Additional information

Critical point: 67°C at 3960 kPa (INRS).

Relative density (water = 1): 1.5 (NIOSH), 1.538 at 25°C (INRS) (NB: applies to liquefied gas).

Relative gas density (air = 1): 5.1 (NIOSH), 5.14 (calculated), 5.3 (INRS).

The vapour is heavier than air and may accumulate in low ceiling spaces causing deficiency of oxygen (NIOSH, INRS).

Not combustible. Heating will cause rise in pressure with risk of bursting (NIOSH -NB: applies to liquefied gas in closed recipient).

On contact with hot surfaces or flames, thermal decomposition gives off irritant or toxic fumes including hydrogen bromide, hydrogen fluoride, Br2 (NIOSH, INRS).

At high temperature and in contact with water, liberates acids by hydrolysis or catalytic decomposition, leading to metal corrosion (INRS).

Attacks plastic, rubber and coatings (NIOSH).

Reacts violently with sodium, potassium, baryum, molten aluminium, magnesium, zinc (INRS).
