For example, a chemical accident inwhich chlorine gas or cyanide gas isreleased would likely result in
widespread deaths as the plume, or toxiccloud, moved through a populated area

Toxic red sludge from a spill at anindustrial plant in Hungary has reachedthe River Danube,
They said alkaline levels that killed all fish inone river were now greatly reduced, but werebeing monitored.
PM Viktor Orban called the spill an "ecological
tragedy". There are fears the mud, whichburst out of a reservoir on Monday, couldpoison the Danube.

On August 11, 2006, a bunker fuel tanker,carrying over two million litres of fuel sank inthe southern Philippines and has leaked over200,000 litres of fuel onto the coast of
Guimaras Island.
According to reports from the Philippines, thetanker is over 600 metres below sea level andcontinues to leak fuel and is still spreading in
other islands; approximately 4,000 familieshave been affected and/or displaced by thespill. Local efforts have proven difficult to capthe leak in the tanker and there has been no
successful effort to remove the tanker from

Teams of workers evaluate theconcentrations of the chemicals, whereand how people might be exposed, andpotential toxic effects on the exposed
peopleemergency response teams are on
twenty-four-hour call;
if a spill occurs, they use source data(such as the hazmat placards on trucksand tanker cars), databases of chemicalproperties, and chemical movementmodels to rapidly predict the movementof contaminants and the toxicity of the

If rapid spill cleanup is necessary, theemergency response team designsand implements cleanup measures to
protect exposed populations andecosystems from toxic responses
Small spills on land are cleaned up bysimply excavating the contaminatedsoil and moving it to a secure landfill.
Oil spills on water are contained usingfloating booms and adsorbents, orsolid materials that capture the soil,
so that it can be disposed of in

What NEVER to do in the Event of aMercury Spill
Never walk around an area that iscontaminated with mercury. Mercury is easilyspread and the spill area may not be easilyidentified. Contaminated clothing can alsospread mercury around.
Never use an ordinary vacuum cleaner toclean up mercury. The vacuum will putmercury vapor into the air and increase
exposure. The vacuum cleaner will becontaminated and will have to be disposed ofas hazardous waste.
Never use a broom to clean up mercury. It
will break the mercury into smaller droplets
