Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Nine samples of FireMaster 100, batch #180, were prepared for hydrolysis by placing approximately one gram of FireMaster 100 in each of nine bottles containing thirty mls of distilled water. The bottles were tightly capped and put on a shaker.
Samples were taken approximately twice weekly and the water tested for pH and bromide ion formation. - GLP compliance:

- Executive summary:
An hydrolysis experiment on FireMaster 100 has been completed. Nine samples of Fire Master 100 (batch #180) were prepared for hydrolysis by placing approximately 1 g of FireMaster 100 in each of nine bottles containing 30 mL of distilled water. The bottles were tightly capped and put on a shaker. Samples were taken approximately twice weekly and the water tested for pH and bromide ion formation. After 900 hours (39 days) no bromide ion formation was detected in any of the samples. The detection limit of the method used was 200 ppm. pH measurements did not show any significant trend when analysed by linear regression analysis at the 95% confidence level. It can be concluded that no hydrolysis occurs under the conditions of this study.
