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 materials 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.

In hot acid solution this material can undergo spontaneous hydrolysis, liberating much heat.|Incompatibilities: Contact with strong oxidizers may cause fires and explosions. Contact with hot water may cause formation of large amounts of steam.|Acids, hot water [Note: Elevated temperatures cause a highly exothermic reaction with water].

Ammonium sulfamate is an indirect food additive for use only as a component of adhesives.

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 sealed with an impermeable flexible membrane liner./ Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water.|Environmental considerations: Water spill: Add calcium hypochlorite.

Liquid formulations may be reduced to solid phase by evaporation. Dry sweeping of solids is always hazardous: these should be removed by vacuum cleaning, or by dissolving them in water, or other solvent in the factory environment. /Pesticides/|Persons not wearing protective equipment and clothing should be restricted from areas of spills until cleanup has been completed. If ammonium sulfamate is spilled, the following steps should be taken: 1. Ventilate area of spill. 2. Collect spilled material in the most convenient and safe manner and deposit in sealed containers. Liquid containing ammonium sulfamate should be absorbed in vermiculite, dry sand, earth, or similar material.|Transfer gradually into a large container of cold water while stirring. After completion of reaction, neutralize with either 3M-HCl or 6M-NH4OH according to the pH of the solution.

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.|Avoid prolonged contact of skin with strong solution. In case of contact, wash off with plenty of water.|If material not on fire and not involved in fire: Keep material out of water sources and sewers. Keep Material out of water sources and sewers.

Fertility of quail was not affected by 2 periods of 10 days continuous administration of mixed feed containing ammonium sulfamate at rate of 150 mg/kg/day.

The use of urea-formaldehyde resins as temporary binders in the firing of refractories and ceramics at high temperatures can lead to the formation of substantial deposits of ammonium sulfamate in the cooler parts of kilns, should a fuel oil containing appreciable amount of sulfur be used for firing. Ammonia from decomposition of the resin combines with sulfur trioxide to form ammonium sulfamate which accumulates as either a solidified deposit in flues or as a white deposit on walls. ...
