KILLER GAS - THE LETHAL DANGERS OF HYDROGEN SULPHIDE (H2S)

Hydrogen Sulphide (H2S) is a colourless gas with a distinctive odour of rotten eggs. It is a toxic gas and the health hazard depends upon both the duration of exposure and the concentration.

Sense of smell to H2S is lost at concentrations of 100 ppm, so people may have little warning of the presence of the gas at dangerous concentrations. At levels above 700 ppm, H2S can kill instantly.

The video takes on the premise of an unseen killer that stalks a vessel. Through an investigative and dramatised documentary approach, with a sinister underlying theme, the programme will help to convince the viewer to be more vigilant to his/her surroundings and the dangers that lurk around the ship. The accompanying booklet gives more detail and can be used as both a learning and reference tool.

The target audience is all marine personnel, covering a broad range from deck crew to Masters, including land based marine workers. The overall aim of the three elements is to facilitate an awareness of the dangers and impact caused by H2S and to promote broader detection and personal safety.
