Section 5. Fire-fighting Measures

Extinguishing media

Suitable extinguishing media:Use water spray, alcohol foam, carbon dioxide, or dry chemical to
extinguish fires. Water stream may be ineffective.
Protective Equipment:Firefighters, and others exposed, wear self-contained breathing
apparatus. Wear full firefighting protective clothing. See SDS Section
8 (Exposure Controls/Personal Protection).
Special Hazards:Keep containers cool by spraying with water if exposed to fire.

Section 6. Accidental Release Measures

Personal precautions Where exposure level is known, wear approved respirator suitable for
level of exposure. Where exposure level is not known, wear approved,
positive pressure, self-contained respirator. In addition to the protective
clothing/equipment in Section 8 (Exposure Controls/Personal
Protection), wear impermeable boots.
Methods for cleaning upRemove sources of ignition. Cover spills with some inert absorbent
material; sweep up and place in a waste disposal container. Flush spill
area with water.
References to other sections:See Sections 8 and 13 for additional information.

Section 7. Handling and Storage

Handling Precautions:Keep in the original container. Keep away from heat, sparks, and open flame. – No smoking. Keep container tightly closed. Ground/Bond container and receiving equipment. Use explosion-proof electrical ventilating, lighting, and other equipment. Use only non-sparking tools. Take precautionary measures against static discharge. Wear protective gloves and eye/face protection. Wash hands thoroughly after handling. Use only outdoors or in a well-ventilated area. Avoid breathing vapors or spray mist.
Special Handling Statements:This material will corrode steel or aluminum at a rate greater than 6.25 mm (0.25 inches/year) @55°C (130° F). It is thus considered to be a corrosive material for transportation purposes. Containers must be bonded and grounded when pouring or transferring material.
Storage Areas containing this material should have fire safe practices and electrical equipment in accordance with applicable regulations and/or guidelines. Standards are primarily based on the material’s flashpoint, but may also take into account properties such as miscibility with water or toxicity. All local and national regulations should be followed. In the Americas, National Fire Protection Association (NFPA) 30: Flammable and Combustible Liquids Code, is a widely used standard. NFPA 30 establishes storage conditions for the following classes of materials: Class I Flammable Liquids, Flashpoint <37.8°C. Class II Combustible Liquids, 37.8°C < Flashpoint <60°C. Class IIIa Combustible Liquids, 60°C < Flashpoint < 93°C. Class IIIb Combustible Liquids, Flashpoint > 93°C.
Storage Temperature: Store at 0° - 30°C (32° - 86°F)
Reason: Quality.

Section 8. Exposure Controls/Personal Protection

Engineering measures:

Utilize a closed system process where feasible. Where this material is not used in a closed system, good enclosure and local exhaust ventilation should be provided to control exposure.

Respiratory Protection:

Where exposures are below the established exposure limit, no respiratory protection is required. Where exposures exceed the established exposure limit, use respiratory protection recommended for the material and level of exposure. Recommended respirators include those certified by NIOSH.

Eye Protection:

Prevent eye and skin contact. Provide eye wash fountain and safety shower in close proximity to points of potential exposure. Wear eye/face protection such as chemical splash proof goggles or face shield.

Skin Protection:

Prevent contamination of skin or clothing when removing protective equipment. Wear impermeable gloves and suitable protective clothing.

Hand Protection:

Nitrile or fluorinated rubber gloves. Consider the porosity and elasticity data of the glove manufacturer and the specific conditions in the work place. Replace gloves immediately when torn or any change in appearance (dimension, color, flexibility, etc.) is noticed.

Additional Advice:

Food, beverages, and tobacco products must not be carried, stored, or consumed where this material is in use. Before eating, drinking, or smoking, wash face and hands thoroughly with soap and water.

Isopropanol has acute oral (rat) and dermal (rabbit) LD50 values of 5.0 g/kg and 12.8 g/kg, respectively. The 4-hour inhalation LC50 (rat) for isopropanol is >16,000 ppm (40.86 mg/L). Acute overexposure to isopropanol vapor may cause mild irritation of the eyes and respiratory tract. Chronic overexposure to isopropanol vapors may cause central nervous system depression, headaches, dizziness, nausea, and staggered gait. Liquid isopropanol may cause moderate to severe eye irritation. In laboratory animal studies, isopropanol has produced fetotoxic effects at levels that were maternally toxic and developmental effects at levels that were maternally non-toxic, and inhalation exposures that produced reduced fetal weight at non-maternally toxic levels. Literature reports chronic exposure has caused kidney problems and testicular effects in laboratory animals.

Acute overexposure to p-toluenesulfonic acid vapor or mist may cause eye, skin, and respiratory irritation. The liquid is a moderate to severe eye and skin irritant. The oral LD50 value in rats is 2.5 g/kg.

The toxicological properties of o-toluene sulfonic acid have not been fully investigated. Acute overexposure to o-toluenesulfonic acid vapor or mist may cause eye, skin, and respiratory irritation. Direct contact with this material may cause moderate eye and skin irritation. The acute oral (rat) LD50 value is estimated to be >2.5 g/kg.

Section 13. Disposal considerations

The information on RCRA waste classification and disposal methodology provided below applies only to the product, as supplied. If the material has been altered or contaminated, or it has exceeded its recommended shelf life, the guidance may be inapplicable. Hazardous waste classification under federal regulations (40 CFR Part 261 et seq) is dependent upon whether a material is a RCRA “listed hazardous waste” or has any of the four RCRA “hazardous waste characteristics.” Refer to 40 CFR Part 261.33 to determine if a given material to be disposed of is a RCRA “listed hazardous waste”; information contained in Section 15 of this SDS is not intended to indicate if the product is a “listed hazardous waste.” RCRA Hazardous Waste Characteristics: There are four characteristics defined in 40 CFR Section 261.21-61.24: Ignitability, Corrosivity, Reactivity, and Toxicity. To determine Ignitability, see Section 9 of this SDS (flash point). For Corrosivity, see Sections 9 and 14 (pH and DOT corrosivity). For Reactivity, see Section 10 (incompatible materials). For Toxicity, see Section 3 (composition). Federal regulations are subject to change. State and local requirements, which may differ from or be more stringent than the federal regulations, may also apply to the classification of the material if it is to be disposed. The Company encourages the recycle, recovery, and reuse of materials, where permitted, as an alternate to disposal as a waste. The Company recommends that organic materials classified as RCRA hazardous wastes be disposed of by thermal treatment or incineration at EPA approved facilities. The Company has provided the foregoing for information only; the person generating the waste is responsible for determining the waste classification and disposal method.
