- Compatibility with Ammonium Phosphate (Fire-fighting Agent)

When test material (2.2 g) and ammonium phosphate (2.1 g) were mixed, the temperature of this mixture was not different from that of the “blank” thermocouple (which was in an empty test tube) by more than 1 °C over a time period of approx. 24 h. Therefore, it was concluded that the test material and ammonium phosphate, when mixed at room temperature, did not mutually react in a hazardous way.

- Compatibility with Zinc (Reducing Agent)

When test material (1.9 g) and zinc powder (1.9 g) were mixed, the temperature of this mixture was not different from that of the “blank” thermocouple (which was in an empty test tube) by more than 4 °C over a time period of approx. 24 h. Therefore, it was concluded that the test material and zinc powder, when mixed at room temperature, did not mutually react in a hazardous way.

- Compatibility with Calcium Hypochlorite (Oxidizing Agent)

When test material (2.1 g) and calcium hypochlorite (2.2 g) were mixed, the temperature of this undisturbed mixture was not different from that of the “blank” thermocouple (which was in an empty test tube) by more than 1 °C over a time period of approx. 24 h. Therefore, based on these results, it was concluded that the test material and calcium hypochlorite, when mixed at room temperature, did not mutually react in a hazardous way.

- Compatibility with Water

When test material (2.0 g) and water (4.0 mL) were mixed, the temperature of this mixture was not different from that of the “blank” thermocouple (which was in an empty test tube; T2 in Figure 4) by more than 5 °C over a time period of approx. 24 h. Therefore, it was concluded that the test material and water, when mixed at room temperature, initially became ‘warm’ (from 22 °C to 26 °C in this experiment) and the temperature of the mixture then equilibrated to ambient temperature. This initial temperature rise (4 °C) was not greater than the EPA criterion of 5 °C, and, therefore, the test material and water did not react in a hazardous way.

Conclusions:

Under the conditions of this study, the test material did not pose a hazard due to heat liberation when mixed with zinc powder, ammonium phosphate, calcium hypochlorite and water.

Executive summary:

The oxidation/reduction properties and chemical compatibility of the test material with zinc powder, ammonium phosphate, calcium hypchlorite, water and cellulose powder was investigated in accordance with the standardised guideline EPA OPPTS 830.6314, under GLP conditions. 

A series of experiments were conducted in which the test matrerial was mixed with zinc powder (reducing agent), ammonium phosphate (firefighting agent), calcium hypochlorite (oxidizing agent) and water. The temperatures of these mixtures were monitored until thermal equilibrium was achieved. In all of these experiments, the temperatures of the undisturbed mixtures were generally not significantly greater than ambient temperature, and were never different from ambient temperature by more than 5 °C, indicating that the test material did not pose a hazard due to heat liberation when mixed with these substances.

Additional information

The oxidation/reduction properties and chemical compatibility of the test material with zinc powder, ammonium phosphate, calcium hypchlorite, water and cellulose powder was investigated in accordance with the standardised guideline EPA OPPTS 830.6314, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
