If dealing with a spill, and good ventilation is impractical, wear a suitable respirator with organic vapour/acid gas cartridge. Never cut, drill, weld or grind on or near this container. Avoid all contact with skin and wash work clothes frequently. An eye bath and safety shower must be available near the workplace. 10. SPILL PROCEDURES Leak Precaution dyke to control spillage and prevent environmental contamination Handling Spill ventilate contaminated area; recover free liquid with suitable pumps; absorb residue on sand of sawdust, sweep & pick up using plastic or aluminium shovel, & store in closed containers for recycling or disposal; sodium sulphite or sodium carbonate may be used to neutralise the residue 11. DISPOSAL Waste Disposal do not flush to sewer, may be incinerated in approved facility after dissolving in a suitable flammable waste; a rotary kiln with afterburner should be used Containers Drums should be reused. Recondition and pressure test by a licensed reconditioner prior to re-use. Pails must be vented and thoroughly dried prior to crushing and recycling. IBCs (intermediate bulk containers): polyethylene bottle must be pressure tested & recertified at 30 months. Replace at 60 months (5yrs). Steel containers must be inspected, pressure tested & recertified every 5 years.

Never cut, drill, weld or grind on or near this container, even if empty 12. ENVIRONMENTAL INFORMATION Bioaccumulation this product is not a bioaccumulator Biodegradation this product degrades readily and rapidly in the presence of oxygen complete in 48-72hr Abiotic Degradation this product reacts with atmospheric hydroxyl radicals; its estimated half-life in air is 41 hours Mobility in soil, water this product is water soluble and may move readily in soil and water but rapid degradation and uptake by soil organisms may greatly limit movement Aquatic Toxicity LC50 (Fish, 96hr) 118mg/litre (oncorhynchus mykiss), 10mg/litre (morone saxatilis), 69mg/litre (salmo salar) & others

Causes burns. Limited evidence of a carcinogenic effect. May cause sensitisation by skin contact. [R:23/24/25-34-40-43] Europe Safety Phrases In case of contact with eyes, rinse immediately plenty of water and seek medical advice. Wear suitable protective clothing, gloves and eye/face protection. In case of accident or if you feel unwell, seek medical advice immediately (show label). Use only in well ventilated areas. [S:26-36/37-45-51] Immediately Dangerous to Life or Health: 20 ppm; NIOSH considers formaldehyde to be a potential occupational carcinogen. Allowable Tolerances: Formaldehyde not more than 1% of pesticide formulation is exempted from the requirement of a tolerance when used as a preservative for formulation in accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops only. OSHA Standards: Permissible Exposure Limit: 8 Hr Time-Weighted Avg 0.75 ppm; 15 Min STEL 2 ppm. NIOSH Recommendations: Recommended Exposure Limit: 10 Hr Time-Weighted Avg: 0.016 ppm. Recommended Exposure Limit: 15 Min Ceiling Value: 0.1 ppm. NIOSH usually recommends that occupational exposures to carcinogens be limited to the lowest feasible concentration. Threshold Limit Values: Ceiling limit 0.3 ppm, sensitization; A2: Suspected human carcinogen. Atmospheric Standards: This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Formaldehyde is produced, as an intermediate or a final product, by process units covered under this subpart. Listed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants. EPA is required to establish and phase in specific performance based standards for all air emission sources that emit one or more of the listed pollutants. Formaldehyde is included on this list.

15. REGULATIONS, contd Federal Drinking Water Guidelines: EPA 1000 ug/l State Drinking Water Guidelines: California 100 ug/l, Florida 600 ug/l, Maine 140 ug/l, Minnesota 1000 ug/l, New Jersey 100 ug/l, Wisconsin 1000 ug/l Clean Water Act Requirements: Formaldehyde is designated as a hazardous substance under section 311(b)(2)(A) of the Federal Water Pollution Control Act and further regulated by the Clean Water Act Amendments of 1977 and 1978. These regulations apply to discharges of this substance. This designation includes any isomers and hydrates, as well as any solutions and mixtures containing this substance. CERCLA Reportable Quantities: Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 100 lb or 45.4 kg. The toll free number of the NRC is (800) 424-8802. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b). Releases of CERCLA hazardous substances are subject to the release reporting requirement of CERCLA section 103, codified at 40 CFR part 302, in addition to the requirements of 40 CFR part 355. Formaldehyde is an extremely hazardous substance (EHS) subject to reporting requirements when stored in amounts in excess of its threshold planning quantity (TPQ) of 500 lbs. RCRA Requirements: As stipulated in 40 CFR 261.33, when formaldehyde, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to Federal and/or State hazardous waste regulations. Also defined as a hazardous waste is any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5). FIFRA Requirements: As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Formaldehyde is found on List A, which contains most food use pesticides and consists of the 194 chemical cases (or 350 individual active ingredients) for which EPA issued registration standards prior to FIFRA, as amended in 1988. Case No: 0556; Pesticide type: fungicide, antimicrobial; Registration Standard Date: 05/31/88; Case Status: OPP is reviewing data from the pesticide's producers regarding its human health and/or environmental effects, or OPP is determining the pesticide's eligibility for reregistration and developing the Reregistration Eligibility Decision (RED) document.; Active ingredient (AI): Formaldehyde; AI Status: The producers of the pesticide has made commitments to conduct the studies and pay the fees required for reregistration, and are meeting those commitments in a timely manner. FDA Requirements: Formaldehyde is an indirect food additive for use only as a component of adhesives. Formaldehyde is a food additive permitted in feed and drinking water of animals. 16.
