The following is an example of risk assessment for laboratory process equipment operating at high pressure.


This risk assessment covers operating processes involving the use of chemical reactors (autoclaves) and sealed tube reactions.

Hazard and Risk

The principal hazards arising from the use of high pressure chemical reactors are:

  • trauma wounds caused by disruption and fragmentation of the vessel

  • corrosive or toxic chemicals from vessel failure or leaks from seals and connections

  • fires and explosions caused by the release of flammable or combustible gases or vapours.

If control measures are not in place and maintained, the likely risks are as follows.
