Any other information on results incl. tables

On combustion or on thermal decomposition (following the evaporation of water) the substance releases:

(Carbon oxides (CO + CO2)).

corrosive vapours. (Phosphorus oxides).

Above 200°C releases:(Phosphine)

The phosphine will burn on to phosphorus pentoxide unless there is insufficient fresh air

BHMT-H was also reported to attacks many metals thereby releasing highly flammable gas (hydrogen) which generates fire or explosion hazards.

Applicant's summary and conclusion

Conclusions:
The test substance was observed to generate phosphine when heated to a high temperature of above 200°C.
