MEK alone has not been shown to cause peripheral neuropathy. This material (or a component) has been shown to cause harm to the fetus in laboratory animal studies. The relevance of these findings to humans is uncertain. Based on the available information, this material cannot be classified with regard to carcinogenicity. This material is not listed as a carcinogen by IARC, NTP or OSHA. OVEREXPOSURE TO THIS MATERIAL (or its components) has been suggested as a cause of the following effects in laboratory animals, and may aggravate pre-existing disorders of these organs in humans: mild reversible liver effects, mild reversible kidney effects.

*************************SECTION VI – REACTIVITY DATA************************** HAZARDOUS POLYMERIZATION: Cannot occur STABILITY: Stable INCOMPATIBILITY: Avoid contact with strong oxidizing agents ******************SECTION VII – SPILL OR LEAK PROCEDURES***************** STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:

SMALL SPILL: Absorb liquid on vermiculite, floor absorbent material. LARGE SPILL: Eliminate all ignition sources (flares, flames, including pilot lights, electrical sparks).

Persons not wearing protective equipment should be excluded from area of spill until clean up has been completed. Stop spill at source. Prevent from entering drains, sewers, streams or other bodies of water. Prevent from spreading. If runoff occurs, notify authorities as required. Pump or vacuum transfer spilled product to clean containers for recovery. Absorb unrecoverable product. Transfer to contaminated absorbent, soil and other materials to containers for disposal. Prevent run-off to sewers, streams or other bodies of water. If run-off occurs, notify proper authorities as required that a spill has occurred.

WASTE DISPOSAL METHOD: SMALL SPILL: Dispose of in accordance with all local, state and federal regulations. LARGE SPILL: Dispose of in accordance with all applicable local, state and federal regulations.

************SECTION VIII – PROTECTIVE EQUIPMENT TO BE USED************ RESPIRATORY PROTECTION: If workplace exposure limit(s) of product or any component is exceeded

(see Section II), a NIOSH/MSHA approved air supplied respirator is advised in absence of proper environmental control. OSHA regulations also permit other NIOSH/MSHA respirators (negative pressure

type) under specified conditions (see your industrial hygienist). Engineering or administrative controls

should be implemented to reduce exposure. VENTILATION: Provide sufficient mechanical (general and/or local exhaust) ventilation to maintain exposure

below TLV(s). PROTECTIVE GLOVES: Wear resistant gloves (consult your safety equipment supplier). EYE PROTECTION: Chemical splash goggles in compliance with OSHA regulations are abused, however,

OSHA regulations also permit other type safety glasses. Consult your safety representative. OTHER PROTECTIVE EQUIPMENT: To prevent repeated or prolonged skin contact, wear impervious

clothing and boots. ***************************SECTION IX – SHIPPING DATA*************************** DOT SHIPPING NAME: Methyl Ethyl Ketone TECHNICAL SHIPPING NAME: Methyl Ethyl Ketone DOT HAZARD CLASSIFICATION: 3 UN/NA: UN-1193 DOT LABELS REQUIRED: Red label, Flammable Liquid DOT PLACARDS REQUIRED: Flammable Liquid (3)

liquid, and/or solid), all hazard precautions given in the data sheet must be observed. WARNING: Sudden release of hot organic vapors or mists from process equipment operating at elevated

temperature and pressure, or sudden ingress of air into vacuum equipment may result in ignition without the presence of obvious ignition sources. Published “auto ignition” or “ignition” temperature values cannot be treated as safe operating temperatures in chemical processes without analysis of the actual process conditions. Any use of this product in elevated temperature processes should be thoroughly evaluated to establish and maintain safe operating conditions.
