Sigma HSE UK Ltd
A UK, Sussex-based recycling company has been fined following an explosion and fire at one of their sites. Portsmouth Crown Court heard how a massive explosion occurred at the site on 3 October 2011 in Lingfield, Surrey, following the storage of print toner on site. Eight people were injured (five seriously) as a result of the explosion when toner cartridges being shredded and reprocessed.

The MInimum Ignition Energy (MIE) test is conducted to determine the lowest spark energy that will ignite a powder when dispersed in air, as a dust cloud.An inductive generated spark is selected for mechanical (friction, impact and grinding) or electrical (wire short, electrical contact) spark incendivity analysis. https://sigma-hse.com/testing/dust-powder-testing/
The air over layer test is conducted to establish the onset temperature of exothermic activity of thin layers of material when exposed to elevated atmospheric temperatures. https://sigma-hse.com/testing/thermal-stability-testing/

Burning Behaviour is conducted to assess the behaviour (severity) of combustion propagation through a material deposit on being ignited by an external ignition source. https://sigma-hse.com/testing/dust-powder-testing/
The autoignition temperature or kindling point of a substance is the lowest temperature at which it spontaneously ignites in normal atmosphere without an external source of ignition, such as a flame or spark. https://sigma-hse.com/testing/dust-powder-testing/
This test is conducted to determine the lower and upper concentration limits of flammability of chemicals having sufficient vapour pressure to form flammable mixtures in air at atmospheric pressure at a specific test temperature. https://sigma-hse.com/testing/thermal-stability-testing/
The bulk powder diffusion cell test is conducted to establish the onset temperature of exothermic activity of a material when exposed to elevated atmospheric temperatures.
Viour is conducted to assess the behaviour (severity) of combustion propagation through a material deposit on being ignited by an external ignition source. https://sigma-hse.com/testing/dust-powder-testing/

The air over layer test is conducted to establish the onset temperature of exothermic activity of thin layers of material when exposed to elevated atmospheric temperatures. https://sigma-hse.com/testing/thermal-stability-testing/
Flammability test assess whether a dust/powder will form a flammable atmosphere, supporting flame propagation, when dispersed as a dust cloud in air. It is a purely qualitative test and categorises a material into one of two groups. https://sigma-hse.com/testing/dust-powder-testing/

Flammable limits apply generally to vapors and are defined as the concentration range in which a flammable substance can produce a fire or explosion when an ignition source (such as a spark or open flame) is present. https://sigma-hse.com/testing/gas-vapour-testing/
