Urban Air Quality

Our atmosphere is dynamic. Biological, physical and chemical processes contribute to ‘clean air’, a gas mix which is remarkably well balanced for life and free of toxic gases and particulates.

 

Oxygen is at as high a concentration as enables aerobic organisms such as us to breath easily, whilst not so high as to cause unquenchable forest fires. Carbon dioxide is plentiful enough for plants to grow, both as a source of carbon and in retaining sufficient but not too much warmth from the sun. Elements essential for life such as sulfur and iodine are transported from land to sea in the form of volatile organic compounds (VOCs).

Many gases, which are toxic or harmful to life are removed by chemical and physical adsorption on solid particles (particulates) which ultimately fall out of the air under gravity as dust or rain. What is more, through a series of chemical reactions, including reactions with sunlight (photochemical reactions), the atmosphere is kept almost completely free of specific VOCs released by plants, it would seem to their own and wider advantage. For example, it has been recently established that on being bruised, leaves release VOC messengers (pheromones) that attract predators of leaf eating insects! Read more!

VOCs in HAZMAT and the power of PID detection

An emergency response organisation will greatly increase its effectiveness and the level of protection it offers its employees (Responders) by deploying a photoionisation detector (PID).

Incidents Involving VOCs
Many Hazardous Materials incidents involve volatile organic compounds (VOCs), a vast chemical family that is primarily made up of hydrocarbons such as gasoline, alcohols, methane and acetone as well as the BTEX family which include benzene, toluene, ethylbenzene and xylene. Typically, VOCs have a high vapour pressure at ambient temperatures, meaning the liquid gives off vapour that can be readily detected.

Hazardous Materials Spill Response Procedures

Hazardous Material spills including biological, chemical and radiological materials pose a serious risk if not promptly and properly responded to by the individuals who initially identify the spill and the appropriate emergency response team.

When a Hazardous Materials (HAZMAT) response team arrives at the scene of any incident or accident involving hazardous materials there are many unknown factors which initially need to be identified, so it is critical that First Responders tackle each incident in an accurate and systematic way.
