4.1 Safety Statements: S26-S60-S61-S36

4.1 Exposure Standards and Regulations: Zinc acetate is an indirect food additive for use only as a component of adhesives.
Trace minerals added to animal feeds as nutritional dietary supplements are generally recognized as safe when added at levels consistent with good feeding practice. Zinc acetate is included on this list.
The Approved Drug Products with Therapeutic Equivalence Evaluations List identifies currently marketed prescription drug products, incl zinc acetate, approved on the basis of safety and effectiveness by FDA under sections 505 of the Federal Food, Drug, and Cosmetic Act.
Drug products containing certain active ingredients offered over-the-counter (OTC) for certain uses. A number of active ingredients have been present in OTC drug products for various uses, as described below. However, based on evidence currently available, there are inadequate data to establish general recognition of the safety and effectiveness of these ingredients for the specified uses: zinc acetate is included in skin protectant drug products (wound healing claims only).

4.2 Packing Group: III

4.2 Other Preventative Measures: If material not on fire and not involved in fire: Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Keep up wind. Avoid breathing vapors or dusts. Wash away any material which may have contacted the body with copious amounts of water or soap and water.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
Prevention ... /of metal fume fever/ is a matter of keeping exposure of workers below level of concn currently accepted as satisfactory for working with the metal in industry, preferably by employment of proper local exhaust ventilation to collect fumes at their source. Acceptable respirators are avail commercially but should be used only under suitable conditions. /Zinc/
In all cases where zinc is heated to the point where fume is produced, it is most important to ensure that adequate ventilation is provided. Individual protection is best ensured by education of the worker concerning metal-fume fever & the provision of local exhaust ventilation, or, in some situations by wearing of supplied-air hood or mask.; View all

4.3 Hazard Class: 9

4.3 Hazard Declaration: H302; H319; H410

4.3 Cleanup Methods: Environmental considerations: Land spill: Dig a pit, pond, lagoon, or holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be contained with a flexible impermeable membrane liner./ Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water.
Environmental considerations: Water spill: Neutralize with agricultural lime (CaO), crushed limestone, or sodium bicarbonate. Add soda ash. Adjust pH to neutral (pH 7). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates or greater concentration.

4.4 DisposalMethods: SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
